Here is a previous similar question with answer - plus another "most popular question" with 130 some responses to the question of what a water heater replacement costs. For your area around $1000 plus or minus a couple hundred would probably be normal cost for a standard efficiency unit in your area.

Bear in mind almost all responses assume replacing with same fuel type - gas for gas, electric for electric - changing fuel type can run a couple hundred to $1000+ more depending on the issues getting the fuel/power service to it.

Putting an expansion tank and/or backflow preventer on it if now required by code and you do not have those can easily add another $250-500 range.

Note, if you have gas or oil now and are going to a high-efficiency (direct vent with or without built-in heat pump on top) unit, you will need electric power run to it which you may not have available therenow - that can run several hjudnred to $500 or more additional depending on distance to breaker box and whether box has capacity for a new circuit (should be a dedicated circuit), etc. At least some electric units with heat pump on top also need a separate power run to the heat pump, so that might influence your unit selection.

Also, if going with a new high-efficiency direct-vent (straight outdoors) unit, sometimes (relativley rarely) if the previous standard "gravity vent" oil/gas unit vented into a common exhaust flue with the house heating boiler or furnace, the flue will now be oversized for the furnace/boiler alone, so that can add $500 on up to the cost for resizing the flue. Not real common but happens, and can sometimes make the difference in whether going with a high-efficiency water heater is economically beneficial.

Note also - unless this is basically a one-bedroom house or is your "forever" home for only about 2 people, 30 gallons is pretty small these days, and could potentially affect resale if that is possibly in the works down the road. 40 gallon is more common for a normal 2-3 bedroom, and for a larger house or one with teenagers 50-60 gallon is now more the norm.

The cost difference between a 30 and up to a 50 gallon, for instance, is usually about $100-125 per 10 gallon size increment for the most common brands, so upsizing to provide greater capacity, especially if you currently have to avoid doing clothes wash or dishwasher and showering at the same time or have to wait for recharge after a shower or bath that might be a consideration.
