Here is a link to that question with well over 100 responses - these days while it is sometimes seen with simple installs, generally the $1000 range is a common installed cost for normal sized (40-55 gallon) conventional tank-type water heaters.

Tankless heaters cost WAYYYY more if you want that - just be sure to research the brand and tankless heaters in general, because an awful lot of people are disappointed in their throughput capacity and issues with lime or iron buildup in them, plus many providers are charging obscene prices because people do not know what they should really cost.

Also, pretty much any tank-type water heater over 55 gallons has to be direct-vent - requires exhaust modification so it vents through nearby wall through plastic pipe rather than rooftop vent (though some models can run the new piping up the existing exhaust flue if a flue dedicated to that device). Can get complex, because sometimes combined water heater and furnace/boiler flue, which with a direct-vent device will now have less exhaust gas going through it, ends up being too large for just the furnace or boiler so has to be downsized to meet code.

Also, to meet the new energy criteria for larger units, water heaters over 55 gallons pretty much have to have a heat pump mounted on top of them, which drives their installed cost up into the $2000 ballpark in many cases - also requires new wiring to it if you have a gas water heater, costs a LOT more to repair, and in many cases the supposed greater heat pump efficiency is a downright lie because it is stealing heat from the house to heat the water, which the furnace then has to make up. My recommendation - avoid a heat pump equipped tank type water heater if possible - if you need a larger hot water capacity you can commonly get it with a commercial 55 gallon water heater with higher recovery rate (so burns fuel at a higher rate) - generally a lot cheaper to buy, install, and maintain.
