Traditional With A Twist
HotHead hot water cylinders combine a traditional approach to hot water storage with an innovative new internal heat exchanger (patent pending) designed to encourage thermal stratification in the stored water, providing the user with a faster response to their hot water demands.
The funnelled heat exchanger transfers the heat supplied to hot water cylinders through a highly efficient finned coil to a reduced volume of water, delivering fast hot water by increasing its temperature faster before encouraging it to rise away from, and drawing cooler water into, the heat exchange area by using the natural difference in buoyancy between hot and cold water.
How does the HotHead® work?
The funnelled heat exchanger transfers the heat supplied to hot water cylinder through a highly efficient finned coil to a reduced volume of water.
The HotHead is capable of delivering fast hot water by increasing its temperature rapidly before encouraging the hot water to rise away from the heat exchange area. The natural difference in buoyancy between hot and cold water means cold water is drawn into the heat exchange area as the hot water rises ensuring a continuous flow of hot water.
The funnel then guides the water directly to where it can be extracted by the consumer and prevents it from being cooled down through mixing with the rest of the water in the cylinder.
The high efficiency heat exchanger coil tubing used in our hot water cylinders has been certified.
and is suitable for use with a number of glycol and antifreeze mixes commonly used in renewable technology applications.
Why Choose a Stratifying Cylinder?
Supplied vented or unvented
Decreases the start-up and recovery thermal response times of the installed system
Reduces stored energy losses
The heat exchanger inlet temperature is kept as low as possible, increasing the efficiency of the system
Why Choose Copper?
Recycled copper meets 42% of the European copper demand, using only 15% of the energy required in extracting new raw materials, making it sustainable, environmentally friendly and the most recycled plumbing material available today.
Copper also has a long and established history of being used in conveying clean, safe drinking water because of its natural antibacterial properties and inherent health benefits making it a well trusted, tried and tested material for water supply and storage. The presence of copper ions destroy potential Legionella harbouring bacteria responsible for Legionnaires’ disease, making your water clean and safe to drink.

Copper is a well-known, trusted, corrosion resistant. With great benefits.
