Why is my hot water only lukewarm, but radiators are boiling hot?

[Michelle1972]

Hello,

I have a Baxi WM boiler which lives in my loft, which is working normally. This afternoon I have discovered my hot water seems to be virtually non existant, but the radiators are scorching hot. Everything was fine yesterday so not sure whats gone wrong

I turned the heating off leaving the hot water on, but after a while the radiators made noises like they had no water in them (if that makes sense...though they do have water in!). The hot water seemed to heat up a bit more though after that.

Later when I turned the heating turned back on the water cooled right down, so what could be the problem?
The hot water cylinder is only 5 or so years old. I really don't know much about plumbing. I have an 'Immersion Heater' switch which is also for heating water in the cylinder....correct? Why do you need one of these if the water is heated throught the boiler?? This is switched off though, has been for years.

Not sure if its connected but my very old shower 'Triton T80' is now set at No.8 to get the water to come out as hot as I'd like it.....guess this is due to its age?

I had problems recently with banging and juddering pipes and after investigating I found that I had knocked the switch on the pump from 2 to 3 so it was working full speed. Everything fine with that now I hope.
Any advice greatly appreciated, though I don't understand plumbing talk so try and make it as simple as possible....Blonde nad very dumb....Thanks

Hi Michelle

Like a lot of things it just not so simple to say which one. The difference between these showers is the flow rate that they will allow and still provide water at a decent temperature, the higher the rating the more water you will get. However, the bigger showers 10Kw will require a 10mm cable to be run back to the main fuse board if one is not already there.

The wiring regulations surrounding the installation of an electric shower are quite onerous.

To find out what you already have you could contact the manufacturer, or look for their website. Post the details here and someone may be able to help.

It is strongly advised to get a competent electrician to look at the existing cabling, they would then be able to tell you the biggest shower you can have.

Good luck
