What is a Thermal Store?
A thermal store is a hot water cylinder that acts as a heat reservoir for domestic use and heating systems. Unlike traditional cylinders, the water inside the thermal store is not consumed directly. Instead, mains pressure cold water flows through a high-efficiency heat exchanger coil within the store, where it is heated by the surrounding hot water. This process delivers instant, high-pressure hot water without needing an unvented system.
Thermal stores are highly efficient, offering shorter recovery times and compatibility with multiple heat sources, such as stoves, boilers, solar panels, and heat pumps. Additionally, they can supply heat to various systems, including underfloor heating and radiators.

The 300 Litre Thermal Store offers a cost-effective, efficient, and environmentally friendly solution for domestic hot water and heating needs. Its open vented design, large capacity, and ability to integrate multiple heat sources make it a standout choice for modern homes. Whether you’re connecting a stove with a back boiler or combining several heating systems, this thermal store delivers exceptional performance and long-term reliability.
