Heat Pump Heating Zones and Controls
Proper zoning saves 10-15% on heat pump running costs by only heating the spaces you are using. Weather compensation — automatically adjusting flow temperature based on outdoor conditions — saves another 10-20%. Together, they make your heat pump as efficient as possible.
Controls are where many of the running cost savings from heat pumps are won or lost. See our flow temperature guide for the efficiency connection. Pillar: radiators and heat pumps.
Heating Zones Explained
Zones allow different areas to be heated independently. Minimum recommendation is two zones (upstairs/downstairs). UFH systems typically have one zone per room via the manifold.
Weather Compensation
The most important control feature. Automatically adjusts flow temperature based on outdoor temperature. Ensures the heat pump always runs at the lowest effective temperature, maximising COP. Most modern heat pumps include this as standard — it should always be enabled.
Smart Thermostats
Smart thermostats add convenience and learning capabilities but are not essential. The weather compensation curve is more important than a smart thermostat. If you have solar panels, smart controls can schedule heating to coincide with peak solar generation for lowest costs.

Frequently Asked Questions
How many zones should I have?
Minimum two (upstairs/downstairs). More zones give greater control. UFH typically has one per room.
Do I need a smart thermostat?
Beneficial but not essential. Weather compensation is more important.
Heating zones and controls are critical for heat pump efficiency. Connects to flow temperature, radiator sizing, and running costs. Solar panels with smart controls enable lowest-cost heating.
