adding an HRV

Weezbo

I have been tinkering with sending a jpeg of the 36 page book for you. i am going to see if i can get it to attach to this and if so it probably needs to be enlarged when you look at it. if it worksok then maybe i can send you the thing to just check through the pages . the solo is right at 100 cfm really close like i say for your application.

Hmmmm...sorta worked.

ever onward...thats close enough for cigars :) you have a tightly sealed home and after crunching numbers you come up within the dial er in range :)

so now if you can read this atachment i can send you the rest of the pages . the solo can be viewed on the Venmar site. it is one extra right piece of equipment for the home remodeler or some one building duplexes or some tidy rambler or ranch style. in a way it is even less expensive than larger appliances in more ways than one. i am excited for you as it really is something that makes a world of difference in the quality of your life. And for whatever the reason i like to see people doing things with thier life that are good for them .

adding an HRV

Ok we have figured out that my house is too humid.Basically saying envelope is to tight. so I am researching HRV's but my house is on a slab single story. Can I place the unit in the attic? Or will freezing be an issue? I have found units with a heater/defroster built in. But how often do the filters need to be maintained?
Otherwise all I could do would be to install it in the laundry room which is on an outside wall. and just run the ductwork visibly.. yuck But I am thinking this unit is going to be a must in order to control my humidity issues.,
and yes I am still going to add the spray foam to my ductwork in the attic. I
I found out a local Indianapolis Insulayion supply house carries it.. I have a friend that is a Retired Union Insulator. He is going to help me with this undertaking..

Ericjeeper there is the solo

from venmar...it is a small hrv for pinner homes where space is a heavy consideration. i do not have a garage so life is not really easy for my van.however what i am getting at is ,do you have a garage?

Ericjeeper

Yes I have an attached garage

It is heated but not conditioned. so There is no existing ductwork out there. But I am seeing what you are saying. I could place the unit in the garage and duct up and over. would a single six inch duct into the first and closer room which is 22x40 be ample?or would I need to run a few longer pickups?House layout is 40x80 the first 25 x40 being the garage, then the great room open 22x40 the rest is two baths and four bedrooms.and laundry.
On a side note the dehumidifier has ran all night.. That dude puts off some heat.. had the great room up to 81 last night..and I have dumped over a gallon from it so far. I tried to place the unit in the laundry room on a shelf.. where I could take advantage of the drain hose.. But there was not enough airflow to the room even with the doors both open and it would cycle off.

What a wonderful Thing.

You Lucky son a gun *~/:) Thats Perfect:) iam fairly certain you are into doing this yourself and doing it to the best of your ability. so, here are some of the Parameters to consider,

1 that the ventilation system you install meets or exceeds current codes and that it meets or exceeds your requirements, we cannot speak of controlled ventilation without some control stradgey and considering the whole house not seperately for a component as some marriages of components require slightly different stradgeies and different temp humidity regions somewhat govern the use of certain components in this widely diversified planet upon which we live.

2 a biggie is where to place the controls especially as you already have things basically finished and want to maintain as tight a seal on the vapor barrier as possible and maintain the integrity of the home from any tipe of "activities" that may undermind the preformance of the system as a whole. so....rather than write you a book on the subject a friend of mine teaches a course on this very subject and has been diligently working on puting together another course for mechanical c,general ,electrical contractors and individuals such as yourself who have an interest in this material. His name is J.D. now J.D. a real quiet gentelman is alot more prolific writer than i,and he uses proper punctuation and paragraph and sentence structure Then too , he is into compiling all kinds of cases studies and really "Up" on this specific aspect of the trade. i think he has written a revised edition to the >Alaskan Craftsman Home Program<.

this loose leaf book they have is fairly inexpensive and is sold in many lumber yards here to encourage carpenters general contractors and skilled homeowners a means to refamiliarize themselves to various aspects of building in this region which is important to ensure the information is available economically and used in designe considerations. There is another outfit called Wisdom and Associates who after the first of the year are having an on line class in Hrv's with a study class and written practise tests and CEU's sorry Continuing Educational Units for upgrades to ones Liscence. i belive there will be or already is a certification class .this certification we have draws people from many states and countries.

it isnt a biggie buh i have an appointment or two today....so if you see an e-mail tomorrow, it will be for an outline on our code "guideline " . it adresses co and a host of considerations. one thing though after the read you should find that things are relatively straight forward.

then too i will be able to hang with the conversation . do you have any info as to the cfm's required per room for example. then i can say yes why yes i do *~/:) and depending on the method you chose we can determine it using this formula...like that. and it is easy for you.
