Our best selling model, the DuraPro 12 will heat a 8ft square Hot Tub from cold to Hot in around 5 hours. And it only draws 1.5kw per hour.

The Maths!!!

A unit of electric (kwH) is currently 28p.
Your 3kw heater will used 3 x 28p per hour. 84p per hour.
If you spa runs for 20 hours to warm up it will cost you £16.80

The Spa will runs as it needs to during the day and night to recoup lost heat.
Say it runs for 4 hours over a 24 hour period with will cost you £3.36.
So with adding in the cost of running your pumps for heating and usage, you could be up around £5 per day to run the spa!!


The DuraTech will use 1.5kw per hour 42p per hour.
It will get the 8ft square spa hot in 5 hours and cost £2.10
Heat up saving of approx £14.70

The Spa runs for reheat and standard use for the same time as above, cost would be £1.68 per day. But the heat pump heats the water in less than 1/2 the time so this cost should reduce down to 84p per day.

Per 7 days SAVING = £20.16
