We set up the controls at commissioning to suit your home and routine, show you how to use them, and explain how a heat pump tariff or time-of-use tariff could fit. Settings can be fine-tuned after the first cold spell, once you have seen how the house responds.
Hot water schedules in Clwyd can be timed to suit shift work, school runs or working from home. For Clwyd homes with extensions, we plan zones so the new space heats properly without making the heat pump cycle. We set up weather compensation for each Clwyd home from its own heat loss design, not a factory default.
Who it suits
- Homes with an extension, loft room or areas heated at different times
- Existing heat pumps that feel expensive to run or slow to respond
- Every new heat pump installation, set up at commissioning
- Households considering a heat pump or time-of-use electricity tariff
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your quote.
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.
Prices
Weather-compensating controls and set-up are included in every full system price. See the guide prices for full systems.

Heat pump controls and tariffs questions
What flow temperature should my heat pump run at?
It depends on the design: the flow temperature is set so your radiators or underfloor heating can heat each room on a cold day. Well-designed systems typically run at around 35–50°C at their coldest, and lower in milder weather through weather compensation. Your design paperwork states the design flow temperature, and we set the heating curve to match it.
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.
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.
