HTP EFTU Boilers

mattbee24

Apparently, HTP will be discontinuing the UFT series boilers soon. I've been told they will now use the EFTU series as a replacement. Has anyone has any experience with these units? I'm not sure if I'm a fan of having a pump included with the unit. From the looks of it, it is a Taco pump. But not a standard one.

Maybe  the boiler modulates pump speed also? It’s not uncommon for pump manufacturers to build OEM circulator for boilers, etc

The spec would be the same or similar to a circulator you would buy to match the boilers requirement.

I haven't seen one myself, but I know a gentleman out East that has been using them for several months now, possibly even a year. He cannot say enough good things about them and their new Italian made HX versus the Korean one in the UFT. With the days of primary/secondary being almost mandatory now, the internal circ is super handy IMO. I do enjoy the direct piping capability of the UFT when applicable, but I can definite;y see why they're going to an internal circ. Perhaps the flow requirements of this new HX are higher and they just want to assure it's met

Or people were't reading the manual and maintaining the minimum flow.

I guess I'm just a little anal about pump specs...I looked through all the info, and I can't seem to find anything on it. The only thing I see in the manual is you can use the internal pump as a system pump for "systems requiring no more than 9 gpm at 9 ft. of head pressure".
In the parts breakdown, it shows the same pump for all the models. It is described as "PUMP ES2 3VK 63-7C-C US".

hot_rod I looked at those, but wasn't sure which one it was.
I did find a pump curve in the manual, it's just strange to me that it's the same pump for all the different size units.

The manufacture has made parts interchangeable between its boilers..
If you search youtube, they have a installers video,which talks about how parts are the same between different btus of the sameboilers...sort of a one part fits all approach.
If you read the sales brochure, htp makes a claim that with the internal pump, primary/secondary piping is not required, thus saying on installation costs...

I have one. Boiler only 199. The Ariston design is far superior to the Kiturami stuff. Taco ECM pump, Honeywell GV, EBM blower. Runs silent. The Kiturami stuff really hurt HTP. The WiFi still feels behind the times compared to other brands.

Thanks Timco! That's good to hear!

Whats exactly wrong with the kiturami hx in the uft? Mines 4 years old, running just fine.(Did I just fck myself)😂

I just got word from the factory this afternoon that they're NOT discontinuing the UFT.

I'm also not so enthused with the internal Italian circulator because if it goes out, neither my distributor nor myself will have one on hand. And we all know that if it goes, it will on a Friday of a three day weekend and the coldest night of the year.

I've always got a ups15-58 on hand if one goes out, which is extremely rare.

Installed elite ultra combi unit yesterday in jersey, lets see how it goes. The kiturami attempt at mod con sucked for HTP

Interesting...makes me question my rep.

That is another reason I'm leary about it. If it were a standard pump, I wouldn't mind it so much.

All this hate for the kiturami. But no facts why it sucked.

hot_rod

same happened with Gianomi / Semerta

which  is still a fine tube HX in my opinion. I’ll take it over the fire tube design

I've read thru the manual on the elite ultra to try to understand the integrated ECM pump but can't find anything that describes what/how the pump speed is controlled.  I've been working on building radiant floor system with the old UFT 80 model paired with a delta t pump.  The system was designed so that the area of my house that loses the most heat and is also the area I am in the most is one zone that is "always open" and large enough to avoid short cycling.  Additional small zones for bedrooms would run off that would be controlled by a local valve.  So if these were open)demanding heating it would make the main zone bigger, more heat output, return t drop, delta t pump respond by increasing, boiler respond by increasing fire rate   

Not sure how this system would work with the new ultra. Any ideas?  Is the UFT model being discontinued or still in production?

Thanks

The UFT series went out of production last quarter 2020 and the remaining UFT80 stock was sold out by the Jan 2021. Last UFT100 sold out in September 2021, it may have been me. I bought one for spares for my UFT80 units around then.
