Sorry I'm Drawing a Blank @ Calculating the Cost of Propane consumption in our Home.... We have 2 / 465Litre Tanks.. The Gauges read 78% at the Start of the Winter Season.. 52 Days later Gauges read 55% or 23% Consumed.. I'm drawing a Blank to Convert the 23% into Litre's is all.. Cheers Thanks

Our Bryant gas furnace started sounding like it had a bit of a rattle on start up, not all the time though. Decided to have it checked out for the season. When I looked at furnace for source of rattle, the motor in this assembly appeared to be running fine, I could not see any fault codes. Furnace guy checked it out for us but we were not at the house at the time. I have never met this fellow before, told him if anything needed replacing to leave the old parts at the house. Anyhow, returned to the house and found what I see online is called the "combustion blower assembly" but his bill calls it the inducer motor. I assume same thing. Question is .. could this assembly/motor have been the cause of the occassional rattling sound at start up? If the inducer motor needed replacing would it not have thrown a fault code? The replacement motor is the same motor I initially looked at to see if it was making the rattle sound, it wasn't and it seemed to be spinning fine? I haven't been at the house long enough to know if the rattle sound has been taking care of. For $450 I hope it is. But ... there is a part of me that wonders if these assemblies are an easy way for furnace guys to make a little extra money?? Also, I did read somewhere that the assembly should be replaced with exact replacement but ... furnace is 17 years old?? and I don't remember where I read that?? Is there any truth to this? thanks for your time
