Air Source Heat Pumps

OHM Energy Sussex

What Are Air Source Heat Pumps?

Air source heat pumps (ASHPs) are an innovative and sustainable heating technology that works somewhat like a refrigerator but in reverse. Where a refrigerator works by removing heat from inside itself, an air source heat pump takes heat from the outside air and upgrades it to heat homes and hot water, even when temperatures are as low as -25°C. This technology suits Sussex’s climate, offering an energy-efficient solution to heating needs throughout the year.

Air-source heat pumps are often considered brand-new technology, but any home with a refrigerator already utilises a similar mechanism, as both systems are essentially heat pumps. Thus, ASHPs are a familiar technology in a new application.

What makes Sussex such a great location for Air Source Heat Pumps?

Sussex is particularly well-suited for adopting air source heat pump (ASHP) technology, thanks to its climate, the characteristics of its rural areas, and the potential to integrate with solar power.

Climate

Sussex enjoys a temperate climate with mild winters compared to many other regions in the UK. This is advantageous for ASHPs, which take latent heat from environmental air. The mild temperatures in Sussex ensure that ASHPs are cost effective further benefitting the homeowner.

Rural Areas with Oil Dependency

A significant portion of Sussex is rural and not connected to the national gas grid, which means that many residents are forced to rely on oil for heating. This reliance is getting increasingly costly, not to mention being bad for the environment. ASHPs provide a sustainable alternative, offering rural homeowners a more environmentally friendly heating solution that reduces carbon emissions. And you’ll no longer have to have an oil delivery every 6 months!

Solar Integration Potential

Depending on who you talk to, Eastbourne, Hastings and Bognor Regis all claim to be the sunniest place in the UK. As far as we’re concerned though, it’s important to note that they’re all in either East or West Sussex.

Sussex is an ideal location for integrating solar panels with heat pumps. This combination allows homeowners to use solar-generated electricity to power their ASHPs, further reducing their energy costs and enhancing the sustainability of their homes. The synergy between solar panels and ASHPs maximises the use of renewable energy sources, making it a compelling option for those looking to reduce their environmental impact and achieve greater energy self-sufficiency.

All These factors make our part of the world an optimal region for the deployment of ASHP technology, supporting the transition to more sustainable energy solutions while addressing the specific needs and opportunities presented by the local environment.

Benefits

Switching to an air source heat pump like the Ecodan not only means enjoying the warmth of your home in a more energy-efficient and environmentally friendly way, but also offers significant cost savings. These systems are designed to use less energy while maintaining high comfort levels, which is great for the planet and your wallet. Unlike traditional heating methods that rely on oil or gas, running a heat pump typically results in lower monthly bills. This shift can reduce your worry about the fluctuating costs of fossil fuels, making it an economically wise choice for homeowners in Sussex.

Plus, there’s more good news on the financial side from the government as well. The Boiler Upgrade Scheme (BUS) offers grants to help homeowners in England and Wales make the switch to greener heating systems like air source heat pumps. This initiative can significantly offset the upfront installation cost, making it an even more attractive option for those considering an eco-friendly upgrade.

These factors make air source heat pumps a compelling choice for homeowners in Sussex looking to boost their home’s efficiency and comfort while keeping an eye on their budget and the environment.
