Re: [RE-wrenches] tankless hot water and pumping question

[Todd Cory]

Title: Message

Thanks for the recommendation. Does this unit need an external pressure switch or is that integral? Does these work w/o an expansion tank or will they cycle on/off excessively set up in a direct pumping situation?

About 2 gpm at pressure. Not freeze-tolerant. Allan
