On our Electric Bill each month we pay a $3.95 fee that covers up to $500 worth of work if needed each year which includes installing a 50amp fuse if we needed it. Everything after that $500 is billed at a 15% discount. We had them come out a few months ago to replace a GFCI outlet and about a year ago to fix a ceiling light fixture box that fried, all part of the $3.95 a month fee. So for us the fee for that would have been basically $47 which we paid for in monthly installments of $3.95. If we had called an electrician to do both of those things would have cost probably at least $100 for each time coming out if not more. The gas company does install gas line to the house and inside the house and for each branch they install to a stove a fireplace a furnace a out door grill etc is more profit for them for many many years to come, in fact it is virtually their entire business. Lets say the cable company would charge you $1300 to run 30' of cable to your house and hook it up. Time Warner would obviously be out of business today. Instead they charge a very reasonable fee, many times its actually free, all of their service is free if you have a problem. The only time you are charged a huge fee is if you are just one person down a long country road. But if you need to be hooked up its usually free because amazingly they want your business. The gas company gets virtually ALL of its income from selling you GAS. It would have cost them maybe $30 tops to send someone out and install the line and could have charged $100 and made $70 profit plus now have that extra line of gas that will be there until this house gets bulldozed over probably 100 years from now. $3-$6 a month for many many decades is worth making $70 "profit" for an hour to most businesses. Just got our gas bill today and it was $5.12 for the stove this month, my wife had to admit to me that she left the stove on for about 15+ hours 2-3 weeks ago when I hurt my back and she cooked. :) That is how business works, especially a service business that sells you a product every month, like cable, gas, etc. Like Caddy just stated, the LP company comes out and rents him/her a very expensive tank for .80 cents a month, installs it for free, then comes out to timbuktwo to deliver propane when you need it and the only charge is just for the GAS because they want your business and like the NG company their business is selling you gas every month. Pretty simple concept, for most people.

Another take on the induction question with a little sprinkle of humor. https://www.eevblog.com/forum/chat/induction-cooking-emf-magnitude-vs-other-things-missus-is-a-bit-concerned/  Tim says, Ugh... If she's worried about cancer... dump her now? There's no convincing someone like that, to understand statistics and significance. At least that I've heard of. If you're looking for the opinion of an EE, I would gladly give you my opinion on the subject -- if you'd like it in writing, I can even sell your wife a certificate saying as much! Maybe that wouldn't help. I don't know. What are we talking about, anyway? Cooktops aren't always-on. They're either off until turned on, or pulsing infrequently to check if a pot is present. The RMS EMF at the surface is not very large either way, when not actively heating something. When heating, it's only large under the work being heated. EMF drops off rapidly with distance. If your wife is so strange that she finds it enjoyable to read books while laying over the cooktop, I might be concerned, but only for mental health reasons, not for EMF reasons. Or if shoving her head towards a pot that's being heated, I would be more concerned for safety reasons, and then mental health reasons... There are biological effects of EMF, but not at these field strengths. Not by orders of magnitude. The primary effect is simply dumb old heating. Diathermy machines, microwave ovens, and the military's ADS, operate on this mechanism. There is no biological effect beyond heating (obviously, too much heat and you cause burns, but that's not unique to EMF). Strong pulsed fields can induce voltages in neural tissue (transcranial magnetic stimulation), which do have direct neural effects, but these are temporary. Anything that produces fields with too little energy to cause noticeable heating, or pulse peaks strong enough to cause noticeable induction, is completely and utterly inconsequential. Example: ESD can have quite large (peak) EMF, but is over very quickly, and delivers very little energy (on a human scale). (Anyway, sparks are well known to cause people to involuntarily jump or twitch. But again, that's just a neural stimulation thing, nothing more.)

"For comparison, the cheapest Rheem gas 40 gallon hot water heater in Home Depot has a 36 GPM recovery." Sure. For many products, performance and price go together. Lower price, lower performance, and the opposite is also true. I've learned that a quick assessment of relative recovery time can be done by comparing a product's BTU output, in thousands, to its size in gallons. A 50 gallon tank that has a 45K BTU or less capability will recover much slower and provide less hot water in an hour than one that has 50K BTUs or more. I looked quickly and found a "quick recovery" 50 gallon tank with a 65K BTU burner and maybe even larger ones are made. And, of course, continuous hot water at lower flow rates can be had with an instant hot water unit. Or connecting two tanks in series also will do the same thing. That might be a clever thing to do for an all electric house with more occupants needing greater capacity at times - two heat pump water heaters connected in series, the first one remaining in heat pump mode most of the time to supply warmed or hot water to the second one used in hybrid mode, that feeds the home's hot water pipes.

JuneKnow, you do not know what you are talking about. The contractors are NOT talking to each other about how they can fleece me. That is absurd. The problem is that I don't know what are the correct installation methods. Most homeowners don't! We have to trust people because they are the pros. AND... I am not looking for CHEAP contractors. My roofers drove over two hours away because they were the ONLY licensed roofers I found. Oklahoma did not require roofers to have a license until 2011 or 2012. BUT, no one in Oklahoma does anything about the illegal contractors out there. I have complained and called the Oklahoma licensing board. This is a Good-Old Boy state. Drywall contractors drove from the metro area and screwed up my drywall seams. Appliance repairman drove from the metro area and my oven needs repaired again. He also scratched up my cabinets. Pool repair guy came from metro area and screwed up my pool liner. The list goes on... JuneKnow, you have NEVER been helpful with your comments. Many people have posted to ignore your comments. You seem to have no purpose except to degrade homeowners who are doing the best they can with limited knowledge. I don't know why you like doing this, but, please don't bother answering my posts. I can live without your unhelpful and asinine comments. I don't accept incompetence...and I don't know people are incompetent until they have done the work incorrectly. I don't know that the work WAS done incorrectly because I am not an "expert" like you. You seem to believe that HOUZZ is only for "pros" to get jobs and resent anyone who does DIY. It is also for homeowners to ask questions. That is why Garden Web forum was added to HOUZZ. For everyone else, I am beyond frustrated right now and beyond pissed at JuneKnow, but I apologize to anyone else. Weedmeister, did you have a chance to look at the pictures of the hot water tank? Ron, thanks. I had the electrician back out to question him. He says the boxes with blanks inside the wall are legal and that any inspector would approve them. I called another electrician and paid him to come out. He said they are legal because the house is "grandfathered in". His exact words. A third electrician said "because the work was minor and no walls were moved or added that the work is grandfathered in." His exact words. I don't trust anyone now. I will call the electrician that I used before he moved two hours away and beg him to drive down here. I hope he will. He fixed a lot of illegal electrical work in 2012 before he moved away. I think we spent over $42,000.00 just for the electrical work that he did. Part of the problem is that apprentices learn "on the job" here, so they think they are experts. If the licensed contractor that they learn from is incompetent, then the student will be too, but they don't know they are incompetent. The homeowner doesn't know either.
