Hi, I was interested in any comments on the pros and cons of a gas versus electric tankless water heater. Is one better than the other? Which performs better and/or is more cost effective? Or, are the equally good in quality, performance and cost? I live in the Austin, Texas area and have heard the gas tankless water heaters are preferrable, but don't have specifics as to why. Any recommended brands? Any approximate cost on the installation? I'm just looking for an approximation, so if the installation say was $1,500, but someone wants to charge $5K then I'll know it is way off base. Thanks.
