Ultimate circ selection on Vito 11-44

GW

that's another reason why I went with a temp circ, I was thinking about the stratos. I guess it's available in mid-jan?

I just realized I'll drop more money for the 0012, it would take me about 20 months of steady operation before the 0012 pays for its higher cost.

watts up?

I'm picking away at my masterpiece. I lit up the 11-44 the other day (actually new years day, what a way to bring in the new year); I slid in a 15-58 just to get some heat flowing in one of the shop areas.

After plotting out the curve it seems like the 15-58 just barely works out, but I'm not sure what the stadler spring check is offering for head loss. I am simply piping this boiler in injection fashion to a primary loop above the boiler, so a pri-sec with a pri loop above the boiler circling the boiler room with its own pump.

I certainly don't won't to go too small, so I considered the 26-64. I picked up a couple at the friendly supplier and was about to install it (the heat circ for now, DHW coming up) and noticed the sucker is pulling 185 watts or so... made me stop and pause. It also seems the 26-64 is on the larger side of the scale (pump ability) after plotting that pump out.

So, here I sit, trying to keep the system all euro, but it seems like the 0012 has a nice curve, and it will save me about 30 watts or so. Shall I slip in a couple of 0012s?

I hate to sound like a miser, but by the time my masterpice is in full operation I will have (and if I opt to heat the entire 8000 sq ft, not gonna happen anytime soon) I will have (NOT including DHW pump/recirc, the small foyer which I may need two pumps becasue of the need for a HX, a pump for the showroom hydronics, a pump for the ice melt side walk) 7 pumps going...so forgive me for wanting to be tight watt (pun). Thanks for your opinions.

The one toy that my toy box still doesn't have is an ultrasonic flow meter. Once I drop the ching on that I will indeed have all the toys.

Gary,
Look at the Wilo Stratos. It will fit any curve you need. The curve is set by the installer for Delta t or Delta P control and draws very low watts. You are in Massachusetts. Call Sweeney Rogers in Raynham they are the rep and a great bunch of guys. If you need any pricing call Corey at Delta T in Franklin 1-508-528-6660. I think you will find everything you need with this Circ.

Stratos


The Stratos has been available for quite a while. Stratos Eco as you said.

ROI, less than you think.

E-mail me Gary.

Home again

Just checking in, Mark, your email address is likely gonna show up in my inbox at the office; I'll email you tomorrow. i thought the commercial stratos was out now, and the residential version was coming up this month? I'll be a little bugged if I got the wrong info becasue I talked with the Wilo rep about this exact subject.

As far as 'saving energy', is it true that the stratos can do the same work at less cost? i understand the VS virtues, but is that what the deal is?

same work with less watts?

I understand ECM blowers and the whole gig, but are you saying this will do the same work as a regular Taco or grundos and operate at less watts? tell me where to sign up, that seems to be a no-brainer. Are you sure?? With ECMs (warm air) the motor consumes more wattage as it works harder.
