Couldn't Agree More

@ March 22, 2014 11:00 AM in Pipefitters shoulder

JohnNY, that's whatI did, very light weights, starting at about 9 o'clock, which is toward my side, and lifting over my head, rotate your arm to 10 o'clock, lift over your head, etc. etc. until you can't get anymore, about 2 o'clock, then I would do small rotations with the weight up high directly over my head, gradually making bigger circles, until the weights were about head level, it took a surprisingly short amount of time to fix my shoulder, it lasted for a couple of years, it's coming back and I just started doing them again. Don't let em cut you unless you have too.

Thanks, Bob Gagnon

I agree with Gordy

@ March 21, 2014 9:19 PM in Warmboard on slab versus PEX in slab

Close pipe spacing and good insulation will make the slab heat up in a couple of hours, instead of a couple of days.

Thanks, Bob Gagnon

Have you tried

@ March 21, 2014 9:11 PM in Pipefitters shoulder

Ice and exercise?

Thanks, Bob Gagnon

Bill, Just Google

@ March 18, 2014 11:50 AM in 56 year old copper pipe radiant floor heat. Leaks.

Leak detection, Long Island, Ny and a bunch of contractors come up, you should fix it before you add too much fresh, make up water to the system which will cause more leaks.

Thanks, Bob Gagnon

Couldn't You

@ March 14, 2014 6:47 PM in Plumbing Forum?

Shut off the water main, open a faucet down stairs on the water heater and try and blast out those galvanized mains by attaching a hose to your upstairs faucet? I've heard of guys doing this.

Thanks, Bob Gagnon


@ March 12, 2014 8:21 PM in Legionnaire's found in heating system

I saw a TV show that said copper pipes will kill legionnaires, and they said if you have plastic pipes to make sure you have a copper shower arm and shower head. Wikipedia says that cold water would have to be above 78 degrees to contain Legionnaires, is your cold water that warm?
Thanks, Bob Gagnon

You Could Try

@ March 11, 2014 8:55 PM in Mono Flow Issues

Burping air out at the circulator flange, by loosening the bolts until air or water comes out, when the boiler is cold of course. I had a taco 007 once that was cast metal across the pump opening, I couldn't get that on to bleed, and spent a lot of time figuring out that one.

Thanks, Bob Gagnon

Shut The Boiler Off

@ March 10, 2014 10:36 PM in General Steam Heat optimization

With the electric switch, then overfill the boiler. a little ways past the top of the sight glass, check back in an hour or so, and if you have water at the base, it's leaking. Boilers often leak at the waterline. The bills seem very high, I would guess that you either have a leak of an extremely bad install, it is a good idea to change over to gas.

Thanks, Bob Gagnon

The Daily Mail

@ March 10, 2014 10:24 PM in Legionnaire's found in heating system

Reports that 20% of Legionnaires cases are caused by using water in your windsheild washer bottle, instead of windsheild washer solution, which inhibits bacterial growth.

I Like Staple Up Better

@ March 8, 2014 3:11 PM in Recently Completed Radiant Job

With no plates, I get more heat when using multiple runs, I run a max temperature of 135 degrees for the staple up, but with the boiler on outdoor reset, it gets cooler than that on warmer days. Staple up is easier for the other mechanical trades to get by, and is less likely to get drilled or nailed. I have never needed supplemental heat when using staple up with multiple runs. The pex is Wirsbo/ Uponor and the manifolds are too, I used 3/8" pex for the staple up. The holes I used varied from 1 1/2' to 2 1/2" depending on how many runs I had to get through the holes.

Thanks, Bob Gagnon

I Always Use

@ March 8, 2014 3:02 PM in Recently Completed Radiant Job

Utica Boilers, I have had very few problems using their cast iron boilers over the years, and I am really impressed with Utica's High Efficiency Boilers. This is a Utica SSC series boiler. The owner of this house has a house right next store, that he built about thirty years ago and we have a Utica Cast Iron Boiler in there, that house is only about 2000 sq ft, but the gas bill from that house from last month is $450. We figure the new house is using one-fourth the energy, when comparing house sizes. The houses are insulated similarly, except now we have the stretch code in Lowell and every crack and seam must be caulked on the building's envelope. The new house feels like a foam insulated house, by utilizing this low cost method to reduce air infiltration, I used to think you needed foam, now I'm not sure. I credit the High Efficiency Utica Boiler, with the Radiant heating and really tight construction, as the three biggest reasons that the bills here are so low.

