Fitting a Hot Water Temperature Display to a Potterton Powermax HE boiler.

Avoriaz

In our previous house we had a hot water tank in the airing cupboard heated by a boiler in the kitchen. It was easy to estimate how much hot water there was by touching the pipe at the top of the hot water cylinder or sliding a finger inside the insulation wrap.

We moved last year and our current house has a Potterton Powermax HE boiler with integrated hot water cylinder. It is basically a big metal box with a hot water tank and boiler inside. I can’t therefore do the same quick physical check to see if there is enough hot water for a shower.

In warm weather I just want a bit of lukewarm water for a shower. At present I am probably overheating the water just to ensure that it doesn’t run completely cold. Not very MSE.

I therefore want to fit a temperature sensor near the top of the hot water tank with a display that I can mount outside the boiler casing. Experience will then tell me if the water is hot enough for a shower.

Is such a thing made or is there something designed for a different purpose that would do the job?

Please note that I am not talking about the inbuilt rotary control that sets the hot water temperature. Even on the lowest setting the water is hotter than I need.

Thanks

You get plenty of thermometers that have the sensor on the end of a cable that you could slide under the insulation. Would that do the trick?

I've never seen one of these integrated boilers so I'm assuming you know its safe and easy to do the above.

the powermax is basically an unvented cylinder with a boiler built in, the temp knob you ref to is a blending valve allowing you adjust the amount of cold water that is mixed with the cold before it comes out your taps, these valves are very good at scaling up which may be your prob, i am all for saving money but i don't think your idea is a good one, do you really want your showering to revolve around constantly looking at your boiler to see if the water is hot enough, shower at 7 look at the boiler nope not hot enough go back & watch tv for an hr while it heats up, the cylinder is well insulated so you aren't gonna lose much heat
