Gledhill Pulsacoil Repair London began with a clear purpose: to expertly fix and install a range of Gledhill Pulsacoil systems. We specialise in Pulsacoil 3, Pulsacoil 2000, and Pulsacoil A-Class. Our passion stems from ensuring every home has a reliable and efficient hot water system, providing comfort and peace of mind.

The types of Pulsacoil that we remove and install or repair

Pulsacoil 3

The PulsaCoil 3, manufactured by Gledhill, is an electrically heated thermal storage system that has been discontinued and is intended to deliver mains-pressure hot water.

Rather than maintaining large quantities of pressurized hot water, it heats water as needed through an internal plate heat exchanger and pump system, which is managed by a printed circuit board (PCB).

System Design and Operation Thermal Store: It utilizes off-peak electricity, such as that provided by Economy 7, to heat water overnight within an open-vented cylinder. On-Demand Hot Water: A flow switch identifies when a hot tap is opened, activating a pump to circulate the stored hot water through a plate heat exchanger.

No G3 Requirement: As it functions as an open-vented thermal store instead of an unvented hot water cylinder, it is exempt from the stringent G3 building regulation requirements.

Pulsacoil A-Class

The Gledhill PulsaCoil A Class is an electric thermal store designed to deliver mains-pressure domestic hot water. It utilizes off-peak electricity (such as Economy 7) to heat water stored in an open-vented tank, allowing mains cold water to flow through a plate heat exchanger on demand instead of keeping pressurized hot water stored.

Key Features Safe Vented Design: This system operates at atmospheric pressure, which exempts it from the stringent G3 unvented cylinder regulations and eliminates the risk of explosion due to pressure accumulation. Sensor-Driven PCB: In contrast to older models (such as the PulsaCoil 2000) that relied on capillary thermostats, the A-Class employs electronic sensors governed by an internal printed circuit board (PCB) to regulate pump speed and heat transfer. Dual Immersion Setup:

It features a bottom off-peak immersion heater for daily bulk heating and an upper on-peak boost element for additional heating during the day.

Pulsacoil 2000

The Gledhill PulsaCoil 2000 is a widely recognized direct electric thermal store, specifically engineered to supply mains-pressure hot water. Enclosed within a rectangular metal casing, it heats water indirectly on demand by utilizing an off-peak electric supply, such as Economy 7, and channels incoming mains cold water through a plate heat exchanger.

Key System Features Mains Pressure Hot Water: Provides robust and consistent pressure at your taps without the necessity for safety discharge pipes, which are regulated by stringent G3 unvented cylinder standards. No Legionella Risk: Domestic hot water is not retained in a stagnant tank; instead, it is heated instantaneously as it flows through the heat exchanger.

Dual Immersion Setup: Incorporates a lower off-peak immersion heater for primary daily heating and an upper on-peak boost element for additional hot water when needed.
