Re: Install tankless water heater--DIY project?

I put in a Bosch 117000 btu Ng, And yes it takes 34-35f incomming and
makes a hot shower not even being set to high. You will need to buy a
Manometer? to measure gas flow. Tankless are big gas Btu users, to get
its potential you need to know supply is adequate with all other
apliances competing and run the proper size pipes. Other than that you
can do it, I recomend a Flush - freeze drain set up at the bottom and
top so you can DeLime it by pouring through something like lime away and
quick draining for freeze protection. Follow instructions that came with
the unit. A fire resistant wall board-aluminum sheet, is a good saftey
precaution. I used a stainless wall vent and removed siding around it
since exuast is real hot. Get the unit with remote thermostat. I save
75% over my old super insulated Electric tank with my Bosch with Battery
ignition. Insulate hot supplies with foam pipe insulation. I kept my old
tank inline with Bypass valves, stripped its insulation, now it tempers
cold incomming water to save even more.

Tanks are for dinosaurs, sears best Ng tank has an energy factor in the
60S, Tankless evergy factors are up from 83 to 90+. considering 1/3
yearly Ng usage can be to heat water people need to learn.
