Before you book: heat pump radiator upgrades in Renfrew
In Renfrew, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Many older houses in Renfrew still have their original single-panel radiators, so the survey checks each one against the room it heats. Extensions and kitchen-diners around Renfrew 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 that already feel slow to heat, such as bay-windowed living rooms
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- A radiator schedule showing which radiators stay, which change and their outputs
For period homes in Renfrew and across Renfrewshire and Inverclyde, column radiators can keep the character of a room while giving enough heat at low temperatures.
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 Renfrew home, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Renfrew property at survey.

Short winter days in Renfrew and what they mean
On the shortest day Renfrew gets only about 6 hours 58 minutes of daylight, with the sun around 11° 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.

Heat pump radiator upgrades in Renfrew: questions
What size heat pump does a Renfrew 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 Renfrew home.
How long does installation take in Renfrew?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Renfrew home states the expected time.
How long does a heat pump survey take in Renfrew?
A home survey in Renfrew 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 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.
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.
