Munchkin

Munchkin boilers are one of the most compact and efficient heaters 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 USA.

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 Honeywell 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.

Prestige

Condensing Stainless Steel Sealed Combustion Wall Mounted Boiler

The Prestige can be direct vented up to 60 feet out a side wall with PVC or ABS pipe.

The Prestige requires minimal installation space, operates quietly and features an attractive jacket with a digital control panel. The boiler is equipped with a stainless steel premix burner and is available in natural gas or propane.

Stainless Steel Heat Exchanger

• Unique geometry: 3 consecutive baffles direct water flow through the exchanger and around the combustion chamber
• Highest water content in the industry
- Stable temperature control
- Less sensitive to water flow
• 439 Grade Stainless Steel. Unparalleled resistance to corrosion
• Less sensitive to sludge
• Self Cleaning: condensate washes combustion residue away when streaming down the tubes resulting in a constant efficiency and reduced maintenance.
• Low pressure drop

Crown

Gas-fired hot water boiler
Perfect for residential and light commercial applications with chimneys

Begun as Crown Industries in 1949, this family owned and operated business began distributing heating product accessories such as oil burners, operating controls and cast-iron radiation throughout the Northeastern United States.

During the 1970's, Crown began a period of rapid growth with the introduction of its residential cast iron boiler line. By the 1990's Crown Boiler Co. had grown to be a national company; supplying high quality yet competitively priced Hydronic boilers through a network of regional warehouses.

ARUBA 3 is CROWN's best selling gas-fired, hot water boiler. It comes in a wide range of sizes from 37,000 to 295,000 BTU/HR input.

Crafted with a rugged, cast iron heat exchanger and stainless steel burners that are both backed by a lifetime limited warranty, the ARUBA 3 offers proven-in-service reliability, simplicity of design and economy in its purchase price and consumption of fuel.

The ARUBA 3 is available with standing pilot or electronic ignition for greater energy efficiency. Honeywell controls provide reliability, ease and convenience.

Attractive and durable, the two-tone, powder-coated jacket resists scratching. Plus, it's insulated to retain heat. The ARUBA 3 meets all national standards, and the heat exchanger meets the specifications of the American Society of Mechanical Engineers.

ARUBA 3 is the latest in a series of designs that CROWN engineers have created for ease of use, constructed for long life and engineered to provide the most value for each energy dollar. That's CROWN's commitment to quality.
