Your energy consumption for heating could be lowered by up to 75% with the use of a geothermal heat pump. Ground source heat pumps are stored in the ground. During the summer solar heat is stored in the soil. It is then either absorbed as insulation or as heat from rain and the air. The highest yield can be obtained from the soil with high water content. The heat is then extracted from the soil by means of plastic tubing buried in the soil
If you were looking to install an air heating system, it could lead to your energy consumption for heating being reduced by up to 50% in comparison to conventional heating systems. Air heat pumps utilise the heat energy of the outside air. The heat pumps are designed for outside placement and transform an existing radiator system into an excellent, complete heating system.
Rainwater is a precious resource. Unpredictable rainfall in the UK due to climate change has seen large flooding during winter and drought during the summer months. Harvesting rainwater can help to overcome both problems. It can provide a constant supply of water during dry conditions and divert excess rainfall, relieving the pressure on local drains that leads to flooding. Other benefits to harvesting water are reduction in mains water consumption and in mains water bills, together with a reduction in your carbon footprint.
A solar thermal system can deliver up to 70% of your hot water requirements, based on government figures. Even on a cloudy day and temperatures as low as -28c, your solar panel is effective. Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a backup to heat the water further to reach the temperature you want. Larger solar panels can also be arranged to provide some contribution to heating your home as well.
Log stoves are more fuel efficient than open fires and burn much more cleanly, so if you want to heat your home with wood fuel on a limited budget this may be the best value option. Log fired boiler systems are the next step up from log stoves and can run both heating and hot water. Pellets stoves and boilers can be the more convenient option as are often smaller in size than word burning stoves and boilers. Also, compared with logs and chips, pellets have a high energy density which means that less storage space is required than other types of biomass fuel like logs.
Biomass is a renewable, low carbon fuel that is already widely available. Domestic applications focus upon the generation of heat and hot water using either pellets of dry wood (<12% moisture content) with the added bonus of renewable heat incentive (RHI) payments that make this installation very attractive indeed..
