Hot water new boiler

lil_old_me

Hello everyone. Long time lurker, decided to join!

Quick question hoping you can help with. Recently had a boiler installed but the hot water is not hot enough. Its coming out from the taps around 45 degrees Celsius. Is this normal? Doesn't feel hot enough to me?

I thought it had to be 60 degrees in the cylinder?

One assumes that as you mention a cylinder, you actually have one, rather than a combi boiler?

Check that your boiler stat is set to a minimum of 65C and the cylinder stat is set to 60C

Hi there

Yes its 60 on the cylinder stat

So how long is the boiler timer set for? Also have you increased the temperature setting on the boiler?

Hi

It was for hour and a half normally. It was on today and I tested it straight after the time it had heated water. Its about half on, on the boiler gauge itself

You could try turning up the temperature knob on the boiler a bit, to see if that helps.

The 60C figure is to prevent Legionnaires disease, which loves warm water, but is killed at 60C. It's actually unpleasantly hot when trying to wash your hands.

Thanks everyone for your help

Surely the boiler is not working properly if its just been on and its only coming out at 40 - 45 degrees? Its lost 15 degrees from the cylinder to the taps

It will depend on a few factors.

How long is the "Dead leg", -the length of pipe work between the cylinder and tap- .

How long since you last used that tap, to name but two.

If the boiler is not hot enough the tank will never reach its target temperature.

I would say it is not getting to 60C in the cylinder in the first place.

What boiler is it? How old is the cylinder?

A dead leg is a length of pipe that is capped off on the end, not the run of pipe between the cylinder and the tap.

well i'm not sure what you call it but to the rest of the plumbing world a dead leg is a long run of pipe between the cylinder & an outlet, not one that has been capped off.

OP if it's a new boiler installation i would get the fitter back to rectify your problem.
