Biomass Boilers vs Air Source Heat Pumps (and Why Heat Pumps are Better)

We’re all aware that we can’t avoid the impacts of climate change, so how can we help reduce the negative effects we have on the planet?

Two great renewable energy alternatives for fossil fuels are biomass boilers and air source heat pumps. Below, we’ll explore how implementing these into your home or business can help to reduce your negative impact on the environment.

What is an air source heat pump?

Air source heat pumps take energy from the ambient air from outside to help heat and cool your home. Heat pumps can also operate in temperatures as low as -20°, making them suitable for most homes in the UK.

What is a biomass boiler? 

Biomass boilers run on burning wood chips and pellets to bring heat to your home and domestic water system. Using wood in your heating system is more cost effective compared to traditional heating systems, of which is highlighted by data found by the Energy Saving Trust. Findings show that biomass boilers cost 7.9p for every KWh, compared to gas boilers costing 10.3p per KWh.

How efficient are biomass boilers and air source heat pumps?

Most traditional boilers can lose between 25% and 50% of energy produced. Whereas, biomass boilers, when installed properly, have an 80% - 90% efficiency, meaning they lose between 10% and 20% of energy produced. This means that biomass boilers are a more sustainable heating choice when compared to traditional boilers.

Despite this, biomass boilers are no match for air source heat pumps in terms of efficiency, as they produce 4k of energy for every k put in, meaning they have minimal energy waste.

What are the overall lifespans of biomass boilers and air source heat pumps?

Biomass boilers have a lifespan of 8-12 years, as long as you keep up with the required regular maintenance checks. However air source heat pumps can last as long as 15-25 years, if installed and serviced properly. This means that air source heat pumps require less maintenance than traditional boilers and biomass boilers due to them not needing wood replacements, however you should still get them checked regularly.

How much space does each heating system need?

Biomass boilers are quite compact, making it easy for you to fit one in any part of your home, whereas air source heat pumps require space outside. Despite this, air source heat pumps don’t take up too much room and can be installed next to your home for a closer fit.

What impact does air source heat pumps and biomass boilers have on the environment?

Despite the use of wood in biomass boilers not initially seeming environmentally friendly, the wood used is sustainably sourced and grown, meaning they’re regarded as renewable. If biomass boilers are used in large quantities, they can use reclaimed wood and plant materials that would have otherwise gone to waste.

Air Source Heat Pumps are a net zero and renewable energy alternative source to fossil fuels, making them a great alternative energy source for your home. Net zero describes the act of completely removing greenhouse gases produced by human activity, as well as implementing methods to absorb carbon dioxide from the atmosphere.

Which renewable energy source is best?

Air Source Heat Pumps are the better choice if you’re looking to move toward more sustainable energy sources within your home. Heat pumps are a zero carbon and renewable energy alternative to fossil fuels, making them more environmentally friendly than biomass boilers.

Furthermore, air source heat pumps have a longer lifespan than biomass boilers and require less maintenance due to them using air instead of wood chips and pellets that need replacing.
