Our current electric water heater needs to be replaced. I suspect the bottom is full of sediment and the whole thing is probably coated with minerals from our hard water.

I've never heard of a tankless water heater using heating oil. Maybe it could be found on the east coast somewhere. I wonder about heating oil soot clogging up the heat exchanger. Ours runs off of propane. Both put out up to 6.1 gpm of hot water. I've said this before in threads about tankless water heaters, but we use .17 gpd of propane, so I have my 250 gal. tank refilled every two years (usually filled to 80% and refilled at around 20%). There are only two of us, so usage isn't as heavy at a family of five. Our usage is the usual things: bathing, kitchen, laundry, cooking, etc. The circulation pump circulates the hot water on a loop. So in the case of the bathrooms in the rear of the house, when you turn the pump on and open a shower valve, the hot water in the loop circulates to that valve (or any/all open valves).
