A Low Mass VWH with a High Efficiency
The Mod Con Double Stack VWH is up to 98% thermal efficient with a 10 to 1 turndown. Up to 98% 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.
The modulating burner combustion system and two independent boilers work together as one unit and is able to operate at a true 10:1 turndown ration, saving fuel and providing comfort levels efficiently and evenly.
The Perfect Fit
The Mod Con Double Stack VWH comes in two model sizes: 1 million and 1.7 million BTU. It features a built-in cascading capability allowing up to four boilers to be linked together. Cascading provides increased turndown ratios, built in redundancy and a total heating capacity of up to 6.8 million BTU!

Becoming Green
Not only does the Mod Con DS save energy and money, it is also eco-friendly. The Mod Con DS Boiler has ultra-low NOx emissions providing additional environmental savings due to its combustion control system, which minimizes levels of nitrogen oxide. If NOx levels are not reduced, oxidants can build up in the atmosphere and have harmful effects on human health. The Mod Con is an eco-friendly choice, protecting the environment while saving your energy and money.
An Easy Installation
The Mod Con DS VWH is equipped with concentric venting and requires only one exhaust connection through the wall or roof for exhaust vent piping. It has complete flexibility with the ability to vent up to 150 ft.
The lower exhaust temperatures due to high efficiencies allows for the use of PVC or other plastic venting materials which saves on installation cost and time.
The Mod Con DS VWH has indirect water heater integration. With the addition of a storage tank, the VWH can be converted into a hot water heater to provide ample heating and hot water to save you space and money!
High Heating with High Quality
The Mod Con Double Stack VWH is manufactured with 316L stainless steel to provide excellent heat transfer properties and increased corrosion resistance. The heat exchanger is made without the use of gaskets with superior welding technology. It is also ASME approved and is 150 PSI relief rated.
