ok, my source of heating my domestic hot water is a oil fired hot water

my problem is it takes way too long from the time I turn on my hot water

on, water has to flow though the coil in the furnace and then flow upward to
my taps. *What I want to do is put in a non-heated storage tank (about 40

The tank would obviously be insulated very well to keep in the heat. *Temp

My storage tank is an old oil fired hot water tank.

I can not see how what you have now, even if it was working correctly
is an efficient way to heat water in summer when the boiler is off.

An oil-fired furnace that provides domestic hot water is in effect an
instant water heater. They only keep a few gallons of water hot when
idle and can easily keep up with showering and washing clothes.
Another benefit is the furnace stays running year round and doesn't
collect moisture and rust out.

A
storage tank will just cool and waste energy if you pay to heat it to
180-190.

That is exactly what an electric/propane/gas water heater does/is so
it would be just as efficient and ignoring the sillyness of last year
oil is cheaper than gas and way cheaper than electric.
