Note: The SunSpring05, SunSpring07 and SunSpring10 come with a pre-fitted UK or Euro plug/RCD. The SunSpring14 exceeds the capacity of a standard UK 13A plug and so we recommend that the SunSpring14 is hard wired to its own 20A Type-D breaker.

14. Customer Feedback

"I am delighted with the SunSpring pool heater, which I have running beside my above-ground 12' x 24' Intex pool holding 30,000 litres.

A few details for your interest:

I run the heater between 8 a.m. and 5 p.m. every day. The pool heater is costing me around £50 per month to run - a pretty reasonable outlay, in my view.

I set the pool heater up on May 5th 2014. The water temperature was initially 14.5 C and within about four days it was up to 22 C. I use a solar pool cover at night and the water pipes to and from the pool are insulated with black pipe insulation.

I have attached a few pics. (zip file) which you are welcome to use on your website if you wish.

Kind Regards

Mike Garwood

15. Water Flow Rates

Please check that your existing pump and filter will deliver the flow rate required for the SunSpring heat pump.

If your pump and filter are too small, then we sell the Krystal Clear pump and filter sets with higher flow rates to suit the SunSpring heat pumps

Please Click Here to see pricing for these pump and filter sets

16. Automatic Time Clock

If you would like to automatically turn on and off the SunSpring pool heat pumps, then we also sell heavy duty time clocks which are suitable

heat pump time clock switch


Note: The Sunspring heat pumps do not have a built in flow switch and so must not be allowed to operate without water flowing through the unit. 

17. Pool Hose

You may need to purchase an additional length of pool hose to connect from your heat pump to the pool

We sell both 1.5" and 1.25" pool hose



18. Bypass Kit

If you do not plan to drain your pool in winter, we recommend using a bypass kit.

This allows you to isolate the heat pump and drain it down whilst keeping the water in the pool

We sell a bypass kit for above ground pools which comes complete with hosetails, short lengths of pipe and glue etc

20. How to Calculate Your pool Water Volume

You can easily calculate the water volume in your pool as follows:-

Round Pools

To calculate the volume of a round pool, you can use the formula

Pool Volume = 3.14 x radius x radius x depth

  1. Measure the diameter of the pool in metres
  2. Half the diameter to give the radius of the pool
  3. Multiply 3.14 x radius x radius x pool depth


A 12' (3.66 m) diameter round above ground pool with a depth of 0.8m

Diameter = 12' x 0.305 = 3.66m

Radius = 3.66 / 2 = 1.83m

Volume = 3.14 x 1.83 x 1.83 x 0.8m = 8.4 m3

The Hot Splash supports pools up to 10m3 so would be ok for this pool

Rectangular Pools

Pool volume = length x width x depth


6m x 4m pool, 0.8 m deep = 6 x 4 x 0.8 = 19.2 m3
