Anyone use the new Taco 0018e. How does it compare to the Grundfos Alpha2 in terms of performance and reliability?

    I think both are too new for anyone to have a good idea of long term reliability.  

    The 0018E has a lot of features, but seems like it would be overkill for many applications.

    We installed a couple hundred Alphas over the years. Only one dead one, my own house!

    yes, I have one in my home. love it!! it has three unique modes of operation, and I use the constant pressure mode for my 13 zone valves. 0018e blue tooth feature is great for dialing in the perfect pump operating mode, and know where your operating on pump curve. before Bluetooth technology, we would guessthemate where the pump is operating. I just went downstairs to take a picture of my system, and 1 zone is calling for heat, pump is running, so I connected using Bluetooth and see my pump is operating at approx 1 gpm at 10.5 ft/hd. now that pretty cool!
    for your reference, I attached two photos along with 0018e catalog. hopefully this was helpful.

    Beautiful install. Have you ever tried the propotional pressure mode? Makes sense to me that if more zones are calling it must be cold outside and you could probably use a bit more flow. :-)

    I have 9 zones in my home system, it is rare that I see more than 3 calling at once.

    Thanks for posting @Joe Mattiello Look at all those zone valves. I feel a little wimpy with only three zones at 25-30 feet each. btw - nice personal touch with the green plywood.

    Thanks for all the compliments on my system using 0018e. I should throw my radiant guy John Perry Advanced Comfort Systems a plug, he designed the board. More about my system, it's in slab heating and I'm using approx 105 degree water temp to heat my home. My heating bills are ridiculously low, and my house is at 71 degrees throughout. I have an indirect for DHW so the boiler only fires to high limit when DHW is calling. As for proportional pressure mode, I would consider that for one large zone, as opposed to zone-valves which constantly open and close, so pump continues with constant pressure when only one or more zone are calling. As you can see from my blue tooth curve, my pump adjusted to one zone calling for heat. I find it to be a real game changer. I just had a plumber come over for a quick plumbing job, and he asked me about the system, so I had him feel the pipes, and the pipes are close to body temperature, so they don't believe it's running. I remind everyone, my house is 71 degrees and it's in the thirties outside.
