Crown Install pics

Hydronx_2

I am a newcomer to the Hydronics contracting business. This is my first job from start to finish. It is a 70 year old house that the contractor is doing major remodel work on. The house was heated with a one pipe system with heavy style baseboards upstairs. The basement was heated with the mainline pipe that hung down about 12" from the ceiling around the whole perimeter of the basement. A very simple system, but the contractor wanted to get rid of the pipe eyesore in the basement and do away with the baseboards as well upstaires and put the heat into the floor. He gutted the entire basement, red shag carpet an all so we could put thermofin up underneath the floors. The boiler was still working fine but it was vastly oversized and sucking alot of btus. I think the new crown probably uses about as much gas when it is firings as the pilot did on the old burner. It was originally oil fired but had been converted to gas. The inspector told me it was a model that could be used for burning coal as well with a large door and space above the burner. Well enough yakking. Here are some pics of the old as well as the new. Let me know if I should have done anything differently, I'm still learning ya know.

Great Improvement!

I like the use of the Unistrut, the neat layout of the Grundfos 15-58's, the installation of expansion tank and airscoop "upstream" of all the pumps, etc.

It's an interesting piping arrangement. I like the size of the "primary loop". It took me a while to decipher what was going on, until I put on my thinking cap and combined a conventional CI boiler with radiant floor temperatures... aha!

From what I can tell, the radiant circuit is fed by a 15-58 on a very small supply pipe. Presumably, this is an injection circuit to keep the radiant floors happy? Which Tekmar are you using to "pulse" the injection pump or can it run continuously?

Lastly, considering the installation, I am surprised that you guys didn't install a condensing gas boiler. The low floor temps would have helped efficiency a great deal and it's an ideal DWH source also. Was it simply a question of too many $$$ for the condensing boiler? I simply wonder considering the huge scope of work elsewhere.

If there is one nitpick I may be allowed, I would consider installing a pipe to run the overflow from the water heater T&P closer to the ground. 6" clearance is customary.

Nonetheless, a very compact, neat install. Congrats!

Thanks for the comments. It is run by a Tekmar 363 with the injection pump running continuosly when there is a call for heat based on outdoor reset. The choice for CI boiler was mostly $$$ and the original thought was to put some baseboards in the basement. My next bids will have the vitodens priced more closer to the CI now that I know a little more of the work involved in building up CI for floor temps. The condensing would also give it a much simpler look as well. It was a little difficult explaining to the contractor the need for all the gadgetry when all the old system had was a boiler, circulator and expansion tank.
The plumbers still had to come back and finish connecting up the DHW tank.

Nice neat work. You have pride in your work, nice to see.

Very nice

I like the plastic inserts in the holes for the pex. I've been using them for several years now. It shows attention to detail and an intent to do things right. What did you use to staple the plates to the sub floor with? Everything looks great. WW

staples

used a senco sks N staple gun with 7/16" x 5/8" staples. The biggest problem I had was the dirt and crap that would come shootin out from everywhere up under the joists after firing a staple. I just did some fin in a new house and it was so nice to have a flat clean surface to staple to.
