In an attempt to reduce carbon emissions, the U.K. government has announced a ban on gas boilers. This is causing consternation as many households in the U.K. rely on gas boilers to supply central heating for their homes. The U.K. wants to hit a net-zero target by 2050, and banning the installation of gas boilers is one way to help reach this target.
When is installation being banned?
In 2021, the government’s Heat and Buildings Strategy outlined the changes that need to take place to make U.K. buildings more environmentally friendly. When it comes to banning gas boilers, the strategy takes place in two stages.
From 2025 gas boilers are banned from installation in all new builds. Newly built homes will not connect to a gas network and will have to install low carbon heating measures. The option of using modern electric radiators from companies like Best Electric Radiators is likely to be popular. Not only are modern electric radiators aesthetically pleasing to look at, but they offer great energy efficiency and cost savings and require little maintenance.
In addition to this 2025 goal, the aim is to phase out the installation of gas boilers altogether beyond 2035. This means that if a gas boiler gives trouble after 2035, homeowners will have to install a low-carbon alternative rather than a new gas boiler.
Why is the ban happening?
Many greenhouse gasses come from domestic energy use and mostly from gas boilers. Continuing to use them is destructive to the planet. To become net zero by 2050, the U.K. has to drastically reduce the use of gas boilers as one of several steps to reach its goal. It starts with banning gas boiler installation in new builds but has to eventually result in the discontinuation of the sale of gas boilers. The International Energy Agency has emphasized that it doesn’t want any new gas boilers to be sold after 2025.
According to NHF research, 25 million homes produce 58.5 million tonnes of CO2 every year. This is equal to the emissions of 28 million cars. There is obviously a need for serious measures to reduce household greenhouse gas emissions.
Could the ban be delayed?
It is still possible that the start of the ban on gas boiler installation could be extended due to the considerable challenge of millions of existing homes making the switch from gas boilers to alternative energy sources. The government has received some backlash over its plans due to the high cost of some low carbon alternatives. They are simply not affordable for all households. However, climate experts warn that any delay could prevent the U.K. from achieving its net-zero targets.
Boiler Upgrade Scheme
As part of a boiler upgrade scheme, the U.K. government will give households a £500 grant if they switch to low carbon technologies, such as heat pumps. The scheme starts running in April 2022 and will continue for three years. The government has set aside £450 million for this scheme.
What will replace gas boilers?
There are a number of green alternative heating systems that produce much lower carbon emissions than gas boilers. Although replacing a gas boiler with low carbon technology can save on annual household heating bills, most homeowners still need an incentive to install them due to high installation costs.
Heat pumps
Homeowners can consider installing air source or ground source heat pumps. Air source heat pumps are less expensive to install than ground source heat pumps and have low running and maintenance costs.
Ground source heat pumps are efficient but costly to install. They are best suited for newly-built homes, which offer scope for planning their installation, which can take significant space.
Biomass boilers
A biomass boiler may be a better option where properties are not really suited to installing a heat pump. A biomass boiler uses natural materials, such as wood pellets, as a renewable heat source. The fuel costs and environmental impact are much lower than gas boilers.
Future heating of homes
In the future, homes in the U.K. will use heat pumps and other low-carbon systems rather than gas boilers. With new government initiatives, like the Boiler Upgrade Scheme, more people will be able to afford low carbon alternatives.
