A Low Mass Boiler with a High Efficiency

Interior Mod Con Boiler



The Mod Con has up to a 98% thermal efficiency with up to a 5 to 1 turndown. Older gas furnaces may only be using as little as 60% of energy consumed. Heating is the largest energy expense in most homes accounting for 35-50% of annual energy bills in colder parts of the world.

With the Mod Con, up to 98% of the dollar spent on heating is properly used to heat the building. That is real savings! It’s high grade Inconel burner and 316L stainless steel modulating burner allows this unit to provide adequate heating while saving energy and money. The Mod Con is a dual flame sensing unit with reliable spark ignition. It has a heating capacity of up to 6,800,000 Btuh!

Becoming Green

Not only does the Mod Con save you money, it is also eco-friendly. The Mod Con 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.



A Better Experience with Every Installation

The Mod Con has the ability to vent up to 200 ft’, offering complete flexibility. The lower exhaust temperatures, due to high efficiencies, allows for the use of PVC or other plastic venting material, saving on cost and time! The Mod Con is easily servicable due to its direct access to components through an easy to remove front cover. Stainless steel construction results in light weight packaging, making it even easier to install.

The Mod Con has the ability to be integrated with an indirect water heater. This allows the user to control the water heating through the boiler system controls, giving domestic hot water priority.
