What are the alternatives to gas boilers after UK ban in 2035 and … – inews

Rishi Sunak has announced a major shift in green policies delaying the ban on new petrol and diesel cars and new fossil fuel heating for off-gas-grid homes, but the sale of new gas boilers will still be outlawed from 2035.
In a watering-down of net-zero measures, the block on the sale of petrol and diesel cars moves from 2030 to 2035.
The ban on installing oil, LPG boilers and new coal heating for off-gas-grid homes is delayed until 2035, instead of phasing them out from 2026.
However, the cut-off for the sale of new gas boilers remains at 2035, with exemptions for households who will struggle financially to make the switch.
The Government is also raising the Boiler Upgrade Grant by 50 per cent to £7,500, to help households who want to replace their gas boilers with a low-carbon alternative such as a heat pump.
The Prime Minister said this was a “more pragmatic, proportionate, and realistic approach that eases the burdens on families”.
We take a look what the options are to heat homes if gas boilers are no longer the answer.
The legislation does not mean homeowners must scrap existing gas boilers.
But it will affect the installation of any new boilers in a home from 2035, and what property developers can use in new build homes from the same date.
Heat pumps are likely to become one of the most common ways to heat homes as fossil-fuel boilers are phased out.
The Government had been investigating the possibility of replacing the natural gas network with hydrogen over the coming years to help reach net-zero carbon emissions.
But in July, Grant Shapps, the former energy security secretary, said it was now “unlikely” hydrogen would be used to replace gas-powered boilers because of the need to replace pipework in a switchover.
He told an event at Westminster that he was “a big believer in hydrogen as part of our energy mix in the future” but added: “Hydrogen molecules are very small, you have to replace potentially quite a lot of piping, and of course you’ve got to produce the ‘green’ hydrogen to make the whole thing stack up, the kind of volumes which mean that the transition would be pretty slow.
“So I’m not sure that home heating will be all through hydrogen, it will have a role to play.”
A heat pump uses technology similar to that found in a refrigerator or an air conditioner.
It extracts heat from a source, such as the surrounding air or geothermal energy stored in the ground, increases it to a higher temperature using electricity, and then transfers the heat to where it is needed around a home.
Air-source heat pumps use the heat energy from the air and ground-source heat pumps use geothermal energy from the ground.
Heat batteries are an emerging technology that uses dense natural materials to store heat at high temperatures that can be released slowly over a 24-hour period. They are designed to charge up during off-peak times when electricity tariffs are lower.
The heat battery concept can be used for a heat battery boiler, which would be a direct replacement for a gas boiler.
Electric boilers are also available, but they can cost up to four times more per year to run if using peak-rate electricity and are unable to meet high demands for heating and hot water, so are best suited to smaller homes and flats.
Biomass boilers operate in the same way as conventional boilers but burn biomass (biological material from plant-based organisms such as wood logs, chips or pellets) rather than fossil fuels.
Solar thermal panels absorb heat from the sun during daylight hours and use that energy to heat a water-based central heating system.
Within the panels are tubes of fluid that take in heat from the sun. This energy is then transferred through a heat exchanger before warming the central heating system or water in a cylinder.
