The HS2000E is supplied as standard with a solid state
electronic thermostat which automatically switches the unit on and off to
maintain the desired temperature. When the room temperature drops below
the selected level, the Heatsource will automatically ignite and run until
the cabin reaches the selected temperature. The thermostat is an easy to
fit surface mount design and integrates with the new electronics fitted to
the HS2000E heaters. Simple intuitive controls enable easy switching
between the gas and electric modes and a constant heater feedback loop
enable quick and easy system diagnose. Selectable electric hook up power
levels easily ensures you do not over load your available supply.
Gas Efficiency
With forced air combustion and the Propex two stage stainless steel
heat-exchanger, the HS2000E is a clean and highly efficient way to heat
your vehicle or boat. Air for combustion is taken from outside your
caravan or boat and passed into the combustion chamber having been mixed
with gas during three aeration stages, it is ignited automatically and
heats up the large surface area of the heat-exchanger. The Heatsource
units are totally room sealed and exhaust all products of combustion
externally through the neat 22mm i.d. stainless steels flue pipe. To add
to the efficiency, cabin air is normally re-circulated in preference to
using cold air from outside. The HS series heaters are also very efficient
on12 volt electrical current consumption drawing less than 1.7 amps on gas
operation or 2.2 amps during mains electric operation.
Mains Electric
For those using a mains hook up there is the option of using the
powerful electric element with efficient heat exchanger built in. Three
settings are available giving 500W, 1 KW or 2 KW of heat output and
drawing a maximum current of 9 Amps. The motor speed is altered to suit
each power level to ensure maximum efficiency or, when on low 500w setting
keeping motor and air noise to a minimum for night time running. The
heater is supplied with a mains cable and moulded 3 pin plug.
Quiet Operation
Propex heaters are designed to be quiet in operation without
compromising air throughput and heat output. There will always be some air
noise from a system that produces a healthy throughput of air, however, by
using high quality balanced fans and smooth enclosed motors with ball race
bearings, noise is kept to a minimum. Noise is also unaffected by high
voltage, a common occurrence with battery charges, solar panels etc
permanently wired. The micro-processor electronics regulates the motor
voltage so that the fan speed does not alter between 10 to 15 volts.
Safety
Heatsource blown air heaters conform to the latest European standards
for both the appliance and the electronics and during the rigorous testing
the focus is very much on safety. The heaters also have to comply with an
enhanced version of the Electro Mechanical Compatibility Directive to
ensure they do not interfere with other electronics and that they are
immune from interference by other electronics. The intelligent electronics
are continuously monitoring the operation of the heater to make sure
everything is operating correctly and safely. This includes monitoring of
the flame, case temperature, combustion airflow, gas solenoid valve and
voltage. Should any of these stray outside of the predetermined levels,
the heater will be switched off and the red light on the thermostat will
indicate a fault by flashing a certain number of times.
Installation
The HS2000E can be supplied with complete fitting kits to suit either
vehicle or marine applications. In vehicles and caravans the unit is
usually mounted in a bed-box or cupboard, flued downwards through the
floor and out to the side of the vehicle using flexible stainless ducting.
These ducts (22mm i.d. for the HS2000E) are supplied as standard in
lengths of 750mm for vehicles and 1 metre for boats. The ends are finished
with neat stainless steel end-caps which comply with EN624. The heat is
ducted to one or more outlets through tough highly flexible 60mm ducting.
In the case of multi-outlet installations, the first outlet is an open
outlet with directional control and the rest are closable and are used in
conjunction with the appropriate sized plastic Y-branches. Marine
applications feature an attractive polished stainless steel through hull
fitting which accepts the stainless steel pipes for the flue outlet and
the combustion air inlet. Extra ducting and stainless steel bulkhead
mounting brackets are also part of the marine fitting kits.
