-
- The tankless heaters simply heat the water in real time using a LARGE
- burner and a heat exchanger. The one I used, the Paloma, has a
- 90,000 btu input burner and a small heat exchange above it that looks
- like the heater core out of a car. There is a proportioning valve
- that meters gas according to the water flow and temperature in order
- to maintain the setpoint temperature. There are also a couple of
- safety systems that turn the gas off if water pressure is low or
- the flue gets too hot.
-
- I used to own a welding supply company where we also sold propane and
- gas powered appliances. I looked around and determined that the
- Paloma was the best heater and thus that was the one we sold. It is
- a small package, about the size of a 2 year old kid :-) It bolts to
- the wall at a convenient place. It connects just like a regular
- heater except it needs a larger gas line and flue. I used an old
- wood stove flue in my fireplace. In my cabin I installed a thru-wall
- vent that vents horizontally. The flue remains cool enough to rest
- your hand on.
-
- These things are rated in terms of how much water can be heated
- to what degree of temperature rise. Mine is rated at about 3.5 gpm
- at 100 degree rise. The next larger one is about 120,000 btu
- input and can do about 5 gpm at 100 degree rise as I recall.
-
- If I had it to do over, I'd install the 120,000 btu. When the inlet
- water temperature is near freezing in the winter and so not much
- cold is used to dilute it in the shower, the flow is marginal for
- my large shower head. If you used a low flow head, you could run
- two showers or a shower and the washer at the same time on the larger
- heater.
