Duplex stainless steel, open vented and sealed system thermal stores for combining multiple heat sources in a variety of configurations.
Grant ThermaWave Thermal Stores
With rising fuel prices, it is now more important than ever to look for ways to lower home heating costs and save energy. Many people are opting for renewable technologies to heat their homes; however, finding a way of combining several renewable technologies with traditional heating systems has proved very difficult, until now.
Thermal stores allow multiple heat sources to be connected in a number of different ways, with immersion heater(s) back-up. This makes it possible to have a gas or oil fired boiler connected to a solid fuel appliance and also a renewable heat source such as solar thermal or a heat pump. Furthermore, underfloor heating system manifolds as well as radiator circuits can also be directly connected to the store.
Grant ThermaWave stores
The Grant ThermaWave is available in three variations:
- open-vented with solar coil
- open-vented with solar and DHW coils
- sealed system with solar and DHW coils.
Sizes range from 250-500 litres.
ThermaWave DHW stores have been designed for situations where there is a greater demand for domestic hot water. The addition of the DHW coil means there is no need to link the store to an additional cylinder, resulting in a more cost effective and compact installation. If using a standard ThermaWave without the DHW coil, a separate domestic hot water kit (product code: GTHERM/KIT1) is also available for those situations where a hot water supply is required.
A sealed system kit is available to complement existing sealed system products e.g. oil or biomass boiler. Please note, uncontrolled heat sources like solid fuel log burners, must not be used with a sealed system thermal store or unvented cylinder.
The store has been designed in such a way that it slows inlet water velocities, ensuring multi-level temperature distribution. High specification 1mm thick duplex 2304 stainless steel is utilised which resists all forms of corrosion. Compression fittings on most connections dramatically reduces fitting time for the installer and 40mm injected polyurethane foam insulation gives an exceptionally low standing heat loss, making the units highly efficient.
