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.
Electrastore Smart Thermal Store.
Electric boiler with thermal storage flexibility
Eectrastore is a market first electric boiler incorporating thermal storage, which is designed to maximise the benefit of time of use tariffs, via our innovative IOT control system with self learning algorithm, to store energy when it’s provided at low cost and low carbon, so it can be used when it is needed.
The ELECTRAstore is powered by Backer technology and long life immersion elements. The range can provide either mains pressure hot water and primary hot water to heat standard “wet” radiators or mains pressure hot water only.
Unlike electric combination boilers, the ELECTRAstore thermal store is designed to utilise either standard, off peak or time of use electricity tariffs, allowing homeowners to raise the temperature of the store to as high as 90 degrees during low cost tariff periods, reducing ongoing running costs.

There are many products on the market that can be utilised with either standard or off-peak electricity, however the ELECTRAstore goes one step further by being able to also detect low rate tariff periods when available.
With Backer technology in conjunction with McDonald Water Storage manufacturing expertise, the ELECTRAstore can maximise the benefit of lower electricity rates to improve efficiency and keep your electricity bills to a minimum.
When wind and solar generation are at their peak, not only is wholesale electricity costs are at their lowest, but also carbon intensity reduced, making it the best possible time to store energy at home, for use at other times during the day.
