Boiler and Water Heater FAQ’s
Boilers are appliances that heat water or make steam to use for Hydronic, Industrial, or Process heating applications. Water Heaters heat water for domestic use. This includes laundry, showering, cooking, consumption, cleaning, etc.
A Commercial Boiler is a piece of equipment that uses electricity or fossil fuels (Natural Gas, Diesel, Propane, Fuel Oil, etc.) to heat water.
Boiler temperatures vary. Reading and understanding the manufacturer’s operations manual is a good start. Another solution would be to consult with an Engineer or Facilities Manager to know the proper application to determine the needed temperature for the boiler.
A Condensing Water Heater is an appliance that runs on natural gas or propane that achieves maximum efficiency by keeping the return or inlet water to the appliance at less than 130F.
An expansion tank is generally installed to help the system manage thermal expansion. As the water heats up, the pressure in the system will increase. Increased pressure can result in early failure or leaking of the hot water piping or equipment.
