Heating Control Wiring Specialists Across Northamptonshire

Entigen diagnoses and repairs the electrical side of domestic heating control systems across Kettering, Northampton, Wellingborough, Corby, Market Harborough and surrounding Northamptonshire towns.

Many heating and hot water issues are caused by faults within the electrical control system rather than faults within the boiler itself. If the boiler is healthy but the heating is not responding, the fault may be within the electrical control circuit.

We test the electrical side of heating systems, including switched lives, control wiring, thermostats, smart heating controls, receiver wiring and wiring centre connections. We stay firmly within electrical work: heating controls, fault finding, wiring and safe testing.

Electrical Controls We Check
  • Wiring centres
  • Heating programmers and timers
  • Room thermostats
  • Smart thermostats and receivers
  • Tado, Hive and Nest controls
  • S-plan and Y-plan control wiring
  • Motorised valve wiring
  • Switched live and demand circuits

What We Do Not Do

Entigen does not carry out boiler servicing, boiler repairs, gas work, radiator repairs, plumbing repairs, power flushing or central heating installation. If the fault is within the boiler, gas appliance or plumbing system, a suitably qualified heating or gas engineer will be needed.

Heating or Hot Water Not Responding?

Heating Not Working? When The Fault May Be Electrical

No Demand Signal
The room thermostat or programmer may appear normal, but the switched live signal may not be reaching the boiler, pump or motorised valve.
Timer Problems
A programmer or timer can fail internally, lose its supply, or have old wiring that no longer matches the heating control layout.
Receiver Faults
Tado, Hive and Nest receivers need the correct permanent supply and switched outputs. A small wiring error can stop heating or hot water responding.
Valve Wiring
Motorised valves contain switches that tell the boiler when to fire. Incorrect or failed valve wiring can stop heating or hot water even when the boiler is otherwise healthy.
Thermostat Wiring
Room thermostats and smart thermostats may need permanent live, neutral and switching conductors depending on the model and system type.
Intermittent Faults
Loose terminals, altered wiring, moisture, failed relays or poor previous work can cause heating controls to behave inconsistently.
Common Control Faults

Common Heating Control Faults We Attend

Heating Won't Turn On
The likely electrical causes include a missing switched live, failed room thermostat, faulty programmer output, open circuit in the wiring centre or motorised valve end switch not proving. Entigen tests the control circuit in sequence so the failed electrical point is identified rather than assumed.
Heating Won't Turn Off
Heating that continues running can be caused by a permanently energised switched live, incorrect programmer wiring, a relay fault, or a motorised valve control issue. We isolate and test the control outputs before deciding whether the fault is in the wiring, thermostat, programmer or receiver.
Hot Water Not Working
Where hot water is controlled electrically, faults can involve the cylinder thermostat, programmer hot water channel, wiring centre terminals, motorised valve wiring or demand signal. We check the electrical controls and switching path, while keeping boiler and plumbing work outside our scope.
One Zone Not Heating
A single heating zone can fail because the zone thermostat, programmer channel, motorised valve wiring or wiring centre output is not switching correctly. We compare the working and non-working zones and test for supply, demand and control continuity.
Tado Not Firing The Boiler
Tado may appear connected in the app while the receiver output is not sending the correct demand signal. Common electrical causes include missing permanent supply, incorrect relay terminals, incompatible control wiring or a misidentified switched live. We test the receiver and heating control circuit before altering connections.
Hive Receiver Faults
Hive receiver problems can come from incorrect backplate wiring, lost supply, failed switching output or previous programmer wiring that was not mapped correctly. Entigen checks the receiver supply, terminal function and demand output as part of the electrical diagnosis.
Nest Thermostat Problems
Nest issues can involve Heat Link wiring, supply problems, incorrect switching configuration or a control signal that is not reaching the heating circuit. We test the fixed wiring and receiver output rather than relying only on app status or visual wiring checks.
Motorised Valve Faults
Motorised valve faults can be electrical when the actuator, microswitch or associated wiring does not send the correct signal. We test the valve wiring and control circuit where safely accessible, and distinguish electrical control faults from mechanical or plumbing issues.
Wiring Centre Faults
A wiring centre fault may involve loose terminals, altered wiring, incorrect conductor identification or missing links between the programmer, thermostats and valves. We trace conductors, confirm supplies and test switched outputs before recommending the next electrical step.
Programmer Or Timer Not Switching
Programmers and timers can fail internally or be wired into older control arrangements that no longer match the current heating system. Entigen checks power supply, channel outputs and wiring centre connections to confirm whether the timer is faulty or the issue is elsewhere in the control circuit.
Wiring Centre Diagnosis

