Last week my house was getting chilled so I turned turned on the central heating and my house warm up as expected. I then decided to turn on the hot water but to my surprise few hours later I noticed that I was not getting hot water in any tap.
Once the house warm up I turned off the heater and turned on the hot water and I started getting hot water again!! As a way of a test I turned on heater but non of the radiators warmed up.
So I concluded:
1.- In order to have hot water I have to turn off the heater
2.- In order to to have the heater I have to turn off the hot water
3.- Which ever service is turned on "first" works fine but not the second
Additionally I find very strange is that in the past when turning on or off the heater and/or hot water I used to hear a clear "click" coming from the programmer but with this recent problem I only hear the "click" which ever the first service is requested (hot water or heater) but not the second click for the other service. I do remember very well hearing both clicks in the past.
To try to fix this problem:
1- I have turned off and on the entire system for few minutes but the problem continues.
2- I have checked the system pressure to be around 1 bar
3- I have make sure the programmer is overridden so both water and heater are "on".
I have installed in my home:
- Boiler Remeha 30s avanta plus system in the kitchen
- a Honeywell programmer in the airing board
- a Honeywell thermostat downstairs
- 2 Honeywell motorized diverter valves model V4043H 1056
- an Unvented cylinder Ariston Primo HE ITI 250
I will appreciate if someone could give me a clue on what could be wrong with my system as unfortunately my installation is out of warranty .
