It depends on the size, fuel type and any venting or code updates your home needs. Ethical Plumbing gives you a written price for each option before work starts, and most tank replacements are finished in a few hours. Call 864-438-0525 or book online.
Replacing a water heater is not just swapping one tank for another. The new unit has to match how your household uses hot water, fit the space, and meet the code that has changed since your old heater went in.
We start by asking how many people live in the home, how many bathrooms you have and whether you run out of hot water today. From there we recommend a size and type, and explain the trade-offs. If tankless makes sense for your home, we show you that option and its price next to a tank.
On install day we protect the floors, remove the old heater, set the new one, and connect water, gas or power and venting. Then we fill it, test the relief valve, check for leaks and walk you through the controls before we leave.
A few of these on a heater over about 10 years old usually means replacement will cost less than repeated repairs.

Fast recovery and lower running cost where natural gas is available. A straight swap is usually the quickest install.
Simple to install where there is no gas line. A good fit for smaller households.
Endless hot water, a smaller footprint and a longer life, with a higher up-front cost.
Uses far less electricity than a standard electric tank. Needs space and airflow around it.
Codes change, and an older heater was often installed under rules that no longer apply. A proper replacement brings the installation up to date:

They exchanged our old water heat tank with a tankless water heater and repiped the crawl space. Ivan and Asher did the whole work within less than two days. We felt treated with respect, everything was explained well and they left everything clean.
Brendan came out same day to service our hot water heater. We have hot water now! They were friendly, honest, and we paid a fair price. If (when) we have plumbing needs in the future we will def give them a call.

A straight replacement of a tank heater usually takes a few hours. Moving the heater, changing fuel type or switching to tankless can take most of a day.
Two or three people usually do well with 40 to 50 gallons. Larger households often need 50 to 75 gallons or a tankless unit. We size it to your household and the fixtures you use at the same time.
Tankless makes sense if you run out of hot water, want to free up space, or plan to stay in the home for years. It costs more up front and may need gas line or venting changes. We price both so you can compare.
If your home has a pressure reducing valve or a backflow device on the main line, the water system is closed and an expansion tank is usually required. We check this on every install.
We disconnect and remove it as part of the replacement, so you are not left with a tank in the garage.
Yes. Attic and upstairs heaters need a drain pan piped to a safe spot, and we recommend a leak sensor so a slow leak does not come through the ceiling.
Yes. Financing is available through GoodLeap on water heater replacement, and VIP Prevention Plan members get 0% financing options.
Yes. They need more space and airflow than a standard tank, so we check the location first and tell you if it is a good fit.
