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

5. Easy to Operate

The SunSpring swimming pool heat pumps have a user friendly colour digital display panel

The display panel has three buttons for easy operation

The display has a unique water flow indicator scale to instantly show the water flow rate through the heat pump so that you can be sure that it is sufficient.

The display shows the current pool temperature and the set temperature.

6. Fitted with UK or Euro Plug

All of our Sunspring heat pumps are fitted with a UK 3-pin mains plug/RCD.

We can also supply them with a 2-pin euro plug on request

Comes with UK 3-pin plug/RCD (shown above) Optional Euro 2-pin plug/RCD shown above (available on request)

If your outdoor socket is already protected by an RCD, then if you prefer, the fitted RCD/Plug can be unwired and replaced with a standard UK 13A plug.

Note: The Sunspring heat pumps require a 220v or 240v, 50hz power supply and therefore are not suitable for use in the USA/Canada (which uses a 110v, 60hz power supply)

7. Hose and Solid Pipe Connections Included

The SunSpring models come with hose tails to take both 1.25″ (32mm) and 1.5″ (38mm) flexible hoses.

They also include the connectors for 50mm and 1.5″ solid pipework

9.  Easy Installation

The SunSpring Swimming Pool Heat Pumps are designed for quick and easy setup and operation.

They come complete with UK (or Euro), RCD/plug and flexible hose connections to suit most above ground pools

Note: The SunSpring05, SunSpring07 and SunSpring10 come with a pre-fitted UK plug/RCD (or Euro plug/RCD on request). 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.
