Solar heating (EPDM solar collectors)

The EPDM solar heating system consists of a long flexible rubber mat connected to ASA collectors. Our EPDM mats are pre-assembled in units of 33 cm wide and from 2 to 6 metres long as standard.

The units can be clicked together to form one large solar collector. Customised EPDM is also possible. Our elastic EPDM rubber is UV, ozone and frost resistant and lasts 5 times longer than cheaper materials on the market.

Energy efficiency and payback period

Solar heating: What is it and how does it work?

ZERO ENERGY +6°C BATH TEMPERATURE

To heat your pool, you can use a heat pump, solar collectors or a combination of both.

Solar heat has the great advantage that it can work via the filter pump and therefore does not consume any energy. The system is simple: the pool water is circulated through thin black tubes, which heat the water when the sun shines.

The sun's rays provide 800W of energy per m², which applies everywhere on earth. In the United Kingdom, we need between +- 30 kW to heat a 50 m³ pool with solar heating, so between 25 and 35 m² of solar heating. This applies to all types of heating: heating with and without bubble or protective glass. Do not let anyone convince you otherwise, because you will be disappointed: you need this surface area for all types of solar heating.

Why EPDM?

EPDM (Ethylene Propylene Diene Monomer)

is water-resistant,
has high elasticity
can be used at temperatures between -35°C and 120°C.
is resistant to weather, ozone and UV radiation
has excellent resistance to salts, bases and acids.&In short, it is the most durable material for leak-free heating of your pool. It lasts up to 5 times longer than cheaper materials on the market.

Dimensions of solar collectors and installation

The heating mats are pre-assembled and click together.
The standard lengths available are 2, 3, 4, 5 and 6 metres. We also produce custom-made sensors. The sensors have 32, 38 and 50 mm connections for gluing. Installation is often carried out on the roof of a garden shed or carport. We recommend that you first install a concrete grid and then attach the solar collectors to the grid using our polyester tapes. The ideal location is at a 30° angle to the south. Placing the heating horizontally results in a 10% loss of capacity.

Connection and control of solar heating

Combination of heat pump and solar collector

Control is provided by a 3-way valve, either manually or automatically.

Thanks to the Benisol control box, the automatic valve directs the water to the solar collectors as soon as the temperature on top of the heater is higher than the water temperature. At a temperature of 32 °C (adjustable), the valve directs the water straight to the pool and thus stops heating. We have manual, automatic and Wi-Fi 3-way valves. All valves are 100% pre-assembled.

In a combined heat pump and solar collector installation, the water is first passed through the solar collector. The heat pump is set to 2-4°C lower than normal (setpoint 24-26°C). The reduction in energy costs will pay for your solar installation in 2-3 years. The service life of solar collectors is 10-20 years.
