If the mains water pressure is insufficient then a Triton T450i single impeller pump can be used to supply water to most electric showers. Alternatively an integral pumped shower such as the T90xr can be installed. However, these are not suited for a 10.5kw or thermostatic unit.
Note: pumped showers must be fed from a cold water cistern they must not be connected to the mains cold water supply.
Considerations when replacing an electric shower are:
Dimensions of the unit (will the replacement shower cover existing tiles and screw fixings)
Cable and water entry points (are they compatible)
Kilowatt rating of the unit (is the existing cable and fuse size adequate for a higher kW rating )
Incoming electricity supply to the property (is the supply adequate i.e. 80 or 100amp for a higher kW rating )
The T80z Fast-Fit or T80 Pro-Fit are recommended as a replacement for all previous models of T80 i.e. T80Mk3, T80i, T80si, T80xr and T80z.
The T80z Fast-Fit or T80 Pro-Fit are also ideal replacement options for other makes and models as water and cable entry points are on both the left and right hand side of the unit.
Alternatively, the T80z Thermostatic Fast-Fit includes all of the replacement features of the T80z Fast-Fit and T80 Pro-Fit, but also features thermostatic temperature control for a more precise and consistent showering temperature.
The minimum water pressure required depends upon the model and its kilowatt rating.
Some units will continue to operate at a reduced flow performance on a minimum running pressure/flow of 0.5bar at 8 litres per minute. However for full flow performance from all electric showers the following pressure and flow is required.
7kW to 8.5kW showers require a minimum running pressure of 1 bar at a minimum flow rate of 8 litres per minute
9kW and 9.5kW showers require a minimum running pressure of 1 bar at a minimum flow rate of 9 litres per minute
10.5 kW showers require a minimum running water pressure of 1.5 bar at a minimum flow rate of 11 litres per minute
The fuse size must be equal to or the nearest size above the kilowatt rating of the shower i.e.
7kW = 30/32amp mcb
7.5kW = 32amp mcb
8kW = 40amp mcb
8.5kW = 40amp mcb
9.5kw = 40/45amp mcb
10.5kW = 45/50amp mcb
Not necessarily, it will depend on the existing cable size and installation characteristics. A site inspection by a competent electrician is required to confirm if the existing cable and fuse will need upgrading.
It is possible to supply a number of mixer showers from one pump providing the following guideline is followed:
If three showers are supplied by one T22i pump, supply pressures will fluctuate when showers are being operated simultaneously
Thermostatic mixer showers should be fitted to ensure a stable showering temperature is maintained
Care homes generally follow NHSE guidance on the delivery of safe hot water temperature to outlets. Fitting a TMV3 mixer valve shower, such as the Elina TMV3 Bar Mixer will fully meet the requirements for the delivery of safe water temperature in this type of establishment.
In addition to the shower, appliances such as basins, bidets and baths will also require TMV3 thermostatic control on the hot water outlets.
The output from a thermal store unit depends on its size (stored volume), heat transfer capability and the water pressure entering the unit. Some are only capable of delivering sufficient hot water to one mixer shower whereas others can supply 3 or 4 showers simultaneously. Always check the specification of the thermal store before selecting any mixer shower to ensure that the capacity of the heating appliance is compatible with the shower and required usage.
It is not necessary to use a cylinder flange when installing our mixer and pump products. Teeing into the inclined section of pipe from the top of the cylinder is the preferred method of connection.Providing the tee is pointing down, air released from the heated water in the cylinder will bypass the tee and escape out of the expansion pipe.
If it is not possible to fit the tee in this fashion it can be installed in the falling supply to other outlets, providing it is below the expansion pipe tee and is the first take off point before other taps.
The principle is that for every 1 metre head of water, (as measured from the base of the cold water cistern to the top of the showerhead) there will be a pressure into the mixer of 0.1 bar. This is a theoretical pressure as restrictions within pipe fittings and the shower mixer valve will reduce the pressure to a degree.
Providing only minimal restrictions are present in the supplies and terminal fitting the additional measurement (height) of water within the cistern will usually compensate for pressure losses in the supplies.Where flow-rate is quoted for mixer valves at 0.1 bar this is an open outlet figure i.e. flow of water from the mixer outlet without the shower hose and showerhead fitted.
The easiest product to install would be the Satellites Sirona with LP mixing unit and Metis shower kit . The mixer unit can be installed just below the cold water cistern. Pumps in the mixer unit will deliver water at pressure to the showering area located above.
All of our power showers incorporate a pump and mixer valve, which can only be connected to low pressure gravity supplies. Connecting to the high-pressure mains fed combi-boiler will damage the shower unit. This combination also contravenes the Water Regulations.
