1st two are still running STRONG after 13 years
We are replacing a B&G pump (that has been replaced at least 3 times..don't think they do well with chemicals added to our 750 Waterstove)We have a total of 3 pumps on the waterstove...we should have gone with the TACO on the 3rd pump from the beginning.

TACO 0011 PUMP
MADE A BIG DIFFERENCE WITH THE HEAT IN MY HOME. BEST PUMP I EVER BOUGHT!WE HOOKED IT UP TO THE WATER LINE COMING IN FROM OUR OUTDOOR FURNACE TO CIRCULATE THE WATER. WE REPLACED THE 007 TACO PUMP WITH THIS ONE. MAJOR DIFFERENCE IN THE HEAT IN OUR HOME. I WOULD DEFINATLY BUY THIS AGAIN!

Good Thing Don't Last
I have used this pump in my hot water baseboard boiler for the last 20 years. It performs well, but for every 5 years or so, the pump got noisy and I have to replace it. Usually the motors were fine. I think it is the bearings that were making the noise. They have replacement cartridge, but since it costs about half the price of a new pump, I ended up replace the whole thing to avoid trouble. I wish it is more durable.

I would buy this prodsuct again
Bought it to replace a circulator pump in an apt. complex. Taco is a great pump to use because of its small size compared to other pump manufacturers.

0011 circ pump
If you’re using a 1/24 HP , believe me this is going to save the amount of oil you’re burning! It’s much more efficient!

Great pump
The pump is working great. The only issue was it took 5 days for me to get a tracking number and another 3 days to reach me. It was pretty cold during the waiting period for my customer. I ordered it on Thursday 1/10/2025 and received it on Friday 1/17/2025.

AMAZING!
I have an outdoor wood boiler, used grundfos 1/6 hp pumps for years, never failed every 2 years I had to replace it. Decided to give Taco a try... That was 5 years ago, same pump, still running as good as the day I installed it. The damper door even stuck open a full 12 hrs boiling the water, didn't phase this little pump, still going strong. I will never buy anything but Taco again. The one I just bought is a back up, didn't even need it. Taco definitely builds top quality pumps. They just go and go.... Definitely 5* and then some! Take it from 20 years of wood burner experience Taco is the brand you want to go with.
