Heat pump radiators for Stirling homes
The question for a Stirling 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 Stirling, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. For period homes in Stirling and across Stirling, Falkirk and Clackmannanshire, 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.
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Extensions and loft conversions with large areas of glazing
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
Extensions and kitchen-diners around Stirling with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Stirling home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
Heat pump radiators prices in Stirling
Here are typical prices for heat pump radiator upgrades in Stirling, Falkirk and Clackmannanshire, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.
| 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 Stirling?
Stirling has about 6 hours 55 minutes of daylight at midwinter against 17 hours 39 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.
From survey to switch-on in Stirling
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Stirling home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Stirling: questions
How long does installation take in Stirling?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Stirling home states the expected time.
What size heat pump does a Stirling 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 Stirling home.
Where would the outdoor unit go on a Stirling 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 Stirling 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.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
