Re: HELP! Runaway Heat
Start with disconnecting the thermostat wires (R and W) at the thermostat itself. Heat shuts off? It's the thermostat. Heat doesn't shut off? Rats. Go to the other end of the thermostat wires and disconnect the wires there. Heat shuts off? It's the wires. Heat doesn't shut off? Something in the controls…
Re: Wireless Outdoor Reset
I've used the tekmar 087 wireless outdoor control many times including on the Us boiler sage control. Works well for me..

Mistakes happen……………. How the contractor deals with them shows their true character.

Re: Can you please critique this boiler setup that was installed in my house two wks ago
It looks like they disconnected and jacked up the original piping, slipped out the old boiler, and slid the new one in its place using a few fittings.

Re: Bit the bullet: bought an HTP UFT-100W on ebay
you can temp the wiring to run it all as one zone with the zone valves manually opened or the circulators paralleled and put the condensate hose in a bucket to get it running so you have heat…

Re: Water hammer - novice question
Thanks for the commentary…
Regarding water level "does not look too high" - I was trying to say it is not above the water level mark on the side of the boiler enclosure when the hammering occurs. During the non-heating cycle the level typically is somewhat below this line by several inches (like the pic above where you are seeing evidence of oil), though several times I have seen it resting above the water level mark. During heating the level fluctuates less than one inch a couple of times or so per second. It doesn't appear to me to be violent fluctuation (i.e., no water splashing in the gauge) but I am a novice at this. My boiler tech told me it is to be expected during heating. This behavior is very similar now as it was with the old piping. Boiler is early '90s, though I can't vouch for how the earlier owners took care of it.
Drain cycle: 2 different boiler techs have told me a weekly drain until the low water switch activates is a good thing, and I have also read it is a good thing. However I have also read about dangers of too much fresh water addition. Reading more carefully I see a probe-type switch mainly needs a yearly cleaning, and this McDonnell switch seems to be just that. So I will have to interrogate the tech about that next time I talk to him.

Re: DHW mode rapid cycling of boiler
There is a huge difference between an 007 and an 0010, but if you already had an 007 doing okay for 20 years, it's probably okay. With that said, short cycling using that tank still indicates a lack of heat transfer which could be a dirty exchanger an air bubble, or several other possibilities.

Is Dave the @The Steam Whisperer still on the site? He is a Chicago area pro.
You might call Able Distributing and get some referrals, they are hydronic smart. Porter Pipe also.

Re: Experience with Aprilaire 800 steam humidifier for radiant floor heating???
We have enjoyed the Aprilaire 800 in our gas forced air system for 10 years. It's the best thing since sliced bread. Even with Tucson's mild winters, it's always very dry in the house.
Our 800 is set to boil the lowest amount of water for the 2200 sq. ft. single level house. Yes..., it uses a decent amount of electricity and I estimate ~$20-30 / month in the winter. The provided comfort is worth every penny. The canister only fully drains if there hasn't been a call for humidity in 72 hours or if the 800 is shut off at the control panel. From time to time, some partial draining does occur. With our use (humidistat set to 35%), the canister lasts 2 seasons. I change it before the system forces a canister change. The old "heavy" canister is full of calcium & magnesium.
The insulated steam line gets hot and only steam is released into the ductwork (a bit above the evaporator coil). It should operate in a similiar fashion with the fan pack. With the fan pack, the 800 will run whenever there is a call for humidity. In our system, I keep the ECM furnace blower running at a low "air circulate" speed 24/7 (for air filtration). The 800 will run as needed without a call for heat. Even if I had the fan set to "auto", the 800 will command the furnace blower to start when there is a call for humidity.
After 8 years, the soleniod controlled drain valve did begin to leak. Over time, the hot draining water eroded the non-replaceable plastic seat. It was a $400 part, but not a difficult job to replace.
I can only say good things about the 800. IMO, it has first class design, engineering, and manufacturing.
