Hey guys,
I'm working on an addition and need to relocate the gas meter and have the house repiped to accommodate the larger load. I wanted to see what you all thought about which location is going to make more sense since I need to set this up with the gas co. soon.
I want to include a NG. backup generator since I have a sewer pump that needs to keep running when the power goes out. At max output, that load is 250k btu/h. The rest of the loads in the house total 480k btu/h, about half of which is a tankless. I am including all possible fixtures I'd like to have installed since the gas company needs that for sizing the meter even if a few don't end up happening.
My initial reaction was to locate the meter at the front center of the house (shown option A) since it is close to many of the fixtures. Using longest length method, I figure I need to have a 2" main installed up the wall, through the attic, and into the mechanical room. There the furnace, fireplace, outdoor, range drop off leaving 1-1/2 to the garage. Once the tankless is taken off, that leaves 1-1/4 running to the generator on the right side of the house.
Another option is to locate the meter at the left side of the house next to the backup generator. That makes the generator very easy. Since there's "only" 480k running into the house, I only need 1-1/2 to reach the mechanical room and drop off from there.
The second option is more piping, but smaller piping. It also requires that the main line into the house go through either the crawl space or the attic. The attic is easier to work in, but a harsher (temperature) environment. Crawl is somewhat cramped, but more temperature stable. Also requires drilling the foundation in two places and the main pipe entering just a few inches above grade. Of course one hopes never to have a leak in a gas piping system, but if one did ever develop over the years, it seems the crawl would show it quicker since most of the breathing air from the house comes from the crawl. I'm probably over thinking this...
Thoughts?
