• Correct installation of this heater is necessary to ensure
safe and proper operation.
Read and understand this manual before attempting to
install the heater. Failure to follow all these instructions
could cause serious or fatal injury.
• Heater must be turned off while re-fueling.
• Do not install heater in enclosed areas where combustible fumes may be present.
• Do not install heaters in engine compartments of gasoline powered boats.
• Install the exhaust system so it will maintain a minimum
distance of 50mm (2”) from any flammable or heat sensitive material.
• Ensure that the fuel system is intact and there are no leaks.
• Route the heater exhaust so that exhaust fumes cannot
enter any passenger compartments.
• If running exhaust components through an enclosed
compartment, ensure that it is vented to the outside.
• The use of Espar coolant heaters requires that the
coolant in the system to be heated contains a proper
mixture of water and antifreeze to prevent coolant from
freezing or slushing.
• If the coolant becomes slushy or frozen, the heater’s
coolant pump cannot move the coolant causing a blockage of the circulating system. Once this occurs, pressure
will build up rapidly in the heater and the coolant hose
will either burst or blow off at the connection point to the
heater.
• This situation could cause engine damage and/or personal injury. Extreme care should be taken to ensure a
proper mixture of water and antifreeze is used in the
coolant system.
• Refer to the engine manufacturer’s or coolant manufacturer’s recommendations for your specific requirements.

Quality engineered to provide a dependable means of heating,
the Espar Hydronic 10 is a diesel fired coolant heater capable of
between 1.5 kW to 9.5 kW/hr (5,100 to 32,400 BTU/hr). The
heater can be purchased either in a weather resistant box to protect it from the elements and provide for ease of installation or in
the universal form.
This light weight and compact coolant heater offers an affordable
heating solution to many applications. The Hydronic 10 is ideal
for pre-heating the engines of class 7 and 8 trucks, off-road
equipment, buses, boats and in Fuel + Hydraulics in conjunction
with appropriate heat exchangers.
The heater pumps coolant from the engine, heats it and returns it
to the engine. It features automatic heat regulation while being
fuel and power efficient. Since the heater runs on diesel fuel and
12 or 24 volt power, it is able to perform this completely independently of the vehicle engine. A temperature regulating switch in
the unit regulates the coolant temperature between a low of 68°C
(154°F) and a high of 85°C (185°F) by automatically cycling the
heater.
The Hydronic 10 can be operated from the vehicle cab by an
on/off switch, a pre-select timer or a combination of both.
A flame sensor, temperature regulating sensor and overheat
sensor are among the safety features which makes the Hydronic
10 a safe and dependable heating system.

Heater
The heater is incorporated into the engine’s cooling system for
engine preheating
Follow these guidelines and refer to the engine plumbing diagram shown below.
• Install hose fittings into the engine block for pick-up and
return lines.
• Use existing holes in the engine block (ie. remove
blanking plugs when possible).
• Use shut off valves to ensure the system can be isolated
from the engine when not in use. Alternatively “T” piece
connectors in existing coolant hoses can be used if no
blanking plugs are available
• Provide 20mm (3/4” ) hose barbs for hose connections.
• Use 20mm (3/4” ) hoses to ensure adequate coolant flow.
• Keep the pick up and return points as far apart as
possible to ensure good heat distribution.
• Take the coolant from a low point on the engine to reduce
aeration in the system.
• Ensure proper direction of coolant flow by taking coolant
from a high pressure point in the engine and returning it
to a low pressure point. (ie. pickup from back of block and
return to the suction side of the engine's water pump).
• Ensure adequate flow rate through the heater by
comparing the incoming and outgoing coolant
temperatures while the heater is running. If the rise in
temperature exceeds 10°C (18°F), coolant flow must be
increased by modifying the plumbing.
• Ensure the heater and water pump are installed as low as
possible to allow the purging of air.
• If a bunk heat exchanger is incorporated into the system,
proper plumbing layouts must be followed.
CCaauuttiioonn::
The coolant must contain a minimum of 10%
antifreeze at all times as a protection against
corrosion. Fresh water will corrode internal heater
parts.
