PulsaCoil No Hot Water

Various factors could result in a PulsaCoil no hot water

If your PulsaCoil system is not producing hot water, several potential issues could be causing the problem:

Faulty Immersion Heater: The immersion heater within the PulsaCoil might be malfunctioning or burnt out, leading to a lack of hot water.

Thermostat Problems: Issues with the thermostat, such as being set too low or malfunctioning, can prevent the PulsaCoil from heating the water to the desired temperature.

Limescale Buildup: Over-time, limescale can accumulate within the system, affecting its efficiency and ability to heat water.

Airlocks: Airlocks within the system can block the flow of hot water, leading to a lack of hot water at the taps.

Faulty Pump: If the pump responsible for circulating water through the PulsaCoil is faulty or not functioning correctly, it can hinder the distribution of hot water.

System Pressure: Low system pressure can impact the circulation of water through the system, resulting in inadequate heating.

Electrical Issues: Problems with the electrical supply or wiring can prevent the PulsaCoil from functioning properly.

Component Wear and Tear: Components within the PulsaCoil, such as valves or seals, may wear out over time, leading to issues with heating hot water.

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.
