Sailboat and Motorboat Heaters

Keep warm on the water

One of the finest pleasures in life can be owning a boat. But sometimes these pleasures can be spoilt by bad or inefficient heater systems. At MV Heating we can vastly improve these problems with just a simple installation of one of our many heaters and kits. The question is: what sort of heater are you looking for?

For crafts that require a hot water system then theMV Hydro range is the way to go. All our Hydro models are diesel powered and can supply heating through radiators or matrix heaters to heat up the cabin, or via calorifiers for domestic hot water. They have very low servicing costs due to modular construction and simple wiring means a variety of controls are available to operate the heaters.

For smaller vessels that only require hot air heating, then our Airo series is perfect for the job. They’re easy to install with low running costs and provide the cabin with warm, dry air whenever you need it. All size craft can be catered for too, as our air heaters range from 2kW to 5kW, for extra air flow! Accessories are available to help customise your needs and the comprehensive kits we supply, insure that every size vessel can be catered for. If it’s noise you’re worried about, we also supply silencers for the exhaust and combustion air intake, as well as acoustic ducting to dampen as much noise as possible.

Typical Boat Heater Installations

Water Heating System

The diagram gives an example of what can be achieved with a hot water system. A hot water system has more control than an air heating system and can also provide hot water for the galley and showers via a calorifier. The addition of screen demisting via high air flow matrix heaters is a great safety feature. The MV Hydro water heater systems create a real central heating feel in your boat driving out mould and condensation. You can use radiators, towel rails, matrix heaters in any combination all with individual thermostatic control if required.

Air Heating System

A simple installation on a small sailboat under 9 meters would consist of an Airo 2kw with 2 outlets, one in the saloon and the other in a berth. For larger sailboats we go to the Airo 5kw heater which will power up to 4 outlets. If you require more outlets we go to the kits which have 2 x Airo 5kw Heaters with up to 8 outlets. In this case one heater is used to heat the aft of the boat plus saloon and the second heater to heat the forward half of the boat plus saloon.
