We are more or less carbon dioxide machines...
They’re escalating the insanity at an intentionally dizzying rate.
My water comes out of the ground at 42 degrees f year round.
Must not be in southern Arizona, then. I don’t think even deep wells run that cool, much less piped water.
Yes, you’ll just need a huge electric service or huge gas piping, depending on how it’s powered.
Tankless water heaters cannot be installed without a huge expense because of that.
I put mixing valves in because my toilets would sweat gallons of water all over the floor in warm weather. Both hot and cold water fed the toilets.
They know human psychology. They pray on our fears.
“Build the wall”. Sure we want that, but guess what?
Walls can keep people in as well as out.
The day is coming when that trap will be set and it’ll be too late by then.
Not exactly.
A condensing heating device is simply one that extracts enough heat to lower the exhaust flue temperature into the water condensing range. Different sources make different claims, typically from ~250F and lower, some can approach an exhaust temperature slightly lower than the discharge temperature of the heated media.
And for some fun check the recommended temperature to prevent Legionella and the max safe hot water discharge temperature.
Lower domestic hot water temperatures are more efficient but tend to promote Legionella.
A friend of ours pumps water from the bottom of the Chattahoochee River into the marble floors of his house in the summer for cooling. In winter they have a diversion valve that recorculates the water to solar collectors that heat his indoor swimming pool. It’s nice to be rich. Warm floors in the winter. Cool floors in the summer.
They use a collection tank and lift pump into the sanitary sewer.
Mine was installed 17 years ago, in my condo, with existing 110v electric and same gas service as tank heater used. Recouped the $5,500 cost in under 6 years.
I had a small tankless unit installed in my Nursery/Garden Center Main Building Office, when I built the 20ac facility, in 1990. Cost was about $1,000 during construction.
No need for anything unusual — unless you’re planning to supply a whole condo or commercial complex, and they get better-performing units, every 5 year cycle, or so.
Do we really need more regulations? How about letting the market set efficiency standards? If enough people want greater efficiency then the market will provide. The government is certainly not efficient in anything they do. They are just a bunch of over paid lazy asses that never built a damn thing in their lives. It’s time that we regulate government and fire about 800,000 federal employees when we shutter massive portions of government. Let’s see if they can survive in the real world. I really don’t care if they do or not.
And water heaters last about 10-15 years.
The question is how much government bullying will the American public take? Maybe lukewarm water will be the straw that breaks the camels back. Truth be known the government has zero authority for any of this crap and it’s only happening through brute force and ultimately at the point of a gun if necessary.
Oh, it will be like the low water toilet that won’t flush crap.
These bastards are at war with us.
Oh great. A "water-saving" hot water heater. I can't wait. Water-saving toilets and kitchen faucets worked so well. I think I'll just beat them to the punch on this new technology, and replace the 1 inch water line coming in to my house with one that is 1/4 inch.
U.S. Department of Energy ,LOL the price of electricity will go up to cover the loss
A very small tankless unit (suitable for a 1 bedroom, 1 one bath condo) might be OK with the gas service supplied to a regular tank heater, which is around 30K BTU.
But a small tankless unit won’t be able to provide a high temperature rise at high GPM (this might be OK in places in the country where the incoming water temp is higher).
In other words, the colder the incoming water, the higher the gallons per minute being drawn—the colder the water that comes out of it.
So if you want to be able to draw 4GPM with a 40F incoming water temp (common here) and an 80F temp rise (120F out), you aren’t going to be doing it with a gas supply line capable of 30K BTU or a 30 amp 240V circuit. Try more like 150K BTU or a 120 amp 240V circuit. (usually spread across 3 40 amp circuits from what I’ve seen).
Those are expensive to install.
We’re from the government and we’re here to help.
