How many tankless gas water heater will plumber need.
Please just the answer to my questions. Please no video of the bear telling me I am a idiot for wanting to sell or install tankless gas water heaters. There is a market for tankless gas water heaters and tank type gas water heaters
House will have seven (7) showers with 2.5 GPM shower heads. No tubs. Kitchen sink, 7 lava faucets, dishwasher, washing machine.
Well water 50 F degrees incoming 70 F temp rise to 120 F degrees.
I told the contractor to check how many GPM the well pump will produce.
How many 199,000 TGWH will be needed?
I say reduce all shower heads to 1.5 GPM and I would install two (2) 199,000 BTU TGWH and I should get about 9.5 GPM max at a 70 F degree rise.
