www.triangletube.com Prepared for: Customer Name: Day Phone: Street: Evening Phone: Street: Cell Phone: City, State, Zip: email: Heat lost in Flue gas = 5% Heat gained by condensing = 10% Triangle Tube Boiler Fuel Cost Savings Worksheet Heat extracted without condensing = 85 % Total Efficiency = 95% Triangle Tube’s boilers gain efficiency over older boilers by: Modulating = running longer at lower temperatures Condensing = gaining heat from flue gas vapors Outdoor air = Old boilers send indoor air through the boiler and up the chimney, wasting heat and creating drafts. Triangle Tube boilers use outside air for combustion, eliminating this waste. Outdoor Reset = Adjusts the temperature of the system based on the outside temperature. As the outdoor temperature increases, the boiler system temperature decreases, improving efficiency. The Prestige Condensing Boiler by Triangle Tube. Maximum Efficiency. Maximum Reliability. Maximize the Return on your investment ! Upgrade your domestic water heater to a SMART Tank. Use your new high efficiency boiler to heat your hot water too. SMART tank benefits: The Prestige boiler leads the industry with a unique “fire tube” heat exchanger. The benefits include: • Self cleaning design minimizes maintenance. • Tank-in-Tank design provides more hot water from a smaller tank. • Foam insulation and no flue minimizes heat loss. • LIFETIME Guarantee ! • Self-cleaning stainless steel design minimizes maintenance. • Advanced control optimizes fuel efficiency. • Tuned intake for Quiet operation. • 95% AFUE efficiency for low fuel costs. Now is the time to upgrade to Prestige. Take advantage of the $1500 Stimulus incentive. Make the SMART choice. It is the last hot water heater you will ever pay for.
www.triangletube.com Boiler Efficiency Evaluation Information from Existing (Old) Boiler Rating Plate Boiler Output: BTU/Hour Boiler Input: BTU/Hour Existing Boiler Efficiency Calculation Actual efficiency for older, Non-Modulating Boilers is approximately 5% less than the rated Output / Input Ratio. This reduction is due to standby losses, chimney drafting losses, standing pilot losses, use of indoor combustion air, lack of outdoor reset, and other factors. Triangle Tube boilers virtually eliminate all of these losses. Approx. efficiency of the existing boiler = EFFOld= ([Boiler Output/Boiler Input]-0.05) X 100 Example: Boiler Plate Data: Input = 130,000 BTU/Hr, Output = 105,000 BTU/Hr. EFFOld = ([ 105,000 / 130,000 ] – 0.05) X 100 = 76 % Your calculation: EFFOld = ([ / ] – 0.05) X 100 = % Boiler Efficiency Ratio Boiler Eff. Ratio = EFFOld / EFFNew Triangle Tube EFFNew = 95% Example: Boiler Eff. Ratio = 76% / 95% = 80% / 95% = % Boiler Eff. Ratio = Total Fuel Cost Savings X = Annual fuel cost with old boiler. Boiler Eff. Ratio (from above) Annual fuel cost with Triangle Tube boiler. Cost Savings * = Annual fuel cost with Triangle Tube boiler. Annual fuel savings with Triangle Tube boiler. Annual fuel cost with old boiler. * To achieve the highest efficiency, outdoor reset must be used. * The numbers shown here are a basic comparison based on history. Actual fuel costs will vary depending on actual fuel prices, weather, degree days, thermostat settings, and overall weatherproofing of the building. Mkt – Fuel Savings NG – 2010-09
