    For over a century Peerless has dedicated itself to making efficient, durable boilers. The PureFire line is emblematic of these qualities. This is a direct vent, condensing boiler with DHW priority and an internal condensate system. A stainless steel burner and heat exchanger discourage corrosion and wear. The combination of first-rate components and advanced technology make the PF-110-N an excellent choice for heating your home. The PF-110-N is compact and requires zero clearance to combustibles, making installation flexible and easy. Front-mounted controls with clear error displays confer that same simplicity to maintenance. Between the efficiency-enhancing features and the quality construction, Peerless PureFire Hot Water Boilers are an attractive and reliable heating solution.
  • Modulating Burner
  • The PF-110-N uses a modulating burner to scale heating to your needs. This burner will vary its output based on your desired temperature, preventing the overuse of energy. Anti-cycling times set during installation prevent short-cycling.
  • LoNOx Operation
  • Not only is the PF-110-N environmentally friendly by virtue of its tremendous efficiency, but its LoNOx operation means significantly reduced emissions and a minimal environmental footprint.
  • Equipped for Outdoor Reset
  • PureFire hot water boilers include an outdoor temperature sensor and outdoor reset capability. With outdoor reset control to balance your heat production, the PF-110-N improves efficiency and comfort automatically.
  • Condensate System
  • All Peerless PureFire boilers have an internal condensate system. This system protects your heat exchanger from condensate backup with a float switch. It also neutralizes the acidity of any condensate produced.
  • Adaptable
  • The PF-110-N hot water boiler may be converted

General Information
Product Line
Medium Learn More
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Direct Vent
DHW Production Learn More
DHW Production
DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.
Modulating/Staging Learn More
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

AFUE Learn More
AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More

Maximum Input Capacity Learn More
Maximum Input Capacity
The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.
110000 BTU
Minimum Input Capacity
27500 BTU
DOE Heating Capacity Learn More
DOE Heating Capacity
Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.
102000 BTU
Net I=B=R Capacity Learn More
Net I=B=R Capacity
I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.
89000 BTU
Ultra Low NOx Emissions Learn More
Ultra Low NOx Emissions
NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
