I have the wonderful task of replacing our 50gal NG hot water heater for spring break. I know there are some plumbers and others on here that have made the conversion but I am considering going tankless. Experiences, thoughts, recommendations? We currently have a recirculating pump and I've noticed there are a few tankless models that also offer that feature. I'd like to keep this feature and would probably stay tanked rather than going tankless if I had to do without a recirculating pump.
