Our boiler is a direct vent unit. There is a fan that pulls warm air into the boiler directly. And the hot gasses flow out another pipe to the outdoors attached to the side of the house. There is no fan on the outflow pipe, but I'm not sure if the positive pressure from the inflow of air helps to "push out" the flue gasses. So, if the boiler isn't running, the fan is not on, so any heat loss through the exchanger will mostly be radiating into the basement, which is directly under our kitchen.
As far as I can see, there is no flue damper, but there is a vinyl condensate drain line for the flue pipe.
So, do you agree that it sounds like the best bet may be to go with option 1?
If we were to use an electric water heater...I know GE makes an 80 gallon one, would it be better to seal the water pipe connections and instead use the element ports (since I'd assume the elemnts would have to be removed anyways). Or just use the water pipe connections? Also, we'd have to put in a T&P valve. It would be 30 psig, but would it have to be rated like the boiler one at 510,000 btuh?
Thanks again for all your advice.
