Hot Water Storage Systems (Thermal Stores, buffer and accumulator tanks)

Hot Water Storage Systems (Thermal Stores)

Here at Gondwana we have been designing, installing and supplying unique, high spec  thermal stores for over 15 years to the public, the trade and for our own projects.

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 make the most of the heat generated by a Solar System, Wood Heating System or Heat Pumps without a quality, correctly sized hot water storage systems.

We design, import, supply and install from 35 litres to 200,000 litres for the Uk market, that equates from a  wee shepherds hut  to a industrial building and everything in between.  If you need help with a project please don’t hesitate to get in touch!

Thermal Stores, Buffer Tanks and Accumulator Tanks

All hot water storage systems are basically thermal batteries (Thermal Stores). You charge them ( heat them up) using an array of potential heat generators, this could be gas, oil, mechanical biomass, wood burning stoves and pellet stoves , solar thermal, solar pv and heat pump technology.  This then allows you to use the stored thermal energy when you want.

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 / need one) as well as a coil for dhw we can also offer plate heat exchangers for dhw. This helps streamline the install by getting rid of a existing vented or unvented hot water cylinder and associated pipework, this improve over quality and efficiency of the whole system.

At Gondwana Green Heat we supply 2 main product ranges, off the shelf solutions in a range of materials , copper, stainless and cardon steel from the Uk and europe.  These tanks are great and offer cost effective versatile tanks with 100s of options in terms of size , shape and heat exchangers options.

We also offer and are better known for our custom hot water storage solutions, these again can be made of copper, stainless and carbon steel or a combination of materials.

The benefits of custom are huge, they allow you freedom to manufacture virtually anything to your exact requirements for any situation.

1. different shapes , tall and skinny, oval, squat and even cube tanks are possible
2. Custom insulation options, insulation for tanks is of paramount importance.  We do factory fitted options and detachable solutions that are fitted on site, we even do foam filled on site options.  From 50 mm to 300mm
3. Vented or pressurised tanks or a combination of both through heat exchangers.
4. Custom heat exchangers allowing you to separate parts of the system, extra long heat exchangers for maximum heat exchange. Solar thermal coils, heat pump coils, dhw coils
5. Immersion heaters for Pv / turbine input or simply direct electric dhw and wet central heating .
6. specialist heat pump thermal storage tanks with massive 32m long, 3/4 finned copper dhw coils and thats not the limit.

As well as Thermal storage tank we also supply a large range of components to compliment them.

1. Dtc controllers ( differential temperature controller) , these are used to control heat generators like gas, oil, solar thermal and heat pumps.  We also use them for the control of pumps in wood burning boiler stoves.
2. Loading valves with and without pump group
3. additional insulation layers, inc injection foam ( on site)
4. Stainless steel plate heat exchangers from 45kw to 600kw, these can be used to separate parts of systems or we commonly use them for dhw production along side tanks.
