Screening estimate only. These tools use only the values you enter and simple planning math. A professional Manual J load calculation is authoritative for equipment sizing, room loads, and final purchase decisions.
Real heating cost varies with climate, defrost cycles, thermostat settings, backup heat, duct losses, and part-load behavior. HSPF2 is treated here as BTU output per watt-hour for the user-entered season assumptions.
