I had a new Vaillant Boiler (ecoTEC plus 831) and Weather Compensator (VRC 470f) fitted a while back but during the recent cold weather have noticed the house isn't reaching temperature.
I have the desired temperate set at 21oC but on cold days it can take hours for the house to reach this temperature when the outside temperature is around 5oC. I've noticed the radiators are generally warm but not hot and the boiler display shows the central heating water is around 40oC. The night temperate is set at 18oC and regularly drops below this level.
At first it though it maybe a problem with the radiators and plumbing which is quite old but now not sure as I don't think the boiler is heating the water hot enough. Surely when it's cold and the desired temperature hasn't been met the boiler should be heating the water up to 75oC?
Any ideas what could be causing this issue? Hot water provided by the boiler is fine.
Thanks in advance.