With the exception of the T80 Pro-Fit, the range of mains fed electric showers and the T90xr pumped electric shower require a 15mm compression fitting to be used.
The T80si pumped shower has a 15mm push – fit inlet connection.
The T80 Pro-Fit can use compression fittings or push fit fittings, providing they are the demountable type.
No, an electric shower must have its own dedicated power supply.
If an under-rated fuse is used it will be overloaded and will keep tripping out. If the fuse rating is too large it will not disconnect the supply quick enough under a short circuit fault condition. To avoid these problems the correct size fuse/mcb must be fitted for the kW rating of the unit in accordance with the I.E.E. regulations. Sizes required are:
7kW = 30/32amp mcb.
The size of cable that can be used for an electric shower depends on a number of factors which includes, the kilowatt rating of the shower, the method of cable installation, any de-rating factors and the length of circuit. In some cases 6mm² cable will be adequate for a shower rated up to 8kW. For showers above 8kW it may be necessary to install 10mm² cable.
In order to comply with Part P building regulations a competent installer familiar with the requirements of the current I.E.E regulations must assess the proposed circuit in order to select the correct cable size.
You can either book an engineer online, or alternatively contact our customer service department on email@example.com or call 02476 324 779.
Yes, you can purchase shower accessories and spare parts direct from our Spares section or alternatively you can visit our online spares shop. You can also purchase them directly from our Shower Accessories section.
No, Triton manufacture and service shower products but do not offer an installation service. We recommend suitably qualified trades people undertake the installation.
Yes, there is a range of Triton bar mixer showers available with fixed head accessories including the Eden bar diverter mixer shower.
A thermostatic mixer shower provides a stable showering temperature when pressure or temperature changes occur in the water supplies i.e. when other taps are turned on in the property. If there is a total loss of the cold or hot water supply, there will be no maintained spray of water from the showerhead.A manual mixer shower does not react to changes that occur in the supplies and will not prevent changes in showering temperature or hot water flowing from the showerhead if there is a loss of the cold water supply.
Thermostatic showers, such as the T80z Thermostatic Fast-Fit offer precise temperature control, making automatic adjustments when water supply conditions alter thereby preventing any undue change in showering temperature.
No, you cannot fit a pump on the system because the combi - boiler is connected to the mains cold water supply. Shower pumps are suitable for gravity fed supplies only.
Proof of purchase is required to show to the service engineer when he calls. If this is not available, the manufacturing date code on the shower is checked.
How to clean the showerhead can be found in the fitting instructions for the model of shower that you have.
In some cases the sprayplate can be removed from the showerhead using a key that was supplied with the shower. The sprayplate can then be soaked in a proprietary de-scaling fluid.
If the sprayhead does not have a removable sprayplate then the head can be left to soak in de-scaling fluid for an hour or so to remove the scale.
Water continuously dripping from the showerhead when the unit is switched off indicates a mechanical fault inside the flow control valve or solenoid valve depending on the model of shower. These parts are non-serviceable and will need replacing.
Yes you will have to install a high pressure variant of the HOST/HOME digital mixer shower on the new system.
This will vary according to your water system and the type of digital unit and shower accessories you have, but typically you can expect;
The minimum size cold water tank (cistern) we recommend for one shower unit is 115 litres (25 gallons). Hot water storage will depend on a number of factors such as, time in the shower, flow rate of the shower and the stored water temperature and recovery time of the hot water cylinder. As a rule of thumb a digital shower delivering a flow rate of 16l/m will use around 11 litres of hot water a minute. Therefore, this will use up the contents of a domestic hot water storage cylinder containing 117 litres of which 93 litres is useable, in approximately 8 minutes.
The larger the hot water cylinder the better
The electrical supply will be from a 3amp fused spur connection onto the 30amp ring main or radial supply feeding socket outlets. In the bath or shower room a ceiling mounted pull-cord operated isolation switch can be installed in the circuit to provide an accessible means of isolating the mixing unit when not in use
Typically in the loft, in an airing cupboard or under a bath, all subject of course to relevant regulatory compliance. Should servicing ever be required the mixing unit must of course be fully accessible.
If you have a gravity fed system with a minimum 115 litres cold water cistern feeding the hot water cylinder you need to purchase a low pressure variant of the HOST/HOME digital shower. If you have a mains fed system e.g. combination boiler, unvented or thermal storage cylinder you will need to purchase a high pressure variant of the HOST/HOME digital shower. If you would like to install a digital shower to your cold mains water supply you need to purchase the Aspirante Wireless or T300si Wireless.
Yes providing the cold water cistern holds a minimum of 115 litres and the bottom of the cistern is a minimum of 100mm above the top of the HOST/HOME mixing unit and showerhead.
