Common questions and answers for this SuperHome

Have you had any problems with your pellet boiler?+

We are very happy with our boiler, we haven’t really had any problems with it. We bought it through Oxfordshire Woodheat who service and repair it when necessary – I would happily recommend them.

I do know that pellet boilers have evolved significantly since we got ours 6 years ago and now are much easier to clean out and repair.

How well does mechanical ventilation with heat recovery work in a less airtight house?+

We love our heat recovery system – though it is tricky to find anyone who will service it in this part of the country so we tend to do it ourselves.

In order to improve the insulation in our house we built a second timber-framed skin inside the house, which has helped to make it much more airtight.
