Hi, can you please tell me the name of your heating system and how it works? I am hoping to build a house in the next couple of years and looking into all the information I can :-) Thank you

The heating system doesn't have a name as such. But it works like this:

The HWC (Hot Water Cylinder) will be heated primarily by solar evacuated tube collectors in summer and boosted by a Rayburn solid fuel cooker. The Rayburn will then be the primary heat source for the HWC in winter with there being less sun about.

The DHW (Domestic Hot Water) will be on 2 separate piping circuits. When the HWC is up to temperature, any further heat coming from the Rayburn's own backboiler, is automatically switched and re-routed to the 2nd circuit with all 6 of the radiators and 2 towel rails connected to it.

It's pretty simple really, what's difficult is ensuing pipe-sizing. lagging and HWC position are as optimal as you can make it.

We were quite conscious of these things and made sure we used a company that had done CH (Central Heating) with a Rayburn before.

I hope that helps you out :-)

Thanks so much for that, I will have a look into the Rayburn but sounds fantastic! Have a great weekend :-)
