@ August 31, 2014 9:43 PM in Weil Mclain ECO 155 gas piping design question

It has come so far since the old days of " sticking a big boiler in a house". Doing it wrong, you might as well stand next to the boiler and burn dollar bills, one after another. There's plenty of time to do it the right way.

Pipe Sizing

@ August 31, 2014 9:31 PM in I don't have 18"

One inch is fine for 4-9 gpm. A spiro-vent has none of those piping restrictions.


@ August 29, 2014 10:16 PM in Unbalanced Steam System?????????

Does each main have its own riser from the boiler header? Is that 70* first floor temperature an accurate representation of the whole floor, or just the room where the thermostat is placed?


@ August 29, 2014 9:51 PM in Oil to gas

If I were in your shoes, I wouldn't install a mod/con in my folks house. There are issues with a lot of folks getting use to the type of heat a mod/con produces. When properly set up, they heat the house perfectly, but older folks are use to cranking the heat to chase away a chill. The homeowner should be a little tech savvy, as they need to be involved dialing in the process of a mod/con. It all boils down to your father.

You need to change the way you look at your situation. The boilers will be installed before they are needed. That is the promise you make to the customers waiting,not a date or hour. Stop adding pressure to a stressful situation. Don't de-value your services by working weekends. You need that downtime to recharge. On Saturdays, you and your wife get a massage, play with the kids, go fishing, whatever.Sundays are for family dinners, church, picnics, and anything but work. Life will pass you by, and the older you get the faster it goes. Don't miss out on the things that make it special.


@ April 18, 2014 12:36 PM in Painting Cast Iron Baseboard Radiator – Baseray/Governale

The manufacturer recommends oil over latex primer? I'm not a painter, but that sounds like a recipe for disaster to me. I was told, long ago, that the oil would eat up the water-base.


@ April 14, 2014 9:55 AM in Two Circs - TT Prestige Excellence

Check figure 21, page 31 of the boiler manual. The 2 CH zones are for 2 seperate reset curves. For instance, one baseboard- high temp, and one radiant floor- low temp. In their attemp to provide all the info., they have made it more confusing than it has to be.


@ April 13, 2014 9:02 PM in Can a Circulator Pump Past a Stopped Downstream Pump?

There might be a government grant for that one. If you could fold enough facts in to the nonsense, they'd probably go for it.


@ April 12, 2014 9:20 PM in Proper Wiring Help Needed

I think he needs a Common wire SWEI. Oh...I see what you're talking about now. There's a "C" there.

Ya Know

@ April 2, 2014 10:28 PM in Need used or cheap commercial steam boiler

Not that it matters, but no one thought to ask this gentleman what the non-profit organization was,before criticising his cause. I have trouble finding the words.....SAD is the only one that comes to mind.

Yeah George!

@ April 2, 2014 8:16 PM in Need used or cheap commercial steam boiler

Maybe you could get everyone in the bank drunk, before the folks from the NON-PROFIT go in to ask for the loan.


@ April 1, 2014 6:04 PM in Thermal Expansion Tank

absolutely do need an expansion tank for DHW, if there is a PRV present.

"The new pex that we ran in the house is 3/4" runs, down to 1/2" to the taps/appliances, so I doubt it's the new piping. Something tells me more and more it's the pressure from outside the house".

Not 1/2"

@ March 31, 2014 7:41 PM in Navien 240 combi installed - I have concerns

He's got 3/4" from the main at 100+ psi. The drastic drop in gpm with multiple fixtures can't be attributable to that. I believe he said he had 3/4" with 1/2" to the fixtures. I don't know for sure, but there is the possibility that when he had a tank type water heater, turning the PRV down may have been someones answer to a dripping relief valve, in the absence of an expansion tank. Just a W.A.G.

I sound like a kid- OMG

@ March 31, 2014 1:57 PM in Navien 240 combi installed - I have concerns

Maybe the PRV is adjusted to 20 psi? Buy a $20 sillcock gauge. Make sure the sillcocks are piped after the PRV, and CHECK  THE  PRESSURE.


@ March 31, 2014 1:37 PM in Navien 240 combi installed - I have concerns

I guess 22 or 23 GPM to the house would not be enough.

Not Yet

@ March 31, 2014 1:20 PM in Navien 240 combi installed - I have concerns

As said....Check the pressure in the house. Is there a PRV on the supply where it enters the home from the street? With that kind of pressure at the main, you should not be having the problems you're having.

Jamie gets the prize! You've selected the one type of paint they say not to use on radiators.


@ March 30, 2014 12:03 PM in Navien 100,000 btu heating

I need some more direction to that webinar. Naviens answer seems to defy everything I've learned about P/S piping.

Pretty Sure

@ March 21, 2014 1:21 PM in Please critique this design

That strategy falls into the "Six of one...Half-a Dozen of another" category. Based on the definition of a BTU, it should take the same amount of time to heat the water to a certain temperature, whether you are alternating zones, or feeding the home as a whole. I'll stop beating a dead horse about the whole system. I didn't reallize you only wanted to talk about control and stop-gap measures. Best Wishes
