Why choose a Swimming Pool Heat Pump?

You should choose a swimming pool heat pump simply because it’s inexpensive - to buy - to run - to install. Generally, the main heating systems available for swimming pools are Gas (LPG or Propane), Electric or Oil heaters. Some of these heaters can be beneficial from a cost point of view but tend to loose their appeal when it comes to installation costs. What the other heating systems cannot offer you is both the heat efficiency and low running cost!

Affordable swimming pool heat pumps for all swimming pools.

Let's face it, in this country, all swimming pools whether above or in-ground, need heating to obtain the maximum use from the summer season. Having a pool in your garden may be aesthetically pleasing to the eye but unless the pool feels warm and inviting, the pool will not be used to its full potential.

How does a swimming pool heat pump work?

 

Swimming pool heat pump working process

 

Swimming pool heat pumps are a super efficient way to heat the swimming pool. It makes full use of the advanced refrigeration technology to capture the heat in the outside air and transfer it to the pool water.

Environmental refrigerant gas absorbs and transfers the great heat energy through the refrigeration circulation system.

The swimming pool heat pump fan circulates air through the outer Evaporator Air Coil that acts as a heat collector. The liquid refrigerant in the air coil absorbs the available heat in the air transforming it to a gas. The refrigerant gas is then pumped by the Compressor.

When this warmed gas is compressed, it intensifies or concentrates the heat.

This intensely hot gas is then pumped into the Heat Exchanger Condenser where the actual heat exchange takes place.

As the swimming pool water passes through the Heat Exchanger, the hot gas gives up its heat to the cooler pool water.

The refrigerant returns to a liquid state and is pumped through the Expansion Valve and then into the Evaporator Air Coil to start the process over again.

A swimming pool heat pump does not generate heat, it simply captures it and moves it from air to water thus, providing an efficient and environmentally friendly system for heating your swimming pool!

How efficient are swimming pool heat pumps?

Swimming pool heat pumps don't have a simple efficiency number to work with. Their efficiency is measured by Coefficient of Performance (COP).

Our swimming pool heat pumps COP ranges from 4.42 - 5.6.

This means that for every unit of electricity that you put in to run the compressor you will get 4.42 units of heat out of the swimming pool heat pump.

 

Swimming Pool Heat Pumps can radically improve the energy efficiency and environmental value of any heating system that is driven by primary energy resources such as fuel or power.

Frequently Asked Questions

What is a Soft Start Kit?
A soft start kit is sometimes required to boost or power up your Heat Pump . It is normally only required if you are in a remote location. Your electrician will advise if a soft start is required.

When I use a heat pump, is a solar cover required?
Yes this is very important as it will reduce your heat loss up to 50% -70%. The use of a solar blanket will help extend your pool season.

What is the minimum operating temperature?
Alto and Competition swimming pool heat pumps will actually operate down to an ambient temperature of 0.C but with minimal heat output. Therefore we recommend that the minimum operating temperature should be 5.C.

Will the heat pump need more refrigerant gas?
The refrigerant gas should last for the life of the unit. If your heat pump needs refrigerant it is normally due to a leak, call your dealer for advice if this is the case.

How near to the pool does the heat pump have to be installed?
A heat pump should ideally be installed no more that 10m away from the swimming pool.

This chart shows exactly what percentage of your £1 will be used to produce heat in your pool.

What Pool? What Size?

Selecting the right heat pump size is important. Please see the chart below for a guide.

To heat your pool adequately, you will have to run your filtration for a minimum of 12 hours per day throughout the season.

The chart (below) assumes there is no high water table and the use of a solar heat retention cover.

Solar covers prevent heat loss from your swimming and can also assist with heating your pool using sunlight. As much of 70% of heat lost from you swimming pool is through evaporation, a solar cover acts as a water vapour barrier, stopping evaporation therefore dramatically reducing heat loss. When using a solar cover with a heat pump, the solar cover will reduce your heating costs.
