I discovered two problems that are related to the heater operation......heater works great, but low water pressure will affect operation. Purchased a Grundfos pump at Home Depot (did not install yet).

Also discovered that the gas (propane) supply line that they hooked up to the heater is 1/2". Needs to be 3/4" for proper operation.

I have the parts and will do the install on my next trip down in a month or so.

tank-less water heater are good if you are in your house on weekends with 20 people and then nobody again all week. i know that the ecoyeco guys in TJ sell tank less for $200.00 that work with high pressure. They are nice so ask them if you can buy one to try on your low pressure system.

I suggest that if you are at your house all year you should have
solar water heater
no more gas. no more elect. And plenty of hot water all year around.

I agree. It seems like a few people have good luck with the on demand heaters, but many have problems. After reading all the complaints about them on this board, and not wanting to waste propane on an traditional water heater, we wound up buying this solar water heater: Link It's not installed yet so I can't really say how well it works, but if it operates as advertised, we'll only need to use propane to supplement heating the water on very cloudy days.

I have found that one of the keys to a tankless system is pressure. You need to have enough of it as well as not a lot of fluctuation in the pressure. A friend of mine has a tankless system in San Quintin that was supplied from a pressure tank fed from his pila. The pressure fluctuations from his pressurized tank would kick off the tankless flames for some reason. We installed a 2500 liter water tank on top of his house and with a constant pressure on the supply side his problem was solved.

Also needs a 3/4" gas (LP/Natural) supply line to the water heater to ensure the burner is operating at optimum performance

Yes, that is a good point as well. These units tend to gobble up gas on higher flow demands and as your LP is relatively low pressure in the line you need more flow volume on the supply side.

Saving Gas


Awhile back, I thought my Mexican 10 Gallon LP water heater had reached its end-run when the pilot would go out after heating the water. Since it still worked otherwise and kept the water hot enough all day, I kept relighting it each evening while I thought about taking the burner apart or just replacing it. After awhile, I just got used to it and found I saved a LOT of Propane.

For better or worse, the problem cleared itself and it now stays lit again.

Don't know if I'm Better or Worse off.
