I need a complete design package for a small, horizontal closed-loop geothermal system that will cover heating, cooling, and domestic hot-water production for my 1,250 sq ft home in Colorado. The house already uses forced-air ducts, radiant floor zones, and a few baseboard heaters. I want the new ground-source heat-pump system to tie into this existing mix while providing even, whole-house cooling throughout the year. Your work will include: • Manual-J (or comparable) load calculations based on local climate data • Horizontal loop field sizing and layout, including trench depths, pipe sizing, antifreeze choice, and estimated excavation footprint • Heat-pump specifications with COP/EER data, desuperheater integration for hot-water assist, and any buffer or mixing tank recommendations • Schematics showing how the unit connects to the ductwork, radiant manifolds, and baseboards, including control strategy for simultaneous or staged operation • A concise material list and installation notes detailed enough for permitting and for a local contractor to price and build • Any performance estimates or energy-savings projections you can derive from GLHEPRO, LoopLink, or similar tools The package will be considered complete when the drawings, calculations, and equipment schedule are clear enough for submission to my county building department and for on-site installers to follow without further clarification.

My immediate steps will be. Run the Load Calculations: Determine the heating and cooling loads for the 1,250 sq ft layout (accounting for the ICF walls and Colorado climate). Size the Heat Pump: Select the exact size/model of the ClimateMaster Tranquility (SW) water-to-water unit based on your load calculations. Design the Loop Field: Calculate the required pipe length and trench spacing for the 30'x40', 12-foot deep pit backfilled with sand, ensuring it can handle the heat transfer for the selected unit.

Hello there! Could you please share the home’s location/county, floor plans, construction details, and available HVAC equipment information so I can establish the design inputs? I can develop and organize a complete geothermal concept package covering load calculations, horizontal loop-field sizing and layout, heat-pump selection, domestic hot-water assistance, hydraulic integration, controls, equipment scheduling, and installation documentation. I’ll coordinate the proposed system with the existing forced-air ducts, radiant zones, and baseboards, while addressing whole-house cooling and staged operation. The package can include calculated design assumptions, loop/trench layout, pipe and antifreeze specifications, equipment schedules, schematics, material list, installation notes, and performance/energy estimates where the required inputs and approved calculation tools support them. I’ll clearly document assumptions and identify items requiring field verification or local professional approval rather than guessing at site conditions. Because this is a mechanical system intended for permitting and construction, final engineering responsibility, code compliance, and required professional sign-off should be completed by an appropriately licensed Colorado professional. Please feel free to message me so we can discuss the project in more detail. Best regards, Damien Bartlett.
