Air source heat pumps are an ultra-efficient, economical and
"green" way to heat swimming pool water. In fact, air source heat
pumps have the lowest carbon footprint and lowest operating costs compared to
other heating methods. For the most modern, efficient, reliable and
environmentally friendly heating of your swimming pool, we do not hesitate to
recommend our low cost air source heat pumps.
These clever machines work by taking "free" heat from the
fresh air around you and using it to heat water. They work in reverse like an
air conditioner, making the surrounding air cooler and transferring the
extracted heat into the pool water. They use the same principle as a
refrigerator/freezer, which has heat pipes on the back that dissipate the heat
absorbed from the food. The only electricity required is to run a small
compressor, which allows them to release up to five times as much energy as
your electrical supply consumes.

How do I choose?
Air source heat pumps have grown in popularity in recent years due to
low prices due to mass production, snowballing global energy costs and
environmental concerns. Inevitably there were some dubious suppliers and
manufacturers trying to jump in on the price cuts, and some who thought they
were saving money ended up making decisions they now regret. Our advice is to
stick to machines with verifiable records. There is a dizzying array of premium
heat pumps on the market, and quality-wise, you can't go wrong with any of the
units we offer. These pumps should be fundamentally as trouble-free as a
refrigerator freezer because they share similar technology.
Heat pumps are the perfect solution for economical summer heating. They
are best used during the 'summer' period from April to September, when outside
temperatures are usually warmer. While most pumps can operate in near-freezing
ambient air temperatures, the lower the heat they produce, the cooler the
temperature. Therefore, for all practical purposes, we do not recommend relying
on air source heat pumps once typical daytime temperatures are well below the
15°C mark. In fact, at these temperatures, you most likely don't want to swim
outdoors anyway. For indoor pools, you'll need to install backup heating after
the air source heat pump, and its thermostat will only kick in if your pump
can't handle it. We recommend a good electric pool heater to run at night
during "off-peak" electricity rates. We also highly recommend using a
solar or thermal cover to help insulate your pool.
Sizing a heater for your swimming pool is not an exact science due to
many variables such as insulation and wind speed. If your budget allows, always
want to buy the largest size as it is more cost-effective and efficient,
resulting in faster heating times. But please ask your electrician to check
that you have the proper power supply before ordering.
Although not usually necessary, it is worthwhile to have a bypass in
parallel with the heat pump. All it takes is two tees, a valve and a short
length of pipe, which we can provide. Reducing the flow through the heat pump
by diverting a portion of the pool water can help fine-tune the performance of
the heat pump and help it reach peak efficiency. The extra plumbing also makes
it easier to drain the heat pump when you're not using it in the winter, which
is essential to prevent freeze damage inside.
Heat pumps are best installed outdoors. If installed indoors, they must
have adequate and unrestricted outside air circulation. They must be installed
and commissioned by a qualified technician in accordance with current
regulations. It is recommended that you check that your power supply supports
your preferred power input before ordering. Test your water regularly to avoid
acid or limescale damage that could void your warranty. Heat pumps must operate
within their seasonal and waste flow design limitations.
