Spa Circulation Pumps
Circulation pumps are used on many spas to save energy and help attain better water quality. Typically they are small units that pull from the filter and push through the heater in a constant flow.
This keeps the water clearer, as it is always moving through the filter media. The heater comes on and off as needed, and is called a ‘low-flow’ type heater as the movement from the smaller pump is slower.
These quality Laing circulation pumps are super quiet and operate on 115 or 230 Volts, but at a very low amperage draw (maybe 1-3) to keep electric costs low.
