Question
Is it worth it to pay for a Phoenix water heater or buy a condensing tankless water heater?
We are considering getting a new water heater. In my internet research, I came across Phoenix water heaters and it seems like they are quite efficient. However, I have been told they are very expensive (cannot figure out how much they are, though). Thus, is it worth it to spend money on this or get a condensing tankless unit? I am all for tankless ones but it seems like there aren't too many plumbers doing this job in Allentown. Then, there is the option of getting solar thermal, but I think their prices really should come down before people can afford them.
Answer
If you continue to have difficulty finding a green plumbing pro that can install a tankless unit, or a reasonable price for the Phoenix heater, reconsider the solar thermal option.
In addition to a full 30% federal tax credit on labor and materials (with no max), Pennsylvania offers incentives as well.
The DSIRE website has more info on PA's state incentives here.
