Diagnosis: Where Control Decisions Go Wrong
The biggest regret we hear is investing in a flashy smart thermostat for a system that's fundamentally uncontrolled elsewhere. If you have one thermostat in a hallway, and no thermostatic radiator valves (TRVs) on individual radiators, that's where to spend your money first. A basic system with one main thermostat can't address different heating needs across your home. Pumping heat into an unused spare room while another area is cold isn't efficient, no matter how clever your thermostat is. This is particularly true for larger properties or Victorian terraces in Wigan with varied room uses.
- One thermostat for the whole house
- No TRVs on radiators
- Ignoring fundamental system issues
- Over-reliance on remote control apps
