The 20 tube double-walled tube collector (47mm tubes) is 1760x1500x130mm (LxWxH)
The 30 tube double-walled tube collector (47mm tubes) is 1760x2170x130mm (LxWxH)
The 20 tube double-walled tube collector (58mm tubes) is 1900x1660x130mm (LxWxH)
The 30 tube double-walled tube collector (58mm tubes) is 1900x 2406 x130mm (LxWxH)
The 10 tube single-walled tube collector (70mm tubes) is 1760x1000x130mm (LxWxH)
The 20 tube single-walled tube collector (70mm tubes) is 1760x 1950 x130mm (LxWxH)

What weight are the collectors?
The 20tube 47mm panel is 48kg, the others are more or less proportional to this weight

Are The Tubes Fragile?
Are they tough enough to survive impact from falling hailstones and animals? The tubes are made from borosilicate glass, which is very tough (also known as pyrex). The tubes are designed to withstand hailstones up to 25mm - so they are unlikely to be broken, unless dropped onto a solid floor prior to installation. Impact from falling animals is not normally considered in the design of the tubes(!)

How hot will the water get?
This depends on the size of the cylinder you chose, and the amount of water you use. A smaller cylinder will be heated to higher temperatures, whereas a larger cylinder will heat more water, but not to the same extent. Systems are generally designed to heat water to 65C or so, although during the winter, it may be necessary to 'top-up' the heat on less sunny days. Large arrays, running high temperature solar antifreeze at high pressures can be designed to achieve temperatures of 170C or more!

Does the roof need to be strengthened at all?
The solar panel in operation weighs around 50kg - this is really not much weight for a roof, when you consider the weight of the tiles or slates. Generally there is no requirement to strengthen a house roof prior to mounting the solar panel, except if you are fitting a panel to a very old roof, which has sagging and decaying timbers.

Are the panels guaranteed?
Yes, normally the panels come with a 24month guarantee, although, with no moving parts the panels are extremely long-lived, probably in excess of 25years. An additional 10year+ warranty can be provided if required on the complete installation, for an additional fee.

How much maintenance do the systems require?
Very little maintenance is required for solar water heating systems. You should occasionally check the system pressure, to make sure there has been no water loss, and to check for any air in the system.

Do I need planning permission?
No you do not need planning permission, unless you are in a conservation area or you are installing on a listed building.

How many panels/tubes do I require to meet my household needs?
This is a difficult question to answer as it depends on your water usage. Contact us and we can talk you through your installation and calculate the appropriate hot water storage volume and suitable panels.

How many panels do I need to heat my pool??
It depends what area of pool you need to heat, how well insulated it is, whether it has a pool cover, if it is above/below ground, how many weeks of the year you need to use it etc. However, we recommend that you start with solar panels equivalent to 25% of the pool area, but you can increase this up to 35% if more heat is required. As the panels are modular, it is easy to upgrade the panels at a later date if required. It is strongly recommended that you use a pool cover when the pool is not in use, as it dramatically reduces heat loss through evaporation.
