A smart thermostat is only as good as its installation. Most DIY installs leave OpenTherm modulation switched off (costing 5–10% efficiency), don't enable hot-water control properly on combi-DHW systems, and miss the proper geofencing setup that delivers the headline savings. The thermostat works, but it doesn't deliver the savings the manufacturer promised.
We install smart heating controls properly, wiring centre updated where required, OpenTherm enabled and verified with the boiler, hot-water schedule configured, weather compensation set up where supported, geofencing tied to all household phones, and a hand-over walk-through so you actually know how to use it. Average payback period properly installed: 18–30 months on heating bill savings.
