hot water on demand systems ??/

[JaySimon]

What I dont like .the wasted water at the start to get the hot water, but once its hot its there .

A re-circ line fixes this issue. I would have to agree though, hard to see good water used for nothin...

On demand definately the way to go, I have a Rinnai that also feeds my heatlink pannel for the garage and house slabs, no problems, fyi hooked up the heatlink system for approx 3600.00, Rinnai was about 2300.00 installed.

I have a Rinnai as well. I like the endless hot water, at first I was having issues with the amount of water wasted ( we are on a cistern and get water trucked in) then I put a re-circ pump on and this lowered the wasted water significantly. I will say this though, they are F-IN Expensive to repair!! 2 Heat exchangers in 2 years ( freezing issues before I put the re-circ pump in...long story). Ever since I put the re-circ pump in - no issues.

want to go this route for our cabin. With only one bathroom and kitchen and drawing from a cistern at 60'F., would an electric be okay?
Alternately two 120 vac in series?

Bought a Aqua NG Tankless Hot Water Heater 10 L, 2.65 GPM off of E-bay paid $180.00 landed.....to use in our shop so not much demand at all.....the heater is only about 10' from the sink but it takes a while to get hot water to the sink and it sure coundnt handle much more than one sink. Not sure if it's the brand or the size....but atleast theres no more pilot light running 24/7 for the odd time we use the shop sink...

I have a problem, plumber still working on it so any sugestions would be of help, with my Rinnai. when in the shower and someone turns on a tap somewhere else, hot or cold, the water goes instantly cold. It did not do this till the Rinnai was put in. Any sugestions?
