Installing heat pumps in challenging properties such as flats, apartments and older homes can be tricky, but it is far from impossible. In this episode of Homeowners’ Q&A Rob Stevens from Heat Force, Rick Clarke from NIBE and Barry Sharp from Renewable Heat tackle some of the trickiest questions about how heat pumps can be installed in challenging properties and places. Whether it’s dealing with the tight spaces of an apartment or managing high ceilings in a barn conversion, the episode delves into solutions for these unique heating challenges.
One key topic discussed was the installation of Exhaust Air Heat Pumps (EAHPs) in flats and apartments. Rick Clarke explained that EAHPs are a highly efficient solution that doesn’t require external units, making them ideal for properties where outdoor space is limited or non-existent. Unlike traditional air source heat pumps, which need access to external air, EAHPs utilise warm, extracted air from inside the building, making them perfect for flats with integrated ventilation systems. However, as Rick pointed out, while EAHPs are widely adopted in Europe, their use in the UK is still in its infancy.
Moving from flats to houses, Rob Stevens shed light on installing heat pumps in older, hard-to-insulate properties. These homes, often built before 1919, tend to have stone walls and minimal insulation, making them difficult to heat efficiently. Barry Sharp added that even with solid stone walls, a heat pump can still perform well if homeowners focus on addressing air leaks and upgrading windows and doors. Interestingly, Barry’s team found that many pre-1919 homes had lower-than-expected air changes per hour, meaning they retained heat better than expected, offering a viable setting for a heat pump installation.
Another fascinating part of the conversation came when a homeowner question asked if it’s possible to install an air source heat pump in an open garage or a semi-sheltered area. Rick gave an honest but cautionary response, explaining that while it is possible, it’s not ideal due to potential issues with airflow recirculation and reduced efficiency. He stressed that proper airflow is key to ensuring the pump doesn’t struggle to pull in fresh air, which would otherwise reduce its performance and lead to increased energy bills.
This episode was packed with tips and insights into how heat pumps can be adapted to fit into even the most challenging of properties. Whether you live in a flat, a farmhouse, or even a houseboat, there’s a solution for you.
