Mod/Con Boiler Technology

 

Badger Boiler IBC 150 2013

Perfection
Modulating and condensing, gas-fired boilers (ModCons), meet our professional goals for nearly every hydronic heating system, new or retrofit: safety, reliability and efficiency. If we add to these; integration, we can talk about investing in ultra-high combustion AND system efficiency.

 

Let’s start with a gas-fired appliance at say, 98% thermal efficiency and use this superior heat source to supply water for bathing, heat for floors, walls, ceilings, sidewalks, driveways, pools, even forced air unit heaters. Mod/cons are also a perfect match for CAST IRON RADIATORS typically over-sized and thus able to satisfy space heating at very low operating temperatures for much of the heating season. System efficiency comes from engineering distribution and control systems that optimize a particular boiler’s capabilities.

 

Some otherwise knowledgeable contractors may try to convince you that high efficiency or (condensing) boilers are "too expensive", "unreliable" or that condensing boilers require "too much service". This was true of some units and particular installations of the past, but is no longer the case.

 

In the United Kingdom it is now mandatory to install condensing boilers in new construction and retrofits. Today most domestic boiler manufacturers offer condensing boilers (9 manufacturers offer 95 AFUE boilers!) most of which utilize European design and/or manufactured components. Many thousands of condensing boilers are operating in the US. In fact we recently serviced one of the first condensing boilers still working since 1990!

 

Mod/Con boilers stand alone in the level of sophistication they bring to any heating system. Early condensing boilers like the ones sold and serviced in the 80's and 90's would condense (that is, reduce the stack temperature from say 550 degrees Fahrenheit to 100°F) only when installed properly in an appropriate heating system.

 

Today a microprocessor is used to regulate the burner and produce the lowest water temperature necessary to replace the heat lost by your in your home. This low water temperature keeps the boilers condensing (and running) as much as possible. Operating like cruise control on your car, the boiler senses the outside air temperature and ramps the boiler operating temperature up and down with the weather. This is called OUTDOOR RESET and the combination of outdoor reset, condensate energy recovery and burner modulation has made the Mod/Con boiler the unmatched energy saver for space and hot water heating. Today there is a Mod/Con that will work with any hydronic system and is guaranteed to improve performance, comfort and efficiency.

 

P.S.

Most Mod/Cons can be set on the floor, hung on a wall, use plastic pipe for intake air and exhaust and are nearly silent while operating!
