Hydronic Supply

Some of the codebooks don't allow for fluid in the supply side of a hydronic system to enter a tee fitting through the branch opening, but overall these jobs look good. Keep up the good work.

What do you mean?

I think he means...

the bull headed tee. Actually, I'm not aware of any code issue regarding this. They do it in plumbing ALL the time. The problems with doing it in hydronics is that we don't typically have 70 PSI worth of driving force behind our systems like they do in plumbing. We typically have around 7 PSI driving force, and you don't want to waste ANY of it. A bull headed tee will waste a lot of pumped energy.

Besides, water is dumb and lazy and it can't make up its mind. "Do I wanna go left, or do I wanna go right, maybe I'll change my mind..."

Other than that, it looks good. Especially the future hydronician:-)

Ahh I think he is looking at the

1st picture. There is a primary pump inside the GV Weil Mclain boiler. That is piped per manufacturer specs. It is hard to see but there is a cross over between the supply and return. Also there is a pump in the main loop. Not a big house but it had rads and I wanted to be careful with return temp.

Bullhead tee's

International Mechanical Codebook 2000 1206.1.1 doesn't allow the supply to enter the side of a tee. So when the water comes out of the boiler on the supply side, it can never enter the side tapping of a tee, it always has to hit the bottom or top, and then split off the other two taps. They justify it by saying the water won't flow evenly to both sides of the tee, and the flow reduction is too high to allow piping it that way on low pressure systems (hydronic heat piping). Domestic water piping is accepted that way, but not heat piping. It makes it a real pain, and you can't make uniform looking manifolds like you did with it. The work looks great, and many of the places aren't under that codebook, so it depends on where you are as to if it will apply.

Interesting

I was looking in the instalation instructions of that Weil Mclain GV boiler and they show it that way. So much for that. I will probably be ok if I just switch from the bull to one end next time. Then go up to an elbow and there you go. I will do it that way next time. I will assume(theres that word)that the code is correct.
Thanks

Nice work Paul

Do you get to install the EK often ? I think we are gonna try to fit one under the stairs in a Levitt house , but looking at your pics , the boiler is kinda wide .

How was it connecting the crossover pipe on the oil tanks ? I believe NFPA code says not to use swing joints on the crossover like you did , but what a **** to get it just right .

Keep up the good work Paul .

Paul Mitchell

Ron

been doing alot more Eks lately. But there is no swing in the cross over. 2 close nipples 2 els 2 more nipples and the union thats it. Only swings are in the fill and vent.
Thanks

clean out

on the EK is in the rear of the boiler Ron,

i know you love a challenge but I think you will find it hard to give access . What will the sales men come up with next?

All the best,

Robert

Sorry

about the swing joints , I meant to say you did it correctly , by code . Makes it harder to install , but the less joints , the better .

How is the noise level on the EK , compared to conventional boilers ?

Unknown

I have a brochure

for the System 2000 Frontier that says it can be completely serviced from the front . I was taking measurements for the boiler over the 40 gal tank and I don't think it would fit under the stairs . Maybe if we slid the tank behind the boiler . But then comes the challenge if the tank leaks in the future .

By the way , where does the fluepipe come out of the EK ?

Robert O'Connor_4

I haven't

seen that one . i used to work for a company that intsalled the EK's. Learn something new all the time I'll have to check out their site.


the Ek breech is on the lower left side.

All the best.

End connect

That's what I normally do. Don't get me wrong though, the job looked great.

Paul Mitchell

Noise is night and day...

Sounds like a microwave running.

That is a frontier

with a standard base. we install them for ease of cleaning. Frontier breech is out top and if I am not mistaken so is the standard ek now.
