Swimming Pool Heating with Electroheat Subzero by Waterco

swimming pool heater

The latest advancement in swimming pool heating, Electroheat Subzero heat pumps extracts latent heat from the surrounding air, intensifies it and transfers it to your swimming pool.

Electroheat Subzero uses refrigeration technology to extract heat from the surrounding air and transfers it to the swimming pool. Electroheat Subzero heat pumps only require electrical energy to operate a compressor and a fan motor, using low amperage in the process. The Electroheat produces over 4 times more heat energy than the electrical power it consumes.

Compared to gas and electric heaters, Electroheat Subzero uses just a fraction of the energy to generate the same amount of heat and unlike solar heating; there is no reliance on the sun as the latent heat in the air is used.

Generally swimming pool heat pump evaporators ice once ambient temperatures drop below 10°C, which negatively impacts on its heating performance.

The main difference between the Electroheat Subzero and Waterco's Electroheat heat pumps is the inclusion of an automatic hot gas de-icing function. When ice forms on the evaporator, the Electroheat Subzero's refrigeration pipe configuration is automatically reconfigured to allow hot gas to melt the ice off its evaporator; the Electroheat Subzero then reverts back to heating your pool with maximum efficiency.

Electroheat Subzero heat pumps will heat your pool even when the ambient air temperature is below freezing point (0°C).

Electroheat Subzero's LED control panel features a continuous digital pool temperature display and incorporates a self diagnosis system. In the event of a problem, the control panel will display diagnostic error codes.

Electroheat Subzero also features an option to switch from POOL to SPA mode automatically via an external water pressure switch or manually via a remote control.

The Electroheat Subzero is protected by an array of built-in safety devices:
Auto defrost control to eliminate frost on the evaporator.
Auto flow switch to shutdown the system in the event of no water flow.
High / Low pressure refrigerant auto reset to shutdown the system in the event of low or high refrigerant pressure.
Compressor protection via a time delay to allow the refrigerant to equalise before the compressor starts/restarts.

Electroheat Subzero's are powered by Scroll compressors, the most powerful, energy efficient compressors on the market and most importantly they are also the quietest.

Electroheat Subzero heat pumps are equipped with Titanium heat exchangers, which have a longer life expectancy than standard copper heat exchangers. Titanium offers total protection against erosion and corrosion, it is resistant to: chlorinated water, ozone, iodine, Baquacil, bromine and salt water.

The exclusive design of the Electroheat Subzero's heat exchanger creates an unmatched and powerful heat transfer source. Surface area contact with the heat exchanger is maximised by effectively circulating the pool water though its condenser tubes.

Electroheat Subzero has an extra large evaporator allowing it to extract more heat from the outside air maximising the heat pump's performance and efficiency. Its cabinet is constructed of heavy-duty UV-resistant proof ABS body panels that are impervious to rust, corrosion and deterioration.
