The Thermocube is a unit designed for maximum storage capacity in mind. It is perfectly suited to fit in an airing cupboard of other restricted spaces. Standard units are typically a cylindrical shape as the structural strength allows it to withstand mains pressure water, however because the Thermocube uses a hot water pack then a cuboid shape can be used which allows for significantly more water storage space.

Key Store Feature


• Ideal for property with space restrictions

• Ideal for single floor occupancy (FE version)

• Manufactured in stainless steel to reduce risk of corrosion

• Insulation depth of 50mm or 75mm available (100mm please enquire)

• Pre-plumbed hot water module

• Pre plumbed, integral feed & expansion tank (FE model only)

• Internal Diffuser tube reducing de-stratification

• Size range from 140 to 300 Litres

• Metal cased finish

• Bespoke sizes if required

• Manufactured in the UK



One of the main benefits of the Thermocube is that it is the additional water storage space compared to a typical cylindrical cylinder. A Thermocube unit can provide up to 40% more hot water than a cylindrical unit in the same size space.


Wood Burner


Heat Pump

The Thermocube works with a variety of different heating inputs including;

Whilst the main benefit is to draw off potable water for showers and taps, the unit can be designed to also allow for multiple heating inputs, just like a buffer vessel. Heating inputs can be from a variety of heating sources such as:


• Mains electricity (via immersion heaters)

• Solar PV panels (via immersion heaters)

• Solar Thermal panels

• A vented or sealed system boiler

• A biomass boiler

• A solid fuel appliance (such as a multi fuel stove)

• A ground/ air/ water source heat pump (additional top up by another appliance would usually be necessary in this case).


There is also the option of incorporating heat output connections, which can be used for providing heat to radiator circuits, towel rails, or underfloor heating systems.


Hot Water Controller

Key Hot Water Module Features


• Mains pressure hot water

• A hot water draw off rate of up to 30 litres per minute

• HW temperature can be adjusted up to 65˚C

• HW module can be mounted directly onto the store or mounted remotely and piped to the store

• Insulated heat exchanger and cover

• Stainless steel heat exchanger which ensures that the product life expectancy is optimal

• An ‘A Rated’ Wilo pump

• Simple fused spur wiring and it’s ready to go

• Store temperature can be 60˚C, reducing the heat loss (Compared to traditional store temperature of 75˚C)

• Hot water secondary return available

• Easy to understand controls

• Supplied with isolating valves

• Additional hot water modules can be added to create a ‘cascade’ effect, allowing for improved flow rates. Please see our Aquinox MF range for information.


Another benefit in the hot water module is the option to add numerous modules in a cascade; Please see our Aquinox MF range for information.

Unit Performance Test


This test was carried out on a 190 litre thermalstore, with:


• a 70kW Hot Water module

• a maximum store temperature of 67˚C

• the draw off temperature set to approximately 45˚C

• a continuous flow rate of 10.3 litres per minute resulting in a total draw off volume of 196 litres.

• A test period of 19 minutes.


Higher temperature and flow rates are achievable, but will be dependent on tank temperatures and volumes.


The result of this test shows that much longer draw off times are achievable with the Aquinox MF Range tanks than with a traditional thermalstore unit with a coil arrangement.
