A WrightChoice Heat Store is created when you retrofit one of our unique micro 12 volt, 3 watt pumps to your existing hot water cylinder. Using one of our unique WrightChoice micro pumps and an innovative solution you will store four times more energy in an existing standard cylinder. A single top mounted existing immersion heater and you can heat 100% of the hot water cylinder instead of just the top third.
The solution is so simple it can be installed as a do it yourself solution costing under £60 in materials and it could take you less than one hour to fit. Read this review to understand why you should create a thermal store. See how you create a heat store – Click This Link.
Hot Water Cylinders compared with a WrightChoice Heat Store
In a typical 4 bedroom house with a typical 180 litre hot water cylinder, a conventional hot water cylinder will store 2.4 Kw/Hr of energy, That’s enough hot water for 1.6 showers (60p per shower using peak rate electricity)
In a typical 4 bedroom house with a typical 180 litre hot water cylinder, a conventional hot water cylinder will store 10.5 Kw/Hr of energy, That’s enough hot water for 7 showers (12p per shower using off-peak rate electricity)
Saved hot water avoids the use of energy to heat hot water when power (electricity) is expensive. Cheap or free electricity can be used in substitution for peak power usage when there is no cheap or surplus energy. Thermal Stores provide the perfect solution for combining heat sources to maximise energy efficiency, and a perfect solution for storing surplus energy during the day or night. WrightChoice Heat Stores are more efficient than a top of the range heat stores costing £1,500, but at a cost of £60 if you use your existing hot water cylinder.
You can modify any existing hot water cylinder into an amazing heat store with one of two WrightChoice Tank Devices.
A WrightChoice thermal store works at mains pressure or in gravity systems and it stores hot water until it’s needed.
This works in the same way as a conventional hot water cylinder as the stored water is fed to the taps directly from the thermal store.
The stored hot water is available for immediate use.
They are unlike conventional thermal stores which rely on flat-plate heat exchangers. Not only are the heat stores currently sold very expensive to buy and expensive to install, the cost of the energy needed to heat the hot water is four times the cost of a WrightChoice Heat Store.
Will it work and why have I not heard of this before?
The concept and performance of the WrightChoice heat store was validated by advanced computational modelling carried out by the University of East Anglia in 2025 and yes – it was proven that it outperforms current heat stores on the market. This is a disruptive product which benefits the customer only which means it is strongly opposed by manufacturers of thermal heat stores and heat pump manufacturers who sell new tanks and systems. Organisations set up to assist with de-carbonisation, including Councils, work closely with existing industry influencers.
Will it improve my current hot water and heating system?
A WrightChoice Thermal Store will reduce the cost of running a heat pump or a gas boiler.
Boilers and Heat Pumps can be turned off in the summer which means cheaper hot water and the life of a boiler or a heat pump is increased.
A WrightChoice thermal store will typically store energy from:-
Surplus electricity from the customers own photo voltaic solar panels.
Cheap overnight electricity
Hot water from a customers own solar thermal solar panels
