Hot Water But No Heating in Kent | DAKS Plumbing
Hot Water But No Heating in Kent
If your taps are running hot but your radiators stay cold, you’re not alone. This is a common issue in Orpington, Dartford, Bexley, and nearby towns — especially when older boilers struggle to keep up with winter demand. In this guide, DAKS Plumbing explains why hot water but no heating in Kent happens, what you can check, and when to call our heating engineers in Kent for fast, expert help.

Main Causes of Hot Water But No Heating in Kent
When your boiler provides hot water but fails to heat radiators, one or more components are likely malfunctioning. Here are the most common reasons this happens in Kent homes.
1. Incorrect Thermostat Settings
Ensure your thermostat is calling for heat and set above room temperature. Flat batteries or lost wireless pairing are frequent causes. If you’re upgrading, consider a smart thermostat for efficiency and control.
2. Faulty Diverter Valve
In combi systems, a diverter valve directs heat between taps and radiators. A jammed valve can leave you with hot water only. This repair must be handled by a Gas Safe registered engineer. Our local team in Kent can replace it swiftly.
Checks Before Calling an Engineer
3. Boiler Pressure
Your boiler’s pressure should read about 1.2 bar. If it’s low, top up via the filling loop or contact our plumbing experts in Dartford for safe assistance.
4. Programmer or Timer Settings
After power cuts or clock changes, timers can lose schedule. Confirm your heating program is active and aligned with your routine.
Radiator and Circulation Issues
5. Air in the System
If radiators are warm at the bottom but cold on top, trapped air is blocking flow. Bleed them using a radiator key, or book a plumbing inspection for professional help.
6. Sludge or Blockages
Rust and debris, known as sludge, can clog your system. A professional power flush clears it and restores even heat. We also handle drainage blockages in Kent.
7. Circulation Pump or Motorised Valve Faults
A failed pump stops hot water reaching radiators. Humming or grinding noises from the boiler are warning signs. Our engineers provide fast central-heating repairs across Kent.
