Living somewhere with as changeable and unpredictable weather as the UK, having the right heating for your home is definitely a priority.
Here’s everything you need to know about five different ways.
1. Ground source heat pumps
Heat pumps are one environmentally friendly way to heat your home.
Ground or air source heat pumps are most popular, as water source heat pumps aren't practical unless you have a lake, river or stream in your garden.
Ground source heat pumps extract warmth from the earth and use it to heat your home or hot water.
The (above-ground) pump is connected to a series of pipes (the ground loop) buried in the garden and can be used all year round, although you may need a back-up heating system in winter.
2. Air source heat pumps
Air source heat pumps take heat from the air outside and use it indoors.
They're either air-to-air pumps, which produce warm (and also cool) air and circulate it through fans, or air-to-water pumps, which supply your home's (wet) central heating system.
Air source heat pumps can be less effective when it's colder than -5C, so another form of heating again may be necessary in winter.
If your home is heated by radiators, they won't get as hot with a heat pump as they would with a boiler - you'll need to have them on for longer or replace them with more powerful ones.
The perfect partner for a heat pump is wet underfloor heating because both work at lower temperatures, but this type of underfloor heating isn't particularly easy to retrofit.
4. Biomass boilers
Biomass boilers are another eco heating option, ideal if you want to reduce your carbon dioxide emissions and have access to a regular supply of wood.
These boilers burn wood chips, pellets or logs and can be used for central heating and hot water.
The Energy Saving Trust says that an automatically fed pellet boiler for an average home costs £9,000-£21,000, including installation, so it's not cheap.
However, if you replace an older gas heating system with a biomass system, you could save up to £360 a year, or up to £990 a year compared to an old electric heating system, according to the Trust.
5. Solar panels
If you want to generate your own electricity and have a sunny roof or wall, solar photovoltaic panels are worth considering, but you could fit solar thermal panels, which heat your home's water, instead.
According to the Energy Saving Trust, installing a typical solar water-heating system costs around £3,000-£5,000, but the savings you make will be moderate.
As well as the solar panels, you'll need a boiler or immersion heater to give you additional hot water and sometimes make the water heated by the panels hotter, especially in winter.
You may also have to change your boiler and hot-water cylinder to ones compatible with the panels.
