Marine Calorifiers - Direct and Indirect unvented hot water cylinders


Hot water vessels manufactured to marine specification (also known as Calorifiers) are available in a particularly wide range of configurations in order to meet a variety of needs from the marine industry.

Vertical or Horizontal, single and twin coil Calorifiers

Marine Calorifiers can be manufactured to either a vertical or horizontal pattern and factory insulated. Marine cylinders can be made with single or twin heat exchangers to accommodate more than one heat source if available (e.g. engine, solid fuel, gas boiler, etc).

Custom and bespoke Calorifier design service

Marine Calorifiers can be manufactured with connections positioned as and where you want them affording amazing flexibility to the boat designer and simplicity to the fitter. This feature can be of particular importance when retrofitting, if space is at a premium or confined access makes positioning difficult.

 

Hot water cylinders built to cope with a harsh corrosive marine environment

In the aggressive salt water environment in which these vessels have to operate copper is arguably the best material from which to manufacture. The common belief that stainless steel doesn't rust is actually inaccurate. But the choice is yours. The price table below relates to Calorifiers made from copper. Stainless Steel marine Calorifiers are available by request.

Longer life Marine Calorifiers from superior build quality

Calorifiers specified on the table below are manufactured from a heavy gauge of copper to withstand a working pressure of up to 3 bar. This is suitable for most marine applications but even higher specification is available where higher operating pressures are required.

We can also offer you stainless steel Calorifiers if preferred. Simply call with your product specifications or requirements.
