Heat pumps work differently from boilers. A boiler typically heats a home in bursts, switching on hard for a few hours in the morning and evening. A heat pump is usually most efficient running 'low and slow': keeping water at a modest temperature for longer and holding rooms at a steady temperature rather than reheating them from cold. Many people find this takes a week or two to get used to.
We set up weather compensation for each Glasgow and Dunbartonshire home from its own heat loss design, not a factory default. If an existing heat pump in Glasgow and Dunbartonshire feels costly to run, a controls check is often the first thing to look at. For Glasgow and Dunbartonshire homes with extensions, we plan zones so the new space heats properly without making the heat pump cycle.
Who it suits
- Homes with solar PV or a battery that want hot water timed to match
- Existing heat pumps that feel expensive to run or slow to respond
- Every new heat pump installation, set up at commissioning
- Homes with an extension, loft room or areas heated at different times
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 home in Glasgow and Dunbartonshire, 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 controls and tariffs questions
Is a heat pump tariff a good idea?
A heat pump or time-of-use tariff can lower running costs if your household can shift hot water heating and some space heating into the cheaper periods. Whether it suits you depends on the rates, the standing charge, your routine and whether you have a battery. Compare the total expected cost on your own usage, not only the headline rate.
How should I set the hot water on a heat pump?
Most households heat hot water once or twice a day at set times rather than on demand. Timing the main heat for a cheaper tariff period, or for the middle of the day when solar panels generate, helps keep costs down. A weekly legionella cycle raises the water temperature higher, and we schedule it at a sensible time.
Why are my radiators only warm, not hot?
That is normal for a heat pump. It heats radiators to a lower temperature than a boiler, so they feel warm rather than hot to the touch, while running longer to keep the room at a steady temperature. If rooms reach the temperature you set, the system is working as designed. If a room stays cold, the settings or radiator size may need checking.
Should I turn my heat pump off at night?
Usually not. Switching off lets the house cool, and the heat pump then has to run at a higher flow temperature to recover, which lowers efficiency. A small set-back of 1–2°C overnight is generally more economical. Homes with very good insulation or a time-of-use tariff may suit different patterns, which we can set up.
