How many zones and how many different temps?

Here's one of our latest projects.My only regret was the customer insisted on using OSB on the wall.

Nicely done.

There's a lot going on there! Nice work.

Nice, what is that control?
I hate OSB as well.

That is a Honeywell AQ 2000
I don't like the OSB either, but the customer is always right

The biggest problem I see is your going to have poor flow with all the valves closed lol, very nice, that's the jobs I like to do.

Im sorry but I'm actually jealous, I'd like a job like that.

Fantastic work. I would love to do some pipe work like that

Nice, neat work. Beautiful piping. Are you using CPVC for the combustion air intake as well? It is hard to tell from the photo. - DF

Luckily only one temperature. We either use a Honeywell mixing valve to reduce temps, or an injection pump. The Honeywell AQ controller takes care of all the work.

I enjoy them as well. We usually get about 5 a year. This one was the largest yet.

Because of the indirect storage tank for dhw, we need higher temp PVC pipe in Canada? So the exhaust is CPVC and intake in PVC dwv.

Can't you use non cell core PVC with the red writing?

We have to use the stuff called 636 from IPEX. It may be a load of BS but that's the code here. Viessmann had trouble with the PP venting they had available for a while too. It seems they had to develop local testing protocols for venting that had been in use in Europe for a looooonnng time. Big waste of money if you ask me.

Whats up with the LWCO, do you just have it on a riser with an auto vent? We have to use them also and they always screw the job up.

Yea, officially the pressure switch in the boiler is not recognized as a LWCO. We are supposed to put it above the boiler but an autovent is not required there. Where it is put depends on the system design, of course.

In Canada we have to use "System 636" PVC or CPVC.

The LWCO is in our gas code, (when there is radiation below the boiler), even though the boiler is quite capable of shutting down in the event of loss of water. I keep thinking of not installing them, but I always end up. Always ad an air vent, works well.

I was just wondering about the way you did it, I always put them in my primary loop and it messes with the way I want to pipe the boiler. It looks like you just put it on a riser with vent which would give you better options for the primary. We have to use them too, I didn't install one once and never got nailed.
