Because the way many renewable heating systems work, eg wood, solar, heat pumps etc there is not a instant heat created, heat takes time to be created. A log / pellet / chip boiler does not simply create kw’s of energy instantaneously it takes time to get going unlike gas and oil boilers which are virtually instantaneous. In a similar way solar heated tanks rely on the sun to charge them, however in the uk we cant guarantee when the sun may come out. This is where hot water storage systems come in, they ensure you have heat when you need it
Domestic hot water, coils, tank in a tank, and heat exchanger
Thermal stores contain a way to produce DHW (hot water to the taps) this can vary in its method,
system link ups different technologies heating the same space
Thermal storage systems also have the benefit of allowing us heat a property with a arrangement of heating technologies, for example Gondwana Green Heat does lots of wood burning boiler stoves many people want to link this to there existing gas or oil central heating. This is easily done with a small thermal store, e.g. 210 250 liter thermal store. Both heat sources are plumbed into the thermal storage tank, allowing the wood burning boiler stove to heat the tank when its in use, all other periods the gas or oil central heating boiler satisfy’s the thermal storage system.
The options are endless for thermal storage systems and there configurations, we could write a book on it easily, however I’m not sure it would be a best seller.
Gondwana Green Heat retails, imports and designs are vast array of hot water systems for our own projects as well as the general public, industry professionals and the trade. If you need help with a project please don’t hesitate to get in touch, we now also sell a range of thermal storage tanks in our web shop. Please have a look.
