What’s the quietest HPWH configuration for a 900‑sq‑ft condo?
If you’re looking for peace and quiet in your condo, a split-system heat pump water heater is the way to go, if possible. If that’s not an option, grab a quiet hybrid model and tuck it away somewhere it won’t make noise.
The quietest heat pump water heater setup for a 900 square foot condo is a split system, where the compressor is placed outside and the storage tank is inside.
This keeps indoor noise very low. Brands like Sanden or Chiltrix offer efficient and quiet options.
If a split system is not possible, a ducted heat pump water heater with intake and exhaust air routed away from living areas is the next best choice.
Typical all-in-one units range from 45 to 60 dBA, while split systems can be quieter indoors. For condos, choose a sound-isolated space like a closet, and check if exterior installation is allowed by the homeowners association.
