Description for Lochinvar WHN-110-HA

Note: This is a High Altitude Model Boiler for 3,000-12,000 ft.

The KNIGHT® Wall Mount, engineered with Lochinvar's exclusive SMART SYSTEM control and an array of other innovative features is far ahead of any heating boiler in its class. It promises and delivers ultimate ease of installation and maintenance. With up to 99% thermal efficiency, low-NOx emissions and a fully modulating burner, it is the best "green choice" for today's environmentally focused market.

Features

  • Advanced Negative Regulation Technology:
    KNIGHT safely and reliably operates with supply gas pressure as low as 4 inches water column. Negative Regulation (Neg/Reg) technology automatically adjusts fan speed to ensure the correct volume and mix of fuel and air throughout the firing range.
  • Fire Tube Design:
    This fully welded ASME Certified stainless steel heat exchanger uses oval shaped tubes to pass heat from the products of combustion into the water stored in the vessel. To facilitate heat transfer the tubes are manufactured with dimples to slow the flue products and extract available latent energy. With a fire tube design the flue products are inside tapered passage ways and the water passed through a vessel. Since the flue products pass through tubes and the water is circulated through a larger diameter vessel a fire tube design allows for minimal head pressure loss through the boiler which allows the boiler to be installed easily into various hydronic applications.
  • Water-Backed Combustion Chamber:
    An outstanding feature of the fire tube design is a water backed combustion chamber. By having the combustion chamber surrounded by water the Knight Wall Mount has more heating surface area. This larger heating surface area allows for efficiencies up to 99%.
  • Fully Modulating Burner:
    The SMART SYSTEM allows fully modulating combustion with 5:1 turndown. The burner can fire as low as 20% of maximum input and modulates the firing rate up to 100% as demand increases. The burner is a single stainless steel assembly covered with woven steel mesh and fires in a 360° pattern along the entire length of the burner. This allows the compact KNIGHT to exceed the modulation capacities of units with larger multiple burners.
  • Direct Venting up to 100 ft:
    KNIGHT offers 5 venting options and tremendous flexibility for placement of units within the building, because it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC or AL29-4C stainless steel vent pipe. A sidewall vent termination kit is standard equipment with every KNIGHT boiler.

PLEASE NOTE: The product weighs 159 lbs. and may require the use of a
lift gate.
If you do require a lift gate at your delivery, you'll have the option to add this FREE of charge when you checkout.

Incredibly intelligent boiler

By Rattler

from Denver, CO

Comments about 89,000 BTU Output Knight High Efficiency Boiler (Wall Mount) High Altitude Model:

Incredibly intelligent boiler that is also energy efficient. Nice control options. Comes with a grundfus 3 speed boiler circulator pump. I coupled this with a squire indirect tank for the seamless integration of the smart control. Very happy with my purchase and look forward to many, many years of faithful service.
One thing that hung me up and I needed to call Lochinvar tech support was that it still requires an external transformer to power the thermostats and the end switches of the zone valves simply hook up to the low voltage board to signal the circulators and firing of the boiler.

Be sure to do a heat loss on your house. I replaced a 155,000 BTU cast iron with this 110K unit and it may still be too big. I have the ramp delay set at 20% firing rate.

Very nice unit and it's made IN THE USA!
