Hello all,
First time post for this guy...
I am in need of some advice.
I live in the Northeast and am pondering the idea of re-tooling the
mechanicals in the house. I now have an oil fired furnace for hot-water
base board heat and domestic hot water. I go through roughly 1,200 gallons
of heating oil in a 12 month period (2,600 sq ft home).
I have done some research on the "point of use" HW heaters and am
considering an electric type. I'd need to upgrade the electric service to
200 amp in order to do this ($1,500 - $2,000) plus the cost of the unit

If you go electric, and have variable rates, then you're better off
with a storage tank than an on-demand heater, because you gain more
in off-peak energy costs than you loose to cooling in the tank.

Esp. if the tank is inside the heated building envelope.
