Central heating won't work during summer

[richie51]

Hi, I have a vaillant boiler. Now the weather is warmer the central heating won't work. I have hot water only. I can't get the radiators to come on again until the autumn. Is there anything I can do to make the radiators come on just for an hour in the morning during summer. I've had it serviced and it works normally all year round, but for years it's always done this. Often when the weather is just starting to get warm the radiators will stay on for maybe an hour then they shut off. In the winter they stay on as long as I want them to. Now in June I can't get them to come on at all. Any advice. I'd just like to get them to work for maybe an hour some mornings. Thank you.

Do you have a timer for the system?
If so, what HW and CH options are available?
Do you have a thermostat on the wall (normally hall or living room)?
If so, what temperature is it set to?

Turn the room thermostat up. Or does boiler have summer and winter mode. i.e. does it have hot water only selection?

I'm thinking maybe it has weather comp installed ??

Three weeks ago an ecotecpro24 was installed in my flat. hot water working fine. When I turn on the central heating the boiler runs for a couple of minutes, but as soon it reached the set temperature [50 degrees], it switches itself off. Once the burner anti-cycling time is over, it would do so again and agin, without running continuously. Any suggestion? Thanks!!

Could be a few things do you know if the benchmark was filled in (in the back of the installer instructions)

 

[Filippo]

yes, it was

And... roomstat?

 

[Filippo]

yes, that is working fine

 

[Dilalio]

yes, that is working fine

I meant do you have one!

Call the installer back. Heating should have been tested on completion of that, by both parties.

yes, I do have a roomstat and it works. Thanks for the advice!
