Questions from a Newb...Water Heater and hanging Cabinets

[zapple]

Howdy amigos,

I’m a newbie here with a couple questions.

Just bought a used 24’ Nesting Bird yurt, have it installed on an insulated, raised platform and now getting to some of the interior work.

I’d like to install a propane tankless hot water heater. I’m off grid and anticipate minimal hot water needs in the yurt and am considering a Marey water heater on the smaller side of things.

Typically these units use 4” B-Vent to exhaust out of a space. I understand I need to vent through the sidewall of the yurt so I was going to use a couple 90° elbows to get it out the wall, then back to the vertical position.

1/ What are my options for flashing this B-Vent pipe through the wall of the yurt?

I have a design to build a kitchen along one of the curved walls and am considering building a small section of 2x4 wall to hang the upper cabinets and run an electrical circuit.

2/ If I close this area in with a tile backsplash am I in danger of creating a moldy environment? Should I through some fiberglass in there or change my plan and just hang the cabs on the lattice?

I am off-grid using a small solar electric array in the Pacific Northwest. I am

heating

with wood, but due to use the yurt will go unheated for a few days to weeks at a time. Winter (and Autumn and Spring!) is typically mild and wet — ideal conditions for molds!

I’d appreciate any thoughts, photos, experience y’all can share.


Thanks so much!
