No Hot Water? We Diagnose All System Types
When you have no hot water, the cause depends entirely on what type of hot-water system you have. We help you identify the source of the problem regardless of your system type.
Identifying Your System Type
The first step in diagnosing no hot water is identifying your system. A combi boiler failure is different from a tank failure. Look at your equipment: if you have a single unit that provides both heating and hot water without a separate tank, you likely have a combi boiler. If you have a separate tank, the problem could be in the tank or the heating source.
Common No-Hot-Water Scenarios
Combi boiler: diverter valve failure, sensors, or flow turbine. Indirect tank: zone valve, circulator, or tank sensor. Conventional tank: heating elements (electric), gas valve or thermocouple (gas). Tankless: flow sensor, gas supply, or control board.
Professional Diagnosis
Our technicians are trained on all hot-water system types. We carry diagnostic equipment and common parts for most systems to maximize the chance of a same-day repair.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