Thanks, Bob Gagnon

Robert, I have been working for this family for decades so they give me what I want, enough room for multiple zone boiler layout and plenty of insulation, that's half the battle sometimes.

Thanks, Bob Gagnon

I would

@ March 7, 2014 12:56 PM in Heat loss through rim joist

Move the tubing also. I seal the bay ends with silicon then I put 1" or 2" of reflective foam board, and then have the insulation contractor install 6" fiberglass blockers, when he is insulating the floor. There is a huge heat loss through the rim joist, as the Radiant heated bay is the hottest part of the house. Not sure where you live but here in Northern Massachusetts it seems like it is near zero for much of this winter.

Recently Completed Radiant Job

@ March 7, 2014 12:38 PM in Recently Completed Radiant Job

Here are some pictures of a large Radiant job I completed this fall. The customer just called, and he was extremely happy to report that his gas bill for a 3700 sq ft house was only $200 for last month, up here in northern Massachusetts, near the New Hampshire border, no one is in the house yet, and there are no appliances or curtains, yet the gas bills are ridiculously low, with the thermostat set at 68 degrees 24/7 and with the extremely cold weather we have had this year. The house has 6" walls with fiberglass and no foam except for the slab/ lower level and the ends of the bays where I have staple up. The slab mixing valve is set to 110 degrees and on initial startup the customer called to happily report that the slab, and room, had come up to temp in only a few hours. When I was working there I turned the thermostat down to 65 degrees overnight, and back up to 75 in the morning and it took 2 hours and 15 minutes for the room to hit 75 when it was ten degrees outside, I have 4", 8", and 12" spacing in this well insulated slab. The customer will use setback here, on the slab and staple up, once he moves in. Matching up a High Efficiency Boiler, Radiant with close pipe spacing and a well insulated house is a win-win situation.

@ March 5, 2014 12:06 PM in Help!! staple-up insulation foil myth

Is right about the like button, if we saw a reply had many likes we would know that it is likely the correct answer.

Thanks, Bob Gagnon


@ February 22, 2014 1:45 AM in Scott's radiant heating project

Most people won't consider it because they don't know the warrantee only extends to the original purchaser. I have gained a lot of customer appreciation when they call and are selling their house, and I forgo the boiler installation because the warrantee will end with the sale, being honest will get you customers for life. Give the buyers all the information and let them make the decision, some may not want to deal with a boiler installation, others will want a full guarantee.

Thanks, Bob Gagnon

Don't Replace The Boiler

@ February 21, 2014 10:47 PM in Scott's radiant heating project

The warrantee goes to the original purchaser, so in effect the new owners would be buying a new boiler with no guarantee, give them some money off the selling price, they will appreciate your honesty.

THanks, Bob Gagnon

I Concur

@ February 21, 2014 10:40 PM in Help!! staple-up insulation foil myth

WIth my colleagues, I have done it both ways and foil doesn't seem to make a difference. You should be able to get this info written down in Uponor's Literature.

Thanks, Bob Gagnon

You Should Use

@ February 21, 2014 6:45 PM in taking a hot water zone off of a steam boiler

A Stainless Steel or Bronze circulator, not a regular 007.

Thanks, Bob Gagnon

Get A Price

@ February 21, 2014 6:38 PM in Can't Get Baby's Room Warm

To separate the piping and have a separate zone for the child's room. This may be cheaper than getting CI baseboard throughout, but it may not, get a price for both. A separate zone would be best because you could keep the two zones as warm, or cool, as you like. A lot of adults like to sleep in a much cooler room than they would have their baby sleep in, separate zones would allow this. Most important, when they remodeled they didn't make a small room out of the boiler room, did they? This is a common problem; if air for combustion is not allowed into the boiler room, carbon monoxide deaths could occur. Make sure you have multiple carbon monoxide detectors, and have your plumber take a look at the boiler room when he is giving you a price on the CI baseboard/ separate zone installation.

Thanks, Bob Gagnon

Some Hot Air Systems

@ February 16, 2014 10:29 PM in Wood heat transfer

Have a separate switch on the thermostat for fan only, this would help move the air from your warmer room to your cooler rooms, it works ok without changing any of your ductwork, maybe your electrician could wire your thermostat if's not wired like that already.

Thanks, Bob Gagnon

@ February 15, 2014 10:28 PM in Dodge promaster van

I've been really happy with my two year old Ford Box Truck,, no repairs, tons of room to stand up and great in the snow with four wheel drive, we've had nothing but snow up here this winter.
