Plumbing / MOVED: Overheating issue/question

General DIY remodeling without Hydronics / AC2 treated lumber
« on: April 07, 2020, 11:15:50 AM »
Have a new sign to make, whatís the recommended primer and paint for the new AC2 lumber?

I went to Menards awhile back as we have a new mega one, even treated is kept inside, figured it would be dryer than the stuff Iíve seen water running off when they bring it into the store at Lowes. Moisture meter says itís under 15% but water still beads so not sure its dry enough yet to paint.

So opened up under the stairwell going to the second story and found something interesting. They tore the lathe and plaster off the one wall and left the other. What was left they wrote a poem on, signed their names and dated it. House was built 1857, poem was wrote 1883. Plan is to fasten a piece of plexiglass over it and leave it. Have zero clues as to where the original stairwell was located.

Also the exposed section of wall had zero insulation in it, it was tried to use blow in cellulose above it but just fell down the wall cavity and left a foot of it under the stairs. To top it all off when central heat was installed a 10Ē cold air return was ran a few foot off the furnace then right up under the stairs, a few registers were placed in the kick boards near the bottom to pull cold air from the upstairs down, only issue was near the top of the stairs a void was left that went right under the flat roof, so for the last 100 years(?) the cold air return has been literally pulling air from outside, central AC has also been pulling hot air from under the roof. Even after cutting a door opening in when the furnace kicked on the cobwebs would move where the air was coming in from the flat roof. Immediately noticed wood consumption went down after boxing in the registers in the stairs, connecting directly to the cold air return and closing off and insulating the void at the flat roof.

DIY remodeling with Hydronics / Copper tubing for wall heat?
« on: January 25, 2020, 12:26:21 PM »
Years ago we remodeled our bedroom, if it had been recently I probably would have used Ultra fin, would have been tricky as it would have had to be installed from the top before the subfloor. Its not even a crawl space under that part of the house, I honestly think that room used to be a porch that was enclosed. Or maybe I would have done radiant walls then, no duct to that room at all. Fieldstone walls so donít even want to tackle getting a duct thru em.

Going to remodel the office next, it shares a wall with our bedroom, Iím seriously thinking of taking two rolls of 1/2í or 5/8Ē copper and placing fifty foot in a stud bay then doing another for a total of 100í. Place a small register at the bottom and another at the top and see what happens. New windows and siding and we filled any voids when we tore the lathe and plaster down. It doesnít do bad most of the time, although on colder nights it does get chilly about 4am, a small window unit takes care of AC in the summer.

I figure why not, I already have several other zones set up in the house and have a spot left in the zone controller, just need another zone valve and other miscellaneous supplies.

Advanced Electronics / Control By Web
« on: March 20, 2019, 10:16:36 PM »
Played with the Raspberry Piís for a bit, but Iíve found the Control By Web stuff while spendy to work VERY well. Havenít had to reboot one yet and their Mobile App also works very well.

SO far have a X-300 in the shop monitoring temps and have wrote a script to control the pump between the waste oil boiler (storage of 450 gallons) and the G200. I had a Tekmar differential controller doing that and it took a dump, the X-300 cost less than the Tekmar and can do so much more.

It has three built in SPDT relays, one is controlling the pump on the storage, the second I can turn on all the heat in the shop remotely and the third Iím going to write another scrip or maybe use the built in logic functions to control the ceiling fans in the shop.

I ran a single run of of ethernet cable for all the sensors and SSR in the shop. You must use a SSR, a standard relay when it shuts off the collapsing magnetic field in the coil will create a voltage spike then the X-300 will drop sensors. Sometimes it picks em back up and sometimes needed restarted. Since SSRís (solid state relays) have no coils, no voltage spike when they shut off. I simply bought the ones with a 3-32VDC input and used the same power supply thats powering the X-300 to power the SSRís then simply wired them in to bypass each thermostat in the shop. Press a button in the app and all the heaters start, when it hits 60F they shut off, drops to 59 they restart.

Also running a X-400 with a X13 companion module to read a stack thermocouple and a reaction chamber thermocouple. Have a X-410 in the basement, can start the snow melt remotely and if the temps drop low enough on the supply from the G200 it kicks a relay in to start the furnace secondary loop pump so the furnace can back feed heat to the boiler.

Plumbing / Kick space heaters
« on: July 27, 2018, 02:14:17 PM »
Anybody have a good brand of kick space heater?

I believe Supplyhouse has changed brands, reviews for the most part with very little complaints of noise unlike the previous brand.

This will be installed under a book case in a single stall garage converted to a family room.

All Iíve seen so far are 1/2Ē connections so figured to grab the return line from the furnace HX and use a mono flo T to divert part of the return to it.

Equipment / Clamp thermocouple
« on: January 04, 2018, 02:02:57 PM »
Was browsing on Amazon the other day and came across this: https://www.amazon.com/gp/product/B06XCG1NYC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

If you already have an electric meter with the temp option this is a cheap way to get pretty accurate readings of pipe, copper, or pex.

Advanced Electronics / Wireless monitoring
« on: January 01, 2018, 08:49:04 AM »
This was brought up on a Facebook group, appears it would work very well for OWB applications.

Iíve been looking close at the ones that can have a thermocouple connected to it, place it at the breach of the G200 and monitor stack temps wirelessly.


WoodMaster / Stuck fan on 434
« on: December 31, 2017, 06:42:37 AM »
Got a call last night after midnight, guy that I installed a used 434 said the water temp was dropping but it was stuffed full of wood.

Not that far a drive, 15-20 minutes tops, so I grabbed a few tools and headed that way.

Got the cover off and sure enough flapper was open but motor wasnít spinning. Stuck my finger in and rocked it back and forth then a couple of good flips got it going, shut it off and tried to get some WD40 under the squirrel cage and to the motor shaft. Got some to it as could hear a change in pitch.

Theory is creosote got around the shaft then with the -3 temp and -15 windchill it set up tight, door was facing right into the wind as well.

Any secrets on these to keep that from happening again? Iím tempted to drill a few small holes right at the fan hub so its easier to get some lube on the shaft.

Plumbing / Nibco pex
« on: December 11, 2017, 09:04:24 AM »
So looking to just start taking sticks of pex to jobs instead of fighting coils, only thing I can find locally is Nibco, I know awhile back there was a lawsuit against em as they supposedly had a premature failure of the pipe at the joints, anybody know of what came of this and has the issue been resolved.

Plumbing / 1 1/4Ē pex to 1Ē mpt
« on: November 21, 2017, 02:31:33 PM »
This has come up before (I think) is such a thing as a 1 1/4Ē pex to 1Ē mpt adapter available? If so from whom?
