Solar swimming pool and hot-tub in Algarve Portugal

Our systems slash your swimming pool energy bills using solar water heating, and you can monitor climatic change and production of energy in real time.

A swimming pool may be a luxury, but it should be a luxury you can easily afford, not something you may be too worried to use because of ever increasing energy costs.

During the last month we have installed the solar heated swimming pool and hot-tub system seen in the accompanying photos. Our aim was to very substantially reduce the electricity bills.

The previous household electricity bills were (2016) 750 euros/month during the summer and 400 euros/month during the winter. Both the pool and hot-tub were not used often as they consumed too much electricity.  About 250 to 300 euros was being spent solely on heating the pool and hot-tub.

The hot tub and swimming pool are now heated by solar thermal panels with two small electric pumps- see graph above for consumption.
The swimming pool & hot tub were a major contributor to the electricity costs in this house, and it can be seen that a huge reduction in energy consumption has been achieved  (now to nearly zero apart from the small wattage of the pumps which you can see in the real time graph).

There is also an irrigation system at the property which runs for two hours in the morning and two in the afternoon, pumping well water. Some of the pumps are rated at 3 to 4 kilowatts; this is also contributing to the high energy bills. We can now analyse future energy needs, as we have eliminated the cost of heating water with electricity and can accurately establish how much solar generated electricity is now needed.

We know what power we need to make the pool 100% solar efficient.

• Swimming pool motor is always running when heat exchange is ongoing this motor draws 6 amps.
• The hot-tub solar pump draws 50 watts when running:
• The solar panel pump (glycol pump) draws about 55 watts  (0.05kw).

So we need to make 1.426kw,  which = 6.2 amps AC at 240v to compensate. This system would be comprised  of six 250 watt solar panels with a micro mains inverter. After installation the pool and the hot-tub will be 100% solar powered with 0 % CO2 emissions. Great for the customer’s pocket and great on the environment.

This post will be updated on a regular basis to show the initial investment necessary, together with bill comparisons to demonstrate the ongoing savings.

Addressing​ ​​your energy consumption & costs makes financial sense. Instead of renting energy you should own it. Once we have tackled the swimming pool heating cost we will then look to reduce the overall electricity bill with solar pv.
