      What are the advantages or disadvantages of a hot water heater over gas? How much more expensive are they to operate? What special wiring or installation is required? Different types?

      It all depends on your local utility costs per therm
      1- Gas can explode and the fumes can kill you

      2-Electric is clean energy BUt more expensive generally

      3- Electric heaters can be had in 110-440 Volts

      4- Gas can have various inputs as natural “gas” can have a low of 900 BTU’s per CU FT and a high of 1,200 BTU’s per cu ft. You have to contact your local supplier to find out your heating value. Also your height above sea level has a lot to do with gas heating Less oxygen less efficency.

      5- Electric heater require no venting

      6- In case of a black out you lose H/W not so with gas heaters.

      7- To find the actual cost to operate contact your local utility

      8-The “gas unit” requires more service as far as cleaning goes (flue and burners)

      9- Electric heaters require a dedicated circuit BUT a water heater can go off a 3/4″ branch line DEPENDING on developed lenth and BTU input.

      Both heaters depend on the watts/btu input for recovery rate