It should be noted that it would not be possible to initially prime the mixing unit with water if the outlet supply pipe from the mixing unit or the showerhead is positioned above or only level with water in the cold cistern. Providing water can flow under gravity to the shower outlet then removing the showerhead and lowering the shower hose into the bath or shower tray should allow water to prime the mixing unit.
The LP mixing unit must not be started until water is seen to flow from the outlet. This is because the unit contains a pump, which can be damaged if it is turned on without water inside it.
The HOST/HOME mixing unit is rated at 3 amps and must be taken from a local ring or radial circuit supplying socket outlets. The mixing unit must not be connected to the lighting circuit.
With batteries fitted into the Digital Controller, electricity supply to the Digital Processor unit turned on, the wireless connectivity between the Digital Controller and Digital Mixer Processor unit will be automatically undertaken.
No, currently the HOST/HOME is for point of use showering only. There will be no means of preventing mixed water going to both showers at the same time, one of which is unoccupied.
No, when a control panel has been associated with a mixer unit it will not operate other units in the property.
HOST/HOME digital showers provide thermostatic control of the showering temperature and if there is a loss of either the cold or hot supply the unit will switch off to prevent the delivery of uncomfortable hot or cold water. It will not be possible to resume showering until both hot and cold water supplies are restored.
Things to check:
Check that the boiler is capable of providing a minimum hot water temperature of 52ºC at a minimum of 8 litres per minute flow rate as detailed in the fitting instructions. Check this at the kitchen sink hot water tap.Also, check that the running water pressure through the shower is within the 1 to 5 bar operating requirement.
Check that you have installed the correct type of mixer unit. It must be a low pressure unit, not a high pressure unit. This detail is on the rating label on the mixer unit.
Check that the purge pin is in the off position in the control panel.
Check that air is not present in the water supplies to the mixing unit or the mixer unit itself.
Check that the mixer inlet filters are not blocked.
To establish the electricity cost firstly multiply the kW per hour tariff you are paying by the kW rating of the shower. The cost per shower is then dependant on the number of showers taken per hour.
Example for an 8kW shower unit.
Electricity tariff at 12 pence per kW hour multiplied by 8 = Total cost of 96 pence per hour.
Number of 5-minute showers taken in 1 hour = 12
96p divided by 12 = Total cost of 8 pence for a 5 minute shower
For most Triton showers, you can use push-fit plumbing except for the final connection onto the shower inlet, which must be a 15mm compression fitting to ensure a watertight connection.
In the case of the T80 Pro-Fit a demountable type push fit fitting can be used to connect onto the inlet.
Yes, for the purpose of future servicing of the shower a ceiling or wall mounted DP isolation switch is required. It is also good practice to isolate the shower when not in use.
Check that the commissioning procedure has been carried out correctly as detailed in the fitting instructions. Check the inlet filter is not blocked and establish that water pressure and flow meets the specified minimum.
The most likely reason why the unit is not heating the water fully is that a heating element has failed. The elements can be tested for continuity using a multi-meter. If open circuit a new heater assembly is needed.Note: If an element has failed other parts within the unit may have been affected it is therefore important to check all the electrical circuits in the unit for signs of failure
If the shower is under warranty request an engineer visit via this site or call 02476 372 222 to arrange a visit under the terms and conditions of the warranty.
Check the temperature control and power setting is on the correct setting for the time of year.
Check the temperature control (flow control valve) is regulating the flow of water through the unit, there should be a noticeable reduction in flow when turning towards the hotter settings.
The PRD is a safety device designed to relieve abnormal pressure from within the heater assembly of an electric shower when a restriction occurs on the shower outlet i.e. blocked showerhead, collapsed shower hose. If activated it will be necessary to fit a new one
If water is leaking from a clear plastic tube or small plastic elbow in the unit, then the Pressure Relief Device (PRD) has been activated. The most common reasons for the PRD to activate are that the showerhead has become blocked or there is a restriction in the shower hose. A replacement can be ordered from our online spare parts store or by calling 02476 372 222.
If the water is not leaking from the clear plastic tube, then isolate the electricity supply to the shower and call 02476 372 222 for advice.
The filter will be found in the inlet connection. In some units it will be necessary to disconnect from the water supply to access the filter.
A rating label is located on the underside of the unit, which includes the model name, kW rating and the manufacture date code. Inside the unit there is a further product-rating label, which has the same information and also the serial number.
No, all Triton pumps must be installed onto gravity fed water supplies only.
Certain spare parts may be available but it is usually more cost effective to replace the pump with the latest model.
No, as detailed in the fitting instructions the hot water connection can be from a tee fitting positioned in the horizontal section of pipe from the top of the cylinder or in the falling section of pipe feeding other outlets.
