Heater Can Assembly (from 2010)
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.

I ordered a couple of components for our shower and found the Triton website to be very straightforward and user friendly. Quickly identified the parts I needed and ordering couldn’t have been any easier. They arrived as stated within the timeframe and it was as easy as that.

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.

It was easy to buy the shower online, but when it arrived I was not impressed with the box, as it was damaged and easlly opened at the bottom, plus it was taped at the top. I could not call the delivery person back, as the parcel was dropped against my door, they knocked and ran. All of the parts were there, and it seems to work ok.

Triton dispatched the order very promptly on both occasions. The courier failed to deliver the first one, so Triton reimbursed me promptly so that I could reorder. The courier managed to deliver the second one after a delay of only a couple of days.

Temperature control works much better than the one it replaced [ same model]. this one came with a shower head which appears to reduce the flow rate and when it is switched off drains the head which will hopefully result in less black deposits on the head.

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.
