    We have narrowed it down to 2 proposals for our new construction home. All are 3 zone (basement, 1st, 2nd Floor) with 1700sqft in the basement, 1700sqft 1st, 900sqft 2nd. Closed cell spray foam insulation, and good quality doors/windows. Load calculations: heating 34,268BTU, cooling 30165BTU. Richmond, VA location

    Proposal#1:
    Waterfurnace 5 series 4Ton
    intellistart, intellizone 2 (3zone), power open/close dampener, hot water assist w/tank, 6pipe loop field with 3/4" pipe in 2-300ft trenches 5ft deep 3ft wide, alpine pure ERV
    $37,4567

    Proposal #2:
    Climatemaster Tranquility 30 4Ton
    iGate, vFlow, de-super heater w/ tank, 4pipe loop field with 3/4" in 2-300ft trenches 6-8ft deep 2ft wide, Honeywell pro8000, power close/spring open dampener, ERV

    As you can see price is not a deciding factor, but the loop design and equipment looks to be the main differences. Any thoughts????????????????????

    Lower average depth and more less foot per trench foot of pipe will mean the 4 pipe system performs very well cancelling out the additional footage of 6 pipe trench. get references and go with best dealer.
