Twin Coil Solar Cylinders
The Newark Copper Cylinder Co Ltd has manufactured solar cylinders for approximately 20 years. Over this time we have developed a wide range of solar cylinders, with different combinations of features including:
- Single coil Solar cylinders
- Twin Coil Solar Cylinders
- Triple Coil Solar cylinders
- Vented twin coil or triple coil solar cylinders
- Unvented twin coil or triple coil solar cylinders
- Vertical solar cylinders
- Horizontal solar cylinders
for solar panel and manufactures and installers alike.
Our twin coil and triple coil solar cylinders are specifically designed to work in conjunction with the domestic heating system. Our solar cylinders are manufactured with either twin or triple independent coils. One or two coils are designed to transfer heat from an independent heating source, (eg. transferring heat from a central heating boiler or solid fuel boiler to the water in the solar cylinder) and the solar coil, which is manufactured from high efficiency finned tube with a large surface area, to transfer heat from the solar panels into the solar hot water cylinder.
The boiler coil which (if fitted) is manufactured to BS 1566, can also be supplied as high recovery to reduce boiler cycling. Cylinder connection sizes can be specified as 22mm or 28mm compression. The high efficiency solar coil is fitted with 15mm or 22mm compression and with all connections protruding beyond the insulation. This makes our twin or triple coil solar cylinder one of the most efficient manufactured in the UK.
The cylinders are available in three grades - Grade 1, Grade 2, & Grade 3, with grade 3 generally being selected for normal domestic use. Grades 1 & 2 are made from heavier material and are most often used where there is a greater working head of water or where improved durability is required.
Alternative heights and diameters are also available in our range of solar cylinders where space and water volumes are at a premium. In general, solar cylinders are sized to suit the number of house holders and the solar thermal panel surface area.
| Diameter - metric | Diameter - imperial |
|---|---|
| 300mm | 12" |
| 350mm | 14" |
| 375mm | 15" |
| 400mm | 16" |
| 450mm | 18" |
| 500mm | 20" |
| 600mm | 24" |
Accredited with Clearskies, the Low Carbon Buildings program, and member of the Solar Trade Association we at Newark Copper Cylinder Co Ltd are more than happy to speak to, and work with other solar companies regarding the development and supply of alternative specification solar cylinders.
