I am trying to decide between two different installation companies, both recommend same ton unit but differing loop fields. any suggestions?????: Proposal #1: Waterfurnace 5 series 4Ton 6pipe loop in (2-300ft trenches, 3ft wide 5ft deep heavy clay soils) 3/4"pipe (3600ft total pipe in ground) Proposal #2: Climatemaster Tranquility 30 4Ton 4pipe loop in (2-300ft trenches, 2ft wide 6-8ft deep heavy clay soils) 3/4" pipe (2400ft total pipe in ground) load calcs: heating 34,268BTU, cooling 30,165BTU
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 $37,600 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.
