Thermo Dynamics Boilers S 100 High Altitude Hydronic Oil Fired Water Boiler with AFG Burner, 84.2% AFUE, 140000 BTU/hr
  • Allows the installer to size the boiler more closely to the home heating needs for greater efficiency, the lowest firing rate, 0.85 - 87,000 BTU/hr, is necessary for many well insulated homes where the heat loss is minimal
  • 1" thick pyrolite ceramic fiber combustion chamber, fast warm-up - glows to incandescence in 11 - 17 sec, large diameter allows brushing flue passages without punching through chamber
  • S-series operates at 140 psi pump pressure for better fuel atomization, thereby having the ability to tolerate fuel oil with heavy ends
  • S-series is standard with a state-of-the-art, solid state ignition system, making it more tolerant to low VAC age or VAC age fluctuations
  • Integrated ignition
  • Electronic delay with solenoid valve clean-cut fuel pump
  • S-series has exceptional water content, the first size has 16 gal of water, high water volume and placement of the coil in the hottest part of the boiler allows for maximum coil performance
  • The unique tube design of the S-series boiler heat exchanger slows the flue gases, allowing for more effective heat transfer without the need for extreme baffling often seen in other vertical tube boilers
  • Each boiler is constructed and hydrostatically tested in accordance with ASME boiler code, the capacity and efficiency are rated in accordance with the standards of the institute of boiler and radiator manufacturers (IBR)
  • Built-in air scoop purges air from the system providing a quiet, trouble free hot water heating system without the use of external devices
  • Extended flange coil is away from the boiler for easy accessibility, use of ribbed neck carriage bolts eliminates the problems encountered when a weld stud is broken during servicing, large coil plate allows for a greater gasket sealing area
  • Extended weld fittings of SA106-schedule 80 seamless pipe extend beyond the jacket and allow the service technician or homeowner to see small leaks that, if undetected, could later damage the boiler shell and void the warranty
  • Easy cleaning and maintenance accessibility to combustion areas and the open tubes make it easy for the service technician to thoroughly clean the boiler
  • Flush jacket, altitude, temperature and pressure gauge, ASME relief valve, thankless heater - 3 gpm, factory assembled, wired and packaged, 3450 RPM high-speed flame retention oil burner, interrupted primary ignition, hydronic triple aquastat relay, 007 circulator pump, brass boiler drain valve

Thermo Dynamics Boilers HT-90/110 Steel 3-Pass Oil Fired Water Boiler, 84.2 - 85.1% AFUE, 126 - 154 MBH Input, 109 - 132 MBH Heating
  • A wet-base design, a horizontal tube and a 3-pass heat exchanger make this one of the most efficient boiler designs available
  • A 5 gpm tankless coil with a 30 gal boiler water content assures abundant hot water
  • Forced draft burner eliminates chimney draft problems
  • Multiple firing rates on the same unit
  • 1-piece boiler construction ensures years of trouble-free service and there are no push nipples or "O" rings to leak
  • Heat exchanger easily accessible for cleaning
  • The 85% AFUE rating is among the highest department of energy (DOE) ratings
  • Due to the horizontal tube and wet-base, the HT is remarkably quiet, the unit-flow path of combustion gases allows for smoother, quieter combustion than firebox, wet-leg designed boilers
  • Each boiler is constructed and hydrostatically tested in accordance with ASME boiler code, the capacity and efficiency are rated in accordance with the standards of the institute of boiler and radiator manufacturers (IBR)
  • Limited lifetime warranty
  • Built-in air scoop purges air from the system providing a quiet, trouble free hot water heating system without the use of external devices
  • Extended flange coil is away from the boiler for easy accessibility, use of ribbed neck carriage bolts eliminates the problems encountered when a weld stud is broken during service, the large coil plate allows for a greater gasket sealing area
  • Weld fittings extend beyond the jacket and allow the service technician or homeowner to see small leaks that, if undetected, could later damage the boiler shell and potentially void the warranty
  • Easy cleaning and maintenance accessibility to combustion areas and the open tubes make it easy for the service technician to thoroughly clean the boiler
  • No tight, pin-type passage ways with hidden nooks and crannies, making a thorough cleaning possible
  • A well-maintained boiler continues to perform at higher efficiency and is less likely to develop service problems
  • Factory mounted/wired burner and controls
  • Fully insulated heat exchanger with powder-coated cabinet
  • Equipped with triple aquastat, circulator and temperature/altitude gauge
  • (2) 1-1/2" return
