FAQs about Heaters

How does HVAC heating work?

  • HVAC systems are made of several parts including the thermostat, furnace, evaporator coil, condensing unit, vents and refrigerator lines. The furnace is the piece of equipment used for heating purposes. Furnaces can use solar energy, heat pumps, electric resistance and combustion as heat sources. The furnace heats air, then distributes the air through ductwork or piping.

How do I calculate heat load in an HVAC system?

  • It’s important to make sure your HVAC system is large enough for the intended application. There is a formula you can use to calculate heat load. Take the square footage of the space, then multiply by 25 to determine the base BTUs (e.g., 2,500 sq. ft. x 25 = 62,500 BTUs). Then, factor in 100 BTUs per person and 1,000 BTUs per window and door (e.g., 4 people x 400 BTUs = 1,600 BTUs; 10 windows x 1,000 BTUs = 10,000 BTUs). Add them all together for a total heat load calculation (e.g., 62,500 + 1,600 + 10,000 = 74,100 BTUs).

What is a heat strip HVAC?

  • Adding electric heat strips to your electric furnace help convert the furnace to a fully electric comfort system that is compatible with most air conditioning systems. Additionally, any air handler can be fitted with heat strips. Heat strips are meant to handle extra tasks to assist the heat pump with certain tasks like defrosting the unit.
