Heat pump radiators for Llantrisant homes
Most homes can run on a heat pump if the system is designed properly, and Llantrisant is no different. The key is matching the heat pump and radiators to the home's heat loss.
For period homes in Llantrisant and across Mid Glamorgan, column radiators can keep the character of a room while giving enough heat at low temperatures. Many older houses in Llantrisant still have their original single-panel radiators, so the survey checks each one against the room it heats.
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
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Pipework checks and any agreed pipe upgrades
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
- A radiator schedule showing which radiators stay, which change and their outputs
Extensions and kitchen-diners around Llantrisant with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in Wales
Homes in Llantrisant can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.
Heat pump radiators prices in Llantrisant
The ranges below are typical installed prices for homes in Mid Glamorgan, including VAT. A survey sets the exact figure, because two similar-looking houses in Llantrisant can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Llantrisant?
On the shortest day Llantrisant gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump radiator upgrades in Llantrisant: questions
How soon can you survey a home in Llantrisant?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Llantrisant?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Llantrisant home states the expected time.
Where would the outdoor unit go on a Llantrisant 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 Llantrisant home.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
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.
