Thermostat Problems Causing Boiler Not Heating Water in Kent

One of the most common reasons your boiler is not heating water in Kent is a faulty thermostat. If your thermostat isn’t properly calling for hot water, the boiler may fail to heat water even if it powers on. Thermostat calibration issues, sensor faults, or wiring problems can all lead to no hot water.

Diverter Valve Faults Behind Boilers Not Heating Water in Kent Homes

The diverter valve controls whether your boiler sends heat to your radiators or hot water taps. If it gets stuck, many Kent homes experience no hot water while heating still works. Diverter valve repairs are a common fix we carry out across Kent properties with combi boilers.

Temperature Sensor Failures Leaving Kent Boilers Without Hot Water

Modern boilers use multiple sensors to control water temperature. When temperature sensors (thermistors) fail, your boiler may not heat water at all, or only heat water intermittently. Sensor replacement is often required to restore reliable hot water in Kent homes.

Low Boiler Pressure Preventing Hot Water in Kent Properties

When boiler pressure drops too low, safety controls often stop the boiler from heating water. In Kent, pressure loss may occur after bleeding radiators or from system leaks. Our engineers can top up pressure and identify the cause of pressure drops if your boiler keeps losing water pressure.

Limescale Buildup Blocking Hot Water in Kent Boilers

Hard water areas like Kent suffer from limescale, which builds up in heat exchangers and restricts water flow. As limescale thickens, your boiler struggles to heat water properly, resulting in lukewarm or cold water. Power flushing or descaling helps resolve these issues.

PCB & Control Board Failures Stopping Boilers from Heating Water in Kent

The PCB acts as your boiler’s brain. If this circuit board fails, your boiler may stop heating water entirely. PCB faults require expert diagnosis, but Plumble’s Kent-based engineers carry the tools and replacement parts to resolve PCB problems quickly.

Airlocks & Flow Problems Causing No Hot Water in Kent

Air trapped in your hot water system can prevent water from circulating and heating. This can cause boilers not heating water in Kent properties even though the boiler itself seems operational. Our engineers can clear airlocks and improve system flow.

Quick Checks Kent Homeowners Can Do

• Check that your thermostat is calling for hot water
• Inspect boiler pressure is between 1.0-1.5 bar
• Look for displayed fault codes on your boiler screen
• Ensure gas supply is active if you use a prepaid meter
