Understanding Your Heating Options
When upgrading your heating system, the two most common options are a modern gas boiler or an air source heat pump.
Both systems can effectively heat your home and provide hot water, but they operate differently and suit different types of properties.
Choosing the right option depends on factors such as your property, budget and long-term goals.
How Gas Boilers Work
Gas boilers heat water using natural gas and distribute it through radiators or underfloor heating systems.
They are the most common heating system in UK homes and are known for their reliability and strong heat output.
Gas Boilers are best suited for:
• Homes with existing radiator systems
• Properties with standard insulation
• Lower upfront installation budgets
• Homes needing fast heating response
How Air Source Heat Pumps Work
Air source heat pumps extract heat from the outside air and use it to heat your home and hot water.
They operate at lower temperatures but are significantly more energy efficient than traditional boilers.
Air Source Heat Pumps are best suited for:
• Well-insulated homes
• Properties looking to reduce energy use
• Homes with underfloor heating or larger radiators
• Long-term energy savings

Making the Right Choice
Choosing between a gas boiler and an air source heat pump isn’t always straightforward.
The right option depends on your property, insulation, existing system and long-term goals.
While heat pumps offer excellent efficiency and lower carbon emissions, modern gas boilers can still be the most practical choice for many homes.
Every property is different — which is why getting the right advice matters.

Our Advice
Every property is different, which is why we don’t take a one-size-fits-all approach.
At Aqueous Heating and Plumbing, we assess your home, heating system and requirements before recommending the best solution.
In some cases, a modern high-efficiency boiler may be the best choice.

Boiler Upgrade Scheme (Government Grant)
The UK Government currently offers financial support to help homeowners switch to low-carbon heating systems through the Boiler Upgrade Scheme (BUS).
This scheme can significantly reduce the upfront cost of installing an air source heat pump, making it a more accessible option for many households.
What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme is a government initiative designed to encourage homeowners to move away from traditional gas and oil heating systems.
Eligible households can receive a grant towards the cost of installing an air source heat pump, helping reduce the overall installation cost.
This makes energy-efficient heating systems more affordable while supporting the UK’s move towards lower carbon emissions.
Am I Eligible?
Eligibility for the scheme depends on a number of factors, including:
• Property ownership (homeowners in England and Wales)
• Existing heating system (replacing fossil fuel systems)
• Basic insulation requirements (such as loft or cavity wall insulation where applicable)
We can help assess whether your property may qualify and guide you through the process.
