Hi,
I hope someone can help with the following issue:
Re: Vaillant ecoTec Pkus 428 - not a combi
My Vaillant ecoTec Plus boiler radiator setting is set to max 75 c. However, the the boiler will only reach approximately 45 c even though the house thermostat has not reached temperature. It just ticks along at that, but goes up for short bursts when the fan kicks in.
I have noticed the following:
1. If I turn the water heating on the boiler then heats to the correct radiator temperature i.e 75 c.
2. If I turn the water heating off the boiler will continue to meet the 75 c heating requirements working with the house thermostat.
However, as soon as the Boiler is not active for a period of time i.e The thermostat is turn right down so the boiler is not required to work for a time, I then hit the same original issue. That is, the boiler just runs at approximately 45 c and the house takes forever to heat up.
Any help on this would be really appreciated...
One final question. I noticed a post that the pump should always be set to 3 - is this correct as mine is set to 1. When I had it set to 3 the central heating was overflowing.
Thanks for any help / diagnosis.
Cheers
Matt
