This is the business part of the plumbing. From bottom right (which comes out of the PHE), we have drain cock, pump, flowmeter, filling point, check valve with bypass, then T off to pressure guage and EV. Solar return is out the top. The pump is the Davies-craig 'EBP' which provides flow rates from 2-24l/m (2-24W), so should be lower consumption than a conventional CH pump.

This shows the PHE fitted in relation to the hot water tank. It is attached at the coldfeed pipe and the vent pipe. This is supposed to thermosiphon sufficiently to move heatinto the tank. This arrangement is something of an experiment to see how well it works with an existing tank.
