Low Temp Baseboard Piping

pipe4zen

Looking at Smith's "Heating Edge" brochure , they show a number of ways the btu output of the two 3/4" elements are effected by different piping configurations.

With the two supplies method the output is the greatest.



My question is , if I wanted to replace existing baseboard with Heating Edge, but only have single 3/4" feed, Can I use a tee to accomplish two supplies method with flow for top and lower elements the same direction into a tee'd return piping.



Boiler would be replaced also to mod/con.

Absolutely

Yes,

You can achieve higher outputs with tees. Be sure to equalize the tees by either equal headers or reverse return methods. Keep in mind you will not get to the full 4 gpm rating per pipe using your single 3/4" supply.

Another possible "side effect" is that by pulling the extra btus out of each register the water temp going to the next register (I am assuming you have a series piping arrangement) you will reduce the heat output to down stream units. I would evaluate this before jumping in.

2 rads?

With only 2 rads the temp drop is probably not much of an issue. To do it correctly you should upsize the second rad to account for the lower temps. The piping you show will favor the upper pipe. I would put the tee centered between the 2 pipes and 90 into it.

I

believe he would merely split the available btus and not get the desired increase using that approach. Increasing the supply to 1" would work?

i would do this

unless you want to fry them, 3/4 more than enough in my opinion.

I saw that Chris, but...

The outputs are only slightly better than regular high output baseboard. You can get 560/530 out of Petite 9 at 150 F. The Smith stuff is somewhat better, but still not enough to justify the cost in my opinion.



The problem is that it is still convection. In order to create convection, you have to produce a high enough Delta to cause the air to move.



Just one dude's opinion.
