Roberts Mechanical Equipment is excited to present a whole new level of quality for high efficiency condensing boilers!  Mestek (Owner of RBI, Smith, Hydrotherm, and many other HVAC related companies) has completed a long and careful process by which they have 5 years of R&D and field application testing with a new high efficiency condensing boiler. 

What makes this boiler different from the others is that this boiler is a true CAST IRON boiler.  Would you expect any less from a company anchored by one of the world's oldest and most respected cast iron boilers (Smith aka HB Smith)? Most condensing boilers suffer a deficiency in life expectancy based on materials such as thin steel or copper. Condensation is highly acidic and can do a great deal of damage quickly to such materials.  Limited life spans are inherent to condensing boilers, but now Mestek has found a way to give your customers the efficiency available in this era with the durability of the old 'workhorse' cast iron boiler of years past!

The boiler is completely packaged and assembled incorporating a TRUE FLOW matching air ratio gas valve modulating system (Linkage-less) which will give you a 4:1 (Some models 5:1) standard turndown in key sizes such as 600MBH, 1000MBH, and 2000MBH inputs. 

"This boiler is one of the most impressive boilers I've seen come out in the last 15 years! " said Grant Roberts President of RME.  " In a time when we are seeing manufacturers find anyway they can to hold heat in the exchanger of the boiler to maximize the efficiency, we have never seen a boiler like this in cast iron.  The passages are large, the material is cast, and the controls are non proprietary.  It runs whisper quiet and actually has a smaller footprint than many of the new designs I've seen out there." continued Roberts. 

Other condensing designs use a coiled small passage water tube exchanger, or secondary exchangers with internal pumping to achieve higher efficiency.  Some are of the smaller firetube design with very small bends which may not be accessible for cleaning.

The KN Series boiler was engineered and developed by Ken Coehn a pioneer in the boiler industry. The boiler only requires that the return water is liquid and does not have a minimum return temperature requirement.  In fact, they are so confident in the design, they have a 21 year warranty against thermal shock. The cooler the return water the higher the efficiency rating.

Roberts said in closing; "While new manufacturers pop up each year, it's refreshing to see a dominating manufacturer keeping up and spending valued time and resources to develop new technology.  Best of all, unlike the unknown companies breaking into the market place from Canada and other areas, Mestek (Westfield, MA) has the financial backbone (250 Million Dollar Corporation) to make this another dominant product in the market place (Much like RBI's new Futera III, and Smith's new 28HE cast iron boiler).  You can only accomplish this with impeccable support, continued R & D, and the willingness to make every situation right without concern for cost based on limited resources!  You aren't going to find this with the 'copy cat companies' coming out today.  There's no way they have the resources to fund such support."
