Plate heat exchangers

About 80 quid for one suitable for a heat bank application. That would be rated nominally about 100kW, although actual heat transfer rate is a complex function of temperature differences and flow rates.

Christian.

Something in the £80-100 range.

If you contact GEA, they will send you spec curves for the transfer rates. They are based on temperatures and temperature differences on both sides.

A small one is generally rated at 100kW at typical water heating use. You can get 200kW ones for not much more money and it doesn't matter if you oversize. For a heatbank application, the objective is to get maximum instantaneous transfer.

Smaller plates are available that go in combi's. Just look up the price of one with the flowrate of a combi similar to what you want.
