Viessmann boiler failure

[ppppenguin]

I remember Jeremy getting his new boiler as he wrote about it on another Forum.

I (Jeffrey) got a new boiler about 5 years ago. I don't recall Jeremy (aka Pamphonica) getting one and writing about it.

Since I did the installation myself I reckon the new boiler paid for itself in under 4 years due to reduced gas usage. Install cost a little over £1000. Unless it's a distress purchase (old bolier gone badly wrong) then the economics are less good.

If a decent boiler is installed properly (obviously I didn't clean my system well enough) then it's still the cheapest form of heating if you have mains gas. Best makes are Worcester-Bosch, Viessmann and possibly Vaillant. Avoid most of the others.

Actually the best form of heating is to upgrade the insulation on your house so you don't really need central heating. This is neither simple nor cheap but the idea of effectively zero heating bills is very attractive. Passivhaus is mainly applicable to new build but there is a related scheme for retrofit. Only worth doing if you are doing a very major refit on your house. https://en.wikipedia.org/wiki/Passive_house
