What will be the replacement for gas boilers?
According to the International Energy Agency (IEA), GAS boilers should no longer be marketed after 2025 if net-zero emissions objectives are to be attained by 2050. But what will replace them?
Gas boilers emit greenhouse gases, which contribute to global warming. Other boiling units and systems must be adopted instead to help the world achieve its net-zero goal. There are a variety of alternative ways to move toward clean home heating.
According to the International Energy Agency, the government will need to abolish fossil fuel boilers by 2025 in order to fulfill its net-zero emissions objective by the middle of the century.
The move is one of 400 measures advocated by the government in a special study on the path to net-zero energy.
By 2035, new petrol and diesel cars would no longer be sold anywhere on the planet.
However, due to criticism from the public over the high expense of sustainable alternatives to gas boilers, Britons may be allowed an extra five years to replace their gas boilers.
From 2035, the installation of new gas boilers in owner-occupied residences will be prohibited.
Natural gas boilers are used in 85 percent of houses, and domestic heating accounts for 14 percent of the UK’s carbon emissions.
Government ministers have warned that replacing gas boilers with more efficient and ecologically friendly alternatives might cost £400 billion.
In the UK, an estimated 23 million homes need to have their systems replaced.
Alternatives to gas boilers include electric heat pumps, air source heat pumps, and ground source heat pumps.
These can cost anywhere between £4,000 and £14,000 to buy and install, which is much more than the typical cost of a gas boiler, which is £1,000.
Heat pumps are currently roughly £400 per year more expensive to run than boilers since electricity is more expensive than natural gas.
Solar water heating systems can also be a good alternative to a gas heater, although they are more expensive.
These boiling devices typically cost around £5,000 and come with a storage battery to heat water on gloomy days and overnight.
Another option is hydrogen-ready boilers, with the government looking at delivering a hydrogen mixture via the existing gas infrastructure.
However, these can be quite costly, with boilers capable of handling only gas mixtures containing 20% hydrogen costing £1,200 each.
