Hotwater

[Nour2022]

Hoping someone can help. We have just bought a house with a ideal boiler( new 2021) that seems pretty good, energy efficient etc. However, for some reason whenever I put the heating on, the hot water heating light comes on too! It will not let me run the heating without having the hot water on as well. It does let me have the hot water on and not the heating. The controller is Drayton lifestyle lp241and the hot water tank has a thermostat. Any ideas?

I don’t know the answer, but our boiler is the same. Hot water on its own or heating and hot water combined.

I think the 241 can accomodate hot water only plus heating only. However it will also work for hot water only plus hot water and heating together depending which setting its on. I'm pretty sure that on the back of the programmer when removed from its backplate is a little switch marked 'P' (pumped) and 'G' (gravity). It's just a little swich that manually needs to be moved over and suspect it had never been set correcly when installed.

In the P setting the heating and hot water will work independently and in the G setting they will work as you've described. Assuming that is that all the external controls are present. It being a modern boiler they should be.

The LP241 should be able to do HW and CH independently.

It may have a switch on the back for pumped/gravity (not visible) which is set on old systems which cannot have CH without HW. This should not have been set unless a modern boiler was fitted and the rest of the system not updated.

What colour is your hot water cylinder?

When you have time, please photograph tbe pipes, wires and other devices around the cylinder (and the boiler, if any)

I am particularly interested in a motorised valve, if any
