Marine heating is a necessity if you want prolong your boating season or even if you just like your creature comforts.

Eberspacher heaters, recommended and installed by Tate & Crewe Marine, produce heat by mixing a fuel air mix inside a combustion chamber, which is the ignited by a glow pin this in turn heats the heat exchanger.

Fresh air is then drawn into the heater which passes over the heat exchanger; the warm air being distributed around the vessel via a network of ducting.

The temperature in the cabin is controlled via a bulkhead modulator and room sensor.   

Airtronic Heating Systems

Most common units fitted are the Airtronic range; these units come in various heat outputs of 2.2kw, 4kw, 5.5kw and 8kw for larger vessels.

Hydronic Heating Systems

The Hydronic range is a water heater which is flexible in its uses as it can be used as a heater using radiators or can be used to heat a calorifier to provide hot water for the vessel.

A control switch (1), or a 7 day timer, will start the heater operation. The heater’s motor will operate the fan (4) drawing in air for the combustion chamber (2) to mix with diesel. This is delivered by the remote factory set fuel metering pump (3). This draws the fuel for the heater from the tank.

A glow pin (5) ignites the fuel air mist and combustion is established. This heats the heat exchanger (6), and the products of the combustion (7) are passed out of the heater and on through flexible stainless steel tube to the exhaust outlet. The heater is not connected in any way to the engine.

The fresh air fan (8) draws in cold air for heating; quite separate from the combustion process. This air passes over the sealed, finned heat exchanger (6) and under pressure, passes through the duct work. This delivers the warm air which is automatically controlled to give your desired temperature.

All the components that go to make a full installation are purpose designed to work together reliably and withstand a tough environment.

This unit also comes in various heat outputs of 4.3kw, 5kw, 9.5kw, and16kw.

On starting the heater draws in combustion air (1) from the engine area or where the heater is located.

Fuel is drawn (2) from the tank and mixed with the combustion air.

A glow pin (3) ignites the mix and a controlled flame is established in the heat exchanger (4). The integrated water pump (5) now circulates the system’s water, passing it over the heat exchanger and onto the calorifier and radiator system (6).

Once the system is hot, the heater will regulate down to a lower heat level. This avoids unnecessary cycling and thus avoids wasteful repetition of the start cycle.

The heater in lower, or stepped output tops up the system to maintain optimum temperature.

Eberspacher products are renowned for their effectiveness and reliability, yet depend upon a careful and proper installation.

At Tate & Crewe Marine all installations are carried out with thought and care to the highest standards of safety, operational effectiveness and neatness.
