Commercial water heater in home

With 91 gallons of hot water sitting in a well insulated tank, he won't need to heat water for quite some time during a power outage.

The floor can, it is a concrete floor in the basement. But taking it down to the basement will be a pain.

My furnace has a 6 inch flue. My current water heater has a 3 inch flue, IIRC, and joins the 6" furnace flue very close to the heater.

Yes, this is badass, 199,00 BTU.

What I hope is that I can use it to fill my inflatable pool with warm water.

That's OK, I am not worried, I can survive without hot water, and also I have a well working 20 kW generator.

Thanks for your thoughtful input, this is exactly what I was looking for.

Silly Canuck. Filter/soften that water before heating it, eh?

Oops, except that there won't be any pressure to use it...

I do. A lot do not. .

Depends - If he's on a well, no. On city water it's never been a problem here.

I can live with kettles of water heated on the stove. It can be poured into the washing machine or the dishpan, or the modified garden sprayer I described earlier to take a hot shower. When I was a soldier and active outdoorsman I learned to brush my teeth, shave and wash up with warm water in a Sierra or canteen cup. jsw

Right, but you still need water pressure to supply water. I'm working on finding a split well cap which will let me to sink a manual pump next to the downpipe of the submersible, allowing me to pump water during a long-term power outage. If your big-city power generators at the Water Works are stolen or destroyed by the angry crowd (who are pissed at the power outage; logic has no place during a riot) you'd still be SOL.

Don't you have a generator?

No, and in a crunch, I wouldn't want one. It draws the ire of too many people, both from the noise and from the "You have power and we don't; GIMME!" sides.

Serious point to keep in mind. Just as news of where there is work, the sound of a genny set, or the smell of meat cooking, travels

- and attracts people. Hungry people who may lack the social niceties.

Around here everyone has them, and if theirs won't start I'm gonna be fixing it anyway, in trade for a meal or a shower or plugging in a long cord. I draw less than 200W on average, 24/7..

Generators are considerably quieter inside a 3-sided box of fire-rated suspended ceiling tiles, stacked freely like a house of playing cards. I also tried an external muffler of fiberglass pipe insulation but it didn't help, most of the noise radiates from the engine.

In at least one nearby town the sound of a generator attracts fire inspectors.

For my well I got tired of spiders or whatever falling in the water and testing positive for e. coli. So I removed the typical cast aluminum cap and added a couple tapped holes, one for chlorine and one for a sintered bronze vent. I replaced the cap, sealed it to the casing and sealed the wires going into the cap and since have had no more bacteria problems. Surely you could remove your cap, bore it, and then weld a pipe fitting of some sort to it. Eric

Your 3/4" gas pipe into the house may not be large enough to supply both the nfurnace and the water heater. At my last house I had to change to a 1" pipe from the meter when I added a couple extra gas appliances. Eric

Never had a problem with either type around here.

IIRC typical gas water heaters fall into the 40,000 btu range... IOW, his meter and gas piping is in all likelyhood WAY too small.

Sure, and when I was a kid a lot of people took a bath on Saturday night. Saves even more water.

That made sense before central heat and antibiotics, when catching a bug could kill you.
