    • Guide to Boiler Heating System Components: Part I
    • There are many different components to each boiler heating system.PexSupply.com can work with you to make sure you have all of the parts,installation equipment, and planning pieces needed for your next DIY project.Boiler Heating System Components:1 - Boiler 11 - Zone Valve Controller2 - Indirect Water Heater 12 - Circulator Flanges3 - Boiler Header 13 - Zone Valve4 - Low Water Cut-Off 14 - Ball Valve5 - Switching Relay 15 - Boiler Drain6 - Thermostat 16 - Temperature Gauge7 - Circulator 17 - Fill Valve8 - Tempering Valve 18 - Backflow Preventer9 - Expansion Tank 19 - Boiler Reset Control10 - Air Eliminator 20 - Check Valve
    • Heating System Diagram
    • 1 – Boiler The first piece of the boiler based heating system is of course the boiler. Boilers are used to heat water or make steam. They are either powered by electricity, natural gas, or oil, which require different piping systems for each type. Shop Now: • Tax Rebate Boilers • High Efficiency Boilers • Weil McLain BoilersLearn More About Boilers
    • 2 – Indirect Water Heater After water is heated in the boiler, it is passed through a heat exchanger located in the storage tank of the indirect water heater. This allows the boiler or furnace to turn on and off less frequently, which helps save energy and money. However, separate water heater is not needed if you already have one. Not all applications need Shop Now: the use of water heaters either. • Weil Mclain Indirect Water Heaters • Smart Indirect Water Heaters • Bradford White Indirect Water HeatersLearn More About Indirect Water Heaters
    • 3 – Boiler Header Boiler headers are also known as boiler manifolds, which function as a hub for heating systems. Boiler headers come in variety of sizes with different number of outlets.Learn More About Boiler Headers
    • 4 – Low Water Cutoff A low water cutoff detects when water levels in hot water and steam boilers reach a level lower than the minimum required for safe operation. It then turns off the boiler and prevents possible boiler failure or fire/explosion. Low water cutoffs are one of the most important parts of a safe hydronic heating systems.

    • 5 – Switching Relay Switching relays are used to control temperatures of water in a heating system. They are used to connect thermostats to circulator pumps so that the circulator pump goes on when the thermostat calls for heat.

    • 6 – Thermostats Thermostats are used to control the temperature of specific rooms of your house. This allows you to adjust temperatures of each room to fit your comfort. Thermostats come with different functionalities such as programmability, application type, stages, user interface, voltage and changeover type. Shop Now: • Honeywell Thermostats • White Rodgers Thermostats • Tekmar Thermostats • Robertshaw ThermostatsLearn More About Thermostats
    • 7 – Circulator Circulators, also known as pumps, help move water through a heating system at the needed rate. When choosing a circulator it is important to know the application, GPM, head range, material, voltage and horsepower needed. Shop Now: • Taco Pumps • Grundfos Pumps • Bell & Gossett Pumps • Wilo Pumps • Armstrong PumpsLearn More About Pumps or Circulator Pumps
    • 8 – Tempering Valve Tempering valves mix hot and cold water to produce water at a desired temperature. They are used for variety of radiant heating and domestic water applications. In domestic water applications, they ensure steady temperature ranging from 85 F to 150 F and help prevent potential burns. Shop Now: • Watts Thermostatic Mixing Valves • Watts N170 Commercial Tempering Valve • Watts 70A Hot Water Extender Tempering ValvesLearn More About Tempering (Mixing) Valves
    • 9 – Expansion Tank Expansion tanks help keep a constant pressure in potable water and closed heating systems by providing extra space for excess water to enter. Expansion tanks can help prevent pipes from being damaged from increased pressure. Shop Now: • Expansion Tanks for Heating Systems • Potable Expansion Tanks • Well Expansion TanksLearn More About Expansion Tanks
    • 10 – Air Eliminator Air eliminators help remove excess air from hydronic heating systems which will help prevent pipes and other components from damage caused by trapped air. Air can also prevent proper heat distribution. Air is created as pressure or temperature changes.
