re: Tankless hot water heaters?

One correction. The plumber doesn't have to install an orifice at the meter. He needs to make sure the pipe running to the heater is large enough to handle the volume of gas needed for it to operate properly. That may be the problem in your house. Your pipes aren't large enough for you to run your heating system, water heater, and any other appliances you have at the same time. That would be why you don't notice it during the summer.

Thats why I don't have one currently. I rented a house that had one and it was oustanding. Bought our current house and was looking to add it.
Would have to either install a 1 inch gas supply line across the width my house from the gas supply to the water heater (and possibly redo the intake/meter area as well) or change how the piping works in my house (attic area). Either way, a sizeable investment (once you add in the heater) that just wasn't worth it at the time.
I'll be redoing one of the bathrooms in the next 3 or so years, and may look at it then.

Correct, his regulator is going to be good for 800,000 - 1,000,000 btu.
A 3/4 gas line is needed otherwise if the heater reaches full demand and doesn't have sufficient gas supply the heater will throw an error code.
The output temp is regulated on the motherboard chip that regulates temps and flow. If output temps arent constant then the heater needs service.

Who ever does the orifice install...I wasnt sure. But its not what is inside my house I dont believe. It only happened once a couple years ago and the last 2 mornings when it was real cold. Nothing else in the house running...no heater...no appliances...just one hot water location and nothing. Error code 11 which points to not enough pressure. It only happens from like 6-730 the last 2 mornings. Thats when a lot of people are up taking showers and warming there house so the gas pressure on that grid drops. Thats what I was told last time when I called the manufacture to come out and check. They did some testing and that is what they found. They replaced the orifice (or whoever did) and it was ok but there are more houses now so it may have dropped again.
