As well as being the most popular heating source, gas is also one of the cheapest ways to heat your home and water. A gas boiler will heat up your home quicker than a solid fuel system, and the room temperature is easier to control. As mains gas is piped straight into your home, you don’t have to worry about storage space for wood or coal. With solid fuel you risk no heating at all if your fuel supply is running short.
But as a fossil fuel, gas is not renewable, and it produces more CO2 emissions than biomass energy.
While biomass boilers are the most expensive type of boiler to buy new, the savings in fuel consumption and reduced emissions may make them a better long-term investment.
