Heater Can Assembly
Which power rating should I choose?
Many of our electric showers are available in a range of different kilowatt power ratings, ranging from 7.5kW up to 10.5kW - ratings are lower for Instaflow water heating and Instaflow T30i handwash units.
But what does this mean to me?
Basically the higher the kW rating -- the higher the flow of water from your shower head.
For example — a 7.5kW shower giving a 40-degree Celsius shower in winter will deliver a flow rate of around 3 litres per minute. By comparison, a 10.5 kW shower can give 50% more flow from the shower head than a 7.5kW shower. Our short video demonstrates what this difference looks like.
What should I check for before selecting a power rating?
Before selecting your unit's power rating, you will need to check the following;
- Water pressure and flow rate
- Rating of the miniature circuit breaker or fuse in your consumer unit
- Size of electric cable running to your shower.
Why?
A higher kilowatt shower will have greater installation requirements than a lower kilowatt shower, therefore, you may need to upgrade your shower's electrical system to support a higher kilowatt shower.
The table below shows an example of the different typical requirements for a 7.5kW and a 10.5kW shower.
| 7.5kW electric shower | 10.5kW electric shower | |
|
Pressure/flow rate (bar/litres per minute) |
1 bar delivering 8 l/min | 1.5 bar delivering 11 l/min |
| Miniature circuit breaker (MCB) rating (Amps) | 32A | 45A |
| Cable size (mm²) | 6mm² | 10mm² |
How do I find my existing shower's power rating?
You can find your existing shower's power rating (kW) by checking the rating label on the underside of your electric shower unit (near the shower hose outlet). It should appear similar to the below example.

Made a order online for a part for my triton shower, the thermal switch had failed so needed a new one ASAP. Delivered within a couple of days so everything back up and running again. Good products, good service and delivery was spot on.

Ordered a stabiliser solenoid/flow control valve which arrived as promised but when fitted, allowed water to pass when the solenoid was deactivated (just a drip but not acceptable). Contacted the sales team and told them the problem. Response; immediately put another valve out for delivery, no problem. Great customer service, thanks.

Very easy to find the part required from their website. Ordering was straightforward, as was payment and delivery options. Took a couple of days to receive, which was ok. Packaging was just an unpadded bag, which was odd, given it was a sensor, so presumable sensitive. Surprised it wasn't in a small box.

The parts store on the website is simple to navigate and easy to order from. Deliver time was as described and part(s) arrived perfectly. The added instruction manual was a brilliant touch, providing a step by step guide to fixing the issue. Not seen this kind of service with spare parts before, so it was much welcomed.

The order was taken and acknowledged efficiently online, as you would expect. Based on previous experiences with the delivery company (Evri), I chose to have the product delivered to a Post Office instead of my property. This added 5 days on to the delivery date (don't know why).

Contacted Triton with a model in mind. Staff advised me of another model that they thought would be better for me. They were bang-on. Only quibble is the amount of time spent trying to speak to an advisor.

Part required urgently, received replacement next day. Have purchase 6 Triton showers over 30 years, it is the first time a Solenoid Valve Assembly has failed. Not sure if 5 years is a reasonable life expectancy for T80si shower but that's my experience. Have extended the life of 3 by purchasing serviceable parts.
