Thermal store cylinders provide mains pressure hot water for baths and showers as well as acting as a heating buffer to allow the integration of multiple heat sources into a single heating and hot water system.

Features and Benefits

  • Integrate multiple heat sources
  • Provides mains pressure hot water
  • Dedicated heating system buffer
  • Simplified installation and conrol

Why use a thermal store?

Alternative heat sources such as solar thermal and wood burning stoves are typically uncontrollable sources of heat, often providing more than enough to meet requirements when they are active but operating intermittantly, meaning they can be inactive when there is a demand for heat or active when there is no heat demand. Thermal store cylinders help solve this issue by safely storing heat as it is generated, allowing it to be used for space heating and/or mains pressure hot water production later on.

In addition to storing heat from intermittant heat sources, thermal store cylinders also simplify the connection of multiple heat sources to your heating system, making it easier to install, configure and operate.

Heat source options

Thermal stores with underfloor heating

Whilst they can be used with radiator systems, thermal stores are particularly useful when connected to an underfloor heating system. Their heating buffer allows the small, infrequent heat demands of a house that is up to temperature to be met without turning the main boiler or heat pump on intermittantly to provide small amounts of heat. This reduces waseful on/off cycling of the heat source for reduced running costs and increased lifespan.

Our thermal store systems

Chelmer have over 15 years experience designing thermal store cylinders. We’ve used this expertise to produce our latest range of Ecocat thermal store cylinders, designed from the ground up to integrate boilers, heat pumps, solar thermal and wood burning stoves.

For larger integrated systems, our dual cylinder systems combine a thermal buffer store with a mains pressure hot water cylinder for increased storage capacity.
