I Would

@ July 15, 2014 10:16 AM in How Long

I would hook up a hose, run water through it, pressure test it, then with the water running measure the water temp going to lake, and temp coming up from lake. I have 56 degree water here that I use for cooling, but I have heard of a similar cooling system, maybe a hundred years old that uses water from our historic canals to cool an old mill, the temps must be 70 during late summer, but a plumber told me that it still worked pretty good in the summer.

In Massachusetts

@ July 14, 2014 5:18 PM in Mod/con poll. Installers only.

It's easy, the chimney liner and rebate for mod con , makes 1 the correct choice. Add more baseboard to get your operating temps lower, and tighten the buildings envelope for optimal energy savings. I have been in business for 35 years, installing mod cons for eight years.

Thanks, Bob Gagnon

A drum trap with the clean out plug on top, so you can monitor and replace marble chips.

Close to NH Rob G., I use about ten gallons a minute to cool my house, and yes the lawn is greener than ever. I water and run my Radiant Cooling only 2 or 3 weeks a year, and that's the only time I water. But I water deep, for hours at a time, encouraging deep root growth and the trees, gardens, and lawn seem to love it. We have a high water table here with unlimited water, but you could use a closed loop system, circulating water through a system of pipes underneath the ground, that would pick up the cooler temps, without pumping any actual water. It costs less in electricity to circulate water through a closed system, compared to pumping, like I do, but you don't get the water. I built my house in the late 80', with 2X4 construction and no air sealing, so you can expect a newer, better insulated home to perform even better.

Radiant Cooling

@ July 12, 2014 10:48 AM in Radiant cooling

Fishing the last couple of days, no time to respond, we caught an 8' shark yesterday. Wayne, the fan coil is ugly but I put mine in a closet and just have a finished grate on the sheetrock wall you can see, and the water I pump out of the ground is 56 degrees, to give you something to go by on the Lake Project. My well is only a point driven well, I don't filter the water, but I run it through a heat exchanger to protect my heating system from the corrosion of all the ground water pumping through it. After the ground water cools my house, the water goes out to a 12 zone sprinkler system. Ice Sailor, I have a drip pan under the fan coil, and this removes enough humidity to lower the dew-point in my house, enough so the radiant floors, walls, and ceilings don't sweat.I tried cooling just my floor radiant first and they did sweat without a fan coil to remove humidity.  This is no big deal where I live because we only use our cooing a couple of weeks a year, but further south where cooling costs are much higher, it could be a really big deal.

Thanks, Bob Gagnon

That Would Work Wayne

@ July 10, 2014 6:40 AM in Radiant cooling

My ceilings and walls are heated/cooled with radiant, less thermal resistance than a wood floor, I built a large fan coil unit, out of 100' of baseboard element, that provides lots of cooling and dehumidification. This would give you the biggest bang for your buck. My bedroom is 68 degrees right now with just this fan coil running.

Thanks, Bob Gagnon

You can' read it

@ July 9, 2014 3:28 PM in Watts

Easily. But it says "cut no dashed lines for display" it should read "cut ON dashed lines for display"

Needs a proofreader.

Radiant Cooling

@ July 9, 2014 11:56 AM in Radiant cooling

I'm lounging in 73 degree radiant cooling comfort right now. The comfort is the equivalent of radiant heating. I remove humidity much in the same way conventional ac does, with a large fan coil unit, but my fan coil and radiant surfaces are chilled only using well water. No mold, no condensation, just incredible comfort. The well water then goes out to water my garden, been doing this since 2000, it was as easy to do as it is Green, we should be doing this more, instead of making excuses about condensation.

Solar Hot Water

@ May 26, 2014 10:12 AM in Solar Thermal is Dead

Couldn't agree more Dragline, I have similar performance with my solar domestic hot water system, but have even much better collection at the lower temperatures, with my solar space heating collectors.The industry has been stuck too long "Solar Domestic Water Heating" for too long, we have to collect lower temperature hot water during the heating season, to make solar hot water more efficient.

To help Dan, thanks for all you do.

Thanks, Bob Gagnon

I Agree With Aaron

@ April 29, 2014 9:53 PM in Favorite Mod Con.

The Utica SSC is a great boiler with good support from the manufacturer, I wouldn't install anything else.

Thanks, Bob Gagnon

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.

Thanks, Bob Gagnon

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.
