Some radiators may need upsizing, but in most Edinburgh and Lothians homes you don't need to rip out every radiator.
Here's the practical reality. Gas boilers typically run at 65-75°C. Air source heat pumps run more efficiently at 35-50°C. At those lower temperatures, a radiator puts out less heat — so to deliver the same warmth to a room it either needs to be larger, be a double panel instead of a single, or be a modern low-temperature type.
During the survey we do a room-by-room heat loss calculation and check every existing radiator against it. Typically:
- Bedrooms and smaller rooms often have radiators already big enough to work fine
- Living rooms and larger rooms are where upgrades are most often needed
- Kitchens depend heavily on layout and the existing setup
We'll write up a clear list of which radiators stay and which need changing, and include it in the fixed-price quote so you're not guessing. If a whole-system upgrade isn't worth it for your home, we'll tell you that too.
