Check out the Lunos E2 HRV – Featured Item

 In Construction, Featured, News, Reviews

We recommend and install the Lunos E2 HRV systems. They are an excellent choice for tiny home where moisture can be a problem.

Operating and wired in groups of 2 or 4, these fans provide continuous ventilation without the need for
ductwork – installed directly in the exterior wall. The regenerative core is charged every 70 seconds,
afterwhich the fan reverses and the incoming air absorbs the stored heat on its way in. Creates a very
quiet heat recovery ventilation system without the need for ducts and balancing, with specific fan efficiency
that is second to none.

The basic unit is a through wall fan, with a ceramic regenerative heat exchanger behind it. Operating and
wired in pairs, these fans provide continuous ventilation without the need for duct-work and are installed directly
in the exterior wall.

The fan’s heat recovery is possible thanks to a ceramic core that is charged in a 70 second cycle. To learn about how LUNOS heat recovery works, watch our short video introduction to the LUNOS system.

For projects with walls thinner than 12″ (eg with 2×6 framing), you may want to go with the Lunos e² Short (6.8″) version, which requires a minimum wall thickness of 7.5″. However, the short version comes with a slightly lower efficency (~85%). Otherwise, furring the tube toward the interior is an option for your project to obtain the maximum (90.6%) efficiency in a shorter (ie 2×6) wall assembly.
