There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers. Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers). (more…)
Heat Trace Tape Control for HVAC Piping - HVAC Piping systems, especially in the Northern regions, need a way to freeze protect piping the runs outdoor which is a necessity in many different HVAC application. To protect HVAC piping from freezing heat trace tape is wound around the pipe and controlled by an outdoor thermostat or temperature control that energizes the heat trace tape and keeps the pipe from freezing.

Air Handling Unit Components 2: Heat - There are many different types and arrangements of heating systems for air handling units and these types of heating systems and arrangements of heating systems vary from commercial to residential. Some air handling units do not have any heat source inside them at all but have remote heat for zoning. The air handling unit provides the airflow and the remote heaters provide heat for zoning.
Sometimes the air handling unit is a VAV air handling unit and other times it is just to provide air for a duct heater whether the duct heater is gas-fired or electric. For air handling units which some have heating systems inside the five main ways of providing heat for air handling units are:
