Gas boilers give off emissions which contribute to overheating the planet. Instead, other boiling units and systems need to be used to help the world hit its net-zero target. There are several other options to make steps towards clean home heating.

The IEA has said the country needs to ban fossil fuel boilers from 2025 to meet its net-zero emissions target by the middle of this century.

The move is just one of 400 steps on the road to net-zero which have been proposed by the agency in a special report.

The sale of new petrol and diesel cars around the world would end by 2035.

Britons could be given five additional years to replace their gas boilers however, as the Government bows to pressure over the high cost of sustainable alternatives to gas boilers.

People will face a ban on the installment of new gas boilers in owner-occupied homes from 2035.

In total, 85 percent of homes use natural gas boilers – domestic heating currently accounts for 14 percent of the UK’s carbon emissions.

Government Ministers have warned Britons could face a £400 billion bill to change their gas boilers to more efficient and environmentally-friendly alternatives.

Systems need to be replaced in an estimated 23 million homes in the UK.

But what will replace gas boilers?

Electric heat pumps, air source and ground source are seen as the most effective alternatives to gas boilers.

These can cost anywhere from £4,000 to £14,000 to purchase and install – which is significantly more than the £1,000 which is the average cost of a gas boiler.

Electricity costs more than natural gas – heat pumps are currently around £400 per year more expensive to run than boilers.

Solar water heating systems can also be an effective substitute for a gas boiler, but these can be costly.

These types of boiling units tend to cost around £5,000 and include a storage battery necessary to heat water on overcast days and overnight.

Hydrogen-ready boilers are another possible alternative, with the Government exploring the delivery of a hydrogen mixture over the existing gas grid.

However, these can be very expensive, costing £1,200 each for boilers equipped to handle only gas mixtures with 20 percent hydrogen.

The Government is said to be considering giving low-income households grants to cover the entire cost of switching to low-carbon heating technologies.

The Government’s recent Green Homes Grant was designed to help people install heat pumps.

However, the grant failed and was scrapped after six months much to the dismay of MPs who want a multi-decade scheme to help people heat their homes cleanly.

Heat pumps are subsidised under a scheme called the Domestic Renewable Heat Incentive.
