Joule Stratification Thermal Store

The Joule stratification thermal store utilises an open vented boiler and / or direct electric immersion heaters as its primary energy source. It comes fitted with tappings for a wood burning or solid fuel boiler as standard, which can be blanked off if not required at the time of installation. 

Advances in Efficiency

One of the benefits of the open vented boiler configuration is that the whole output of the boiler is available to the thermal store. This will provide an improvement in the operational efficiency of the boiler, reducing the primary energy usage and running costs. Hot water and heating 

Pressurised Hot Water

The Joule stratification thermal store provides high-performance mains pressure hot water. This cylinder is the only way to safely integrate an open vented solid fuel system into your pressurised hot water system.


Rapid Heat Up of Heating System

The heat energy provided from the primary heat source and / or solid fuel input is circulated from the store to the central heating circuit, allowing rapid heat-up of a radiator system. 


Electric Only Option Suitable for Apartments & Turbines

Electric-only option In  situations where no gas or solid fuel source is available the  Joule stratification thermal store can be used exclusively from the two  3kW electric immersion elements which will provide both hot  water and heating for the property. The obvious application is apartments where no gas main is available but this could also be appropriate where electricity is available from a renewable or low carbon source. If connected to the standard grid then the thermal store is the perfect solution to maximise usage of an off peak tariff where arrangements should be made to power the lower immersion element in order to minimise the running costs. 


Numerous Heat Sources

A number of heat sources can be integrated into the thermal store. This makes combining heat sources very easy and ensures that all energy sources are used efficiently. Sealed boilers can be integrated with open vented solid fuel boilers through the use of an internal coil. It is necessary to specify when ordering. 

Numerous Heating Zones

A number of heating zones can be taken from the thermal store. By using an external heat exchanger sealed heating systems such as underfloor heating can be connected to open vented boilers such as a solid fuel stove.
