Depending on how hot the tank is set for and who might be using the hot water, a mixing valve might be appropriate.

I've got my heater set at 140 and keep telling myself to add the mixing valve....

Pete - a couple comments:

I think you've described things fairly well. Your comment about drawing pictures is a common desire. You can post pictures (or drawings saved as pictures) in this forum...

18 gauge is common for thermostat wire - 2 conductor is minimum required for heat only - you'll need at least 4 conductor for heat and A/C

I've seen power to circulators handled with either...

Any single pole switch rated for at least 24 VAC should be fine. I'd probably just use a simple light switch.

That's a good point Jad. The thermometer well has a ledge in it that can "hang up" the sensor. Since the ledge is in a ways, if the sensor bulb is short enough then the installer might not notice...

Your picture labels are right on the mark.

If the aquastat is calling for heat the circulator for the indirect will be running. The circulators are pretty quiet compared to the noise of a boiler...

I sure don't see a zone valve on the indirect piping. The only thing that might be a flow control is the brass fitting between the indirect and the circulator. Is that just a check valve? I can't...

Pictures help. An existing indirect tank was replaced with a SuperStor.

A few more close up pictures of the entire supply and return lines between the boiler and SuperStor would clarify the...

Pictures, post pictures



Yup - the aquastat should control flow to hit the target temperature. If it doesn't then something is wrong. This is kind of important and it could be a safety issue....

The SuperStor is an indirect water heater. It's basically a big tank with a heat exchanger in it. It looks similar to a stand alone water heater but it doesn't have a gas or electric line attached to...

Was the Superstor zone added with a control valve or just a circulator?

Assuming the thermostat is working correctly, I'm guessing that "ghost flow" may be a problem.

I'd suggest just shimming it on the existing pad rather than going to a lot of trouble trying to re-level the ground. The concept is that the existing pad has settled all it's going to so shimming to...

When I was taught to sweat we cut our joints lengthwise and then tore the halves apart to examine the solder coverage. Solder on the outside does not necessarily mean solder on the inside. Take some...

Ask the plumber when you call him. He's been on location so he should be able to give a fairly good estimate. Maybe also call around a bit to check pricing. Some of the dedicated "roto-rooter" types...

Hmmm, unclog the stack or add a component to the system?

My answer would be to unclog the stack.

Sometimes adding a component to replace the function of a failed component is a good idea. In...

Naw, it couldn't be that. It had to be the 'slagit that plugs into the gozonda. Those things are always going down.:)

My old system had Honeywell V8043F and I changed one powerhead. No water leaked while changing the powerhead.

It should be fairly easy to tell if the powerhead failed or if there is another...

No. Just check the pressure with all fixtures shut off and ahead of any PRV.

I get about 1.2 sq in for 1.25 in diameter pipe. Am I having a bad day or is Gary?

At least we agree on the area of 1 in pipe.

In general, no. A damper such as you describe would be a dangerous obstruction.

Some appliances have powered dampers to prevent backflow. Those appliances also have controls setup to prevent...

Have you checked the B&G website?

Looks like they've got a page on seal replacement. I always considered the seal part of the pump and I hope...

First off, I am not a professional plumber, pipefitter, or electrician. Now that is out of the way, the blower will be controlled by a relay. That relay happens to be stuck in the closed position....

You've got to keep the boiler hot in order for the coil to deliver hot water. Does that tell you that the aquastat controls the boiler and the thermostats control the circulators?

I don't know a...

Oh good ***, grumble. This is a DIY forum. Lots of folks mess around with molten lead and alloys of molten lead. Ammo reloaders who cast their own bullets do it all the time. Anybody that handles...

Lasik is soooo yesterday. Go for implantable contacts!

Ok, I'm being a bit facetious. Consider the risks and use the appropriate technology. You've only got two eyes and probably depend on 'em...
