PulsaCoil 3 No Hot Water

Several reasons could lead to a PulsaCoil 3 no hot water

Faulty Immersion Heater: The immersion heater in the PulsaCoil 3 might be defective or burned out, preventing it from heating the water.

Thermostat Issues: Malfunctioning thermostats can lead to inaccurate temperature readings or prevent the heater from activating when needed.

Limescale Buildup: Over time, limescale can accumulate in the system, reducing the efficiency of the heat exchanger and affecting water heating.

Airlocks: Airlocks within the system can block the flow of hot water, preventing it from reaching the taps or shower.

Faulty Pump: A malfunctioning pump responsible for circulating water through the PulsaCoil 3 could hinder the distribution of hot water.

System Pressure: Low system pressure can impede water circulation, resulting in insufficient heating.

Electrical Problems: Issues with the PCB board, electrical supply or wiring can prevent the PulsaCoil 3 from functioning correctly.

Component Wear and Tear: Components such as valves, sensors, or seals may degrade over time, leading to issues with the heating system.

Insufficient water: Insufficient water in the thermal store can often result from either evaporation or leaks within the internal thermal cylinder or immersion heater. When the thermostat sensor malfunctions or a relay remains stuck open, it can lead to a condition known as “kettling,” causing the system to generate steam and thereby accelerate internal water evaporation within the cylinder. This ultimately leads to a shortage of hot water at the tap outlets. You can independently gauge your hot water levels by referring to our DIY video tutorial.

Failure of the external economy-seven time clock: This can prevent the ‘off-peak’ immersion from heating overnight, leaving the internal cylinder cold.
