the pex joints

@ March 13, 2013 10:00 AM in pex on condensate loop

is not whit's at u have to worry about, it's the pex. as long as u make sure use a heatpex (it's pex with an oxygen barrier) and do not exceed the temp/pressure limits u will be fine. pex is being used on residential heating systems more than anything else, so all the r&d is taken care of.

if the rads r free

@ March 13, 2013 9:38 AM in unusual use for a cast iron radiator

you can put as many as u want into the tank and it will be economical, compared to a large plate ex or 2000gal of mfrd. storage tanks. so this is going to be a concrete tank? where in the basement? r u worried about moisture/humidity, smell, excessive heat transfer to the air? i personally love the idea of having as much water storage as possible and heating it with a wood boiler a few times a week, it is part of my dream system!

pro press

@ March 12, 2013 10:44 AM in Propress valves

is the best invention for large fittings. use a 3 pp ball valve, don't use adpt. unless u r using the adpt. to take up the difference so u don't have to buy a piece of 3" copper and coupling. the best way to clean off the solder is to heat it up then wipe it with FIBERGLASS INSULATION not a rag, trust me. u will be able to wipe it so smooth u won't even need to sand it after, but i do recommend sanding it. good luck

 this is the one i have. it comes in 2 sizes one for 1 1/2 and one for 1 1/4. but it's not the old hammer type, but still works good.

THAT IS SO AWSOME BOB

@ March 10, 2013 3:41 AM in do u know what this is?

 i would love to see pics, at least of the duct work, if u got some, or have time to take some,lol!  in your wall and ceiling radiant, did u use small capillary tubing, or standard ?" O.C. 1/2 tubing?

thanks bob

@ March 9, 2013 10:30 AM in do u know what this is?

i would love to see some photos of the finished product, that would be cool! maybe if u got time u can post pics of the whole system too. r u able to get below the dew point across the board in cooling season to handle all the dehumidifying needs? do u also cool with the radiant?

do u know what this is?

@ March 8, 2013 9:42 AM in do u know what this is?

what is this custom hx being used for? how is it being used? here is a link where i found it and a little info, but not enough info. has anyone done this before? maybe this post will find the designer

YES

@ March 8, 2013 9:27 AM in Hanging a circ

U should put a hanger under the motor. i always use threaded rod and uni-strut. but i always say every time i do one, i wish they put a spot on the pump to put threaded rod thru.

that's what i was looking for....

there had to be a major downside to this. ant farm!lol! thanks

what he did

@ March 5, 2013 9:07 PM in sand for heat tranfer media?

was staple down the tubing to the floor 6"OC with sleeper 2x4 in between, then poured sand on top of the tubing. he had that expanding spray insulation under the sub floor in between the joists. my first reaction to this was a bad idea, cuz of the air in the sand, so  he used a hi density sand and his argument was, it is  like having stone (or concrete) a hi thermal mass. i wish i had a FLIR!

sand for heat tranfer media?

@ March 5, 2013 10:28 AM in sand for heat tranfer media?

 a buddy of mine is building his home and it's a log cabin, but huge. anyway, he is always asking for advice, but never want help with the labor. he usually finds my insight really helpful and takes it, but he came up with the idea of using sand to enhance the heat transfer of his sleeper radiant system. it kind of sounds like a good idea, but i never heard of it, has any of u guys done this?

BRING THE PRESURE

@ March 4, 2013 8:46 PM in Boiler has too much pressure

 down to the pressure needed for your system prolly 12-18psi. once u do that shut off the valve that feeds the boiler for a day or 2. if the pressure doesn't rise we found the problem. so u say the pressure from the road is high how high? you might need a pressure reducing valve for the house to bring it down to a manageable pressure. u might also need a new prv 4 the boiler from being over worked.

i new that

@ March 4, 2013 10:34 AM in Chilled ceiling design

cold air is more dense and can hold more humidity then hot air, brain fart i guess! know why not just put the cold dry air back into the home without reheating it? is i because it will cool down the home to fast and inturn short cycle and not pull the humidity out? but then why can't u just down size? maybe i should find an artical on this and read it!lol!

this is

@ March 3, 2013 9:33 PM in Chilled ceiling design

all uncharted territory for me, but i like it. let me see if my theory on your design is correct; u first heat the air using your compressor which increased the amount of humidity the air will hold. then use the cold hx to extract the humidity better, because it doesn't get nearly as cold a refrigerant. But then i ask,  if the cooling tower your using is cooling the water with refrigerant, and not a "swamp cooler type chiller", then y not just use a refrigerant dehumidifier, "a smaller ac system" insteed of a chiller and preheater?

what do

@ March 3, 2013 7:25 PM in Chilled ceiling design

u have to do yo convert your ac to dehumidify? i would think that all u would need to do is downsizing the tonnage

how r u

going to control the condensation (humidity) if your costumer doesn't have room (or doesn't want) ductwork?  i am very interested in this topic, cuz this is something i want to do in my place.

@ March 3, 2013 5:22 PM in Laars endurance EBP

post a pic of the sensor where it goes into the tank? i wouldn't think u have to drain the boiler to take it out.

thers a couple things u can do

@ March 2, 2013 9:31 AM in Boiler has too much pressure

u want to check to see if the PRV is not faulty. bring the pressure down to where is needed for your system them shut off the feed to the boiler; if the pressure still rises then it it's not your PRV its somthing else. fyi, the back flow does not have any affect on pressue. so now u want to look at your exp. tank, tap it does it sound hollow, it should. the only way to check the pressure in the exp. tank  is to remove it from the system presure. if u find that it's ok then move on to the tanklesscoil (if u have one). that could be leaking into the boiler and raising the pressure. try this stuff first, and let us know how u make out.
