ESP2 Electronic lime scale reducer (high capacity)

As for ESP1 but with the following differences:

More powerful unit will treat up to 250 litres water per minute. This is a powerful ?full system? scale reducer for entire houses (heating and domestic hot water) and entire dairies where multiple units need to be protected.
2 independent pairs of aerials attach to 2 independent water circuits (or ?doubled up? on a single pipe).
Variable control to alter the frequency/intensity of the scan.
No maintenance, around ?5 per year electricity costs.
Simple installation, wind the two/four aerials around the water feed pipe switch on, and ready to go.
Fit to all types of water pipe except lead.
