More Specifications
Ultra High Efficiency
94% Thermal Efficiency
Lower energy costs: Up to 94% of the gas consumed by the Mod Con boiler is converted into heat, compared to a mid efficiency system where up to 40% of the heat can be lost through the chimney
Turndown Ratio 10 to 1
With a modulating burner combustion system and two independent boilers working together as one unit, the Mod Con Double Stack boiler is able to operate at a true 10:1 turndown ratio, saving fuel and providing comfort levels efficiently and evenly
Venting
Equipped with concentric venting, the Mod Con Double Stack requires only one exhaust connection through the wall or roof for exhaust vent piping
Complete flexibility with the ability to vent up to 150 ft.
Lower exhaust temperatures due to high efficiencies allows for the use of PVC or other plastic venting materials, saving on installation cost and time
Indirect Water Heater Integration
With the addition of a storage tank the Mod Con Double Stack VWH boiler can be converted into a hot water heater to provide ample heating and hot water, saving you space and money.
Quality Design
The 316L stainless steel provides excellent heat transfer properties and increased corrosion resistance.
The Mod Con Double Stack VWH heat exchanger is made without the use of gaskets with superior welding technology. It is also ASME approved and is 150 PSI relief rated.
Top and bottom boilers equipped a state of the art LED control interface with a built in sequencer, saving on both time and money during installation
Cascading: Link and sequence up to four Mod Con Double Stack VWH boilers to function together as one
Mod Bus Capabilities: Eliminate expensive external sensors and I/O hardware, collect data, and control the appliance directly using one connection
