Hydronic heating doesn't blow allergens and contaminants around your house or give them a place to hide in the ductwork. There is no trade-off between healthier air and a more comfortable living space.

The greenest options for eco-heating systems are either water-source heat pumps (which take heat from a large body of water) with a heat battery or a ground source heat pump. Both of these pumps operate with equal efficiency night and day.

This type of system works by using a gas boiler to provide heat in your home through radiators and hot water through taps. There are different kinds of gas boilers for central heating, and you can find out more about these by taking a look at our dedicated boiler guide.

Central heating gets its energy source from a variety of different places including solid fuels (such as wood), water/steam, petroleum and other liquids, electricity, heat pumps, and natural gases. The most common forms of central heating are electricity and gas because they are the easiest to maintain.
