Pump used to circulate hot water

[shawnee]

Hi I am looking for a small affordable pump that can circulate 60-70C water from a hot water bath through a 12'' long humidifier tube and then back to the water bath. Does anyone have any suggestions for a pump that can do the job? thanks so much!

See "circulator pump" and/or "hydronic systems".
Suitable pumps are produced commercially for circulating hot water through house radiators.

A key aspects are the system's working pressure and maximum fluid temperature.

TACO, it's what is in my hydronic heating system.

There are plenty of suitable pumps used in both hydronic heating and in domestic hot water recirculation systems. Some of the latter take as little as 12W.

If you are able to adjust the component locations, you might be able to start a thermosyphon; no pump required.

Several factors to think here.

Is this an open system?
Where in relation to the water level (if it is an open system) of the tub is the pump located?
What is the head loss of the system?
What kind of flow rate are you looking for?

My first thought would be a Taco or Goulds circulating pump. they're relatively inexpensive, but work well.

There are many different ways for pumping water, and unless knowing the conditions required for pumping, help is going to be difficult.
