In conclusion, the most environmentally friendly way to heat your home would be through the use of renewable energy sources such as solar, wind or geothermal energy. Biomass boilers and passive solar home designs are also environmentally friendly and sustainable heating options.

Gas central heating is generally more cost-effective compared to electric heating options. Gas prices tend to be lower, resulting in potential savings on your energy bills. It's worth comparing the energy costs between gas central heating and other options to see which one aligns better with your budget.

Q: How do I know if my heater is electric or gas? A: In order to tell if your heating system is electric or gas, check the front of your heating unit. Through the small window on the front of the heater, you should be able to see a blue flame glowing. Gas heating units use burners to produce heat.

Most of us here in the UK use a mains gas central heating system, sometimes called a 'wet system', to keep ourselves and our homes warm and comfortable. This type of system works by using a gas boiler to provide heat in your home through radiators and hot water through taps.
