With energy costs still elevated across the UK, smart heating is one of the fastest-returning investments a homeowner can make. Here is what the numbers actually look like.
Heating accounts for the largest single share of most households' energy use — typically around 60% of an annual energy bill. Given that, even modest improvements in efficiency translate into meaningful savings. Smart heating systems, when properly designed and installed, consistently deliver reductions of 20–30% on heating costs for Bath homeowners.
What makes a heating system smart?
A true smart heating system goes well beyond a thermostat you can operate from your phone. The most effective systems include:
- Individual room control — each room has its own temperature schedule, so you only heat the spaces you actually use
- Occupancy detection — the system learns when rooms are occupied and adjusts automatically
- Weather compensation — boiler output adjusts based on outside temperature rather than running at full power regardless
- Open window detection — heating pauses automatically if a sensor detects a window has been opened
- Remote access — full control from anywhere via smartphone or tablet
Single zone vs multi-zone: what is the difference?
A single-zone system controls your whole house as one unit. If you want the kitchen warm in the morning but not the spare bedroom, a single-zone system cannot help you — everything runs together. A multi-zone system gives every room its own schedule and temperature, which is where the real energy savings come from.
For a typical four-bedroom Bath townhouse with separate living zones over several floors, multi-zone control can make a dramatic difference. Rooms that would otherwise be heated to 20°C all day while empty can instead be kept at a background temperature and brought up only when needed.
How quickly does it pay back?
For a professionally installed multi-zone smart heating system costing around £1,500, savings of £300–£500 per year on heating bills are achievable for a moderately sized Bath home. That puts the payback period at three to five years — after which the savings are ongoing.
The systems we install are compatible with all major boiler brands and heat pumps. If you are planning to move to a heat pump in future, we can install a system now that will work seamlessly with both.
Which brands do we install?
We work with Heatmiser, Honeywell Home, and Drayton Wiser for most residential applications. For whole-home integrated projects, smart heating is incorporated into the main control platform — whether that is KNX, Lutron, or Control4 — so everything works from a single app.
