@plumbingdoctors: -1°C outside… stone cold inside 🏥 Turned up to a doctor’s surgery with no heating at all — staff didn’t even know they had underfloor heating 👀 After some fault-finding, I discovered a failed wiring centre that wasn’t powering the pump. The control signals were there… but no circulation = no heat. Big shout-out to Nu-Heat for excellent technical support 👍 Temporary emergency fix got them through the freezing night, then I returned to carry out one of the most complex wiring swaps I’ve done. ✔ Underfloor heating restored ✔ Pump running ✔ Heat back throughout the building 👉 Full diagnosis + repair on YouTube #NoHeating #UnderfloorHeating #HeatingEngineer #FaultFinding #UKTrades
