After living in the German-speaking world and becoming accustom to having a Trockenraum, which can be thought as a dedicated room of a building for line-drying laundry indoors backed by a blowing dehumidifier (e.g., Secomat), I would like to replicate this concept in a house in the United States.
I could install a direct dehumidifier in a room. That said, I am curious if I could effectively dehumidify while fulfilling some side-goals (listed below): using a air source heat pump water heater (HPWH). Would a typical HPWH remove humidity satisfactorily for laundry drying in a room?
To help clarify "satisfactorily," note that the Trockenraum concept is not designed to support rapid drying of items but rather provide faster than line drying alone (e.g., fully dry a sopping duvet in three-to-five hours). I plan on having a heat pump laundry tumbler for things that require more rapid drying but can tolerate the beating from the tumbler.
- Decarbonization of the house (HPWH would further this among many other activities)
- Keeping basement dry (it's already very dry — thankfully)
- Supporting accelerated line drying of laundry (particularly large, bulky, and delicate things)
- Cold climate
- Will eventually have solar
- House has ducted AC/heating but the basement is not hooked up into the climate loop (plan on retrofitting the HVAC with ERV and ground source heat pump soon)
