6. Built in Water Flow Switch

The Thermotec Penguin has a built in water flow switch.

The water flow switch automatically shuts down the heat pump when there is no (or insufficient) water flow and re-starts it when sufficient water flow is resumed.

This allows the Thermotec Penguin to be used in conjunction with a time clock on the pool circulation pump.

When the circulation pump turns off, the Thermotec Penguin will shut down and when the circulation pump re-starts, the Thermotec Penguin will also re-start.


(Note: the Penguin should be removed from the plywood base when in use as this is only for transport purposes)

7.  What size Thermotec Penguin 4kw heat pump do I require for my pool?

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 Penguin supports pools up to 10m3 so would be ok for this pool

Note: These sizings assume that the pool will be covered with a solar cover when not in use. All pools should have solar covers.

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 Penguin= 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 – Thermotec Penguin OK !

10′ x 30″ Intex above Ground pool = 5.5m3 – Thermotec Penguin OK !

12′ x 36″ Intex above Ground pool = 9.6 m3 – Thermotec Penguin OK !

8. Additional Fittings

9. Specifications of the Thermotec Penguin 4kw


Please also see the Specifications tab at the top of the page

10. Installation of the Thermotec Penguin 4kw


Installation is very easy and straightforward.

The Thermotec Penguin 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 under the product literature tab at the top of the page, for more information on how to install your Thermotec Penguin heat pump

8. Savings

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

The Thermotec Penguin only uses 0.78kw of electricity to produce 3kw of pool heat.

If you compare this with an electric pool heater, a 3kw electric pool heater would use 3kw of electricity

The Thermotec Penguin therefore is only less than 1/4 the running cost of an electric pool heater – saving you money!

9. 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
