What is the preferred pump for radiant?

Tom_35

What pump do you prefer to use on your radiant systems and why? From some of the pictures that have been posted, it appears that Taco is one that is used quite a bit. We originally used Grundfos, and have also used BG.

Taco

I like them, have had few problems, have them in my house, 20 years old, knock wood.

It depends on the pumping requirements. But Taco is big here and I'll use Grundfos

Make mine

Grundfos. In the small wet rotor catagory I have had the best luck with this brand.

The 15-58 Super Brute with it's 3 speed motor, (use the lowest speed to handle the job match the pump and system curve, and save electricial energy), built in check on the discharge side , and excellent warranty make this a clear cut winner. From a progressive company that builds 10 MILLION wet rotor pumps a year.

I agree

I agree with Hot Rod 100%

Taco makes a great pump........

although I use Grundfos almost exclusively. The 15-58 is the most versatile pump around and with the addition of the new 15-100 for those jobs using Slow Tedious Trak, Grundfos has the pump I need.

Taco OO series

Taco has a great pump with unique attributes. The cartridge assembly is a replaceable item reducing your replacement cost, and time. Additionally, Taco offers a 3 year warranty on the cartridge which helps make Taco the obvious choice. Taco also has many choices to include variable speed circulators, and the latest, and greatest radiant mixing block facilitating the piping, and wiring. I’m sure someone can elaborate about their experience with Taco, products. Please see attached for reference.

I like the 15-58 also, but would prefer them in blue

If only the boiler manufactures

would ship a Grundfos 15-58 with their boilers! Sure would give the installer a lot more ability to size the pump to the actual load

Sorry guys

Anything but - Grundfos.

I'll never forget when I too jumped on their bandwagon (admittedly, 20 years ago) and ate everything I installed - because the starting torque was so poor, the rotors would always get stuck after summer shutdown.

When we approached them on the failures, they acted as if I was the only one who had the problem.

I don't forget stuff like that. If the pumps were free, I'd still stay clear. Between the defective design and the stonewalling, I wouldn't give them the time of day.

Burn me once - my fault...

Seriously Ken

a 20 year old grudge?!

I had the same issues with them but gave them a second chance after only one year in the penalty box

I also had 8 out of 12 of a certain green brand zone (zone circulator) fail to operate right out of the box. I jumped from the pan into the fire on that switch!

It's because of you and other contractors that Grundfos has the best pump, and warranty, on the market today.
Thanks for complaining.

Grundfos

I have been installing Grundfos for the last ten years at approx fifteen pumps per month, and can count the number of failures on one hand and that would be three and one was the installer(that would be me)puting the screw for the cover through one of the wires on the capacitor, maybe I have been lucky but I have no reason to change at this point.

Many years ago and far away i too thought they were all That

and a bag of chips:) the Big grunfoss had a bad go round or two...trust me on that one. i remember the first taco i saw and fell for it immediately...no screw to frick with ...and no sticking impellers and no changing capacitors out For sure on the 3 speeds...however...i think of them as the first and i will always go with the pump that fits the bill not just could fit...so while i like Taco pumps i also go grunfoss when its thier turn at bat and have no regrets... this makes me think of a group of :...." well, we dont make the pump body for That pump anymore buh we have a new motor and rotor for it and then :"well if you would have come in last year we could have given you a New replacement pump for that three phase pump and motor "buh the new pump DOESNT Look ANY thing Like these... and i dont even think they will fit right...and a slew of other conversations ive had over the years

We had our home's system redone a while back - we ended up replacing the two trusty old B&G 100s with Taco 007s. The tacos are amazing - you can stand next to them and not hear them running. Naturally, upstairs - no noise at all. Gone is the old whirring hum B&G noise of my youth

We had good luck with the old B&Gs though. I hope the Tacos hold up as well....

heaterdude

beautiful job

love multiple circs, but how many gpm do you think you are moving through that boiler when all are on? Zone valves do have their place

heaterdude

I agree

with your multi-pump comment, but what really cheeses me off is the multiple boiler drains for purging each loop. 12 boiler drains, 12 places to leak, 12 times to connect and reconnect the hose. One boiler drain on the supply main b4 the boiler isolation valve-with feedwater on the other side of the valve purges all zones better, faster & cheaper- with less chance for drips!!
