Pool heat pump: Advantages, Installation, Maintenance
Installing a heat pump is an effective solution to extend the swimming season. Among swimming pool heating systems, the heat pump is the easiest to install and the most economical.
How does the heat pump heat your swimming pool?
The pool heat pump - or "PAC" - is an "air-water" type pump: it captures the heat contained in the air to transmit it back to the pool water. Placed outside the swimming pool, a first unit sucks in the air, which transmits its calories to a refrigerating fluid, in the liquid state. With the help of an evaporator, the latter rises rapidly in temperature and becomes gaseous.
A compressor then condenses the fluid at high pressure, which transmits its calories to the swimming pool water network, through a second unit. A pressure reducer lowers the fluid under pressure, which can then start a cycle again.
The system is powered by electrical energy.
All the advantages of a heat pump for your swimming pool
In regions with a mild climate, heat pumps are used to heat water when the sun's rays are not powerful enough: depending on the region, swimming could then begin as early as May and continue until the end. September.
In colder regions, heat pumps are sometimes necessary in summer.
And if during a heat wave, the water becomes too hot, the operation of the heat pump can be reversed to cool the water: it draws the calories present in the water to release them into the air.
Solar heating, electric heater, heat exchanger… compared to other swimming pool heating systems, the heat pump is in the least energy-intensive, therefore more economical and more ecological.
More expensive to buy, it needs very little electricity, it quickly pays for itself and has excellent performance.
All about installation, maintenance and use
A swimming pool heat pump is one of the easiest systems to install, and by itself, its installation can possibly require the intervention of a professional.
The outdoor unit must be installed in a spacious, well ventilated place: it must be at least 50 cm from a wall or a wall, so that the air can circulate completely.
You will also need to install a bypass, as well as a filtration pump at the flow rate corresponding to your water pump.
On a daily basis, check regularly that nothing is blocking or hindering the air supply, as well as the pressure gauge and, from time to time, the tightness of the circuits.
Finally, to keep your pump in good condition during wintering, you can cut off the power, bleed the hydraulic circuits, close the T-valves so that the water does not rise in the circuits, loosen the fittings and cover your pump.
TIP: For more efficiency
To optimize the performance of your heat pump, consider covering your swimming pool overnight: this significantly limits heat loss.
