Bonafide, that link isn't working for me...what is is talking about?

Actually spoke with some Building Science people and they are a little concerned about foaming the roof since I already have a...

well the results are in and the energy audit showed there was plenty of insulation in the attic but there was some leakage in the ductwork noticed during the blower door test....

I guess the poor...

thanks guys...i'll stick with tried and true - no HV

I'm going to be building a new summer home on the shore in New England and was thinking of going with a high velocity heating/cooling system. Is there a lot of experience out there with them to say...

No cans, etc...ceiling upstairs is sealed with blown in foam. BUT Icynene now says that it needs a vapor retarder and my builder just primed the ceilings (cheapskate and I didn't notice the...

Sorry for taking a while to get back to you guys...no big snow till now and I was out of town too. We got almost a foot of snow in the Boston area and without running the fan last night the attic...

well got the cellulose...still a bit too warm. Even with a gable fan running all night it only got down to 6 degrees warmer than the outside temp when I got up at 6am today. I guess the R6 (or 8 I...

If you are in NE, who did your blown in cellulose? Anyone near Boston? Not a lot of contractors use cellulose it seems.

I don't remember how tight the house was but the guys from Building Science who know it all tested it with their seal of approval. The ducts haven't been tested since being replaced though. I will...

they do have styrofoam baffles but foam has seeped in and blocked quite a few, mostly those over the kneewall since it was such a long run.

sounds like the same song and dance - "you only needed x inches" not the 9 inches to achieve R30 code...Icynene is definitely >1.7/inch though...I guess the contractor didn't use Icynene? Was there...

Bathroom vents being used don't seem to affect the humidity up there so I think they are tight. We had a duct blaster done on the original ductwork that was here - but we replaced it and they...

we actually had a blower door test on the house at one point and it was tight by building science standards, so I don't think there is a void that was missed...i don't get any negative pressure...

Hi guys, while not quite HVAC - it is heat and ventilation related...

I've been in this new home now for going on 3 winters and so far it hasn't been a big problem but we got hit with ice dams...

well enough of you put some fear in me I turned off the boiler after we all showered today and don't need anymore hot water....thanks for the advice

Talked to the tech again locally and he said the same thing, at 40 the pressure relief valve would have blown by now...thinks the guage may be faulty...nothing on floor to worry about at least. ...

pressue is 40

I'll go check the pressure and Fyi its only a 2 year old boiler.

I called my heating company today and they said it could wait till the week...not an emergency the tech thought. It does appear that the mositure on the floor eminates from under where a copper pipe...

Can an oil boiler leak water? I noticed water right around the base of the cinder block the boiler sits on...it looks like there is some sort of copper pipe coming out of the boiler where something...

thanks so much mark...i'll get that jumpered! And I've been meaning to install a better stat so I might as well do that too. Good thing I asked as that's not enough air flow to let steam properly...

Aprilaire suggested the return as there was no area in the supply duct that would allow for a straight run of 36" before elbows, dampers, etc. to allow for proper dispersion. Unless I put it on 1/3...

50% would be OK I would think. If i'm 3 tons at 350CFM that's 1050 CFM. Split into 2 returns at 50% I guess that means its getting 262 CFM so close to the 300 they want. Guess if I turn dips up to...

Its a TWE037. Not sure what we have outside now but for heat season it doesn't matter as we use an aquacoil hydroair for heating. Its set for 350CFM now on the dips but that is what it blows at...

I'm not home right now but the smaller 2.5 ton unit is a TWE031 VS unit - the one in question is the 3 ton version of this model. thanks...
