Thermal store mains pressure hot water system
Our CUBEflow thermal store range is specifically designed for installations into restricted spaces, providing a high performance, mains pressure hot water solution which delivers enormous benefits.
With the rectangular design of the store, it takes up to 27% less space than an equivalent volume cylinder, freeing up space for other uses.
Our thermal store approach can suit multiple installation applications, including electric, boiler or central plant inputs to meet hot water demand. With our unique design, manufacturing and space saving solution, we can offer significant cost savings both during installation and ongoing running costs.
The CUBEflow rectangular, copper hot water tank is also the perfect like for like replacement for original Elson hot water tanks Coral E and Coral Si.

Direct Thermal Store Compatible With Open Vented Boiler
Replacement for Elson Coral E
A floor standing Thermal Store Mains Pressure System:
- Vented and heated by immersion heaters or open vented boiler to high temperature
- Hot water for taps, comes directly from the mains passing through a specially designed heat exchanger and drawing heat from the surrounding thermal store of water. This water then passes through a thermostatic mixing valve, which blends it to the correct temperature for the taps
- Can be fitted anywhere in the home
- Suitable for use with an open vented boiler and/or off peak electricity tariffs
Additional options include:
- Washing Machine Frame
Indirect Thermal Store Compatible With Sealed System and Central Plant Boilers
Replacement for Elson Coral Si
A floor standing Thermal Store Mains Pressure System:
- Vented and heated by a sealed or central plant boiler and/or off-peak electricity to high temperature
- Hot water for taps, comes directly from the mains passing through a specially designed heat exchanger and drawing heat from the surrounding thermal store of water. This water then passes through a thermostatic mixing valve, which blends it to the correct temperature for the taps
- Can be fitted anywhere in the home
- Suitable for use with a sealed system or central plant boiler and/or off peak electricity tariffs
Additional options include:
- Washing Machine Frame
Open vented Elson replacement products
Whilst the thermal store Elson replacement products are manufactured under the CUBEflow brand, we also manufacture the complete range of open vented Elson products under our ELSOflow brand. Click here to see the relevant product page.
A standard range of rectangular copper, hot water tanks and cylinders are available – for a guide to sizing and dimensions simply visit our sizing page.
In addition, we also manufacture bespoke tanks and hot water cylinders and can provide advice on sizing, design and a survey service if required.
To discuss your options, including Elson water heater replacements, contact us on 01592 611123 or contact us online.
Our focus is very much on the manufacture of copper hot water cylinders and tanks. Copper provides fantastic benefits including;
- Ability to kill 99% of bacteria including Ecoli and legionella
- One of the most efficient conductors of heat
- Significantly more flexible for manufacturing than other materials
- Long lifespan due to its amazing resistance to corrosion
- 100% recyclable

Can the CUBEflow be used as an Elson replacement?
The CUBEflow Coral E model provides a replacement upgrade for the discontinued Elson Coral E, and the CUBEflow Coral Si replaces the original Elson Coral Si models.
The major benefit for both is that the CUBEflow provides mains pressure hot water, upgrading the original Elson performance.
Is the CUBEflow thermal store vented or pressurised?
The CUBEflow is an open vented cylinder therefore not pressurised. When the water held inside the store heats up, it will expand, however the expansion is accommodated in the feed and expansion tank located at the top of the unit.
Do I need to have the CUBEflow serviced annually like a gas boiler or unvented cylinder?
As the CUBEflow thermal store is open vented, it does not require an annual safety check or service.
The mains pressure hot water from the CUBEflow is delivered via the internal coil and the temperature is controlled by the blending valve, preventing any risk of scalding.
As the unvented cylinder is a pressurised cylinder, there are essential annual safety checks to be carried out to ensure the safety of the product.
How many electrical feeds are required for the CUBEflow Coral E?
The CUBEflow Coral E requires two electrical connections to the immersion heaters, ideally one off peak and one on peak.
As the CUBEflow is designed to deliver mains pressure hot water without the need for additional pumps, pcb’s or flow sensors. Other manufacturers thermal stores require a third electrical supply to power the additional components they utilise.
Can I use the CUBEflow thermal store for central heating?
Yes, the CUBEflow can provide heat to the central heating system, subject to sufficient heat input. This can either be an open vented system, circulating the water from the cylinder round the central heating system or s sealed heating system via in internal heat exchanger.
Are the CUBEflow products bespoke designed?
The CUBEflow is available with standard tapping configurations, however we appreciate these layouts do not suit all applications.
Therefore all CUBEflow products can be bespoke designed to suit the installation requirements, whether it is due to space restrictions or simply moving tappings to reduce installation time and costs.
