Description

Overview
Panasonic WhisperComfort Spot Energy Recovery Ventilator (ERV) offers a revolutionary way to provide balanced venilatiuon with a ceiling insert ERV. Affordable and easy to install, WhisperComfort is energy efficient and provides fresh ventilated air while maintaining indoor air quality.

Balanced Ventilation
Tightly built homes and buildings minimize passive air leaks. An exhaust-only fan may create negative pressure. WhisperComfort solves this by supplying air to replace exhausted air, helping to balance air pressure within the home.Panasonic WhisperComfort spot ERV uses two 4 inch ducts - one to exhaust stale air and the other to supply fresh air from outdoors. Its low rate, continuous run ensures chemicals such as volatile organic compounds (VOC's) and other pollutants from cleaning fluids and building materials are vented out and replaced with fresh air.

Spot ERV
WhisperComfort is a ceiling insert sport ERV ideal for a single room. The unit provides a low rate of continuous air exchange. Fresh air is supplied while maintaining balanced air pressure. This is an affordable way to add ERV to a specific room or a new addition. Ideal for home office, game rooms, family rooms.

Whole House ERV
WhisperComfort may also be suitable to meet whole house ventilations requirements under ASHRAE 62.2.

ASHRAE 62.2 2007 Standard
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) set a standard for whole house ventilation, requiring that continuous mechanical ventilation be 7.5 CFM per bedroom (master bedroom x 2) plus 1 CFM per 100 square feet, with sone level not to exceed 1.0 Panasonic WhisperComfort ERV is an affordable, efficient way to meet this ventilation standard.

Works good for mancave

Bought this for my 1500 square foot, 3 car garage that also serves as a mancave with tv and air conditioning. When pulling a car in and out or getting the lawn mower or four wheeler out the stinking exhaust seemed to linger for hours. Not wanting to vent fresh, humid, hot air inside the building I researched this Beauty. People though I was crazy for spending the money but it has been totally worth it! After about 30 min you can hardly tell the lawnmower was in and out of the building. I run it 24 hours a day but turn it off when I turn off the mini split system when I go out of town. I do not use a light switch to control it as of now. I used a wire nut to combine all 3 wires to set the control to high. My building has 1" of spray foam so I consider it pretty air tight. Many "real men" don't mind the smell of a room full of exhaust but if it bothers you, don't hesitate!

I was amazed at how well it worked!

A professional HVAC friend of mine recommended this unit to me for a spray booth that in my basement. Prior to having this I had a fan in the window and the house would fill with lacquer fumes, and my ears would fill with my wife's complaints. I installed the unit, very easily done by an inexperienced person, and tarted it up. I had to get on the ladder again to make sure it was running it was so quiet! Then I left it running after I finished sanding the drywall in a 10x10 room. In less that 10 minutes, the air was completely clear of the dust. Best of all, no more fumes upstairs, and no more complaints from my beloved.

Good product

I use this to add air exchange in my basement office. It appears to do a good job, with incoming air about 55-60 F when my outside air is 35 F. One note, it would be easy to install during new construction, but rather challenging for an existing ceiling with typical attic/insulation above. I had to cut my install hole several inches longer on both ends in order to get at the mounting brackets, while working from below. It just means I need a patch on the ceiling. Supply House did a great job- very fast to ship and arrived in perfect condition. Also best web-site for explaining options and had a competitive price.

I recommend this erv for every home!

Everything about this erv is good and for a reasonable price it completely upgrades the indoor air quality of a smaller apartment/home; my only gripe is that Panasonic should produce a higher volume unit at an affordable price in order to improve air quality in larger apartments/homes!

Super QUIET!!!

I have a 325sf additional dwelling unit (ADU) that apparently DIDN'T need this but I bought it already so I had it installed. Yup, I can feel the difference of the air inside compared to before this was installed (usually muggy and because of construction outside, dusty). It's a bit expensive, but the quiet operation is worth the cost (others I'd compared were WAY noisier!).

Helps with exhaust & wildfire smoke

During horrible wildfire smoke (AQI was 500+), this was a lifesaver when we installed it in our garage. The ERV easily cleared out smoke that crept in through side door entry, quite a bit longer if main garage door was used for entry. That reduced the amount of smoke getting into the house if entering from garage. If you have a family member with asthma, etc. it's a worthwhile investment. We kept it on 24/7.

Improved Air Quality In Home

Installed the unit in the hallway that leads to the bedrooms to improve the air quality in my home. I monitor my air through a separate device and this lowered the VOCs and Co2 in the home consistently. The general smells in the home from cooking and projects dissipate much quicker. Also dumps a fresh air smell into the home all the time. I feel it was definitely worth the work and price to get it installed. Highly recommend the split exhaust vent hood that is an accessory, made the external penetration very easy.

Q: Will this unit suck the heat out of a room if it is left on for a continuous amount of time?

No, it will not.

Yes it will. It is rated at 66% for heating at 30CFM. This is way better than zero, but it will suck heat out of a room.

There obviously would be some heat loss, but this unit is an energy recovering ventilator (ERV) which exchanges the outgoing heat with the incoming cold and vice versa through a capillary system. I believe the heat loss factor with the one we had was 15%, which is not bad considering the job the appliance does with air exchange. We used it in a damp basement in a 200+ year old house in New England, an application that is not recommended by Panasonic, but it worked wonders keeping the cellar air pleasant and the mold spores went out with the stale air.

Q: Hello, My two new ERVs (FV-04VE1) will not operate, although seem to be wired correctly. We are wondering if there is something we are missing. We have the pigtail in the 20/10 CFM space and a dual switch, yellow to "on off" switch, orange to both, blue to "high low." The unit switch is on. Is there any sort of safety mechanism we are overlooking? Thanks for any advice - Panasonic is of no help.

Hello: I had a similar issue with the units I installed. If you look on the main control board, you'll find an "embedded" fuse. These were "bad" in all of the units. Now, whether this was a result of a defective fuse, or less likely, a surge on initial power-up, remains to be determined. The unfortunate part, is the way the fuse is mounted, which is via a soldered connection to the control board. Why not a simple cartridge assembly to hold the fuse? I guess Panasonic saved a few coins on the fuse holder, and could populate the board with robotics. How fix? If you want to maintain your warranty, the board has to be returned to Panasonic - if you are even allowed to remove it from the main assembly. Given your experience with Panasonic (not an isolated one, by-the-way), you may want to return the units for replacement. That was not an option for us. Such a simple thing, but what a complex fix. Good luck.

Is it a basic switch or does it have an integrated timer? When I originally installed my two ERV's I tried to run on/off through a timer. The timer would not work for that application. When I switched to a simple single pole switch they worked.

Any standard dual wall switch should work with this ventilator.
