Go green with Gasway

Why Renewable Heating?

Renewable heating solutions are growing in popularity, especially with the UK Government’s low carbon agenda. The burning of gas produces more carbon dioxide than any other domestic fuel, and to achieve net-zero by 2050, significant changes in the way we heat our homes are essential.

Switching to renewable heating not only helps the planet but can also reduce your energy bills, improve efficiency, and make your home future-proof. Gasway is proud to help homeowners across Norfolk, Suffolk, Colchester, and East Anglia transition to greener energy.

Go Green and Save

Renewable heating solutions can deliver impressive savings on household energy bills:

By combining technologies, such as pairing a heat pump with solar panels, you can maximise your savings while reducing your carbon footprint.

Types of Renewable Heating

There are several renewable heating solutions available. The most popular include:

Air Source Heat Pumps (ASHPs) – Absorb heat from outside air to warm your home and water efficiently, even at temperatures as low as -15°C.
Ground Source Heat Pumps (GSHPs) – Extract heat from the ground for efficient year-round heating.
Biomass Boilers – Burn renewable fuel such as wood pellets or logs for environmentally friendly heating.

Each system can be paired with solar panels or an EV charging point for a fully integrated, energy-efficient home.

Many of these solutions are eligible for funding through the UK Government’s Boiler Upgrade Scheme, making the initial investment more affordable.

Each of these heating systems can be made more efficient with the inclusion of Solar PV & battery storage.

Energy efficient partnerships - Felixstowe

Renewable heating solution case study

Customers in Runnacles Way, Felixstowe, have seen significant energy savings thanks to a £1.4m communal renewable heating scheme. Gasway, in partnership with Finn Geotherm, installed a ground source heat pump system, benefiting 113 Flagship Housing customers.

Energy savings: around 70% lower than previous bills
Carbon reduction: helping Flagship move toward carbon neutrality by 2050
Impact: reduced fuel poverty and long-term sustainable heating

This demonstrates the real-world benefits of renewable heating for East Anglia homeowners.

Air Source Heat Pumps (ASHPs): How They Work

Air source heat pumps are green, low-carbon alternatives to gas or oil boilers. They absorb heat from the outside air and transfer it to your home’s heating and hot water circuits.

Efficient heating: Heat output is greater than electricity input
Low-temperature operation: Heats homes effectively over longer periods
Ideal for upgrades: Consider upgrading insulation, larger radiators, or underfloor heating for maximum efficiency

Running Costs & Savings

Your savings depend on:

Home size and insulation – better insulation increases efficiency
Heating system design – underfloor heating is most efficient, but large radiators work too
Fuel costs – ASHPs use electricity but often cost less than oil or electric heating
Old system efficiency – replacing an inefficient boiler yields more savings
Controls usage – longer, lower temperature heating periods can improve efficiency

A typical ASHP installation costs £10,000–£15,000, with potential financial support through the Boiler Upgrade Scheme or the Renewable Heat Incentive (RHI).

Air source heat pumps (ASHPs) are a green, low carbon alternative to fossil fuel boilers. Air source heat pumps absorb heat from the outside air to heat your home and hot water. They can still extract heat when air temperatures are as low as -15°C.

Air source heat pumps need electricity to run, but because they are extracting renewable heat from the environment, the heat output is greater than the electricity input. This makes them an energy efficient method of heating your home.

Heat from the air is absorbed at low temperature into a fluid. This fluid passes through a compressor, increasing the temperature, and transfers that higher temperature heat to the heating and hot water circuits of the house.

Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. If you are installing an ASHP to replace a gas or oil boiler, you should consider whether you can also upgrade your insulation to get the most out of your ASHP. You might also consider fitting larger radiators or underfloor heating.

If you live in England, you may be eligible for a voucher to cover up to two-thirds of the cost of insulating your home under the Green Homes Grant scheme.

Air source heat pumps can lower your fuel bills, especially if you replace conventional electric or oil heating.
Air source heat pumps slower home carbon emissions.
It could provide you with an income through the UK government’s Renewable Heat Incentive.

Installing a typical system costs around £10,000 – £15,000.

Running costs will vary depending on several factors. These will include:

The size of your home and how well insulated it is
The room temperatures you are aiming to achieve
The design of the system

How much you can save will depend on what system you use now, as well as what you are replacing it with. Your savings will be affected by:

Your heat distribution system

If you have the opportunity, underfloor heating can be more efficient than radiators because the water doesn’t need to be so hot. If underfloor heating isn’t possible, use the largest radiators you can. Our expert surveyors will be able to provide you with advice tailored to your home.

Your fuel costs

You will still have to pay fuel bills with an air source heat pump because it is powered by electricity, but you are likely to save money on your fuel bills (depending on the type of heating you are replacing).

Your old heating system

If your old heating system was inefficient, you are more likely to see lower running costs with a new heat pump.

Using controls

Learn how to control the system so you can get the most out of it. You will probably need to set the heating to come on for longer hours, but you might be able to set the thermostat lower and still feel comfortable. Our installers will explain how to control the system so you can use it most effectively.

The Boiler upgrade scheme is designed to help homeowners in England and Wales making the initial costs of low carbon heating systems more affordable. For example biomass boilers, air-source heat pumps and ground source heat pumps.

You may be eligible to receive payments for the heat you generate using a heat pump through the UK Government’s Renewable Heat Incentive (RHI).
