Before you book: heat pump radiator upgrades in Forfar
The question for a Forfar 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 Forfar, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Forfar is scheduled with your heat pump installation so the system is drained only once.
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 that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
What's included
- Balancing every radiator so each room heats evenly
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Room-by-room heat loss figures for every heated room
Extensions and kitchen-diners around Forfar 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 Forfar 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.

How long is the heating season in Forfar?
On the shortest day Forfar gets only about 6 hours 48 minutes of daylight, with the sun around 10° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Forfar: questions
What size heat pump does a Forfar 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 Forfar home.
Can you service a heat pump in Forfar that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Forfar, whoever fitted them. Tell us the make and model when you book.
Do you cover Kirriemuir as well as Forfar?
Yes. We arrange surveys and installation in Kirriemuir, which is about 5 miles north-west of Forfar, and across Angus and Dundee.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
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.
