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

Maximum for Hot Splash = 10m3 so this would be too large - look at our SunSpring heat pumps

Typical Pool Sizes and Volumes

8' x 30" Intex above Ground pool = 3.6 m3 - Hot Splash OK !

10' x 30" Intex above Ground pool = 5.5m3 - Hot Splash OK !

12' x 36" Intex above Ground pool = 9.6 m3 - Hot Splash OK !

Need a Larger Size

If your above ground pool is larger than 10m3, the please look at our SunSpring range of pool heat pumps as these will cover pools that have from 12m3 of water up to 45m3 of water.


Installation is very easy and straightforward. 

The hot splash is connected to your existing pool pipework

It uses the existing pool circulation pump to pump the pool water through it.

Please see the user manual below for more information on how to install your Hot Splash heat pump

Using the Hot Splash heat pump to heat your pool rather than an electric heater will save you money on running costs

The Hot Splash only uses 0.56kw of electricity to produce 3.35kw of pool heat.

If you compare this with an electric pool heater, a 3.35kw electric pool heater would use 3.35kw of electricity

The Hot Splash therefore is only less than 1/4 the running cost of an electric pool heater - saving you money!

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

Customer Feedback

"Works a treat. Best investment ever. Gone are the days of jumping into a cold pool. I have a 10ft round pool and it heats it up to my set temp which is 28 deg c. Possibly could get pool warmer but 28 deg is warm enough for me." xcalibur76 27 Jun, 2016
