Evacuated Tube Solar Panel
These top-of-the-range solar panel heat collectors are suitable for heating domestic hot water, swimming pools etc.
Swimming pools are an ideal application for solar water heating, as the temperature required is quite low - under 30°C. Most installers will recommend flat plates to keep the price down - because the amount of panels required is much larger than for heating domestic hot water - however, if you can buy a high efficiency evacuated tube solar panel for the same money - you might as well enjoy solar heated pool water all year round.
A rule of thumb for calculating what you need is to fit the equivalent of 25% of the surface area of your pool based on a South facing location. We have calculated recommended requirements when used in optimum conditions for common pool sizes as shown below.
Specific individual conditions such as the direction your panels face, and the desired pool temperature will also alter performance so take this into consideration in calculations.
Installation is very simple. If you have chlorine you will need to fit a stainless steel heat exchanger (this is because chlorine causes copper to corrode). These are available from pool suppliers (they are needed for conventional heating methods for the same reason). If you dont have chlorine, you can simply put the solar panel in-line with the pool filter, so that the pump directs water through the panel before returning it to the pool. As the panel will NOT radiate heat on cold days, heat losses will be confined to your pipe runs only - so you do not necessarily need a controller, although one can be fitted, to control a 3-way solenoid valve to divert the water through the panel when the panel is hotter than the pool water.
The vacuum tube solar panel has been around for over 10years, and has proved to be reliable and dependable. The vacuum tubes consist of a double wall glass tube (made from strong borosilicate glass ie pyrex) with a space in the centre which contains the heat pipe. The sun's radiation is absorbed by the selective coating on the inner glass surface, but prevented from re-radiating by the silvered innermost lining. This is in effect like a one-way mirror which has been optimised for infra-red radiation. In fact it is very efficient, of the sun light's energy hitting the tube's surface, 93% is absorbed, whereas only 7% is lost through reflection and re-emission. The presence of the vacuum wall prevents any losses by conduction or convection - just like a thermos flask. Because of this, the system will work even in very low temperatures, unlike traditional flat plate collectors. This is why our system can be used to heat up water at the South Pole Antarctic Science Base - where ambient air temperatures can drop below -40°C
Our Evacuated Tube Solar Panels can be supplied in a choice of three sizes, depending on requirements and application needs.
