Thermal Store

[sirocosm]

I plan to use an oversized boiler that directly heats the store water. This way I can keep the store temperature low (60C), and still have lots of hot water as the boiler will be able to replace the heat as it is used.

So what I am looking for is a small store (300l or less) with a large coil (4 square meters or more).

If you told us a bit more about your planned setup and what you're trying to achieve, it would be much easier to help you

I hope this helps. This was the layout of the system in my previous house (not in the UK) which I would like to duplicate here.
