Elektrisk spa varmer

Activ Pool has spa heaters with effect from between 1.0000 and 6,000 watts.

A heater at 2,700 watt heats 200 liters of water up from 15 to 39 degrees in about two hours, and the largest heaters will do the job on roughly half the time. The water in the Spa should be kept to 38-40 degrees.
