The Number 1 choice for pool heating is the ever-popular ASHP (Air Source Heat Pump).

Using a heat pump to heat your pool can have a number of benefits. A heat pump is highly efficient, economical, easy to use, and will last. Not only that, the ASHP option is much more environmentally friendly than a gas or fuel heating system. In addition, heat pumps have a long service life meaning they are more cost effective in the long run.

How does a heat pump work?

A pool heat pump uses electricity and instead of generating heat that way, the fan draws heat from the air outside the pool. Warm air is extracted by the fan and circulated around an outer evaporator air coil. Liquid refrigerant inside the evaporator coil absorbs the heat and thus transforms it into gas.

The warm gas then gets pumped into the compressor, creating a very hot gas that then passes through the heat exchanger condenser.

The pool pump draws water from the pool, circulates it, then passes it through a filter to the heat pump.

As the Liquid refrigerant gas and water from the pool is pumped through the heat exchanger, the hot gas transfers its heat to the water. The water increases by 3-5 degrees as it passes through, and then the warmer water then flows back into the pool.

As the hot gas flows through the condenser coil, it returns back to liquid form, back to the evaporator and the whole process begins again.

Heat pump pool heaters work more efficiently if the outside temperature remains above 45–50ºF. The cooler the air, the more energy they use, however, since most people use outdoor swimming pools during the summer, this usually is not an issue. Heat pumps are therefore dependent on the outside temperature. There are however different types of heating options summer season, an extended season for all year-round heating is also an option. Heat pumps are efficient as long as the temperature is higher than the heat pump guidelines. They generate up to 5 kW of heat for 1 kW of energy.

Heating your pool with a heat exchanger

For the quickest way of heating your pool, we advise you to use a titanium heat exchanger. This is ideal for people who have a holiday home and don’t always have access to the pool. A titanium heat exchanger will heat up your pool in just one day, ideal for those sporadic swimmers.

Heat exchangers contain a corrosion-resistant heating element that is made from titanium. The electricity heats the resistor, which in turn transfers heat to the water flowing through the resistance.

This titanium heat exchanger is connected to the residential heating system, which makes it a relatively inexpensive heating system to install. High energy consumption is the biggest disadvantage however. If you were constantly using a heat exchanger to heat your pool, it could cause a huge rise in your outgoings. Furthermore, this pool heating method is less eco-friendly than solar collectors or a heat pump pool heating system. That said, the great advantage of a heat exchanger is that it can heat up the swimming pool water even at colder outside temperatures when the sun isn’t shining. For this reason, a heat exchanger is often combined with a heat pump or solar boiler.

With the titanium heat exchanger, the water is quickly heated to your desired temperature. You can then let the heat pump or solar boiler do the work to maintain the desired temperature without the pump having to be powered up all the time.
