Ok, thanks to Jim's answer on my Boiler thread http://www.terrylove.com/forums/show...Series-Boilers I know I want to go with a "modulating" boiler.
Now let me layout my project, I really need help thinking this through.
In summary we are going solar and will be replacing our existing 120,000 btu oil burner with a electric boiler system.
We are also "thinking" of installing a 3 ton air source heat pump in our downstairs living room/kitchen/dining area (one big room 40' x 30') with open stairway to second floor.
Regardless of rather we do the heat pump or not, we definitely want to get rid of the oil burner.
Currently we have old 3/4" iron pipe baseboard in series around the downstairs and upper level with two 24" x 30" cast iron radiators embedded in the wall between the living room area and a 20' x 30' garden room that also has radiant heat in it's tiled floor. The radiators are open to both the living area and the garden room but enclosed on the top and sides.
Now this is where it gets dangerous " I am thinking "
about replacing the oil burner/boiler with an electric boiler. Is anyone familiar with electric boilers? Any suggestions/warnings?
I want to split up the heating into three zones so I'll be looking for help in designing hook up for that but wanted to see what you had to say about the electric boiler and if you had any suggestions.
Oh I formally had a plumbing and heating business so I will be doing this work my self.
Thanks for your help.
