Solar thermal power (electricity) generation systems collect and concentrate sunlight to produce the high temperature heat needed to generate electricity. All solar thermal power systems have solar energy collectors with two main components: reflectors (mirrors) that capture and focus sunlight onto a receiver. In most types of systems, a heat-transfer fluid is heated and circulated in the receiver and used to produce steam. The steam is converted into mechanical energy in a turbine, which powers a generator to produce electricity. Solar thermal power systems have tracking systems that keep sunlight focused onto the receiver throughout the day as the sun changes position in the sky.
Solar thermal power systems may also have a thermal energy storage system component that allows the solar collector system to heat an energy storage system during the day, and the heat from the storage system is used to produce electricity in the evening or during cloudy weather. Solar thermal power plants may also be hybrid systems that use other fuels (usually natural gas) to supplement energy from the sun during periods of low solar radiation.
Biomass boilers tend to be larger than the gas or oil equivalent. They are generally more suitable for people not connected to mains gas who have some space for fuel storage. You will need about 6-7 cubic metres of space near where the boiler is sited to store the fuel (for an average size house). To do a detailed initial assessment of whether or not it's appropriate, you can download the Carbon Trust's publication Biomass heating: a practical guide for potential users.
Ideally the fuel storage area will be under cover, as it is important to keep fuel dry. High moisture content in the fuel will reduce the efficiency with which it burns and if wood pellets get wet they turn to unusable mush.
Your property also needs to be accessible for a delivery lorry. Wood pellets can be delivered loose and blown into a hopper or in bags on a pallet.
The boiler will need a flue designed for wood fuel (existing chimneys can be lined). The installation must comply with all relevant building regulations, particularly if you live in smokeless zone. If you live in a listed building or a conservation area you will need to check with your local planning authority before fitting a new flue.
It’s important to check that the boiler will work with your existing plumbing, or whether it needs to be altered. Also find out how easy it will be to get the boiler serviced regularly and whether there are local plumbers or engineers who know how to work with it.
Also, find out if there is at least one, or preferably a choice of, local fuel suppliers, as the cost of fuel varies according to the distance the supplier has to travel. Not all suppliers offer all types of fuel. The lowest maintenance way is in a tanker to a hopper. A pallet full of bags will involve more work feeding the boiler as lifting and emptying the bags is a physical job. The National Energy Foundation has more information on buying and using wood fuel and an up to date list of local wood fuel equipment and fuel suppliers at Log Pile.
Wood pellet boilers will need an annual service.
Air source heat pump
An air source heat pump is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump needs electricity to run, but it should use less electrical energy than the heat it produces. Take a look at our graphic below for a visual representation of how an air source heat pump functions. Many air source heat pumps are eligible for payment through the Renewable Heat Incentive, a government scheme that provides payments to homeowners who generate their own heat.
