Vaillant EcoTec problems

[laurenrose]

I wonder if anyone can help me?
We've been having some issues with our boiler and heating system for some time and we feel like we've tried everything! We have a Vaillant EcoTec boiler, but none of our radiators are getting warm. Occasionally they will get warm enough upstairs (our central heating system was put in with the rads upstairs being some of the first in the system, then coming downstairs) but the last rads in the system downstairs never get warm. We have had the pump changed in our boiler, a system flush and constantly rebalancing the radiators. Do you think maybe we are in need of a new boiler? It's roughly about 5-10 years old we believe, as we have just moved into the house. Or maybe a problem with our system, as it appears to have been set up strangely? Thanks

Have you had an engineer look at the boiler and system ?
If so what was their diagnosis ?

We had someone look at it a few months ago and they were just as confused as us to be honest. They were the one to suggest changing the pump, flushing the system and rebalancing the radiators. They also noted the arrangement of our system was odd, as it starts in our kitchen, goes to the rooms upstairs, then back down to our hallway and finally living room.

You need to find an engineer who knows what they are doing. If the boiler is working as it should ,then it's a circulation problem. Shouldn't be that difficult to establish which.
How old is the property ?

Thanks, we do have someone different booked in for next week to see what they suggest, but i'm just at my wits end with it not working. The boiler seems to be okay on paper. It heats up fine and not making any strange noises, which is what makes me think it's maybe the system.
From what I can remember it was built around the 1930's. The last engineer seemed to think the central heating was installed in a way which was convenient with the old arrangement of the old heat pump, rather than in an efficient way to today's standard.

The house built 1930's, or the heating system?

Sorry the house was built 1930's, not sure when the central heating was installed. But we know there was defiantly a heat pump at one time.

The property use to have a heat pump (sorry if i've got this name wrong) before central heating was installed.

Please add some photos of the installation, plus your radiators.
