Heat pump radiators for St Albans homes
The question for a St Albans 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.
In St Albans, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. For period homes in St Albans and across Hertfordshire, column radiators can keep the character of a room while giving enough heat at low temperatures.
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.
- Rooms with little wall space, where a fan-assisted radiator fits better
- Homeowners who want the lowest practical flow temperature for efficiency
- Extensions and loft conversions with large areas of glazing
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Balancing every radiator so each room heats evenly
- Supply and fitting of new radiators, valves and brackets
- Room-by-room heat loss figures for every heated room
- Making good around brackets and pipe routes, with any decorating agreed in your quote
Many older houses in St Albans still have their original single-panel radiators, so the survey checks each one against the room it heats.
Grants and rules for heat pumps in England
Homes in St Albans can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.

Designing for St Albans's winters
St Albans 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 St Albans: questions
Can you service a heat pump in St Albans that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in St Albans, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a St Albans home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your St Albans home.
Where would the outdoor unit go on a St Albans 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 St Albans 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.
