Cold water and Cast Iron

Jason Horner

Sounds pretty good so far.

I've got cast iron rads too and I'll be ripping out the basement floor next month and installing radiant in the new slab, and I'll be adding some staple-up under the kitchen and entry hall floors (both are tile), and I'm finally going to get around to doing indirect DHW. So this should be an interesting mix.

I was at the Viessmann training for the Vitodens - both the training and boiler are first-class. And the tech support so far is excellent.

But the WM is interesting from a price perspective and it has a lot of bits included in the basic product that are extra cost items with the Vitodens. And WM has a better consumer heat exchanger warranty -- can't figure that one out -- Viessmann's warranty on the bi-ferral is way better than on the Vitodens -- I wonder why it's less on the Vitodens than WM.

Here's what happens.....

when you run a cast iron boiler continually @ 110*

Floyd_5

here's what can take it..

and...
better yet this boiler will NEVER cycle....


I'm gonna give this Weil a "real life" test...


24/7/365.... 120* in 140* out.......on LP


I'll let you's know how many days straight she can run!!!!!

It's all Dan's fault...

He made fun of me in that P&M article.......

So I HAD to try it out and see for my self...:-)

No, truthfuly, I figured that I had a perfect oppurtunity

here, to put one of these through a great test!!!!!

By the way... I have one in my house, and I have two Munchies

In a big log house that I did, also....

Can't wait now for COLD weather.....

Got some great new equipment to play with!!!!!

Is this the first WM Ultra you've installed?

What do you think of it so far?

I've been considering either the WM Ultra or Viessmann Vitodens for my home.

The Ultra.....

I have been playing with the one in my house since May....

It has worked flawlessly so far.. I have been backing the

DHW temp. down just to see how far I can go and still make hot

water. So far I am down to 90*, which lets the boiler run up

to 130*, I have the Plus 40 tank and have the t-stat on it

set at around 115*, I still have PLENTY of hot water!!!

Finally got cold enough in the house to turn the heat on,

Sat. night.... I sucker purred along @ 130* with condensate

pouring out.....my cast iron baseboard and old rads just got

warm... seems as though it should save me a bundle....

I think that I will need to find out how to turn the boost

feature off, though, I want it to run almost continuosly,

come really cold weather.

The one pictured above, is installed in a pig farrowing

facility...to warm heat plates for the little ones...

It is islated from the plate system with a FP HX as the

system is not O2 tight.....The boiler is modulating @140

which gives me 95* plates in the pig pens. Had to set the

boiler to think that it was making DHW... it worked better

in that setting.

It's pretty amazing, the boiler just purrs away and

maintains exactly 140* no cycling!!!! One boiler purring

along at 1/2 thottle has got to be way better that 2 -

250,000BTU boilers slamming on and off all the time.

And, this one is the 155....keeping up great, so far!!!
