Heat pumps: is it worth replacing your gas boiler?

Last October, in the run-up to the Cop26 climate change conference, the UK government announced plans to subsidize the roll-out of low-carbon heat pumps to reduce reliance on fossil fuel heating.

As part of a ‘home heating revolution’ in the UK, the government unveiled plans to start phasing out gas boilers by offering £5,000 grants to help 90,000 homes install heat pumps. The guard called.

For 50 years, the gas boiler has been “the backbone of central heating,” he said The times. “But its days are numbered” as new gas-fired boilers will be banned from UK homes by 2035. Although the government is considering a number of green alternatives for heating homes, including using hydrogen boilers, the “most viable” is. The alternative for the majority of households will be electrically operated heat pumps.

Climate change isn’t the only crisis Britain is grappling with – there is Cost of Living Crisis, to. The three-year boiler upgrade program will help “reduce the cost of greener heating systems.” BBC reported. And in his spring declaration Last month, Chancellor Rishi Sunak also announced that households will now pay 0% VAT on energy-saving appliances such as heat pumps solar panels.

What are heat pumps and how do they work?

An electric heat pump works like “an inverted refrigerator, extracting heat from the outside air, the ground or a nearby water source before concentrating the heat and transferring it inside,” explained The Guardian.

Heat pumps are “nothing new”, The Times said, but very few are installed each year – around 27,000. The number of heat pumps installed in UK homes needs to be increased significantly Boris Johnson‘s climate advisors recommend that “there should be 5.5 million heat pumps installed in UK homes by 2030”.

Heat pumps also work when outside temperatures are very low, close to freezing. They’re also “much more efficient than a gas boiler,” being able to “generate about three times the energy they use,” he said i news Side? site.

“Crucially, heat pumps are also clean,” added The Times. Gas-fired boilers produce huge amounts of carbon dioxide: The gas boilers in Britain’s homes “produce twice as much CO2 as the country’s gas-fired power plants”. But if we can ensure that the electricity used to run heat pumps comes from “truly green sources”, then “water is the only by-product” of using a heat pump.

How much does it cost to install a heat pump?

The cost of installing a heat pump can be significant and depends on the type installed and the size of a property BBC called. Installation can also prove to be “difficult and expensive”. For example, you may need to “install larger radiators or dig in floors.”

Heat pump prices are “usually high when you factor in the installation,” he said GreenMatch.de. The typical price range for a complete installation is “between £8,000 and £45,000, taking into account running costs”. The cost of an air to water heat pump ranges from £7,000 to £18,000, while ground source heat pumps can cost up to £45,000. “The running costs of a heat pump depend on your household, its insulation properties and size.”

What subsidies are there and who is eligible?

Government grants are provided through the Boiler Upgrade Scheme to encourage property owners to install low-carbon heating systems such as heat pumps, according to the Department for Business, Energy and Industrial Strategy explained. The scheme is open to private and small non-residential buildings in England and Wales and will run from 2022 to 2025. “These grants will help owners overcome the upfront costs of low-carbon heating technologies.”

Beginning April 1, when the installation and system set-up of a low-carbon heating system is complete, you are eligible for assistance under the program. From April 11th installers will be able to open an account for the program with the administrator Ofgem and from May 23rd the program will be open for grant applications and payments.

Permissions include:

  • £5,000 off the cost and installation of an air source heat pump
  • £5,000 rebate on the cost and installation of a biomass boiler
  • £6,000 off the cost and installation of a geothermal heat pump

What advantages do heat pumps offer?

Heat pumps are “typically three times more efficient than gas boilers, but they require electricity to run and electricity prices tend to be more expensive than gas,” the BBC said. In view of the currently high gas prices, “heat pumps could be even cheaper”. The government has said it will look at ways to ensure heat pumps are “no more expensive to run than a gas boiler in the long run”.

According to GreenMatch.co.uk there are seven key benefits of heat pumps. These are:

  • Lower running costs
  • Less maintenance
  • Better security
  • Reduces carbon emissions
  • Provides cooling
  • Long life span
  • Eligible for the RHI program

What are the disadvantages?

Although the government is providing £450m for the new subsidies, these will only cover the cost of replacing around 90,000 boilers. Houses also need to be well insulated to stay warm when using a heat pump, which not only increases costs but the “high level of insulation required” is not “always possible in older solid walled houses which is common across the UK”. . , said the BBC.

Installing a heat pump “may not be the best option for your home and the cost could be prohibitive,” he said The Telegraph. “Although technology is evolving and expected to improve significantly and reduce costs in the coming years, heat pumps are currently slower than traditional boilers at heating cold homes.”

Space could also be an issue, as you “need a spot outside of your home where a unit can be mounted on a wall or placed on the floor,” he said Energy Confidence. “There needs to be some space around it to allow for good airflow.”

According to GreenMatch.co.uk, seven main disadvantages of heat pumps are:

  • High acquisition costs
  • Difficult to install
  • Questionable sustainability
  • Requires significant work
  • problems in cold weather
  • Not quite carbon neutral
  • Building permit required

Kevin McCloud, host of the TV show Great designsHe considers spending millions on heat pumps to be a “classic pitfall”. The Telegraph reported. In an interview with the newspaper, McCloud said heat pumps are “wonderful machines” and that he was a “big fan” saying the UK should focus on insulation, ventilation and shutters instead.
