Many homeowners with period properties assume air source heat pumps won’t work in their Victorian terraces or Edwardian semis. I hear this concern almost daily at Air To Heat, and honestly, it’s one of the biggest myths we need to tackle.
The truth? Older homes can absolutely benefit from heat pump technology. Yes, they come with quirks that newer builds don’t have, but that doesn’t mean you’re stuck with your ageing oil boiler forever.
The Real Challenge (And It’s Not What You Think)
The main issue isn’t the age of your property. It’s insulation. Heat pumps operate at lower flow temperatures than traditional gas boilers, typically around 45-55°C compared to 65-75°C. This means heat is delivered more gently and consistently.
For this to work efficiently in an older property, you need decent insulation. We’re not talking about turning your home into a sealed box, but simple improvements make a massive difference. Loft insulation, cavity wall insulation where possible, and draught-proofing around windows and doors are usually sufficient.
Before we install any system, we check your EPC rating. If it flags outstanding insulation recommendations, we’ll discuss these openly. Sometimes it’s worth investing £2,000 in insulation before spending on a heat pump. Other times, your property is already better insulated than you’d expect.
Radiators and Underfloor Heating
Another common worry is radiators. The good news is that most existing radiators work fine with heat pumps. Occasionally, we recommend upgrading to larger radiators in one or two rooms to compensate for lower water temperatures, but this isn’t always necessary.
We’ve successfully installed heat pumps in properties dating back to the 1890s across South East London. Each installation is different, which is why our site surveys are thorough. We measure radiator sizes, check pipe runs, and assess outdoor space for the unit.
Government Support for Period Properties
The £7,500 Boiler Upgrade Scheme applies to older properties too, provided you meet the basic criteria. We’ve helped countless homeowners in period homes claim this grant, significantly reducing their upfront costs.
