a miracle delivery... need advice

[solRNY]

unit opened, its pretty much insulated thru out:

close up of the exhuast blower, you can also see the drip pan/port for water condenstation,
this is the part where it removes the humidity from the air, i think...

close up of the incoming air port, think there is a thermister to the left,
a damper to recirculate the house warm air so to deforst the heat exchanger when freezes, hmmmmm...

close up of the fresh air blower:

close up in between the two heat exchanger:

 

[solRNY]

i think the kewlest part of this whole unit is this heat exchanger, its quite heavy too:

another useless pic

i plan on installing this HRV asap, at least hang it asap

 

[dreaminmel]

That thing looks like it should do the job for sure.

With the aquascaping, have you considered trying to use acrylic rods to get the shape you're going for? That rock appears dense enough that you may be able to get away with drilling some holes in it where needed.

I'm not sure what it is, but it looks very cool

i actually got lots of those rods with reflectors, the kind you get from lowes, was planning to use them but not not no more as i was told they probably will leech stuff into the water, gonna go for the actual acrylic rod like you mention

I'm not sure what it is, but it looks very cool

i thought it looked kewl too, nice and shiny

Nice pictures of the HRV.
It is the same as mine other than the name they slap on it.
I've had many years of service from mine so I believe you will be happy with it.
Can't help with the installation advice as each installation has it's own characteristics and problems for installation.
Did they give you the straps to fasten it to the ceiling joists?

 

[solRNY]

hi rayjay, thanks for your ongoing advice

yup they supplied some dinky chains and hooks but i will be replacing those with something more stronger. while the unit is operating did you find the vibration to travel up the chain then onto the ceiling joist, where it can creates a noise problem?

 

[rayjay]

Mine never came with chains but instead I was supplied with four heavy duty straps.
They appear to be rubberized reinforced by many bands with perforations to allow for fastening at different levels from the ceiling joists.
I never had any noticible transmission of noise until recently when I undertook to remove the motor and fans assembly to oil the motor and prolong the life.
Metal fan blades were heavily cruded up and corroded and when removing this crap, I have thrown the balance of the unit off a little and now I get some vibration if you stand immediately overhead in the kitchen.
I'll take it apart again (what a PITA it is to do) and clean it better to make the vibrations go away.

 

[rayjay]

I just edited a pic I took of the HRV in 2003 so I could try to highlight the straps. Not the best pic but all I can do.

 

[solRNY]

Thanks for the pic, it helps a lot!
Ours also will be install just beneath the kitchen, going to find some rubberized hardware to use instead, thanks!

Update:
My wife hinted to me to get going on the HRV installation, the house being more humid and hot lately, she said "she wanted some cieling fans installed here and there", I Dont Think So!

So we worked extra hard this weekend to get our HRV installed, here a pic of it hung, spent serveral days picking a location, either or it wasnt ideal:

here a close up of how we hung it, couldnt find any hardware i had in mind to lessen any vibration transmission to the joist but will deal with that later on if its becomes problem:

heres a pic of the vents prepped which will be installed on the outside of the house:

 

[solRNY]

so i drilled a pilot hole from the inside, outlined the 6" hole on the sideing, using a recip saw i attempted to cut from the pilot hole outwards in a circular motion towards the 6" outline, after 30min i concluded this was a total failure doing it this way, becuase not only i was not able to manuver the blade towards the 6" outline accuratly, the blade had cut something that looks like a countersink for a screw head, much frustration... found out that lowes carry a 6" hole saw, so we ended up using that instead,

so here a pic of the nice clean 6" hole:

here is pic of what the 6" hole saw cored out, to my surprize this stuff is THICK no wonder the recip saw did not work well on it,

close up pic of what was cored, not sure what these are called in "building jargon",

 

[solRNY]

so were making progress now!

here is a pic of the both vents installed; exhauts air out and fresh air in, also you can see our FIRST garden-we have much to learn

a view from another angle, yeah-someone needs to mow the lawn

 

[rayjay]

As the siding in the vicinity of the outlet vent tends to "mold up', be sure to keep it clean so it doesn't get unmanageable.

thats interesting, thanks for the tip!

 

[pascal32]

Looking good!

OT, but we're thinking of doing just what you did with you garden - a mulched area with some time of container for planting.

 

[solRNY]

so i just got done screwing together the remaining few duct for the i/o vents, i decided to use hard ducting instead of the flexible ducting as i thought it was more easire to manage/handle but at the scarafic of flow due to using a lot of 90degree, i will have to revist this at a later time to insulate them before the next winter arrives,

here is a picture we took last night in the early morning hours

heres a close up pic showing the connection to the HRV, i used flexible ducting here as the HRV is mount with chains and will move about when bumped,

here what the back side looks like,

we turned it on, and to my suprize, mechanically it was pretty quiet, no vibration at all on the chains

next task is to install the duct to the home vents, i was thinking of unitlizing the exsiting force air duct but learned that it requires the force air fans to be on which adds to the the cost of operating, with the force air fan off it will create different pressures thus unbalanceing the input vs output air of the HRV, so i am going to install it as a stand alone unit so i balance it once and for all,

going to rob 1 of 3 register to the living room for fresh air, and rob 1 ceiling return vent shared with the soon to be new fish room for stale air out, we will see how this goes
