Hydrotherm’s NEW KN Series Condensing Boilers When They Make CENTS! Beware Of’s Disadvantages Advantages Why Hydrotherm is the Condensing Boiler of Choice! Hydrotherm’s NEW KN Series

180F 98% 60F 83% When They Make “Cents” $18,000.00 - $ 25,000.00 BUDGET 2000 MBH BOILER: COPPER FIN 85% - $14,000.00 CAST IRON FD - $ 9,500.00 STEEL FD - $14,500.00 COPPER FIN 82% - $ 9,000.00 ATMOSPHERIC - $ 7,500.00 CONDENSING BOILERS: $18,000.00 - $ 25,000.00 RETURN TEMP 60F 180F EFFICIENCY 98% 83% DON’T FORGET HIGH EFFICIENCY MAY MEAN: SPECIAL VENT MATERIAL CONDENSATION HANDLING CONTROL CONSIDERATIONS ADDITIONAL RADIATION INCREASED MAINTENANCE TECHNICALLY DEMANDING SERVICE PROPRIETARY COMPONENTS SPECIAL PUMPING OR PRIMARY/SECONDARY PIPING ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) When They Make “Cents” Low Temperature Application 180F – 200F Cannot Afford the Average Condensing Boiler. Savings = Efficiency – First Cost! Carefully Consider All the Additional Installation Cost!

Condensing “Beware Of’s” KNOW THE SYSTEM TEMPERATURE LIMITATIONS CONDITION OF THE SYSTEM AND WATER (SMALL PASSAGES) CONVERTING VENT? LINING CHIMNEY? SIDE WALL PLUME AND BRICK DAMAGE? MULTIPLE BOILERS DON’T ALWAYS NEED HIGH TURNDOWNS. WILL BACK LOADING MAKE SENSE? DON’T LOOK AT LITERATURE FOR OUTPUT – CHECK CHART ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) MASONRY CHIMNEYS CANNOT HANDLE CONDENSATION AL29 ABOUT $90 PER FOOT WATCH HORIZONTAL EQUIV. MULTIPLE BOILERS AND HOW THEY ARE BREECHED. CAN BE VERY NOISY.. WHERE IS MECH ROOM LOCATED VARIES BY MANUFACTURER WATCH YOUR SPECS AND EQUALS! THROUGH A BRICK WALL IS RISKY BUSINESS! ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) NEGATIVE CONDITIONS CAUSE RANDOM HARD TO DETECT LOCKOUTS. DIRECT CONNECT – BE SURE TO SPEC FACTORY FREEZE PROTECTION. SIDEWALL – BE SURE TO USE SAME SIDEWALL AS VENT. INLET AIR PIPE CAN CONDENSE AND DRIP IF NOT INSULATED OR DOUBLE WALL DON’T COMBINE AIR INLETS ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) LOOK FOR PD AND GPM REQUIREMENTS. LOW FLOW MEANS HIGH DELTA T. WATCH RISE AT HIGHER TEMPERATURES. PRIMARY SECONDARY MAY BE NEEDED. ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) Condensing “Beware Of’s” GAS REQUIREMENTS CAN BE AS HIGH AS 8” WC. TOUGH IN MANY AREAS OF CLEVELAND AND AKRON. USE SPECIAL CARE WHEN USING MULTIPLE BOILERS. ABILITY TO FIRE ALL BOILERS AT VARIOUS CAPABLE FIRING RATES MEANS ‘CAREFUL’ SIZING OF MAIN GAS BRANCH AND GAS DROPS TO BOILER. ( NOT ALL CONDENSING BOILER REQUIRE ALL OF THESE CONSIDERATIONS ) Venting Temperature Rise Gas Pressures Combustion Air Requirement Existing Conditions Be sure to watch your EQUALS! Use disclaimers in Spec!
