THE HEATER
The Thermotop Marine Kit incorporates a
diesel powered 5.2kW / 4.2kw water heater,
with a capability of a variable heat output,
down to a reduced heat level of 2.5kW.
Heated water is supplied to the vessel's
heating system, consisting of household style
radiators and an option of domestic hot water
is also possible with the use of a Calorifier.
The heater burns diesel fuel supplied from the
vessel's main tank, the correct amount of fuel
being measured and drawn by the dosing
pump, prior to delivery to the heater's
combustion chamber.
On arrival in the combustion chamber, the fuel
is vaporised off a unique 'Ferro-Tech' burner,
initially being ignited by a glowpin. Following
starting the heater, combustion is sustained by
the continuous vaporisation of the metered
fuel delivery.
Combustion takes place within a sealed heat
exchanger, and exhaust gasses are ducted to
the vessel's side or transom, via a stainless
steel flexible pipe and skin fitting.
Meanwhile the heater's integral water pump
circulates cool water from the heating system
into the heat exchanger, where it is heated
and re-introduced hot into the heating system
to heat the radiators etc.

Operation of the heater is via a 3 event digital
timer, which can be sited in the main cabin
area. The timer also has an "instant heat"
facility.
If blower boxes are used, an optional thermostat
control system is available to regulate the cabin
temperature.
For maximum safety, the heater has various
sensors which will shut down the heater should
they be activated.
These heaters are not solely used in boats; but
are supported by a pedigree of military, truck,
car, luxury coach and a variety of other applica-
tions.
The Thermotop C / E marine kit is designed
specifically for marine users, incorporating the
high technical specification required for The
Inland Waterways
