Vokera 24, hot water heats rads too !!!

[antilagman]

Can anyone help, i have a Vokera Linea 24 and the past year everytime you run the hot tap for a while the rads start getting hot ! even when the boiler is switched to hot water only?
Also, cause i havent used the heating this year and now i have started to, there isnt any pressure in the boiler? i have to refill the boiler every week.

I am assuming when we run the hot tap its getting through a valve to the heating system and also draining it?

can anyone advise

diverter is passing....20 minute job. there is a water leak somewhere.....find it.

what does the diverter look like, is it something anyone could change? and i am sure i dont have a leak ! when i went away for a week i came back to a full boiler as soon as you start using the hot tap it starts going down???

diverter is easy enough if you are reasonably handy. would mean draining the boiler and removing the diverter head and innards.

put your fingers on every rad connection when the system is cold, its the only way to be sure there isnt even a small drip, looking for puddles on the floor is no good. check the PRV pipe to outside isnt dripping. check the boiler isnt leaking underneath.
