I need to have my old boiler fixed - its a gravity system, with no automatic feed and no air eliminator. I would like to have it serviced and have these part added becuase I am hoping it will help with my gas bill. I have a remodeled house with all new appliances (except the boiler), new windows, door, etc. and I keep the thermostat on 68. Yet my heating bill is over $500 per month!

Does anyone know them name of a heating repair company in the area that is trustworthy and reasonably priced? Thanks in advance for any suggestions about a company or what I can do to curb this bill.

Is it gas or oil? For oil heat I would recommend Konowal's; for gas I would recommend Mangine's (if they can't fix it, they are usually good for recomending someone that can). Both are in the local phone book. Good luck!

Try Struse I,ve used them and they where great!! 215 483 0119

If, by "automatic feed" you mean a pressure regulator that keeps the proper pressure in the system so that, for instance, the hot water reaches the radiators on the top floor, I seriously doubt whether adding that and an air scoop would have any effect on efficiency. If, by "automatic feed", you might mean retrofitting a circulating pump, then , yes, that might help.
Probably the best thing you could do would be to bite the bullet and have a modern, high efficiency boiler installed. It would probably pay for itself eventually and in the meantime you'd be putting a lot less CO2 into the air.
And/or, install/upgrade insulation, especially in the attic.

Thank you. I found your advice most helpful. I do have one other question. How do you add insulation to one of these "flat roof" houses in Manayunk. I have not access to the attic. I am frustrated beyond belief with this heating bill. Its about a third as much as my mortgage!

I have a similar house to your's, and my roofs were insulated by the previous owner. There really is no "attic", per se, but only a space between the roof and the ceiling. What they do is cut a hole in the center of the roof and fill the space with foam insulation. Then the hole is capped with a vent (I've also hear that an attic fan can be placed here). It seems to work well in my home, with my 25 year old oil fired boiler system. My heating bills seem to be pretty reasonable.

Before having insulation blown into that "attic" space, make sure you don't have the old "knob and tube" wiring up there. Your house sounds old enough to have it. Burying knob and tube in insulation is a no-no.
