MV Hydro 5 12V Marine/Boat Heater Kit - A good replacement for the older Mikuni MX40
Featuring a New Brushless DC Motor!
The MV Hydro 5 is a powerful 5kW modulating diesel-fired water heater designed to deliver hot water for heating purposes through radiators or matrix heaters, and for domestic use via a calorifier. It operates fully automatically with low-energy glow pin ignition and microprocessor control for precise temperature regulation.
This heater comes pre-assembled on a stainless steel bracket with anti-vibration mounts, making installation straightforward. The water pump is also pre-assembled and pre-wired on the bracket for added convenience. The kit includes an exhaust pipe with a built-in silencer and silicone-coated lagging, ensuring low noise levels on the pontoon and reduced exhaust temperatures in the boat.
The modular construction results in very low servicing costs, and the straightforward wiring system allows for various control options to operate the heater.
Kit Includes:
This kit includes everything necessary for installation, excluding plumbing to the radiators and calorifier.
This is a genuine MV product with a 3-year warranty. In the unlikely event of a fault due to defective parts or workmanship, please return the heater to Mellor Online or MV UK for assistance.
