Clearing the Air about the
Hydrotherm KN Boiler
We are proud to represent one of the most durable,
efficient and innovative boiler designs in this industry.
The design is so unique, our competitors are
misrepresenting it for one or both reasons:
They don’t understand it
or
They can’t compete with it
Either way we would like to answer the tough questions brought to our
attention by local competitors.

Hydrotherm’s KN Boiler
Copyright Mestek, Inc. 2004
Q: “It’s not a true condensing boiler”
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”
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 reevaporating 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!
More on the Downfired Specific Design:
-
-
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.
Q: “If the boiler is cast iron it will shock”
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 FLOW
2.4 ft @ 100 GPM (Cv=100)
Enough to allow for good modulation
Most won’t need primary secondary
pumping!
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

Counter 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!)
Speaking of the:
CAST IRON SECTION
•
American made in the Boyertown
Foundry (HB Smith)
•
1/4” wall thickness for
unmatched durability.
•
Deep-pin design is specifically
engineered for proper fireside
gas flow.
•
Fully machined fit with no push
nipples.
•
Independent studies show the
cast iron can hold up to 60 plus
years of condensing.
Q: “Call customer X…he doesn’t like the Hydro……”
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.
The production of HydroPULSE
boilers halted late in 2006. Mestek
invested millions of dollars
supporting this line of boilers while
carefully developing the KN with Ken
Coehn (Designer of the Aerco KC
model boiler).
Still they support the PULSE and
continue to honor every warranty
claim as the stand up 500 million
dollar corporation they are!
Q: “So and so doesn’t like the Hydro……”
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.
Could of easily been named
with the Smith logo!
Q: The boiler doesn’t meet commercial codes..
A: Huh?????? Meets all of the following

CSA

What our competitors won’t tell you…
• Boiler is nearly silent all the way up
to 2000 mbh
• Accepts 4-20ma signals and gives
you TT enable and disable points.
• Available with HeatNet control
•
•
system which is Bacnet compatible
and independently does outdoor
reset and modulation on multiple
boilers.
Fires TO RATE with incoming gas
pressures as low as 2” w.c. (still
fires at 1.5” w.c.)
Power consumption under 2 amps
in low fire.
Over the counter parts!
• Text display
• Nearly completely non proprietary
•
•
• Oh, don’t forget the KN can
take ANY return temperature!
•
•
•
(standard ‘over the counter’
controls and trim).
Heavy duty commercial/industrial
RM7800 series flame safeguard
with screen on every boiler.
Standard Honeywell UV scanner
(C7027A) so you have no
rectification rods to adjust or
replace.
Primary/Secondary pumping most
likely not needed!
Easy to service and adjust all
components (not cased up).
Low profile for easy service and
fits through a standard door.
They won’t tell you this:
• Air cooled UV flame
detection
• Control condensation
protected by small air
pump
• 14,000 volt interrupted
ignition
• 8000 btuh pilot
They sure won’t show you this:

Quality?
• All stainless steel jackets.
• Heavy duty base designed
for rigging with forks.
• Super heavy duty burner and
head assembly.
• Direct connect combustion
air and smaller venting sizes.
• All external controls and
adjustments
• Oh, don’t forget the KN can take ANY return
temperature as long as it’s liquid!
Did they tell you the KN can’t foul as it
automatically adjust combustion for varying
combustion air rates.
