Sizing Radiators for 45°C Heat Pump Water

A traditional boiler pumps water at 70°C, meaning small single-panel radiators could heat a room. A heat pump runs at 45°C–50°C. By upgrading key rooms to double-panel double-convector (Type 22) radiators, you achieve equal or superior heat output while saving energy.

settings_suggest Our Radiator Upgrade Process:

  • verifiedWe calculate the Delta T (ΔT 30) output requirement for every room based on laser measurements.
  • verifiedWe identify which existing radiators can be retained and which need replacement.
  • verifiedWe drain, flush, and chemically treat the heating system to ensure silent, corrosion-free flow.
  • verifiedWe balance every radiator lockshield valve to guarantee balanced heat delivery across all floors.

We offer a wide selection of British and European manufactured radiators with 10-year manufacturer guarantees.

Frequently Asked Questions

Everything you need to know about engineering standards, grants, and living with renewable systems in Kent.

help Do I really have to replace all my radiators for a heat pump?

Rarely. In typical Kent homes, only 30% to 50% of existing radiators need upgrading. Frequently, rooms with double-panel radiators already have sufficient output.

help Can I have traditional cast-iron style column radiators?

Yes! Modern multi-column steel radiators look identical to traditional cast iron but heat up much faster and have excellent heat dissipation at low flow temperatures.

help What if my home has microbore (8mm or 10mm) pipework?

Microbore pipework can work with heat pumps provided flow rates are verified. During our survey, we check pump head and pipe capacity to confirm suitability.

help How long does it take to change radiators?

Our team can replace and balance 6 to 10 radiators in a single day with zero disruption to your carpets or decor.
