MIDEA Ducted Minisplit / Heat-Pump Water Heater Location
I’m getting closer to the HVAC decisions. A Small Planet Supply sales person suggested a Midea 18k BTU ducted heat pump for my 868 square foot (but 10,000 cubic feet bc. high ceilings) house in the mild western side of Oregon, zone 4C. Several other HVAC installers quoted me for 24k systems with two interior heads, but I like the idea of putting a ducted unit in a central closet and then pushing air to the two main regions of the house.
a) The MIDEA (Advantage 18K Ducted) is a lot more affordable than a comparable Mitsubishi Unit (about half the price, installed). Is the Midea a reliable product? I have a question out to the installer about the # years warranty. What experiences have you had?
b) I had planned for a heat pump water heater to go into that same centrally located closet. To address the room size requirements of the 50 gal Rheem I was thinking of, I planned to leave the closet door off, for air flow (closet volume is about 240 cu. ft.). However I am learning that it is also not recommended that a heat pump water heater go inside a conditioned space, as the energy savings for water heating could be offset by increased need for heating.
My primary heat source will be a woodstove, located adjacent to the centrally located closet. However I don’t know as I age whether I will get lazy about keeping a fire going!
The house will primarily be for me, and my hot water usage will be a nightly shower at 2.5 gpmx15 minutes =37.5 gallons at most, plus dishwashing/sink use throughout the day. In addition to the concern about cold air being produced by the water heater, I am concerned about noise. The closet containing the unit will be adjacent to my bedroom. I considered putting the unit on vacation mode after my evening shower, and then turning it on in the morning when it would be less irritating. I read some posts here and people were saying that the Rheem 50 gallon was quiet.
*Since I’m on a well: ground water temp looks to be ~52 degrees here.
Will leaving the door off the closet address the air circulation needs? At my (somewhat low) level of hw water use, and with the concerns about cooling the conditioned/heated air, would I be better off simply getting an electric water heater?
I had been pretty sold on the heat pump hot water heater until I came across these concerns. I’m surprised that that HVAC installer who came out didn’t mention anything when I said I wanted it in an interior closet.
I look forward to hearing from you, and thanks in advance!
