When the boiler runs but a room stays cold
A running boiler does not prove that every Gardiner heating zone receives hot water. Zone valves, circulators, air in the loop, controls, and thermostat calls need to be considered separately. Note which zones work and whether the symptom changes when another zone starts.
Describe domestic hot water separately
If a boiler also serves hot water, tell us whether the complaint affects room heat, faucets, or both. That helps keep a circulation fault from being confused with a water-heater problem. Residential piping or fixture work can be discussed alongside heating connections, with the scope confirmed before work is arranged.
