Which heatings system should I go with?
Little background on the house. 2,800 sq ft 4 level house in Massaschusetts. Current set up
Basement finished (800sq ft) - hot water loop
1st floor (1,000 sq ft) steam radiators with additional 300sq ft of family room hot water loop
2nd floor (1000 sq ft) steam
Attic finished (600 sq ft) steam
My steam boiler is old utica system (30 yrs) and runs on Oil. The house has old single pane windows, with storm windows, and no insulation in walls/roof). The oil cost to heat this house with the last owners was $3000. But I have small kids and I am afraid my cost will be $4-5k. That is crazy money.
I am considering several opetions.
1. Replace the boiler with a new boiler that will use gas ($6,600).
I will have to pay about $4,000 for boiler replacement, plus $600 for hot water boiler replacement, but I would have to re-line the chimney $1,500, plus above ground oil tank removal $500. For a total cost of
If I go with this option I would end up with a 80% efficient system, banging in the pipes, uneven heat, and no separate zone set up so at night I would be heating the whole house.
2. Replace the entire system with hot water baseboard
$3,000 labor, $2,000 boiler, $3,500 parts and supplies for a total cost fo around $9,000
I would get an goof efficient boiler in the 90%. If I get one with 95% I would get the tax credit. Will get several zones in the house, even heating. No banging in the pipes when heat it on.
3. Install a Central Heat and air
This was our preferred option, but the estimates came around $20,000 to $25,000 for a two zone, two furnace system. They said lot of carpentry work escalates the project since the attic and basement are finished. I recently discovered that there is room in my attic to run duct so I am hoping this would cut some of the cost down. I am puzzled what exactly drives the cost for this instalation so high. I glanced on a website that shows furnace prices and saw that a 3.0 ton 15 seer double stage Diamond Air furnace with Condenser, Gas Furnace, Cased Evaporator coil, primary drain pan costs $2,300. Two of those with shipping would be $5,000. Let's add another $2,000 for parts, gas line run, electrical work. How much could duct work cost? $3000? Still, that makes us at $10,000. Is somebody charging me $10,000 for labor?
I think that if I can get the central air and heating system for $15,000 that would be ideal, but otherwise I am leaning on having a hot water baseboard system, although that means installing a whole new system.
