Waterco_UltralowSwimming Pool Heat pumps are a super-efficient way to heat your pool. They make full use of advanced refrigeration technology to capture the heat in the outside air and transfer it to the pool water.

Environmentally friendly

Swimming pool heat pumps do not generate heat; they simply capture it and move it from air to water thus providing an efficient and environmentally friendly system for heating your swimming pool!

Some other benefits of having your pool heated include:

  • You will enjoy your swimming a lot more. Warm water is inviting as opposed to cold, swim in comfort throughout the whole season.
  • Extend swimming season. Why use your pool for only two months of the year when you can use it regardless of the weather?
  • Automation.  Set your temperature and let your heat pump do the work.
  • Efficiency. Our systems are designed specifically for swimming pools which means that the components used offer maximum efficiency.

Does a swimming pool need a heat pump?

In the UK all swimming pools should utilize a heat pump, either air source or ground source, regardless of whether your swimming pool is above or inground.

Heat pumps are inexpensive overall. They are reasonably priced, easy to install and maintain and an essential item. Having a garden pool may be aesthetically pleasing to the eye but if the water is not warm and inviting you may not want to use your pool as often as you could.

How can I heat my swimming pool?

This is a question that lots of people ask. 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 lose their appeal when it comes to installation (and running) costs and this is why a air source or ground source heat pump can be a much better solution to heating a pool.

How does it work?

Essentially the process is similar to the way a refrigerator works. Heat is draw from the environment surrounding the heatpump which is then turned into heat for your pool.

How efficient is a water heat pump?

They don’t have a simple efficiency number to work with. Their efficiency is measured by Coefficiency of Performance (COP). COP averages at 5.25 across the range. This means that for every unit of electricity that you put in to run the compressor, you can obtain up to 5.25 units of heat out of the heat pump.

*COP is dependent on a number of factors, i.e water temperature, air temperature and relative humidity.

How noisy are heat pumps?

All heat pumps resonate some form of noise due to the fact that they require a circulating fan to draw the warm ambient air over the evaporator coils. Most heat pump manufacturers have developed their fan motor technology to such an extent that the decibel output is minimal.

Competition’s decibel noise level (dB(A)) ranges from 52- 61 dB(A) comparable to a dishwasher! However, respectful consideration must be to adjoining neighbours regarding installing any type of mechanical heater, be it gas, oil or an electric heat pump. What one noise level may be accepted or tolerated by one person may not be accepted by another!

In general the RA model is slightly quieter due to the nature of the fan that is used in manufacture. The RA has a plastic circulating fan as opposed to a steel blade meaning there is less noise produced.

If a noise level is of concern or if in doubt we would strongly recommend that the RA model is acquired and installed in an indoor environment.

How do I know that I am buying the correct size unit?

Sizing the correct heat pump for your pool is very important. We would recommend that you use our pool heat loss calculator http://www.paramountonlineguide.co.uk to determine how much heat your pool construction loses. You will then be able to purchase the correct size heater.

When I use a heat pump, should I use a pool cover or solar blanket as well?

Any reduction in pool heat loss directly translates into savings. 82% of all losses are due to evaporation. Using a pool cover just a night will save about 40% of the annual heating cost. A pool cover or solar blanket can cut total pool heat loss by 50% to 95%. The use of a solar blanket will also help extend your pool season.

What is the minimum ambient operating temperature?

Both heat pumps will actually operate down to an ambient air temperature of 0 degrees Celsius, but with minimal heat output. Therefore we recommend that the minimum operating temperature should be 15 degrees Celsius. Other conditions such as wind, shade and physical location will affect the shut-off temperature of the unit.

Will the heat pump ever need more Freon (refrigerant gas)?

Unless the heat pump has a leak in the sealed refrigeration system, the factory charge of Freon should last for the life of the unit. Freon is very stable and should not degrade or breakdown even under severe operating conditions. If your unit needs Freon, then it has a leak, and adding Freon will not solve the problem. The leak must be located and repaired. Fortunately, Freon leaks are very uncommon and usually are due to shipping damage.

How close to your pool?

Normally, the pool pump and heat pump are installed close together and within 25 feet of the pool. The longer the distance from the pool, the more heat loss from piping. Since normally most of the piping is buried, the heat loss is minimal for runs of up to 50 feet (50 feet to and from the pump = 100 feet total) unless the ground is wet or the water table is high. A very rough estimate of heat loss per 100 foot is 2500 BTU/hr for every 10 degrees Fahrenheit difference in temperature between the pool water and ground surrounding the pipe, which translates to about 3% to 5% increase in run time.
