I need help with estimating Gas Loads. I currently have three residential buildings that I heat with Oil, and I am looking to convert to gas. I need to estimate the BTUs required for each unit.
Unit # 1 is a 4000 sq mother daughter which has HWBB Heat, 2 stoves one dryer and 1 Heatmaker attached to the furnace
Unit # 2 is a 2000 Sq 2 family with HWBB heat, 2 stoves and 1 dryer and an elect HWH
Unit # 3 contains 3 one bedroom apartments w/ HWBB heat and a heatmaker on the furnace. There are a total of three stoves.
Is 1/4 PSIG ok for what I am doing?
Can someone give me a formula that I can use to estimate the load properly? Thanks
