Marine Calorifiers

What Is A Marine Calorifier?

A marine calorifier is a specialised hot water storage vessel designed specifically to suit the demands of boats and yachts. 

What Types of Marine Calorifiers Are Available?

Although most marine calorifiers are normally specified as unvented, the actual design can be changed to accommodate the unique requirements of your project:

  • Vented or Unvented
  • Horizontal or Vertical
  • Polyurethane Foam Lagging Insulation or Rockwool
  • Insulation with a galvanised steel or aluminium case
  • Single Copper Coil or Double Copper Coil
  • Marine Immersion Heater

Flexible with the dimensions and sizes, McDonald Engineers provide a bespoke service dependent on your requirements. Regardless of the specification, we will ensure that the unit is simple to install and, if required, can supply the boat water heater in sections for erection on site.

Why Copper For Marine Calorifiers?

The growth in demand for Copper calorifiers is largely thanks to coppers’ enhanced thermal conductivity, as well as its excellent non-corrosive and anti-bacterial qualities. These are proven to be more effective at eradicating germs such as MRSA, E-coli and Legionella. However, there is the option to add a destratification pump to circulate the water and further reduce the risk of Legionella.

We manufacture to BS 853, 1566 and 699 and hold two Kitemark licences for copper cylinders. A BSI approved quality plan to ISO 9002 is followed and each Calorifier is rigorously tested to ensure problem free installation and operation.
