HW/CH timer

Tristram

Hi folks,

I'm hoping to get some advice on the current hot water/central heating set-up in our apartment. Appreciate any comments/suggestions.

We have a digital timer that is supposed to allow us to programme times for the CH and HW. There hasn't been a need to use the CH yet and unless this winter is drastically colder I don't imagine we will use it this year either. We do of course need and use hot water on a daily basis.

I have programmed the digital timer to heat water in the morning. I recently noticed that we seemed to have a lot of hot water all the time so I re-programmed the timer to come on for only two ten minute periods in a week. However, we still have piping hot water all the time so I am definitely going wrong somewhere.

I have attached two photos of the timer set-up and tank in the hopes that they may be of some help. Should the immersion switch be left on all the time or will the timer work if it is left off?

Thanks in advance for your help!

That looks exactly like the set up in Island Key apartments.
No, your immersion switch should be off, there is no need for it to be on if you are using the heating system.
If you have the immersion switched off and the the time clock only running for ten minutes and you still have an abundance of hot water then most likely the problem is your motorised zone valve is not closing properly and is allowing the flow from the heating system to keep the cylinder hot all the time.

The immersion looks as if it's switched on 24/7 so it's heating constantly
The timer should work
Find with the immersion switch turned off

Thanks for this suggestion. The experiment is underway. I ran a bath for the OH to use all the hot water. If nothing else, brownie points for this! I've set the timer to heat the water for 30 minutes and will test after.

Thanks for the comment. This is a bit over my head but I will come back to it should the above experiment fail.

Thanks guys!

Thanks guys! You were correct. I've turned off the immersion switch and water heated using the timer function. I wonder how much of an impact this will make on the electricity bill given that the immersion had been on constantly.