S-Plan, Y-Plan & Wiring Centre Fault Finding

S-plan and Y-plan heating systems rely on programmers, room thermostats, motorised valves and boiler demand signals working together. If one part of the electrical control circuit is wrong, the heating or hot water may not come on, may not switch off, or may respond to the wrong control.

A wiring centre fault can stop heating working because the correct demand signal may never reach the boiler, pump or motorised valve. We identify the system type, test the control wiring and confirm whether the fault sits in the electrical controls or elsewhere.

  • ✓S-plan controls — separate heating and hot water zone valve circuits checked methodically
  • ✓Y-plan controls — mid-position valve wiring and common terminal arrangements assessed correctly
  • ✓Wiring centres — conductor tracing, supply checks and switched live testing where safely accessible
  • ✓Control circuits — thermostats, programmers, receivers and motorised valve end switches tested together
Controls and Receivers

Programmer, Timer & Thermostat Wiring Problems

Many heating faults originate from thermostats, programmers, wiring centres, receivers or motorised valve wiring. The boiler may be waiting for a signal that is never arriving, or receiving a permanent demand signal from a wiring error.

We can replace suitable programmers, timers, room thermostats and smart thermostat receivers where the existing wiring and heating controls are compatible. We do not provide DIY wiring advice and we do not ask customers to open live wiring centres or boiler controls.

Valves and Demand Circuits

Motorised Valve & Heating Control Circuit Faults

A motorised valve can cause heating issues when its electrical switching does not operate correctly. The mechanical valve body may be part of the wider heating system, but the wiring, end switch and demand signal are electrical control points that can be tested.

If a valve, programmer or wiring centre has been changed previously, the heating may work in one mode but fail in another. We check the electrical route before suggesting replacement parts.

Smart Control Faults

Tado, Hive & Nest Smart Thermostat Fault Finding

Smart thermostats are only as reliable as the wiring and compatibility checks behind them. If your Tado, Hive or Nest app appears to work but the heating does not respond correctly, the issue may be receiver wiring, a missing permanent live, a misidentified switched live or an incompatible control arrangement.

Electrician-Led Diagnosis

Why Choose A Heating Controls Electrician?

If the issue is in fixed wiring, a wiring centre, a thermostat receiver, a programmer supply or a switched live circuit, it needs electrical testing rather than guesswork. A heating engineer may be needed for boiler, gas or plumbing faults; an electrician is the right call when the control circuit itself is suspect.

We focus on safe isolation, conductor identification, continuity testing, live testing where appropriate, and proving whether the electrical control side is doing what it should. That helps avoid unnecessary boiler call-outs where the real fault is in the controls.

For wider electrical work, see our main electrical services hub and domestic electrical services. For broader diagnosis beyond heating controls, our electrical faults and fixes page explains the wider fault-finding process.

Which Trade Do You Need?

Should I Call An Electrician Or A Heating Engineer?

Many homeowners are unsure whether a heating fault requires an electrician or a heating engineer.

If the boiler has power but the heating or hot water is not responding correctly, the issue may be within the electrical control system.

Electrical heating control faults commonly involve thermostats, smart thermostats, programmers, receivers, wiring centres, switched live circuits, motorised valve wiring and heating control circuits.

These issues require electrical testing and diagnosis. The aim is to confirm whether the control wiring is sending the correct demand signals before assuming the boiler itself is at fault.

If the fault is inside the boiler, gas appliance, burner, combustion system or gas controls, a Gas Safe engineer will normally be required.

If the fault is within the electrical controls, wiring or switching system, an electrician experienced in heating controls may be the correct trade.
