McDonald Thermal Stores

What is an Thermal Store?

Thermal stores provide the perfect solution for combining heat sources to maximise energy efficiency and delivering water and space heating.

Can use different fuel sources

Purpose-built thermal stores are designed and sized to take inputs from a number of different heat sources.

Off-grid solution

One area where thermal stores can be a particularly innovative solution is in off-grid properties with multiple heat sources, including electricity.

Easy to install

A thermal store can be situated virtually anywhere within the home as long as the header tank is higher than the radiators. 

Requires minimal maintenance

There is no need for discharge pipework and virtually zero maintenance which makes them a great option for flats and retirement living.

Thermal Stores

The energy produced from solar thermal can also be used to heat water via a thermal store. The thermal store utilises a high-efficiency solar coil to allow the homeowner to benefit from natural solar energy produced during the day. Once the solar energy available is insufficient to heat the store, it will revert to a conventional boiler as its primary heat source. 


The central heating circuit can be supplied directly from a sealed system boiler although an auxiliary heating circuit can be connected from the store in which case the solar will also provide an input to the auxiliary heating circuit.
