What to know about heat pump radiator upgrades in Hemel Hempstead
The question for a Hemel Hempstead home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Radiator fitting in Hemel Hempstead is scheduled with your heat pump installation so the system is drained only once. Extensions and kitchen-diners around Hemel Hempstead with large glazed areas get their own radiator calculation.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homes switching from a gas, oil or LPG boiler to a heat pump
What's included
- Supply and fitting of new radiators, valves and brackets
- Room-by-room heat loss figures for every heated room
- A radiator schedule showing which radiators stay, which change and their outputs
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
We plan radiator upgrades in Hemel Hempstead so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Hemel Hempstead quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Hemel Hempstead?
Hemel Hempstead has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Hemel Hempstead: questions
How long does a heat pump survey take in Hemel Hempstead?
A home survey in Hemel Hempstead usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do you cover Berkhamsted as well as Hemel Hempstead?
Yes. We arrange surveys and installation in Berkhamsted, which is about 5 miles west of Hemel Hempstead, and across Hertfordshire.
Where would the outdoor unit go on a Hemel Hempstead house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Hemel Hempstead home.
Do I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
