For twenty years we have been manufacturing both standard and bespoke hot water systems, combining just about every type of heat source there is available to drive central heating and hot water for domestic properties. The Xcel HEATBANK® standardises the whole approach, providing design features that allow any possible combination to be made using a standardised product.
In its most basic form the thermal store can act as a buffer system, used purely for central heating. Large 1½” bosses allow the largest of domestic wood burners to be comfortably connected using gravity circulation, with numerous other bosses for pumped circuits. Even larger 2¼” bosses provide for immersion heaters as well as retro-fit coils (mainly used for overheat protection). A large 1m² coil is provided as standard for connection of solar panels (or any other pressurised heat source).
One can then add the PHE (plate heat exchanger) option to generate mains pressure hot water to run multiple bathrooms using high pressure mains water, without the need for unvented certification or annual maintenance.
Further options provide fitted controls for the use of boilers of all types (sealed and vented) as well as heat pumps. Control options include pump assemblies, thermostats, programmers and timers,and control valves.
Both radiators and underfloor heating can be run simultaneously, and the thermal store is configured in such a way that low temperature loads (e.g. underfloor heating) can run off low temperature heat sources (e.g. heat pump) while high temperature loads (e.g. radiators) run using higher temperature heat sources (e.g. wood burners or boilers)
