Fully Modulating Oil Boilers
Here at Sapphire Heat Solutions, we are the proud manufacturer’s of the UK’s most efficient Oil Boiler Range, the award winning Sapphire Boiler.
Available as Internal & External, and Combi or Heat Only models between 6 – 32 kW.
What makes our boilers different?
Our Sapphire Boiler is the ONLY fully modulating boiler on the market in the UK.
It first launched in 2021 and has become the number one boiler choice for many oil boiler installers since then.
Our boiler is crafted of the highest quality materials, and this reflected in our 25-year warranty on the fully stainless steel heat exchanger.

Why choose Sapphire Heat Solutions?
Full system design service
Air source heat pumps are low-temperature heating systems, so they function differently from traditional high-temperature fossil fuel boilers. Because of this difference, it’s crucial to carefully plan the installation to ensure the system can meet the specific heating needs of the property.
We can provide this service ourselves, giving you the peace of mind that your heat pump will be running at optimal efficiency.
Fully trained installers
Only approved Sapphire agents will be responsible for installing Sapphire heat pumps, ensuring the highest standards of quality and reliability.
Each agent has undergone dedicated training with us, equipping them with the technical expertise and product knowledge needed for a professional and efficient installation.
This guarantees that every Sapphire boiler is installed to our exact specifications, delivering optimal performance and peace of mind for our customers.
30+ years of experience
Sapphire Heat Solutions is proud to be part of the EOGB Group—an established name in the heating industry with nearly 35 years of experience in boiler and burner manufacturing.
As the team behind the Sapphire Boiler, the most efficient liquid-fuelled boiler currently on the market, we’re committed to delivering top-tier heating solutions that combine performance, reliability, and innovation.

Air source heat pumps use refrigerants to absorb heat energy from the air outside and convert it into useable energy to heat our homes and hot water.
The heat pump draws in air and passes it over an evaporator, where it comes into contact with a refrigerant (R290). This refrigerant has a very low boiling point, so it evaporates into a gas when exposed to the heat in the air, absorbing latent energy in the process.
The gas is then compressed, which raises its temperature further, before moving through a heat exchanger. At this stage, the refrigerant condenses back into a liquid, releasing its heat into the water used for the property’s heating system. The liquid refrigerant then returns to the evaporator, and the cycle continues.
In many cases, yes. Heat pumps are much more energy-efficient than traditional gas, oil, or electric heating systems. Over time, this can lead to significant savings on energy bills, especially if replacing older systems.
Heat pumps require minimal maintenance. Annual servicing by a qualified technician is recommended to ensure peak performance and system longevity.
This depends on several factors, including how well your property is insulated and ventilated. The closer your home aligns with modern building standards and regulations, the more suitable it will be for a heat pump installation.
You’ll also need sufficient outdoor space for the heat pump unit. Additionally, it’s important that the air source heat pump has enough clearance around it to ensure proper airflow. Recirculating air that has already passed through the evaporator can reduce the system’s efficiency and overall performance.
Installing an air source heat pump will lead to higher electricity use in your home.
However, this is typically offset by the elimination of gas or oil heating costs—unless you choose a hybrid (bivalent) system that uses a traditional boiler alongside the heat pump.
When considering a switch to a heat pump, it’s important to look at the overall heating expenses, balancing the rise in electricity costs against the potential savings from no longer needing gas or oil.

Air source heat pumps work differently from traditional fossil fuel heating systems.
They typically require larger surface areas—such as bigger radiators or underfloor heating—to distribute heat effectively, along with different pipework and connections. It’s best to consult a local heat pump installer who can visit your home to assess your existing heating setup.
They can advise you on whether upgrades like new radiators, pipework, or a hot water cylinder will be necessary to support a heat pump system.
At Sapphire Heat Solutions, we can provide a full package containing a Heat Pump, Smart Controller and a Hot Water Cylinder.
Yes, air source heat pumps can still operate efficiently even when outdoor temperatures drop below 0ºC.
Despite common misconceptions, models such as our R290 range, are designed with advanced features that allow them to perform reliably in freezing conditions.
