Damn it's cold!

[Hanau]

So I have the thermostat set at 76 degrees, but the house is at 58 degrees. It's cold in here!

I have 24V going to my thermostat. I get big flame, it's roaring away. The blower is coming on. The heat is not getting to the rest of the house.

Exhaust is clear, vents are open.

The air coming out of the registers is only 60 degrees.

What is the problem?

The heat exchanger is putting out over 500 degrees, the fan is moving the air over the heat exchanger. No hot air is coming out. Somewhere along the way I'm losing all my heat.

None of the limit switches are tripped. Thermostat indicates temp is 58 and it's calling for heat.

sounds like you got a confladulator dohickie valve problem..

[KrayzKajun]

check yur flux capacitor

[landscapesc]

check yur flux capacitor

It should read 1.21 gigawatts...or something like that! I got my windows open here...

[Hanau]

It was working fine this morning. Sometime in the afternoon something happened and the furnace isn't putting heat out.

Got my Fluke meter out and I'm troubleshooting. Electrically it's all fine. There's 7 inches of water column at the valve, gas is passing and being burned. It's not going into lockout.

It should be working fine, but it's not.

It was like that all day here today, now its just a tit bit nipply..

[Hanau]

If I die of hypothermia tonight I'm haunting all you jokers.

Hit it with a bigger hammer...

then light a match...

And Bob, your asking the wrong people, we can move dirt, drive trucks, get 20ton trackhoes stuck and broke then get them out and fixed.

We're not Heating/AC technicians.. ;)

If it is not the flux capacitor, it may be a little tricky to diagnose. Are you getting air out of the registers? Is the blower motor actually pushing air into the ducts?

[Hanau]

Yep, I'm getting a nice blast of 60 degree air. Somewhere between the heat exchanger and the registers it's cooling down. It should be coming out of the ducts at about 130 degrees factoring in heat rise.

Junior, this is basic man knowledge. When you get your man card you'll know stuff like this.

Your ex-wife gave me my man card last night..



Ha!

[Hanau]

Least you could have done was get my balls out of her purse for me Junior.

Looks like I need to get my fat ass in the crawlspace with a thermometer and find out where the heat loss is.

****.

[YellowDogSVC]

sounds like you have paranormal activity. The ghosts are robbing the heat (energy transfer) out of the room so they can manifest, move things, and screw with you. :)

It's also common for the air filters to get plugged very quickly, that's where you should look first.
Start pulling down the ceiling drywall and start looking for holes and ducts that have loose connections.
The biggest loss of warm/cool air sometimes comes from a piece of silver tape that was never wrapped arund a duct line or a junction "Y" that came loose with vibrations and settling.

[zabmasonry]

I'd start by checking your returns and making sure that you have good airflow to the furnace. Then if any of your ductwork is exterior to the insulated envelope of the building check for penetrations.

Other then that. I'd start drilling holes in the duct work (or removing panels if possible) and checking for air flow and temperature. I'm assuming that you operate on a single zone for the entire house, if so, (or really either way) I'd try blocking off all but one of your vents, preferably the vent left open is the closest to the furnace. see if you are getting good airflow and temp there. If nothing else, take disconnect the primary supply plenum and just let it vent directly into the house and get a bit of warmth that way.

[Hanau]

My ductwork is all rotted out. It runs underneath the house. It was sucking in cold outside air which cooled the warm air charge coming off the furnace. Got it patched, but it needs to be replaced.

Oh well, the house was built in 1898, so a few bugs are to be expected. The furnace is 1980's vintage.

Warm air is coming out now. Need a skinny person to run some duct.

You're not a butterball are you Junior? Wanna make a buck?

I'll do dam near anything right now.. *holds himself back from making another exwife joke*

[RockSet N' Grade]

So, the furnace is functioning fine.......its the returns that need to be addressed?

[zabmasonry]

unless you use AC in the summer, get rid of that stupid furnace. either put in hydronic (hot water) which is easy as hell now that we have PEX, or a space heater or two. Hot air is just massively inefficient and prone to problems. or just man up and put in a woodstove. :)

[Hanau]

Yeah, apparently back in the day they didn't use galvanized sheetmetal. It's like swiss cheese down there.

4 rolls of duct tape and I have some warm air moving.

[Hanau]

If I were to swap out the furnace it would be for a diesel fired boiler. I can buy diesel cheaper than natural gas.

[Gravel Rat]

Forced air heat is horrible and that 1980s furnance is probably costing you lots of bucks in natural gas.

One of the guys I worked for bought a pellet stove it is all they use it keeps the house hot.

I do agree hydronic heat is the best but that is alot of money.

A old house has so many leaks the heat loss would be pretty good. Todays houses are so tight they don't breath.

[ProTouch Groundscapes]

furnaces are for sissy's.

get yourself a 8lb maul and start splitting!

we burn through about 4 cords of hardwood(maple&oak) per winter, woodfired stove in the basement runs 24hrs, 88* down there and 70 something upstairs.

last year the furnace kicked on once maybe. we only use gas for the hot water heater now.

gas company thought our meter was broke because it was reading such low usage, so they installed a new meter cause they didnt believe us about the wood stove.

This may be one of the few instances were duct tape is actually used for its intended purpose.

Have you considered geo thermal heating? It saves a lot of energy and once you get it installed its very cost effective. And it works as air conditioning in the summer. Plus I think that you can get a tax break or govt. cost assistance for "going green."

[Hanau]

I might go with a heat pump, I bought six clunkers to cobble together into one useable unit.

Although I really like oil furnaces, they're neat to work on and get tuned just right. Folks around here call me when they're getting rid of their oil furnaces. So I have lots and lots of those sitting around.

Everybody needs a hobby.

hanau here a wood boiler

I've done some work for this company before, geo thermal heating/ cooling is something thats catching on. Although the upfront cost scare most people away.

[1993lx172]

I just finished a paper on sustainable architecture and LEED certifications for one of my architecture classes and while I didn't use geo thermal in the paper I looked into a fair bit and wondered why the heck hasn't this caught on. There's a building just off campus (just across the road on the other side of campus) that is within a few weeks of attaining the highest level of certification possible. A lot of new office buildings, schools, and medical care facilities are going with geo thermal because of the huge savings, but the up front cost is keeping home owners from looking into it. If people would look past the up front cost and look at the long term geo thermal would become more common.

[Hanau]

My shithole house was built in 1898, I ain't sinking geothermal dollars into it.

[jasonnau]

Global cooling man, global cooling.

[Canon Landscaping]

I bet you wish you had a new house instead of that 63k f650.

[Hanau]

Eh, I have a clear line of sight to my ex-wifes house.

[bobcat_ron]

Eat lots and lots of beans and warm yourself. Just stock up in the tidy whities.

Oh and turn off any open flames.

[Gravel Rat]

Bob is probably old enough to have mystery farts you never know what is going to come out till it is too late :laugh:

[ioilyouin]

Beans and coveralls. Warm from within.
