Oil furnace to HP in desolate Burns, OR.

[Adlerberts-Protege]

As far as the town of Burns, OR goes, I would put it on the wall of shame, lol. Travelled out there this week to get this job completed.

This oil furnace was real old. Serial number says it was 1994.


Turned out pretty clean. Wasnt as tight as the picture makes it look.


Heat pump is 12" off wall. Another deceiving pic.


Supply static


Return static

Nice installation, I’m a fan of oil to Heatpump retrofits. Great job

Just a tip your fairly close on your esp, I would search for closed registers or dampers or faulted or fouled ducting. Not sure if blower is an ECM model nor filter merv rating.

Cheers

Duct is all rigid and in good shape. I sealed everything up good which is probably why static is elevated. Im happy with .47 considering. My salesman dont do pre-install statics (Im working on that) so I get scared on some of these. That being said they wouldnt have been able to do it anyway as the old motor was seized. I did freak out initially when my original return static was .92, but that was due to the old plugged filter that resided inside the old return, hidden of course. Yanked it out and had an ear to ear grin because I thought I would be doing some time-consuming duct mods.

Looks good to me. Rid of the ductboard and I'm a media filter fan.

Ya. We only use 1" filters in our cheap new construction homes.

That looks great, in Oregon do you not need gas/oil as a backup heat source?

[kdean1]

That looks nice. I consider the job a big improvement o Ed what was there. Good catch finding the other air filter.

Great looking install ! It Must be nerve racking having someone else do the sales work sometimes given the variations of things installers know to look for etc. Good work man.

nice job why was the old unit replaced out my way oil is very common how common are oil units out your way

What's with the open Tee on overflow drain tap? SS1??

Old install, someone resurrected . That is an SS2. And it isn't open, has the little float cap in there breaking the low voltage.

Oil units are probably 5% of systems over here, and fading even further. Due to lowering carbon footprints and energy efficiency rebates, they will soon be all gone over here.

Old install. I do all my own sales now.

Any of the above will work. I set them up per energystar recommendations. Backup heat strips locked out at 35 degrees with outdoor sensor.

Looks good

Are you measuring the return static, before (return side) or after(coil side) the air filter?

I usually get readings on both sides if I can. Depends on the piece of equipment and layout. I mean, we are all experienced enough to know if we are good before the filter, if the after location isn't available.

That's not true. You could have a .01" - .5" or greater pressure drop across a filter depending on ductwork, airflow, etc..

Measuring before the filter would do no good. Proper TESP for a gas furnace would be after the filter(blower side) and before the coil.

An AHU utililizing an after market air filter requires a reading after the filter and before the heat strips for proper TESP

Some of those F##kers, you just cannot get to, that is what I'm saying. Like I said, 99.9% of the time I get there. On this project, it was a filter grill so all good.

My earlier statement can be interpreted somewhat. I think we all know what an undersized filter looks like. Sometimes it just isn't in the cards to make it bigger. Sometimes the customer is cheap. Sometimes, my friend, you move on.

[gravity]

Oh i get it, believe me.

I document all my readings on startup and use a label maker.

I label what speed i checked with clean filter.

Before/after filter PD
TESP
Before/after coil PD

That way in the future, they can put the speed to what i tested with and with a clean filter, check against the PD i labeled and see if there is a issue.
