I don't believe the OP is a homeowner, but a fellow tradesman looking for advice.The day you stop learning something is the day it's time to find a new career.

Please use correct grammar. (And only hit the "submit post" button once). I noticed that YOU didn't answer my question, only criticised as usual.

Multilpe Boilers

On a multiple boiler install, with pumps on each boiler, does it need to be piped in reverse return?


Don't Know

@ December 20, 2013 1:15 PM in Circulator pump location

I don't know if it makes a difference with individual boiler pumps, but with multiple boilers and a single pump, I was taught to pipe in reverse return, so that's how I pipe all multiple boiler installations. That said, do it just like Hot Rod's diagram, but maybe in reverse return? (don't listen to rjb, he only seems to be able to offer criticism, not help).


One other thing

@ December 18, 2013 3:59 PM in Weil Mclain ultra gas-fired water boiler 399

This is not related to the outdoor sensor issue. I don't know about your area, but here in Virginia it has been colder than in many previous years for the months of November and December. This will obviously affect your comparisons to previous years.


Closley Spaced Tees

@ December 18, 2013 3:33 PM in Insufficient heat from system

I cant tell from the photos but if you have a valve in between the closley space tees, if so shut it and see if the flow goes through your baseboard loop.


Tub and Faucet

@ December 18, 2013 2:42 PM in Hot water baseboard heating

I know this is not the main problem, but could you post a couple of pictures of the tub and the tub and shower valve and shower head?


@ December 18, 2013 12:10 PM in Math quiz at end of first post after login...

If I am in the middle of a post and want to scroll down and enlarge one of the photos, when I enlarge it, my post gets deleted. I have learned to work around it by opening another window and looking at the photo there. Might just be my computer. But just like everything in this industry, where there's a will there's a way. (it just may take a while to figure it out) :)
I as well have never had a problem with the math question.


Clocking Meter

@ December 17, 2013 2:47 PM in Hot water baseboard heating

Someone needs to clock the gas meter to see if the boiler is actualy putting out its maximum  output at high fire.


@ December 14, 2013 2:49 PM in Hey Dan and my fellow wetheads

On that note where are you  located? I seem to recall that you are in Virginia? I am in Winchester.


@ December 14, 2013 1:19 PM in Hot water baseboard heating

An HVAC company cannot do a heat loss on their own! Did you get a copy of their findings on room size, insulation, etc.? If you can post that info here we can verify (approximately) the heat loss. Just to keep them honest.
Please let us know.

Check valve

@ December 13, 2013 1:32 PM in Knocking... Sometimes...

It sounds like the check valve is chattering. It is a swing check and should be a spring check. You are also missing a spring check on the boiler return line. Call you installer and have him fix those check valves and you should be okay.

Expansion Tank

@ December 7, 2013 4:44 PM in radiant service in Minneapolis

It is possible that your expansion tank bladder may have blown out releasing air into the system. Try removing the cap and putting a tire pressure gauge on it. If it reads zero or water comes out of it, you need a new tank (not expensive or difficult to replace). give it a shot and let us know.

Press fittings

@ December 7, 2013 4:29 PM in Copper Press Fittings

Is there any way to disassemble a press fitting without cutting and coupling?


@ December 7, 2013 4:24 PM in Rotation Indicators

If you cannot afford to give a customer a five dollar piece of ADVERTISING on a multi-thousand dollar boiler installation then you need to charge more! I think it would be great as a giveaway, and while explaining the system to the customer you can show them how to use it. People in this day and age love gadgets.

Radiant Heating Info

@ December 7, 2013 1:51 PM in radiant service in Minneapolis

Go to the "Shop" tab on this site and purchase the book "Hydronic Radiant Heating". You will find it in the hot water heating book section. It is written for the layman and is a fun read. It will aid you immensely in understanding your system. (and help keep this site going) :)

How did you end up with a beta test system in your home?
What were they testing?
Who owned the house when the system was installed?


@ November 22, 2013 1:35 PM in Help! Unusual system design problem

I was looking at the instructions for the UPS Series 200.


@ November 21, 2013 4:23 PM in Help! Unusual system design problem

I just checked the literature and these pumps should be mounted with the motor upwards.


Primary Secondary

@ November 21, 2013 3:16 PM in How Does this Install Look?

I don't know the flow rates of the zones but I would not feel comfortable not having primary secondary piping on that system. The installer did obviously take pride in his or her workmanship.


Taco FuelMizer

@ November 21, 2013 11:08 AM in Problem heating second level

You may have an improperly set up FuelMizer. The FuelMizer is designed to give your boiler outdoor reset control. This means that when it is warmer outside it supplies cooler water to your baseboards and when it colder it supplies hotter water. These units take some trial and error adjustments to get the water temps set up correctly. It may simply be an adjustment issue. Go to this link and download the instructions if you don't have them. Let us know if this helps.

Nice Install

@ November 17, 2013 2:52 PM in Twin Aerco boilers installed this week. Really like these boilers.

Very nice install especially for such a tight space. My only question is regarding the size of the gas piping, It looks awfully small for 300K plus BTU's? What kind of units were there before? It sounds like this is a residence, how big is it?


@ November 17, 2013 2:02 PM in monoflo

With 80' of pex and no under-slab insulation your fighting a losing battle. Without supplemental heat you WILL lose.
