I require a solar cluster and a small dc water pump.

The idea is to use black pipe as a solar heat collector and pump it through a swimming pool driven by the solar powered dc pump.

The object is to raise the water temperature over a period and maintain it at a higher level than normal thus extending the pool usage/ holiday season in Portugal, Algarve.

Could you recommend equipment for test purposes. Doesn’t need much lift –say 2 metres and volume throughput need not be much -say 100 galls/hr

Is that a solar powered water pump or a 12v water pump for a solar heated pool?
