Multi-Family Development in Central CA. Q about Heat Pumps

[Account Closed]

Hi all,

Working on a project in Central CA and have the option to avoid bringing natural gas on-site if we use heat pumps for water heating and space conditioning. The on-demand units need less space, but require more annual maintenance in order to avoid them calcifying. The heat pump units require more space, but there would likely be a savings in the range of $500k for the project. About 200 units here.

I am trying to figure out how to quantify if the annual maintenance would be more efficient then bringing natural gas on-site.

Cheers!

I live in the north east maybe it is because it is cooler here, but on the big multi family units here they use a direct vent natural gas fired water heater and they run a heat loop off the tank for a hydro air handler. The cost for replacement is cheaper and the tenants heating is cheaper were it is natural gas not electric. Not sure if that helps but I would bring the natural gas in.
