- Lunos e2 ductless HRV system vs. ducted system
The Lunos e2 cost $200 more, but is balanced ventilation, unlike the TwinFresh Comfo The TwinFresh Comfo can operate up to 10 units in series (with only one connection to the AC power), but it does not appear to be designed to pressure balance the house like the Lunos
- Experience with Lunos Fans - GreenBuildingAdvisor
I would consider comparing and contrasting a dedicated and ducted system The Panasonic Intelli-Balance unit is likely in the fight based on the cost of 3-4 Lunos systems including the filtration, sound dampening and installation costs
- Exhaust-only vs. Lunos TrueFresh in a ductless small home
The Lunos e2 runs in one direction for about 70 seconds, then reverses In that 70 seconds even at high speed it doesn't exchange even 1 4 the volume of a closet, and unless there's a pretty good door cut there would be even less exchange between the room and the closet
- Sound Attenuation with Lunos HRV System - GreenBuildingAdvisor
Yes, the Lunos leak some of the critter noice, especially the big pigs but my main concern is the noice level in a bedroom If I could change my setup I would put the bedroom unit in a closet to minimize the noice For comparison the Lunos sound are more distinct and noticable than the Mitsubishi mini split we have in the building
- Automating a Lunos e2 HRV - GreenBuildingAdvisor
The Lunos controller has three programmable modes (I, II, and III) plus the ability to switch to a “summer vent” mode As far as I can tell, this is done via completed circuits over a set of wires either in on off mode (modes I, II, and III) or via a timed action (on off within 3 seconds for summer mode)
- Decentralized ductless ventilation system: Zehnder, TwinFresh, or Lunos . . .
My original review of the Lunos e2 fans appeared here: European Products for Building Tight Homes My review of the Lunos e-go fans appeared here: New Green Building Products — May 2014 Here is a link to a discussion of the TwinFresh Comfo RAI-50-2 manufactured by Vents Anecdotal information: 1
- Lunos e2 vs. TwinFresh Comfo RA1-50-2 - GreenBuildingAdvisor
Looking for thoughts or feedback on the thru-wall HRV's ERV's Specifically the Lunos e2 system vs the TwinFresh Comfo RA1-50-2 What I know about the two systems- They can both work in unison (every 70 seconds or so, they reverse supply and exhaust), during this time the core is regenerating The Luno e2 has a remote wall mount datalogger and control head (an add-on expense $500+) The
- Simple and Effective Mechanical Ventilation
Josh Oduin is in Leavenworth, WA, talking about adding an HRV for balanced ventilation in his new cabin He walks us through his reasoning for choosing the Lunos E 2 HRV over a typical ducted system The Lunos E 2 is a collection of simple components Most of the work is done by a constantly reversing pair of fans and heat exchangers that
