Hot Water Storage Systems (Thermal Stores)

Hot Water Storage Systems (Thermal Stores)

As well as creating heat through your stove – or gathering it for free with your solar array, you will probably want to store some heat for times when the stove isn’t burning or the sun isn’t shining.

Hot water storage systems, also know as Thermal Stores, Accumulator Tanks and Buffer Tanks, are at the heart of Gondwana Green Heat’s business. You simply can’t have a Solar System, Wood Heating System or Heat Pump without a Thermal Store, Accumulator Tank or Buffer Tanks Storage Systems. We supply Thermal Stores from 100 litres to 200,000 litres. 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!

Thermal Stores, Buffer Tanks and Accumulator Tanks:
What’s the difference between them and which one do I need?

All hot water storage systems are basically batteries (Thermal Stores). You charge them with hot water and store the hot water for when you need it. You can use hot water storage systems with all heat sources, and they also enable properties with multiple heat sources to connect them together reliably and efficiently. For example, if you have a existing gas or oil boiler but want to have Solar Thermal and a Boiler Stove, we can design and install all heat sources into one Thermal Store. While at the same time offering you a DHW coil in the Thermal Store (if you want one). This helps streamline the install, improve quality and efficiency of the whole system.

At Gondwana Green Heat, we can help you calculate how big a Thermal Store you need, and recommend the best options for your property.
