HotHead

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.

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

Up to:

130°C

28bar

and is suitable for use with a number of glycol and antifreeze mixes commonly used in renewable technology applications.

HotHead hot water cylinders are manufactured to the same high quality standards as all of the other products in our range and, as with the rest of our products, fully customized HotHead cylinders can be made available on request. All of our products come with aftersales support.

Why Choose a Stratifying Cylinder?

25 year warranty icon

Decreases the start-up and recovery thermal response times of the installed system

Reduces stored energy losses

Compact Heat

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.
