A: Oh yes it is!
The KN boiler condenses with the best of the condensing boilers. It is fully condensing, fully modulating, and produces efficiencies up to 98% JUST like it’s competitors.
EX: With more durability
To the right is a standard condensing design known in the industry. It fires upward and condenses downward. The re-evaporation alone attacks the longevity of the boiler.
Q: “It’s not a true condensing boiler”Q: “It’s not a true condensing boiler”
How does Hydrotherm do it?
•Down-fired, balanced flow
- This controls the O2 level adding to the durability of the boiler design.
- Wipes condensate away instead of re-evaporating it.
- Pushes condensate to the base while the gasses pass through a careful pin design on the fireside of each section.
- Water blows off pins
- Condensate leaves boiler instead of sitting on the sections!
Q: “It’s not a true condensing boiler”Q: “It’s not a true condensing boiler”
-Spring-mounted ceramic burner
-On-burner pilot
-Lights at low gas pressures (can fire to rate at 2” wc)
-Condenses away from controls & burner unlike many of today’s condensing boilers.
-Balanced temperature rise with counterflow operation offers optimum efficiency and accurate modulation and turn down.

A: Oh no it won’t! In fact, not only will it not shock, it will last
considerably longer than typical steel or copper condensing boilers.
Durable TRUE cast iron design is 5 times the wall thickness of copper and 3 to 4 times the heating capacity of copper.
Pressure? ASME tested to 100 psi
Flow requirements… The best!
Ex. KN10 FLOW2.4 ft @ 100 GPM (Cv=100)Enough to allow for good modulationMost won’t need primary secondary pumping!
Q: “If the boiler is cast iron it will shock”Q: “If the boiler is cast iron it will shock”
Don’t be shocked!Don’t be shocked!Really the KN can’t shock because where
everyone else stopped with the fireside design, KN engineered the waterside pathways as well!
•Balanced, orificed flow
-.70” & 1” orifices
-< 5° between sections
-< 2° between flue outlets
•Maximum efficiency under all operating conditions
•Only 14 gallon water capacity so little opportunity for stand by losses.
•21 year thermal shock guarantee
Quick ‘Shocking’ Review on Quick ‘Shocking’ Review on Counter FlowCounter Flow• Pin design ‘in’ the section, much
like the exterior fireside ‘pin’ arrangement.
• Internally acts like a natural pump
• Balanced, orificed flow
• Only 14 gallon water capacity
• Low pressure drop - Cv=100
• No return water temperature limit. (Please make it liquid!)

A: Give us a break! Not a very professional play on words at all….
The KN boiler is a Mestek venture. Mestek is a 500 million dollar corporation owning and operating near 40 HVAC related companies. Mestek PURCHASED Hydrotherm and Hydropulse. After years of trying to fix the Hydropulse design, they stopped the production of this violent combustion process.
EX: Not a Hydropulse Boiler.
Mestek began as the HB Smith Company who has been manufacturing quality cast iron boilers since the late 1800’s. Smith is the cooperative in the KN venture.
Q: Q: “Call customer X…he doesn’t like the Hydro……”“Call customer X…he doesn’t like the Hydro……”
The production of HydroPULSE The production of HydroPULSE boilers halted late in 2006. Mestek boilers halted late in 2006. Mestek invested millions of dollars invested millions of dollars supporting this line of boilers while supporting this line of boilers while carefully developing the KN with Ken carefully developing the KN with Ken Coehn (Designer of the Aerco KC Coehn (Designer of the Aerco KC model boiler).model boiler).
Still they support the PULSE and Still they support the PULSE and continue to honor every warranty continue to honor every warranty claim as the stand up 500 million claim as the stand up 500 million dollar corporation they are!dollar corporation they are!
A: History of the KN design:
• Mestek employed a brilliant boiler designer in Ken Coehn.
• Ken Coehn developed the Aerco KC boiler but claims his lifetime goal was to develop a true condensing cast iron sectional boiler.
• The KN passes all the intense testing and development and Mestek determines the boiler should bare the Hydrotherm logo (Instead of the Smith Name).
• The boiler fires 2000 mbh in near silence, modulates effectively, and shares the same performance curves of it’s competitors without the use of external heat exchangers (such as Camus) which truly are simple stack economizers on a copper boiler.
