Gas Boilers Vs Heat Pump Technology

Approximately 80% of UK buildings are currently heated by gas, although this is already starting to change as the UK continues on the path toward net zero. This shift has seen heat pumps become an increasingly common alternative to gas boilers due to their lower running costs and significantly reduced impact on the environment, but how do the two compare?

Heating provided by gas is slowly becoming a thing of the past with the UK’s pledge to become net zero by 2050, particularly with the significant benefits to utilising alternatives that are both cleaner to run and can operate on renewable energy. Heat pump technology used in air conditioning is at the forefront of this change and not only provides cost-effective heating solutions, but it can also offer the benefit of cooling during the increasingly frequent heatwaves we experience in the UK.

The experts at MAC can provide you with the solutions you need and any information regarding whether heat pumps are best suited to you.

Can I still buy a gas boiler?

As of right now, you can still buy a gas boiler for your home if your existing one needs replacing. However, from 2025 the UK government is bringing in legislation where new build homes will no longer be installed with gas boilers.

Fortunately, this doesn’t mean you'll need to find a gas boiler replacement before 2025, although it does mean all new housing will be installed with an alternative heating system such as heat pump technology or boilers that run on alternate power sources like as electricity or biomass.

The UK government have advised they will not completely ban the sale of new and replacement natural gas boilers in existing housing until 2035.

Heat Pumps Vs Gas Boilers:

Which is more efficient?

Heat pumps use a compressor to move heat from one location to another by circulating refrigerant enclosed in pipework, allowing it to extract heat from an outside source. This outdoor heat can originate from a number of sources including the ground, although specifically in the case of the technology used in air conditioning, the heat is drawn from the air itself.

Over the years, boilers that provide heating have become more efficient than ever but still require fuel in order to operate. Heat pumps rely on electricity to run and while gas is generally cheaper than electricity, the efficiency ratings of heat pumps are much higher than those of gas boilers. Modern gas boilers less than 10 years old typically have an efficiency rating of around 90-94%, which means for every pound spent, up to ten pence is wasted.

In direct comparison, the air conditioners supplied and installed by MAC utilise heat pump technology to achieve an efficiency rating of 300-400%, meaning for every kilowatt of electricity used, three to four times more energy is given. Heat pump technology is re-establishing the benchmark for energy efficiency, providing a more efficient and eco-friendly alternative to traditional and harmful boilers utilising fossil fuels.

Are Heat Pumps More Expensive Than Gas Boilers?

Purchasing a gas boiler is cheaper than the initial investment of a heat pump system, although the difference in their efficiency does generate a significant saving in a relatively short period of time, as heat pumps offer both a higher efficiency rating and low maintenance costs in comparison. A new gas boiler installation usually falls within the range of about £3000-£4000 and can usually be completed within two days, whereas a complete heat pump system will likely be closer to £15000 and take up to five days, but that's where air conditioning comes in.

Air conditioners use air source heat pump technology to provide all the benefits of a heat pump system in terms of efficiency but at a much lower investment starting at £1800 with comparatively quick and easy installation that can be completed in a little as one day.

MAC is here to help with all your questions and considerations about heat pump technology so you can find the best solution to suit your needs. Our expert team of qualified engineers ensure not only the highest standards, but a wealth experience to ensure you get the very best out of your investment, giving you peace of mind you've made a sound choice for your energy needs.

Heat Pumps Vs Gas Boilers:

Which Heating Solution is Cheaper To Run?

It is a fact that electricity is more expensive than gas, making it seem as if a gas boiler is a more financially viable option compared to the electrically powered heat pump. Although the gap between the cost of electricity and gas is closing with each passing month. Fortunately, the efficiency ratings for heat pumps running on electricity mean you will end up paying less in the long term than you would with a gas boiler.

For direct comparison, the typical running costs to heat an average 3 bed house with an air conditioner using heat pump technology is around 48p per hour. Whereas the typical running costs to heat an average 3 bed house with a top of the range gas boiler is closer to £2 per hour.

In addition, boilers utilising gas or any other kind of fuel require yearly maintenance to function as effectively as possible and this also applies to heat pumps. Systems that use heat pump technology like air conditioning also need yearly maintenance to maximise their longevity, although this is relatively inexpensive with the newer technology becoming more commonplace and accessible. Unfortunately this is not quite the case with gas boilers, as both repair and maintenance costs will start to increase exponentially once their installations across the UK begin scaling back from 2025.

When it comes to maintenance costs, MAC can also offer you peace of mind with detailed maintenance plans at competitive rates, ensuring you make the most of your investment in heat pump technology so it lasts for years to come.
