Default efficiency of +20 year old Weil-Mclain oil boiler P366(HE)?

How do you make hot water? If it is the typical tankless coil, it is very
inefficient for that use. Do you hear the boiler kicking on to keep the
water hot? Terrible waste of energy. Indirect fired water is far more
economical and a good tank can keep water hot for a couple of days if not
used. It used to bug me to be laying in bed on a hot night and hear the
boiler kick on just to maintain temperature. No more. My basement is much
cooler now that heat is not wasted.

Yes, I have a tankless coil that dumps into an electric hot water
heater for temperature avergaing, in which the electric elements never
kick on. I assume that I'm saving money vs using the elctricity.
Even though electricity is close to 100% efficient in heating (no flue
gases), it's expensive.

I'll look into indirect if I change out my boiler, though I bought the
electric water heater only 4 or 5 years ago. Right now the only oil-
fired boiler good for the 30% tax credit in my size 100,000 BTU/h is
the Buderus condensing boiler. I'm looking for prices, but I'm
guessing these are very pricey. I can get a Weil-McLain at 86% or so
for about $2300, including a tankless coil (which I may not want now,
after reading your comment) and burner.


Why do all you people want to heat hot water?
