solar panel water heating
Three person system
30 solar evacuated tubes £3,275 (inc VAT)
The single solar panel water heating system containing 30 evacuated tubes
should be sufficient for a three person home
with a southeast to southwest facing roof and average hot water requirements.
- A single solar panel containing 30 high efficiency solar evacuated tubes.
- The panel covers around 3.355 square metres
- Panel dimensions : 1.76 metres (height) * 2.17 metres (width) * 13 cm
- Each double walled evacuated tube is 47mm * 1.5 metres - High efficiency, double insulated, vented solar hot water cylinder (e.g. 162 litres to 210 litres) which will replace your existing hot water cylinder (if you require a less common unvented/mains pressure hot water cylinder, please be aware that these cost around £500 more)
- Copper tubing (with high temperature insulation) required to connect the solar panel to the cylinder.
- A controller that monitors the temperature at three points: the solar panel on the roof, the bottom of your cylinder and the top of your cylinder. The controller automatically switches on the water pump when the water in the panel is about 6 degrees warmer than the bottom of the hot water cylinder.
- Other components required to complete the system, including: an expansion vessel, pressure relief valve, pressure gauge, water pump, non-return valves, stop valves and drain valves.
- Solar antifreeze to ensure the water in the Solar Panel Water Heating system never freezes.
