Re: At 7F outside heat pump maintained 73F indoors

said by pandora:

My estimate is 3,500 watts of electric resistive heat is about one U.S. BTU. 2 tons is about 7,000 watts of resistive electric.

I'm not sure what (watt? ) you're saying here.

1 Watt = 3.412 BTU/hr

1 Ton = 12000 BTU/hr = 3517 Watts

Did you mean to say "My estimate is 3,500 watts of electric resistive heat is about one U.S. BTU ton"? That would be correct. And it's not an estimate; it's the definition of the units.

No. I stated my working estimate for watts to tons is 3500 watts is about a ton. Being off 17 watts over many thousands of watts is meaningless and within any margin of error for the various devices, generators, and delivery systems my home uses.

Why the demonstration of hostility??

Read my message again. You said that 3500 W = 1 BTU. I simply asked for clarification, because that couldn't be correct. (I'm not talking about the 17 W. I'm an engineer, and know all about rounding, estimates, et al.)

As far as hostility is concerned, take a look in the mirror.
