Solar cylinders are the components involved when converting solar power into energy. They are found in the between the solar panels and the boiler. It is made up of efficient twin coils to heat up water for use.
How it works
Solar cylinders work through a highly efficient copper solar coil, which is fitted into the base of the cylinder. Water which is heated by the sun in the Solar Panels is pumped through this copper coil and it indirectly transfers heat into the domestic hot water. The water temperature can be raised if required by the normal method of Boiler or Immersion Heater.
There are different types of solar cylinders available:
- Un-vented cylinders, used for a flexible mains pressure hot water system for distribution to multiple points throughout the building.
- Vented cylinders which offer a hot water storage solution for any pressure requirement in the UK.
- Twin coil cylinders- used with solar energy systems and heat pumps.
If the volume of stored water is not hot enough, can be fed direct to the tap (i.e. 60°C plus). When the water is pre-heated but not up to 60°C the solar valve diverts it via the combination boiler where it is heated up to the required temperature, but at a reduced gas rate.
Benefits
- Solar cylinders reduce carbon dioxide emissions as the hot water supplied by a sustainable natural resource.
- The system offers many ways of saving energy and reducing heating bills as no gas is used to heat water, and if water temperatures do need to be raised, minimal gas is used.
- The system works with a combination boiler so that hot water is not stored unnecessarily and is always available.
- Sunlight is free so after initial costs electricity bills would be greatly reduced.
- Minimal maintenance is required.
Installation and where it can be used
Solar cylinders can be installed where solar panels are in use. They are easy to install and are to be stored in their original packaging in an upright position, away from damp conditions.