Yes, the electrical installation must comply with Part P building regulations and the plumbing must comply with the current water regulations/byelaws.
No, this type of shower must be connected to a gravity fed hot water cylinder.
You will need a 3amp supply. This can be from a fused spur unit protected by a 30mA RCD.
The recommended minimum cold-water storage capacity is 230 litres.
Yes, providing the chrome plating is removed from the section of pipe entering the fitting.
If the head of water is at or less than the recommended 75mm, it will take time for air to be purged from the pump. Ensure air is purged from the pipes before connecting them onto the unit. Do not operate the unit with the pump running for more than a few seconds as doing so may damage seals in the pump.
No, it will be necessary to alter the pipe arrangements to accommodate hot and cold connections in the unit.
Check that the unit is plumbed in to a dedicated supply of hot and cold water. If it is not then turning taps on elsewhere will cause fluctuations in temperature.Check that air has been purged from the pipes up to the inlet elbows (as per the fitting instructions).
There is no provision on a bar mixer shower to alter the thermostatic cartridge inside and have hot water entering the cold-water inlet. It will be necessary to alter the pipe arrangements and have the hot water supply on the left.
We do not recommend installing our mixer showers onto unbalanced supplies of this type. While most of our mixer showers incorporate a single check valve in each inlet there is always a risk that debris may enter the mixer and prevent the check valve in the hot inlet from sealing off. Should this occur mains water at pressure will flow into the hot supply forcing water in the cylinder back into the cold water cistern potentially causing water to overflow from the cistern and damaging property.
Triton’s Elina range of mixer showers has tamper proof controls. A tool to remove the controls is supplied with the valve.
The following fixing brackets are available:
Note: These are not suitable for all models
View our range of fixing brackets.
Firstly you will need to establish whether the mixer shower you are interested in is suitable for the water system in the property i.e. a low - pressure or high-pressure system.
By accessing the fitting instructions for the product you will be able to establish the flow rate from a graph detailing the open outlet flow rate at various pressures i.e. flow that will be available from the mixer outlet without the showerhead connected.
Alternatively you can contact our customer service team on 02476 378 495 who will be happy to provide the information you require.
Check that the mixer shower you select is compatible with your water system i.e. low or high pressure.
Check that the mixer you select is thermostatic in operation if you want optimum temperature control.
Check that the inlet fittings on the new mixer offer the same measurement between them as the existing mixer, if not it will usually be necessary to alter pipework to suit.
Check that the existing hot and cold supply will connect to the correct inlets on the new mixer i.e. hot on the left and cold on the right, if not it will be necessary to alter the pipework to suit.
The minimum size cold water tank (cistern) we recommend for one shower unit is 115 litres (25 gallons). Hot water storage will depend on a number of factors such as, time in the shower, flow rate of the shower and the stored water temperature and recovery time of the hot water cylinder. As a rule of thumb a low-pressure mixer shower will deliver a flow rate of 5l/m and will use around 3 litres of hot water a minute. Therefore, this will use up the contents of a domestic hot water storage cylinder containing 117 litres of which 93 litres is useable, in approximately 30 minutes.
If a booster pump is fitted to improve shower performance then the hot water used can be in the region of 12 l/m, which means showering time will be reduced to approximately 8 minutes.
The larger the hot water cylinder the better.
No, Triton mixer showers must have the hot and cold supply at nominally equal pressure. Connecting onto mains cold water can result in cross flow into the hot supply, forcing water back into the cold-water cistern with potential overspill and property damage.
Yes, there is no problem using push-fit plumbing when fitting our mixer showers providing ferrule inserts are in the pipe when making connection to the compression fittings on the mixer.
Triton bar mixer showers have check valves already fitted in the hot and cold inlets, so there is no need to fit additional check valves in the supplies.
Check that the hot and cold water supply connections at the mixer valve are correct. If you have connected to the mains cold water supply and gravity fed hot water supply this could be the cause of the problem.Check that the inlet filter in the hot inlet of the mixer is not blocked.
Fitting a T550i pump onto the system will significantly improve the performance of a gravity fed mixer shower.
Flow rate from mixer showers varies depending on the available head of water and restrictions within the supply and valve. Commonly flow rate is between 3 and 5 litres per minute. To ensure optimum performance from a gravity fed mixer shower the following guidance should be followed.
There may be debris in the mixer. If the cartridge in the mixer is damaged, it will need replacing - call the Triton's customer service department on 02476 372 222
Common reasons for this symptom are:
Check that the sprayplate of the showerhead does not need de-scaling - if it does, then follow the procedure set out in the fitting instructions.
Check that filters are not blocked and check valves in the inlets are working correctly.
