Thank-less water heater

I was recently conducting an audit on a home when I ran across this perplexing situation, a tank-less water heater that someone installed with a reticulation pump set on a timer to run 3 hours in the morning and 4 hours in the evening. I guess the contractor has not heard of the on demand system where the homeowner can call for hot water by pushing a button and waiting a minute before turning on the water.At least it had a temperature sensor to shut off the circulation pump once the hot water…See More

"I've done the tankless with chillipepper on-demand pump, wireless controls, light switch in bathroom triggers the pump to run -- IF NEEDED.  Cost of pump $180,  cost of wireless controls $100.  That is a small amount compared to…"

"Actually I could care less what climate they are in - conserving water is always good & dare I say trumps energy savings I gave two options where they didn't have to - maybe you should quit firing away & slow down a bit I am not saying…"

"Sean,  That this system is outdoors indicates a climate that may have water conservation issues.  That may not have crossed your radar.  The awareness of the occupants regarding both water conservation and energy conservation must go…"

"Seriously Ted?  As for the switch - try it is already included with many & up to maybe $20 worth of parts for a vacuum based system - less for a low voltage. Math is pretty simple - QUAT & yes the numbers will vary based on…"

"I would check the Noritz installation manual. Most often whenever a recirc pump is installed on a tankless an expansion tank is also required to protect the tankless and the manufacturer warranty."

"Ok, so we are then on the same page then - we both have issues with the timer setup, but not the "on demand" part which does require a recirculating pump (whether by the heater, under a sink, etc...) - Heads up, you got to be…"

"Hi Sean, I am glad you asked, The whole idea of installing a tank-less (on demand) water heater is that it only runs on demand ie. when the occupants of the home are calling for hot water. installing a recirculating system that operates on a…"

"Looks like a nice install to me. Looks like they went to serious lengths to insulate the line, so how much less loss do you think your button trick would accomplish?  There is a pretty steep chance this is a customer preference item, not a…"
