We’re proud to be an approved installer of the Luthmore boiler, a new generation of zero emission home heating system designed to replace traditional gas combi boilers in UK homes. In this guide we’ll explain what the Luthmore boiler is, how it works and why it’s attracting interest from homeowners, developers and heating professionals alike.
The Luthmore boiler is a fully electric, battery-enabled boiler system that aims to offer the performance of a gas combi boiler without burning fossil fuels. Designed by former Dyson engineers, it delivers instant hot water and central heating in a compact, wall-mounted unit that can fit into the same cupboard space as a traditional combi boiler. It uses advanced Lithium Iron Phosphate (LFP) battery modules to store electrical energy and release it when required for heating and hot water, making it a genuinely zero emissions alternative to traditional gas systems.
The idea behind the Luthmore is simple: provide homeowners with a familiar heating experience, but without the harmful carbon emissions. As it runs entirely on electricity and battery storage, it eliminates the need for a gas supply, combustion chamber or flue. This not only reduces onsite disruption during installation, but also removes the risks associated with gas heating.
At the heart of the Luthmore boiler is a bank of high-capacity LFP batteries that act as an energy store. These batteries can be charged from the grid during off-peak hours when electricity is cheaper, or from rooftop solar panels if available, storing power until it is needed. When there is a call for hot water or heating, the stored energy is released to deliver powerful performance that matches typical gas combi outputs.
Instant hot water is delivered at up to 30 kilowatts, equivalent to many traditional gas combi boilers, while central heating is supplied at up to 10 kilowatts, giving homeowners reliable warmth and a consistent flow of hot water even during peak demand. As the Luthmore is tankless and flueless, the unit requires minimal space and typically connects to existing pipework and radiators. This means many properties can switch to the Luthmore boiler without major changes to their heating infrastructure.
The system is controlled by an intuitive interface and app, allowing homeowners to track their energy usage, manage charging times and optimise costs. Choosing to charge batteries off-peak or use solar power can help reduce running costs and carbon impact, giving users greater control over how and when their heating operates.
One of the most compelling reasons for considering the Luthmore boiler is its zero emissions operation at the point of use. As it does not burn gas, there are no direct carbon emissions from heating or hot water. As the UK grid continues to decarbonise, systems like Luthmore become even greener over time compared with fossil fuel-based alternatives.
The design also aligns with future building standards such as the Future Homes Standard, which aims to ensure new homes are built with low-carbon technologies. Luthmore fits directly into existing homes and new builds alike without extensive retrofitting and therefore provides a practical route towards meeting these evolving standards.
One of the key benefits of the Luthmore boiler is its simplicity. For installers and homeowners used to traditional boilers, the familiarity of a wall-mounted combi size and standard connections make the transition easier than moving to systems such as ground or air source heat pumps that often need larger radiators, outdoor units or tanks.
For small and medium sized homes where heat pumps may not be suitable or cost-effective, Luthmore offers a compelling middle ground: reliable, familiar performance with a significantly lower carbon footprint. Installation is less disruptive and typically quicker than installing more complex systems, and maintenance requirements are reduced because there is no combustion chamber or flue to service.
The ability to store off-peak electricity and release it during peak demand also gives homeowners the potential to manage their energy costs more effectively, Coupled with smart controls and integration with solar power, this system can help households reduce their heating bills and environmental impact simultaneously.
The Luthmore boiler is ideal for homeowners who want to move away from gas without sacrificing the performance and convenience of a combi boiler. It is particularly well suited to small and medium sized homes, flats, and properties off the gas grid. As it uses your existing radiators and pipework, many installations involve minimal disruption compared with alternatives such as heat pumps.
That said, every home is different. Factors such as insulation, electrical supply capacity and hot water demand should all be carefully considered before choosing a heating system. We assess each property individually to ensure the solution we recommend will deliver comfort, efficiency and long-term value.
Installing a Luthmore boiler requires specialist knowledge and training. As approved installers, HeatElectric brings the expertise needed to size the system correctly, plan the electrical supply and integrate the boiler with your existing heating system. We ensure that installation is smooth, compliant and tailored to the needs of your home.
Our team also walks you through how the system operates and how to get the most from its smart controls so that you feel confident managing your new heating system from day one.
