hydroniCad

@ July 12, 2014 7:20 PM in hydroniCad

Looking at HydonicCad by Anthony Macars & John Siegenthaler, Would like to know if anyone has use this, or maybe there is similar software I don't know about . I need something to lay out tubing to show to builders and homeowners, for a better presentation
Like to show the lay out, different zones plus help us pick the best lay out pattern.
Thanks

blower wheel

@ November 4, 2013 8:35 PM in Knight boiler problems

A little recap, you have clean the heat exchanger, checked the vent pipes, redid the outside vents. and
Still having problems.
What does the blower wheel look like on the inducer motor? If you did or do have discharge air being suck in, the blower wheel will not look good. Do you have a picture of the impeller? you may not realize how bad it looks till you get the new one and compare.

The system I have seen that use 1/2" pex for snow melt are 6" apart and 150' long max.

May check to make sure the expansion tank is size correctly, had a similar problem on new 5 story building. Tank was under size.

taco wet rotor in the shop with a bad capacitor, got a price from taco for a new capacitor. Price was high, better off replacing the whole thing. I should get that out and look at it, again. was always going too look elsewhere for one, but never have.

hard too say

@ February 3, 2013 7:41 PM in Weil-McLain GV-4 longevity issue

not sure what the expected life is on that model. So many variables that affects a boiler, I,m sure you know this. I would hope you could get many more years out of it. 19 years don't seem that old.

Installing a 800 sq. Ft. patio, Installing 3/4" pex 12 inch centers. what are some ways to turn the system on and off automatically with out spending a lot or is there.
Thanks

Seems it would be better and cheaper to just do all the roofs. There already made. Just need to be installed.

Is there problems with using

@ April 2, 2010 12:14 AM in Is there problems with using

a 80 gallon indirect tank with a 150,000 lochinvar boiler? This job started out with a little in floor heat (load 48,000 BTU) Now they would like to get rid of two rinnai water heaters and use indirect. Its a 3 bedroom house with a 72" jacuzzi,
It was suggested to use a 45 gallon tank, I'am a worry about being able to fill the tub, do I have a concern or just nuts?

I did staple up with

@ January 3, 2010 7:35 PM in Onix radiant heat

extruded aluminum plates. I went back and forth between onix and staple up.
I try to find all the information I could on both. I decide on staple up mostly from what I end up reading in there manuel. They say with there onix over pex you need to run the temperature of onix several degrees higher. I figure the idea with a mod con is to run your water temperature as cool as possible. Plus the extruded aluminum plates just make sense you will get better heat transfer. I have had the plates it in my house now for two months, its working great. Nice warm floors and no noise at all!! It is more work then onix but so far worth it. I installed in 1/2” pex in the big room and thinking of going with 3/8” in the smaller areas. The 3/8” should be more flexible and easier to work with.

use siggy equatiion

@ January 3, 2010 11:44 AM in buffer tank?

to come up with the buffer tank size, that equation does not compestate for the boiler modulating. I would think if any one had a equation to compensate for the modulating. It would be siggy. I have some his books but could not fine a equation for it. What I want to do it calls for a 80 gallon tank according to the equation. But by gut feeling (plus NRT_Rob post) is saying a 30 would suffice,
As far a buffer tank size, too big shouldn’t be a problem.
Plus with the Ramp delay, gradient limiting. You would think you could get a min 10 minute run time with a 30 gallon buffer tank.

sizing

@ January 2, 2010 10:23 PM in buffer tank?

If a person was to use a buffer tank. It seems as if it would be beneficial for small micro zones. How to size a buffer tank seems a little tricky. The larger the temperature rise the smaller the tank size. If you have a 75,000 BTU boiler with a 2000 micro zone and a temperature rise of 60 degrees, a 25 gallon tank would do. If you had a temperature rise of 20 then you would need 75 gallon tank. This is if you want a min run time of 10 minutes. But with a mod con boiler it would start to modulate as it approach set point temperature. So you would think, you could get longer then 10 minutes? Any ideas on this? I want to keep the temperature rise as small possible to get maximum efficiency.

buffer tank?

@ December 27, 2009 5:04 PM in buffer tank?

Putting in a knight boiler 80,000 BTU, with indirect water heater. A coupler of the zones will be small, staple up for one and wall heat for other, maybe towel warmer. Wanted to see what some of you have done. Would a Buffer tank be good? I seen the boiler buddy, does this work? Or is there some other ways to keep the boiler from short cycling.
Thanks

@ September 14, 2009 8:59 PM in Gravity Hot Water

for the help, I like the TRV idea, and not having to do any thing with the air vents. There is no way to do reverse return. Will look for orifices on the 2nd floor. The system I'm looking at  looks just like the one on page 8 the How Come book?


Plan on converting it to a 95% boiler with P/S piping, indirect water heater ( plan on doing it only if I feel comfortable doing it). Mostly have pipe up new systems with pex, indirect water heaters and hot water A/H.

Still confuse about the piping on page 28, if there are any links to more information, or drawings that would be great . Thanks again.

Gravity Hot Water

@ September 11, 2009 10:24 PM in Gravity Hot Water

Customer wants to convert gravity hot water, there are no pumps now (will be adding a pump) in the system, they want to go to a high efficiency boiler, with indirect water heater. read Dan's book How Come? very informative book. I do have some questions I'm hoping  to get some help on. First one would be on the radiators , there is the incoming water with a angle valve at the bottom, the return on the opposite side at the bottom. The air bleed is at the top on the angle side. Does this air bleed need to be moved or is it O.K where its at?
Thanks

@ April 30, 2007 12:05 AM in Snow Melt

Thanks to all that post, you all have given me a place to start and lots of ideas for installing a good snow melt system. It was great to see those pictures Glenn, very nice looking jobs, a picture is worth a thousand words. Never even consider edge insulation, until now. Has any one ever used track railway to fasten down the pex? Thanks again Mike J

Snow Melt

@ April 28, 2007 10:01 AM in Snow Melt

Looking for ideas for a good snow melt system in NE. If you could point me to on line information, or email me with articles or suggestions. Its going to me a 2300 sq. Ft. Drive way, with 4 concrete. I do plan on insulating under it, is 2 of insulation over kill or is 1 enough. Is it better to go with smaller pex and more of it or larger pex for more length? I have done some in floor, Do you need to cut down on tube length compare to in floor, Thanks Mike J mike@jardeemechanical.com
