    LP boiler would be a great choice

    I would just be concerned about running piping into an attic to feed an air handler.
    Since your gonna need to feed piping (probably PEX tubing ) up to the 2nd floor., I would look into running ...

    An outside exhust

    will cause a negative air pressure condition and draw in cold or hot outside air into the rest of the house.

    Throwing hot air into a furnace return might help your heating bill in the winter, but...

    trouble down the road

    Pain to replace. And roof leaks will be an issue. for 1500 sq feet, 2 mini splits should do a nice job.

    Didi you ever mention your electic rate

    I thin you just made a big mistake with electric tankless. Using electric is the last
    resort energy source for a cabin out in the woods where getting oil or propane trucked in is a pain or too...

    Instead of wasting money on all these dangerous space heaters. Get the fan coil fixed. The landlord would probably prefer to fix the unit then allow you to burn the whole bulding down.

    Maybe a side venting condenser

    I put mine under a deck.
  7. I guess you have steam

    I think you're crazy to loose that for hot air. Spend the money on insulation. Tune up the boiler to max efficency. Save on just getting a split AC system with attic duct work.

    I agree

    If you plan on remodeling and adding insulation, etc. I would do that first. Why get a bigger boiler then you need? Where's your oil tank? Think about the cost of removing or abandoning an...
  9. your contractor must be a radiant expert

    Heat loss calculations must be made to exactly know how much tubing will be needed (hopefully there's enough room) to cover the heat loss without overheating the floor. Very important to know what...
  10. Temp variations with the NuHeat

    The hydronic floor warming will always be at a different temp then the NuHeat.
    I'd shut off the Nuheat and tube the whole area under the tile floor. I would have a timer in the winter months to...

    You should get an efficency rating when the boiler is tuned up. Is this a steam boiler?
    How big a house? What type of radiators? You can get 40 years+ out of those old 600lb cast iron mosters,...
  12. I agree on the floor

    Probably part of the same slab as the garage. I would use a poly foam based
    padding and put comercial carpeting over it. Or put sleepers down, insulate, then put 3/4 plywood and tile over that. ...

    if it's truely condensing

    you have it set up for cold start correct? I don't see an issue. Better for the boiler to run all year. You'll probably need at least an 80 gal indirect. Or look at getting an ergo max or other...

    Anyone can rattle off

    efficency numbers off a brand's literature, but show me a duct systems that's really
    98% efficent. Doubtful. Let's not forget to compare the electrical use of an air handler
    blower compared to a...

    Boilers yes

    No hot air in Europe, Get a thermopride if going hot air oil. I would go hydro-air.

    But

    if the loop is too large, and the last section doesn't get warm, then spliting could help. If you're changing the layout or use of the rooms, splitting could make it more comfortable as each aone...

    I would price out

    a single zoned AC system with the boiler and indirect HWH with panel rads or high end baseboard. Where's the second 90+ furnace gonna go? In the attic? Not recommended.

    If you want comfort

    Leave the ducts for AC. Panel rads for heating.
  19. I think

    the units are in series, the 2nd unit might not be used too frequently. 12 cents sounds high to me, but if the system comes on infrequently........
    I assume when the concrete mass starts to cool,...

    also check

    www.mysoninc.com

    They have some fan coils that could be cost effective to heat the kitchen
    if you don't have the wall space.
  21. Must help keep radiant costs down

    I guess you have cheap electric rates. Some building codes don't allow equipment thats not rated as heating equipment to be used. I guess as long as the output can match the heat loss you're good....

    High end homes use hydronic heating

    Sounds like a high end house, I wouldn't want 5 exhausts vents comming out all over the place. Many gas lines too. A mod-con boiler can ramp up as demand increases from multiple zones. The air...

    what makes your domestic hot water?

    Maybe ditch the HW heater and get an indirect or put a buffer tank on it.
    Might eat any money you thought you were gonna save on the used boiler.

    a five minute burn isn't too bad

    I'd see if the differential can be set wider . Let the water temp drop 15 or 20 degrees before firing again. You might need a new aquastat as the basic ones have a fixed 10 degree drop before...

    boiler. Spending all that money for when you're NOT there is crazy. Too fancy a boiler might trip out and now you have a frozen home. Get a small low mass boiler that you can cold start Burnham LE,...
