regular 40 gallon hot water tank BTU vary anywhere from 34,000 btu to
75,000 btu. the higher the BTU the better.

Because we ran out occasionally we went from a 34,000 BTU 40 gallon
tank to a 75,000 BTU 50 gallon tank. I wanted a 75 gallon tank but it
wouldnt fit the available space between toilet and furnace.

Tankless tends to be a hot topic here........ from inadquate heat, =
cool showers if you live in areas that freeze in the winter, no hot
water at all in a power failure, if the tankless uses line voltage to
operate, no hot water with valve just open a little, super expensive
install, needing new gas line and occasionally a new meter. teenagers
given unlimited hot water might live in the shower. expensive service,
tankless are complex and require occasional service, standby losses in
current tanks is actually low, and stanby losses help heat your home
in the winter, so most of the heat isnt really lost. life is full of
sytandby losses, tv, cable boxes clocks etc etc. anything that draws
power when not in use is a standby loss......

your old tank is probably full of sludge decreasing its hot water
ability.

a new tankless will cost a fortune.......... 3 to 4 times a standard
tank which is highly reliable.

so lets talk tanks

upgrade from your old 40 gallon probably 40,000 btu to a 75 or 80
gallon 75,000 btu will likely give you about 4 times or more your
current hot water capacity. and in its life probably never need
service

you double the gallon capacity and double the burners BTU rating,
roughly 4 times the hot water.

no more cold showers

Here we go again the same missinformation, with 90-100f temp rise
offered you cant have a cold shower, I cant shower at over 106f but my
unit takes 35f water and heats it to 125 if I was to be wastefull.

Mine has battery ignition and regular vent-No A.C. But I have a
generator for my home for heat.

It took me 5 hrs to install, but I guess thats "super expensive" for
you. I put in 3/4 gas but that was only 1 hr work, again easy and
cheap, my meter is original.

Tankless require no "service" but tanks are supposed to be flushed
every year.

20% of your loss is waste-up the chimney and out, of no benefit to
anyone but your gas supplier since true overall efficency is near
50-60% in " Energy Factor" proven ratings

I paid about 500$ for a Bosch 117000btu unit, I get a FOUR year
payback, I hardly see the 3-4x cost of waste, I see I am saving money

Tank, loose efficency every year due yo scale settling over the
burner, just as my last tank had over a foot of scale at the bottom,
its efficency was probably reduced 20-40%, tankless dont do that, and
its easy to pour lime away through mine. You cant do that with a tank.
