Heat Pump Radiator Upgrades
Radiator assessment and upgrades for homes moving to lower-temperature heating, using room heat demand and emitter output rather than simply fitting larger radiators everywhere.
Radiator upgrades for heat pumps
Output checks
Compare each room's heat demand with the radiator output available at the intended flow and return temperatures.
Radiator resizing
Select larger or higher-output radiators where the existing emitter cannot meet the design load.
Type changes
Consider different panel/convector arrangements where more output is needed within a limited wall space.
Valve work
TRV and lockshield replacement or adjustment where appropriate as part of the radiator work.
Pipework considerations
Check whether accessible pipework and connections are suitable for the revised radiator arrangement.
System balancing
Balance the heating system so upgraded emitters receive the intended flow.
Upgrade only the emitters that need it
Radiator upgrades should be based on calculated room demand and output at the proposed low-temperature conditions. Replacing every radiator without checking the numbers can add unnecessary cost and still miss weak rooms.

Heat Pump Radiator Upgrades FAQs
Why do heat pumps often need larger radiators?
Lower water temperatures mean each radiator emits less heat, so some rooms need a larger emitter to deliver the same room output.
Can I keep some of my existing radiators?
Yes, if their calculated output is adequate at the new system temperatures.
Do radiator upgrades help a boiler system too?
Larger emitters can also help some boiler systems run at lower flow temperatures, depending on the wider design.
