Heat pump controls are the settings and devices that decide how warm the water in your heating is, when the heat pump runs and when it heats hot water. The most important is weather compensation, which raises the flow temperature gradually as it gets colder outside and lowers it in milder weather, so the system only ever runs as warm as it needs to.
We set up weather compensation for each County Fermanagh home from its own heat loss design, not a factory default. For County Fermanagh homes with extensions, we plan zones so the new space heats properly without making the heat pump cycle. Homeowners in County Fermanagh get a walkthrough of their controls at handover, with a simple written guide to keep.
Who it suits
- Existing heat pumps that feel expensive to run or slow to respond
- Homes with solar PV or a battery that want hot water timed to match
- 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 Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a home in County Fermanagh is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey 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
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.
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.
Can I control my heat pump from my phone?
Many heat pumps offer an app or work with smart thermostats, letting you change temperatures, set schedules and see energy use from your phone. Features vary by make and model, and app control usually needs a reliable internet connection at home. The heating keeps running on its own settings if the connection drops.
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.
