Hi Everyone,
We just purchased a Metal building thats 4800 sq ft (60 x 80) of which 3000 sq ft is warehouse space and 1800 sq ft office. The ceiling height is 15 ft. Building has insulation in walls and ceilings & 2 overhead doors. Currently there's only electricity (3 phase available) in the building. The office is currently heated and cooled by a 1o year old york system, ducted with mostly flexible tubing throughout the office space. At this point, i'd like to start with the warehouse HVAC. My contractor has done a Heat Load for the 3000 sq ft and says I need 83K BTU's of Heat and 40k BTU's for Cooling. We've discussed several VFR systems.
At the moment my contractor is suggesting a Mitsubishi City Multi 8-ton hyper heating H2i heat pump PUHY-HP96TNU-A with 2 Inside Multi-Position Air Handler's Ducted PVFY-P54NAMU-E1 with Optional Electric Heat Kit
Some questions are;
Is it better to get 2 - 4 ton outside units?
Should we increase size of the Outside Unit to provide future expansion into the office space?
Will this be a very expensive way to heat the warehouse compared to oil or propane?
Will this system provide the heat needed on cold days?
Any advice is much appreciated. Thanks
