Heat Pumps

What Size? What Price?

Normally, heat pumps are sold for use in the summer season only. Yes, all the manufacturers state that they will work in ambient temperatures from 0-5 deg but will have minimal heat output, and realistically, at these temperatures you will be unlikely want to be swimming. Ideally, a heat pump should not be switched on until the ambient air temperature has reached 15-20 deg.C

Heat pumps are ideally suited for heating your pool in the summer season only (May – September). However, with various climate changes that we have been experiencing in recent years, we have had reports from our customers that they have been running their heat pumps from April to late October!

Unfortunately, sizing the heat for your swimming pool is not an exact science due to so many variables such as the thermal value of the pool structure, wind speed, water velocity, water table etc and if a heat retention cover has been applied.

Therefore, heat pump manufacturers base their calculations on the amount of heat (kW) your pool is likely to loose on an hourly basis. You will see that on some pool sizes we recommend two sizes of heater. If your budget allows, it is desirable to buy the larger size, due to it being more cost effective, efficient thus resulting is a quicker heat up time.

The sizing chart below assumes the following:-

• 15 deg C / 59F ambient air temperature (Realistic for start of season)

• Average wind speed 2.5 metres per second

• Desired water temperature 30 deg c / 86F

• Average pool depth 1.5m / 5ft

• No water table surrounding pool structure

• Minimum running time 10 hours per day

In the event that you are not able to meet the above criteria or for a more detailed analysis on heat loss or to size another pool please use the online guide www.paramountpoolsonlineguide.co.uk Here you will be able to access the ‘Swimming Pool Heat Loss Calculator’.

Please do not be misguided by high COP claims from other manufactures. Many of these claims are based on ambient air temperatures of 25 degC / 77F
which we feel are unrealistic at the beginning of the season
