    Most of my contractors are insisting on the TT110 rather that the TT60.

  3. Upon oil to gas conversion, getting rid of the 275 heating oil tank?

    I have a 5 year old 275 gal heating oil tank that I need to get rid of upon my oil to natural gas conversion. The tank in above ground and in a shed next to the driveway. The gas contractors are...

    Ahhhh, thanks for explaining it in detail. I am enlightened. I'm going with the PTS60 with the Smart 40. I'm at peace with this choice. Thanks all for your help. The contractors all want to talk...

    It's about the recovery time, isn't it? I will have 40 gal of DHW to start. After depletion in your example, I would be getting 1.33 gal per min in the dead of winter if it is run continuously...

    One contractor said that with the TTPrestige 60, "you don't have enough BTUs to meet minimum flow rates. You're going to need at least 110k." On the spec sheet of the Smart 40 indirect, it says...

    I currently have a propane stovetop which uses maybe 30 gals a year @ $4.33 currently.or $130 per year. I also have an electric clothes drier. Should i bother piping natural gas to change the...

    Looks like I'm looking at the TT CC125s (aluminum heat exchanger) with the TT Smart 40 Indirect Hot Water Heater vs. Weil McLain GV90+4 with the Weil McLain AquaPlus 45 Indirect hot water tank which...

    R, I really appreciate your input. I'm going to nix the Navien CH210 Combi idea. The initial contractor came in with that and I asked him to rework the proposal with a AFUE 90+ boiler with an...

    That's what I'm citing as an added expense that makes going the mod-con route a better choice because you don't have to use your stack.
  11. Well then it becomes a cost problem because I may...

    Well then it becomes a cost problem because I may then have to line my Chimney stack for the lower temp gas venting which would be a prohibitive $1. Mod-cons have come down in price over the years...

    I need to get a min 90% AFUE to get the $750 rebate. Quotes for the TT Prestige Primax Excellence or a mod-con with an indirect is so expensive $$$ I am considering to buy a mod-con with a...

    From *removed link to HVAC Forum*

    Applying Brad's formula:
    BTHU = (Annual Fuel usage/0.6)*(house temp-design temp)*efficiency*fuel heat value)/HDDx24

    How do I calculate heat lost base on oil consumption? My energy audit says in 2012 I used 775 gallons of #2 diesel at 79% efficiency. The gov data says that my region had 4753 heating degree days...

    Another contractor is suggesting the TT Prestige Excellence PE110 boiler with internal indirect hot water heater. He likes it better than the TT Challenger Combi.

    One contractor is proposing a Navien 175BTU CH-210 Combi with tankless DHW or for $ more a Weil-McLain GV90+5 140BTU mated with an AquaPlus 55 Indirect. I'm think i can scale it back to a...

    The energy audit doesn't do a heat loss analysis. They do the door blower test and then measure the rooms and add caulking and sealing in the windows, doors, attic where there are leakages. They...

    I think the supply dynamics are forever changed for oil pricing. It will always be more expensive that natural gas IMO. We import more oil and we as a nation source natural gas which is in abundant...

    Does the 41,200 BTUs heat loss sound correct for my size house? Do I have to increase it for indirect hot water heating? One contractor suggested a 96K BTU ballpark whereas another proposed a 175K...
