 Water Heater WHTxx

1  Introduction

The tap water in the boiler’s tank will be heated by one of the follow-
ing heat sources:

 - Engine coolant flowing through one of the heating coils.

 - CH water from the ship’s heating system flowing through the sec-

ond heating coil,

 - The built-in electrical heating element.

2  Use

Proceed as follows before using the calorifier for the first time.

•  Clean the inside of both the tank and heating coils by rinsing 

them with clean tap water.

•  Open the stop cock in the water pipe between pump and tank. 

Open the hot water tap to release air from the tank and it fills with 
water.

•  Fill the heating coils from the engine’s cooling system and the 

ship’s heating system respectively.

•  Bleed air from the outer tank if this is mounted vertically. ‘E’ is the 

outer tank air bleed valve.

•  Check all connections, pipes and fittings for leaks.

  c

aution

In the event of a leak, stop the engine immediately or switch off 
the ship’s heating system and repair the leak before restarting 
the engine or switching on the heating system.

•  Stop the engine and check the coolant level. Top up if necessary.

•  Check the liquid level of the heating system and top up if neces-

sary.

•  The calorifier is now ready for use.

2.1  Heating with engine heat

The engine has to run for a certain time before the tap water heats 
up. The time required depends on the size of the calorifier and the 
size of the engine.

The hot tap water can be very hot, temperatures up to 80˚C 
(176˚F) are possible!
For safe use, always mix with cold water.

2.2  Heating while the engine is idle

When the engine is idle, the water can be brought to and maintained 
at the desired temperature through the ship’s heating system or the 
electrical heating element.
Heating tap water in the boiler tank in this manner usually takes con-
siderably more time than by using the heat of the engine.

  i

nformation

The amount of heat created by an internal combustion engine, 
and thus available for heating the calorifier, is about the same as 
the engine power output. So an engine which delivers 50 kW at 
the shaft will also provide about 50 kW of heat! Generally speak-
ing, a ship’s heating system has a substantially smaller heat ca-
pacity and an electrical heating element is only 1.5 kW or less.

  W

arning

!

Never switch on the electric heating element if the calorifier 
tank is not completely filled with tap water.

3  Preparation for Winter

The water should always be drained from the calorifier. To do this, re-
move the hose connections ‘C’ and ‘D’ and both plugs from the non-
return valve ‘3-F’. Open the tap so that the pipes and calorifier tank 
drain completely.

The heating spiral does not require draining. 

4  Installation

4.1  General

First consult the piping diagrams and installation drawing, see draw-
ing on pages 14 through 17.

Preferably fit the boiler low in the ship so that 

highest

 point of the 

boiler is at a 

lower

 level than the expansion tank of the ship’s engine. 

This is in connection with removing air from the system, see draw-
ings 1. 
The engine can be connected to the heating coil via connections ‘A1’ 
and ‘B1’ or connections ‘A2’ and ‘B2’.
The heating coils are identical.
The flow direction of the engine coolant through the coils has no im-
pact on their correct operation.

If the boiler does have to be positioned 

above

 the level of the expan-

sion tank for the engine an additional expansion tank must be fitted, 
see drawing 2. 
Fit a shut-off valve between the expansion tank and the highest 
placed pipe between the engine and the boiler. This shut-off valve is 
closed during normal operation and only opened when topping up 
or bleeding the system. 

If the calorifier is installed 

considerably lower

 than then the engine’s 

expansion tank, the coolant water can start to circulate when the en-
gine has stopped. This will lead to very fast cooling of the hot tap 
water. To prevent this, install a non-return valve - see drawing 3. A 
stop cock can also be used instead of a non-return valve.

The resistance in the pipe can become too high if the pipes between 
the engine and the boiler are extremely long. The cooling fluid will 
then no longer circulate through the boiler. In that case fit a central 
heating circulation pump in the pipe, see drawing 4.
