Gas + Electric Condo VS All electric condo
Hi I’m doing a development in Brooklyn between 2 houses and wanted opinions on whether or not a minisplit heating and cooling system would be enough to heat each apt. NYC does get cold but since its a multifamily building we are only exposed on the right and left sides.
Originally we were going to have a minisplit system that has heating and cooling AND baseboard heating for all the units but after talking with the GC and architect, I can save somewhere between 100-125k in project cost alone if we completely remove the baseboard heating, and make the entire building electric and it will quicker to build without having to wait for national grid for gas hookup. Instead of the combi gas units we would then use an electric Tank HWH which is significantly cheaper and have less penetrations on the roof for exhaust from the HWH so less possibility of roof leaks.
Anyone have opinions of having each apt use only the minisplit heating and cooling? We are using 9K BTU wall mounts from Mitsubishi for the bedrooms and living rooms (2 per apt, each apt is 1 bedroom/1 bathroom) total 550 sqft. These will be rentals so we need something reliable. For the larger apt, we are using the ducted minisplit and using 9K BTU for the bedroom which is about 150 sqft, 9K BTU for the Living room 350 sqft, and 9K BTU for the 400 sqft basement. All apt ceiling heights are around 10 feet and all these units will be hyperheat and placed on the roof so I am hoping it wont get cold than -13F since that is the coldest operating temp for the Mitsubishi hyper heat minisplit models. Just looking to see if anything uses this only for the entire home and if they think it is sufficient for Heating and Cooling.
