What if any, are the drawbacks to using tankless water heaters over conventional gas water heaters? I'm currently converting my household appliances to natural gas, 1 by 1. What are some other brands besides Bosch & Takagi?
I am no expert, but the ones I've used (at a beach cabin, weekends only) had quite a low flow of water. The hotter you want it the less flow you have to get it to heat up. I know they are popular in parts of Europe
