New Triton Novel SR - water lukewarm

Hippodrome Song Owl

Newly installed Triton Novel SR power shower is only lukewarm at max hot setting. Water from the bath hot tap is scalding hot so not sure why shower is tepid. There is great pressure from the shower.

I'll contact the company who installed on Tuesday, but just wondering if there's something obvious I'm missing?

This is my first experience of a power shower and I have to say I was also a bit taken aback at how quickly it emptied the hot water, even running lukewarm. It was stone cold with all hot water gone after a 10 minute shower. Is this normal?

If your shower was operating normally with say 100L og HW available then you should get ~ 15 minutes of showering at 40C even with the shower on its max flow setting of ~ 14LPM so difficult to understand only getting 10 mins of lukewarm water, presesume the cold water is from your cold water storage tank in the attic?, a photo of the installation might help.

I see two obvious possible issues.

First one is the dial stops around the 12 O clock mark. To move it all the way to very hot you need to push in the button on the temperature dial. This should have been shown to you by the installer.

Second one is installer put the dial on in the incorrect position. Assuming you had a tank of hot water at the time of the installation then installers would / should have picked up on it at the time of installation

Third possibility is faulty thermostatic cartridge but this is very unlikely

Last possibility is it's airlocked on the hot side.

Assuming you had hot water at the time of installation all of these should have been picked up on by the installer. It's not that difficult to run to the shower for a few minutes to test temperature at time of installation. If there was no hot water in the cylinder then he couldn't preform these very basic tests

Another thing to look at is how the hot is taken from the hot water cylinder. I have a stainless steel cylinder. It has a special feed for a shower. Water is taken quite a few inches below to top of the cylinder. My shower can run stone cold & I can still have piping hot water at the taps

Thank you for the comments.

Yes, I understood that to turn the temperature up past a certain point I need to press in the button on the top of the dial. That attached photo shows the position of the dial where I need to push the button to move any further anticlockwise.

I know little about how it was installed but I also assume the cold is coming from the attic tank. The house was vacant during installation as it was all bathrooms being renovated, but they had keys and were told to turn on/off immersion and heating as required for the 10 days they were working.

There is a pipe coming out of the hot water cylinder in the hotpress which is a few inches from the top, so what you say @Sleeper12 may be the case.

Drawing the hot from lower down in the cylinder explains why you can have cold at the shower and hot at the taps.

I would suggest the installer put the dial on in the wrong position. This would mean that the dial says it's on hot when in fact it's only on a lukewarm setting. This is a very simple fix. Download the installation guide. Page 17 is what you are looking for. It shows the correct position to fit the dial. You can do this without removing the cover

I tried again today, having left immersion on the bath setting for 2 hours, so there was a full cylinder of water - the shower was still only lukewarm. So there is something else amiss. The water is cold at the temperature safety stop point. One thing I noticed is that when you turn the temperature dial up to max, you get a 1 second blast of hotter water, and then it goes lukewarm.

I had a look at the attached instructions - I think I'll have to leave it to the experts - not sure I can even manage that level if diy. But thanks for the advice!

If the dial is put on incorrectly & you call Triton out, they will charge €90 because it's not a faulty shower. Definitely get the installer to have a look first. Two minutes will resolve this issue if it's just the dial

Looks like a installation problem, does the temperature remain lukewarm even if the flow is reduced right down to minimum?.

@Sleeper12 It's a specialist bathroom renovation company - they only finished work last week. It's them I will be calling, not Triton. Hopefully it is an easy fix for them.

@John.G Yes, the temperature stays lukewarm even on low flow.

John.G

Is the shower OK now?.

No. I can't get off work early enough to let the company that installed it in to have a look until next week unfortunately.

Just to update this - I finally managed to get this looked at today. As suggested here, the temperature dial wasn't in the correct position. It took 2 minutes to fix.

Interesting.

Our landlord installed two new Triton SRs for us recently.

Even with the showers at max cold setting the water from both the showers is extremely hot, almost scalding. Is there no 'anti-scald' on these - I thought there was on lots of showers. Water is also extremely hot in all taps since this re-plumbing work. Could it be that the thermostats in the cylinder are not working?

Lots of LLs use a handyman rather than a qualified tradesman. They also tend to shop around for cheapest quote. They result is someone who hasn't been trained to install the shower and are unwilling to read basic installation instructions.

I'd be extremely worried that someone who can't put a dial on correctly possibly did something dangerous with the electricial part of the installation. Many ignore the wiring regs and tap into the lights or sockets. You have someone standing in a puddle of water, in bare feet, using an electrical appliance. Following the regs can easily save a life
