Corrosion resistant case

The Hydro-Pro ABS range is made of high-quality materials including a stylish black corrosion resistant ABS case and Titanium® heat exchanger, which are resistant to damage from chlorine or salt. Accessories include rubber feet to help reduce noise and wear and tear from vibrations and a winter cover.

Simple, quiet operation

An LCD display allows easy operation and all functions are microprocessor controlled. Hydro-Pro heat pumps are quiet running due to the use of a low noise rotary compressor and fan.

Full installation guidelines are provided with the heat pump, a motor rated MCB is required due to the increased full load current when the compressor starts up, all electrical wiring should be carried out by a qualified electrician. Water inlet and outlet connections are 50mm across the range (we supply bushes to convert connections to 1½ inch as standard), and the use of a bypass kit is recommended to control flow rate, for easy maintenance and for winterising the unit.

Efficient pool heating

The Hydro-Pro swimming pool heat pump is an extended season model and should be installed outside, this quiet running heat pump works by absorbing heat from the surrounding air which is then transferred to your pool, for each kW of energy consumed up to 6kW of heat is transferred to your pool when the ambient air temperature is 27°C, or up to 4kW at 15°C. A heat pump is the most efficient way of heating a pool throughout Europe.

As 80% of the energy produced is obtained from the ambient air you are saving money on running costs while still heating your pool. While these heat pumps operate in ambient air temperatures as low as -5°C, reduced heating efficiency and increased heat loss at lower temperatures mean it is not possible to achieve the same heating as you would during warmer months.

Installation Tips

Sizing your heat pump

When sizing a heat pump for a customer’s pool, the manufacturer’s maximum pool size is always our starting point, not the determining factor, whilst we carry the manufacturer’s specifications on our website, we do not recommend a particular heat pump based just on pool size.

The heat pump we recommend for your pool will always be based on factors including pool type, location, usage, insulation, whether the pool is covered when not in use, your expected swimming season and ultimately the temperature you would like to achieve.

Positioning your heat pump

Hydro-Pro heat pumps should always be installed outside, the diagram below shows the manufacturer recommended spacing around the horizontal and vertical heat pumps for the adequate circulation of air. Restrictions on air flow around a heat pump such as dense vegetation or solid surfaces such as sheds, fences or walls will lead to a drop in efficiency and heating ability, it especially important that cooled air can be properly dispersed away from the unit.

Reducing heat loss

We recommend that you should keep your pool covered when you are not swimming, 80% of pool heat loss occurs from surface evaporation. If you have an Intex style above ground pool it is especially important to keep the pool covered as these pools are not as well insulated against heat loss.

If your pool did not come with a cover supplied then a separate solar cover would be a worthwhile investment, otherwise any heat generated by the heat pump could be lost through surface evaporation and you will struggle to achieve your required temperature.
