Solartwin argue that 20% of the environmental benefits from their
competitors systems are lost due to using high power electric pumps.

Imagination have also gone for the low flow, low power, solar
powered pump approach.

Indeed. Did I see a figure of £3-4000 (installed) for a gas boiler
with Stirling engine electricity unit?

People's electricity meters, if they have one with an aluminium
disc, do indeed run backwards for much of the day. Of course they
don't run backwards very fast compared to how fast they run forwards
when a washing machine is heating water.

Or oil rigs, which are a rather smaller radar target than a wind
farm.
