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.
