We are considering adding a 54,000btu gas cooktop, 22,000btu dryer and a 50,000btu BBQ grill to our existing system. We currently have a 70,000btu boiler and a 199,000btu tankless HWH; for a total of 395,000 btu.
There currently is a 250 cfh meter and 1" supply into the house.
The cooktop will be the furthest appliance, at approximately 70' from the meter.
We've received two estimates/proposals. The first wants to tee off the existing 1" line and running 3/4 to supply the three new appliances.
Number two told us our current meter is too small as well as the 1" supply. He says we need to increase supply to 1.25" to the boiler and HWH, with the rest of the piping following "longest run method" and upgrade meter to 400 cfh.
Now my question: is the meter sized to max btu load? What is the likelihood of max load happening?
Thanks...
