The challenge of heating multiple-occupancy residential buildings
Why is heating flats, maisonettes and small terraced buildings different from other homes, asks Ambion Heating
Much of the focus of decarbonising home heating has understandably been on replacing gas boilers, as a significant source of carbon emissions. Detached and semi-detached homes offer more space flexibility for external units and are well-suited for air source heat pump installations. However, there’s another challenge that isn’t getting the attention it deserves. And that’s how to effectively heat small homes and multiple occupancy buildings such as flats, maisonettes and terraced homes.
These homes make up a third of the UK’s housing stock and half of social housing, particularly in cities.
For these property types we need another approach. One that works within the constraints of space while still delivering affordability, comfort and flexibility. This is especially true as decarbonising home heating remains one of the biggest hurdles in the UK’s net zero journey.
This is where infrared heating comes in as a simple and cost-effective alternative. Ambion’s system, in particular, goes beyond just heating homes and is designed for precision, control and long-term efficiency. This practical, future-proof alternative to traditional heating systems helps landlords, social housing providers and developers meet both cost and sustainability targets.
Why is heating flats, maisonettes and small terraced buildings different?
Heating multiple-occupancy buildings presents distinct challenges that set them apart from other homes. Unlike houses with ample outdoor space, flats and maisonettes often lack room for bulky heating infrastructure such as external heat pump units. Internal space is also at a premium, making large radiators and extensive pipework undesirable.
Another major factor is affordability. For social housing providers, finding a low-carbon heating system that is both cost-effective to install and maintain is a top priority. Some properties require significant upfront investment or costly modifications to the building to transition from gas-fired boilers, creating barriers to adoption. With upfront costs typically lower than latest-generation storage heaters, and no moving parts to maintain, the Ambion system keeps replacing heating systems in budget.
Regulatory requirements add another layer of complexity. Housing providers must ensure their heating systems comply with evolving energy efficiency and emission standards, including EPC targets. This means selecting solutions that not only deliver immediate benefits, but also future-proof properties against tightening regulations and increasing sustainability expectations. The Ambion system can help housing providers achieve target EPC scores by integrating easily with a range of energy efficiency measures, including smart water heating systems and solar PV.
A smarter approach to low-carbon heating
Ambion’s system provides an innovative and effective way to heat flats, maisonettes and small terraced homes without the drawbacks of traditional systems. Unlike convection-based heating, which warms the air in a room, infrared heating works by directly warming the building fabric, including walls, floors and furniture. This approach delivers a more consistent and comfortable heat, eliminating cold spots and reducing heat loss through ventilation.
Another key benefit of infrared heating is its space efficiency. Slimline panels can be discreetly installed on walls or ceilings, eliminating the need for radiators, boilers and pipework. This makes it an ideal space-saving solution for buildings which need to make efficient use of what is available, allowing for more flexible room layouts and improved aesthetics. Additionally, installation is straightforward and minimally disruptive. Unlike heat pumps, which can require home modifications and specialist installers, any qualified electrician can fit infrared panels, significantly reducing installation time and costs.
Beyond practicality, the Ambion system offers significant cost savings for tenants. Running costs for a two-bedroom flat typically range between £35 and £45 per month, which can be further reduced by integrating the system with solar PV and smart energy tariffs. The practical nature of our infrared heating system means that less energy is wasted, resulting in lower overall consumption and more predictable bills. For social housing providers and landlords of flats, this makes it an attractive long-term investment, balancing sustainability with financial viability.
Tackling damp and mould while improving comfort
Heating systems in social housing and rental properties must also comply with regulations such as Awaab’s Law. Introduced in July 2023, the law requires landlords to respond to reports of damp and mould within set timeframes or face potential penalties.
Another major advantage of infrared heating is its ability to combat damp and mould. By warming the building fabric rather than just the air, Ambion’s system helps to maintain dry, stable indoor conditions, reducing the risk of condensation and mould growth. This is particularly important in smaller, poorly ventilated homes, where damp-related health issues can be a significant concern. Improved air quality also enhances overall living conditions. There is no circulating air to distribute dust and allergens, making the system particularly beneficial for residents with respiratory conditions.
Comfort and usability are equally important considerations. Recent testing at Energy House 2.0 has demonstrated that Ambion’s system delivers fast heat-up times, consistent temperature distribution and precise control. Unlike traditional radiators, which can create uneven warmth and require time to reach optimal temperatures, our system provides an immediate and steady heat output. Residents can easily manage their heating through the user-friendly touch-screen control panels, allowing for greater control over comfort levels and energy consumption.
Future-proofing homes with smart, flexible heating
As the UK moves towards a decarbonised future, flexible heating solutions will be crucial for flats, maisonettes and small terraced homes. The Ambion system integrates seamlessly with solar PV and smart energy tariffs, enabling landlords and residents to further reduce energy costs and carbon footprints. By using unique load-balancing algorithms, our system spreads heat demand evenly over a 24-hour period, minimising peak loads and ensuring a stable energy supply. This makes it particularly well-suited to the evolving energy grid, where demand-side response and load balancing are becoming increasingly important.
Smart data insights also add value for landlords and housing providers. Our system provides real-time monitoring of energy use, temperature patterns and efficiency levels, all accessible via a remote dashboard. This data allows for proactive energy management, helping providers optimise efficiency, reduce costs and support compliance with regulatory standards and requirements.
A practical, proven solution for decarbonising heating
The transition to low-carbon heating does not have to be complex or expensive. Infrared heating offers a smart, cost-effective and proven alternative to traditional systems, particularly for flats, maisonettes and small terraced homes where space and affordability are key concerns.
For social housing providers, developers and landlords looking for a reliable and future-ready solution, the Ambion system presents a compelling choice. With benefits ranging from easy installation and low maintenance to improved comfort and air quality, it represents a practical and scalable way to decarbonise heating while keeping costs under control. As the UK transitions towards net zero, exploring a range of technologies will be crucial in shaping the future of home heating, delivering warmth, efficiency and sustainability for generations to come.
