I see a lot of options and i do not know which one to get. I narrowed it down to a 50gal. Are some better than others?
Side note: I purchased a vandelized home and the boiler and 50gal indirect water heater was left behind but all piping was stolen. I got new boiler but debating whether or not to use this water heater. It has been sitting with cut open pipes for atleast 2 years. Home was built in 2000 so it may be 13 years old, not sure when it was purchased. What are your thoughts on it possibly being outdated and needing to be cleaned, how to clean if worth keeping? Would it be less efficient cause it may be old? Also what is your recommendation for new? Thanks
