The Is there a direct vent gas fired conversion burner? Not sure there is one....

@ May 4, 2014 9:45 PM in Pipe size to cast iron radiators

sure that will not work right.
I looked at a similar system years ago and they were tring to do that w/ 3/4" pex....didn't work either.
I ended up installing a set of manifolds (s&r) w/ 6 ports (for 6 rads)  and ran 1" to the manifold. 1/2" pex to each rad. I set the new boiler up w/ a outdoor reset control and the system worked very well.

They do require...

I don't see why its needed.... but ya some folks just make it up to be extra safe....all it does really is add to the cost of an install.

Mixing valve on Tankless...?

@ April 26, 2014 8:14 AM in Mixing valve on Tankless...?

Anyone ever heard of an inspector requiring a Mixing valve on a tankless WH such as a Noritz or a Rinnai?
A coil I can see...and would do. But an appliance that has the control set to only do the HW.....hmmm. What code would he be thinking of?

I remember....

a few years back seeing a picture here of someone doing just that over in China.... Oxygen would be the biggest problem.
It semi fragile nature another.
With pex being so easy to work with cpvc doesn't make sense to me.

sounds like....

either your old circ or your new one, has a rotated flange....I would get the proper circ for the application.

How is the water....

Glenn is a true gentleman. Miss seeing him around here and at trade shows.

@ April 1, 2014 7:44 AM in Superstor sidearm problem?

descaling treatment is to.... drain the heater, run the hot water zone through coil, pull out the aquastat well and using the coldest water you can spray in cold water onto the superheated coil. Usually this is done w/ a wand made from 3/8" soft copper tubing w/ a bunch of small holes drilled into it. This will shock the scale off the coil.

hands down. The toughest, most reliable unit I have used.

If the system....

@ March 29, 2014 9:00 PM in Entran III

had std glycol added to it is could make the entran more brittle and plug it. I had this happen one time and the entire staple up had to be removed. Rhomar products a re great. Be careful about adding top much of anything as it could make the system degrade. Flush w/ good quality water and add the inhibitor from Rhomar.
Watts makes the Onix tubing so any supply house that carries their products can get the fittings. If you are in the NE FW webb has them.


@ March 28, 2014 6:25 PM in Entran III

E3 was orange and it did Entran 3 written on the side. The fittings are generally speaking the same as the Watts Onex that are around now....Barbed w/ tension clamps. The stuff is brittle so be VERY careful.

So there is....

@ March 15, 2014 8:46 AM in Caleffi hand pump question

a difference! I have asked several supply houses and they look at me like I am nuts. I tried the double hose washers....not so great. Big mess w/ the tyfocor.

@ March 14, 2014 5:20 PM in Steam radiators without bleeders for hot water system

You can use all radiators for steam but not all rads for hot water. If your radiators sections are not all connected at the top you cant use them for hot water. On a hot water system the vents go at the top of the end section... on steam it goes mid section.

sounds like your ....

@ March 9, 2014 2:45 PM in What is this?

system could use some TLC. A cleaning and some air vents replaced. What does the system have for an air separator?


@ March 9, 2014 2:36 PM in Hydrotherm Celtic and a 15-42

If I cant find one soon I am going to see if I can go in a find a way to adapt over the piping that is there and see if I can add a new circ outside of the cabinet.

Here are a few.....

@ March 8, 2014 5:52 PM in Hydrotherm Celtic and a 15-42

Pix. It's still in great shape. And is around 82%. It's 50k input. 41k out. The food has only heatloss front and back. None to the sides.

Yes I have....

@ March 8, 2014 3:05 PM in Hydrotherm Celtic and a 15-42

I cant see replacing a boiler in such a small space, that does not cost a good deal to run and runs fine. Sort of like ditching a car because it needs 4 new tires.

Hydrotherm Celtic and a 15-42

@ March 8, 2014 8:15 AM in Hydrotherm Celtic and a 15-42

Anyone out there on Wally World have an older but still operable Grundfos 15-42? Say from the mid to late 80's? I have a customer here in NH that has a Hydrotherm Celtic 50k input, that still works perfectly fine. Mfg date 3/1984. Some other contractor decided to replace the circulator. Instead of searching for the right one he installed a 26-99 in the frame that is built into the boiler...a newer 15-58/42 is too small. Now they are having air issues because the 26-99 is way oversized.


@ March 6, 2014 6:45 PM in High Duty baseboard

40,000 btu on 3/4" copper. So if normal baseboard is around 600 btu/ ft that is around 66/67Ft.
You could go more but your output will not be 600/ foot after the 67'.
Typically high output is 750/ ft. (ie.. Sterling Senior)
That puts you in the 53' range on 3/4" copper
