There are a number of alternative energy supplies that are becoming increasingly popular. They can reduce carbon dioxide emissions, save you money on your fuel bills and our dependency on fossil fuels. Renewable energy sources such as the sun, wind and rain will never run out unlike fossil fuels.
There are two types of heat pumps:
Ground Source heat pumps circulate a mix of water and anti-freeze around pipes buried in your garden. The liquid absorbs heat from the ground which stays at a constant temperature even in winter. Used for heating radiators, underfloor heating systems and even hot water.
Air Source heat pumps extract heat from the air and uses it to either warm water, especially suitable for under floor heating systems, or to produce warm air which is circulated by fans to heat your home.
- More efficient method of heating. Reduces C02 emissions from 1.2 to 7.5 tonnes per year, depending on which fuel is replaced
- Save from £350 to £1000 a year on your heating bills depending on which fuel is replaced
- Saves space in the home
Air source heat pumps are easier and cheaper to install but not as effective as ground source heat pumps
Solar Water Heating
Solar water heating systems use heat from the sun to work alongside your conventional water heater. Solar water heating can provide you with about a third of your hot water needs. The average domestic system reduces carbon dioxide by around 325kg per year when installed in a gas heated property. Higher savings can be achieved in oil or electrcially heated homes.
Wood Fuelled Heating
Standalone stoves that heat a single room can be fitted with a back boiler to provide hot water too. A wood burning boiler can be connected to a central heating and hot water system.
Wood fuelled heating is carbon neutral, releasing the same amount of C02 as was absorbed while the wood was growing.
- Save on your fuel bills, from £180-3350 per year
- Saves on landfill and waste management
Rainwater Harvesting is a means by which rain is stored in a tank until required for use. When needed, the water is then pumped to the point of use, thus replacing a large proportion of the water that would normally be provided by the mains supply, thereby greatly reducing overall water supply costs.
It should be noted that rainwater is not suitable for drinking without treatment, but can be used for many other purposes throughout the home such as bathing, showering, flushing toilets and washing laundry.
