I am replacing my 80 gal electric tank system with a tankless system. After reading up about some of the down sides of a tankless system - cold water for up to a minute - I decided to hook up the system with a small tank (5 gals).

The idea is to take the output of the tankless system and feed it into the cold inlet of the tank. I will take the output of the tank and use it the normal way - feed my hotwater line. Does this make any sense?

Thanks in advance,

Chuck

Wegrzyn - Hi, I'm not a plumber but your idea seems to make sense. I'm assuming (that dangerous word!) the 5-gal tank is either heated in some way or super-efficient in holding its heat. Also, I'm assuming the hot water lines are insulated nearly all the way from the tank to each hot water outlet. Otherwise, you'll still have some cold water at the hot water outlets when you first turn it on. Other posters who have experience in this area will hopefully post other guidance/advice for you. Good luck - regards! Jim D/West Point, VA

Better to get a 25 or 30 gallon booster tank with this system. You'll have more hot water. It will be heating during non use periods with the circulator & tankless. These are great systems I recomened it. C.

Whether you had a tank or a tankless there is a period of cold water before the hot reaches the fixtures. I have been puting in a small 110 volt 2 1/2 gallon heater at the end fixtures and running the hot water line into it.

Other plumbers have been criticizing this method because it would seem that you would still get a period of cold water in a couple of minutes. I have only put in about ten of these systems before I stopped to rethink but I am not getting a significant temperature drop after the 2 1/2 galons of hot are gone and the system is evacuating the cold water from the house heater to the cabinet heater.

Do it. None of the customers have had criticisms but there must be some reason others are not doing this.

It seemed to make sense to me. Have you ever used an electrical tankless system instead of the gas ones?

I have only installed the gas ones and am only certified on the Renaai's.
