Suggestion for a thermal store?

[siricosm]

I am moving house and looking to install a thermal store in the new place. I was thinking of an unvented store around 300l, with a single corrugated stainless coil for DHW.

Any suggestions on make/model/supplier?

Big difference between a thermal store and an unvented, which one ?

 

[siricosm]

Unvented thermal store, normally pressurized at 1.5-2 bar. Boiler heats water in the store, and DHW coil is used for mains pressure hot water.

Are you looking at multiple heat sources?

You never know what the future will bring, but for now it will only be used with a gas system boiler. The house currently has a vented copper electric cylinder for hot water, and an unvented system boiler for the radiators.

I think all we can do is remove the pic not cut it done. You may have to remove the pic and repost mate

Thanks KOP, the Joule looks very nice. Although I would prefer something with a large internal coil rather than an external exchanger. The coil in my current OEG cylinder is 4.5 sq m, although maybe the plate exchanger on the Joule is even bigger? I guess that would allow the tank to run at a lower temperature.

The Joule also has a stainless tank, my current OEG is plain steel, only the coil is stainless. Of course the OEG is cheaper (~1/2 price), but it will not fit where I plan to put it.

Do you buy direct from the manufacturer?
