Seeking formulas and laws of heating

Randy Schuyler

I'm in the process of starting an online community similar to The Wall, but with the focus being water heaters.

For the logo, I envision something like a diagram of a water heater with equations and laws (such as Moore's Law, or the Peter Principle) bubbling around inside.

Does anyone know of anything like that?

You are kidding, right?

We do that here already.

You prospecting The Wall?

Unless of course you're contemplating competing with RadianTec? He could use some help.

How much discussion can you have about a 40-gallon water heater? Home Depot sell 'em for around 130 bucks.

Isn't that all we need to know?

All you need to know

About 20 years ago, my best friend and mentor, Larry Weingarten, started pioneering a service to water heaters to make them last longer, and function more efficiently and safely. He also, with his wife, wrote a book that both Dan and I sell -- The Water Heater Workbook. I suggest you get a copy to learn what you REALLY need to know. However, a fair amount of that information -- although by no means all -- can be found at www.waterheaterrescue.com, along with some of Larry's antique water heaters and some of my scarier inspection findings. I'm finally getting around to fulfilling a long-term goal of creating an online forum to bring together builders, apartment folks, plumbers, maybe architects and certainly the public. Is that clearer?

PS -- I have no association with RadianTec...... And Larry laughed when he realized I'd used Moore's law as an example and suggested maybe I should have used Boyle's law (sigh)....

with the life expectancy of engineered equipment these ..

days perhaps Crooks Law might be appropos*~/:) je ne sai pas d crois

DanHolohan

And maybe

we'll wind up with fewer tanks in landfills, and less energy use in this country.

As you know, Randy, you and Larry and Suzanne have my full support for what you're doing. Thanks.

Be nice to see

you address and present pictures of water heaters used for radiant. I feel many time bombs are out there with the low operating temperatures these are installed at.

also the manufactures warranty position on installation of WHs in closed loop applications needs to be questioned.

Perhaps a page just on WH radiant applications.

Good luck with the project!

Consumption - Utilization = Waste

for the record...

AO SMITH has one of their standard water heaters providing their office hot water for over 30 years, and all they do to it is change the anode every 3 years, and flush out the scale with a ballvalve on the drain twice a year - thats it!!! - at least the what the lady that sent me my last anode claimed, something to think about, before you mount a water heater with no vertical service clearence

Randy,

I got to open my intro college physics book, one of the finest texts I've ever learned from. Here are a few that seem appropriate. I've written out what they mean now. As soon as I can, I will scan in the equations so you can see what they look like.

1)
heat = mass * (integral from t1 to t2) heat capacity * dt

For the purists who know that the heat capacity is not constant with temperature. This seems like the most appropriate formula for a hot water heater. For the engineers, it reduces to heat = mass * heat capacity.

2)

change in internal energy = heat - work

the first law of thermodynamics

3)

pV = nRT

pressure * volume = moles of gas * gas constant * temperature.

The ideal gas law.

4)

S = k ln w

Entropy = boltzman's constant * natural log of disorder


enjoy, jerry

That is water heater maintenance in a nutshell. And nobody does it. We want to change that.

Randy Schuyler

The Wall is really the proper forum for that. Waterheaterrescue.com is more about longevity, maintenanace and safety issues for water heaters used to heat water, not in space heating applications.

Randy Schuyler

That's "je ne sais pas quoi." :-) Et vous pouvez lire de chauffes-eau egalement en francais, comme en anglais ou espagnol

New web site.

Hey Randy, Does this new site your starting have crack transdermally administered through the computor keys like Dan does? If so, count me in. I was wondering why the "Wall" was SO addictive....Good luck!..Robert O'Connor/NJ

Tu sabes mas amigo:)

such subtilties are not wasted on us one product operation and installation guide i picked up about 7...8 years ago was written in like 17 different languages ) I am miserable at best in a bunch of em mostly stuff you learn with working with others and hand me the martillo y clavos type stuff. i can pick n poke in mandrin Chinois aussi:)

Weezbo

just thought we might take a lookat the new site...

my mouse in my pocket and i are home oday hiding out from no heat and any other calls while the sheet rockers mud tape n texture ,sand prime and paint the new home we are doing:)

Einsiedler_2

I'll take 2

if home depot is sellin for $130 - I'll take 2.
(the new FVIR heaters run much more than that here..)

Sensible heat rate equation is one to use..
Q=Wc(Delta-T)


cheers!

You Just gotta take alook at the ladds efforts!

He has some antiques that would look Great! think about it.....That Rudd sure would be the killer deal. the wesix has inner beauty and the old pump showers bought back chilhood memories of my friends home and his dads collection of functional weird things..they also had this Tube record player that took up half the back yard:)
