Some things to know about Boilers:
Power Supply:
Standard Version:
Power Supply to Solenoid Valve on the Fuel Pump - 24v
Power Supply to the Fan Motor - 240v or 415v
12v Version:
Power Supply to Solenoid Valve on the Fuel Pump - 12v
Power Supply to the Fan Motor - 12v
(The 12v boiler is supplied with industry standard Electromechanical transformer,
which is physically big (and more expensive)). Also available with a Danfoss
Electronic 30ma Transformer.
Temperature Rating:
The pressure cleaning industry generally rates temperature of the hot water generated
at 90°. Due to a number of factors, including burner motor size, coil height and coil tube
thickness, and the general principles of thermal efficiency, most hot water machines do
not generate hot water to 90°
While the table on the facing page declares “true temperature”, our boilers are consistent in
performance to those generally available in the market.
Coil Wall Thickness:
The tube wall thickness of a burner coil is not in itself an accurate judge of the quality of a
coil. The wall thickness of a BAR coil is 2.5mm. A competitor coil, the Pt for example, has a
wall thickness of 3.6mm.
If the outside diameter of the tube is the same (for eg 3/8”), the extra wall thickness must
reduce the internal passage that water can flow through.
A thicker wall and reduced internal passage means less efficiency, as the water takes longer
to heat and there is more thermal (heat) loss from the extra steel.
In summary, a thicker walled coil will provide longer life and much reduced efficiency, while a
thinner wall will provide a shorter life and much increased efficiency.
