Munchkin Boilers
 The
Munchkin Boiler is one of the most compact
and efficient residential boiler available on the market today.
Each Munchkin Boiler will modulate its firing rate to match
the energy needs of the living space. This feature provides
additional savings versus traditional single firing heaters.
With stainless steel construction, you can be assured that you
are buying the highest quality appliance. Proven European technology,
manufactured in the United States. A quiet operational appliance
is just another benefit that comes with the Munchkin boiler.
How It Operates
When the room thermostat calls
for heat, the Munchkin boiler control board will start the pump
and start to monitor the return water temperature of the system
before the heater will begin to heat the water. Once the controller
has sensed a drop in the return water temperature below the
temperature set point minus the differential set point, the
Munchkin boiler will start to heat the water. This eliminates
the boiler starting every time the thermostat calls for heat.
This feature keeps the system from short cycling.
Once the system has sensed
the temperature difference, the Munchkin boiler will activate
the blower motor for 5 seconds to prepurge the system before
starting the Munchkin boiler. The Munchkin boiler controller
will now start to modulate the premix burner based on analyzing
the return water temperature, supply water temperature, and
the set point temperature. By compiling this information, the
controller utilizes an algorithm to fully adjust the firing
rate while maintaining the desired output temperature. The pre-mix
burner fans have a low-voltage direct current drive motor with
a pulse relay counting. This system allows precise control over
the fan speed and combustion air volumes. Coupled with the Dungs
gas valve and the Venturi system set to provide a one-to-one
ratio of precisely measured volumes of fuel to air, accurate
and instant burner output is achieved. This keeps the Munchkin
boiler running at the highest efficiency. When the thermostat
is satisfied, the Munchkin boiler will then go through a 4 second
post-purge cycle before shutting off. Every Munchkin boiler
is equipped with an indicator light which will pulse constantly
in normal operation. When a problem occurs, the indicator light
will blink slowly to indicate the heater fault.
