How long does a water heater replacement take?
A straight swap of a tank water heater usually takes a few hours once we are on site. Switching from a tank to a tankless water heater takes longer, often most of a day, because it can need new gas piping, venting and a condensate drain.
Tank or tankless?
| Tank | Tankless | |
|---|---|---|
| Brand we install | Bradford White | Navien |
| Typical lifespan | About 8 to 12 years | Often 15 to 20 years with regular flushing |
| Hot water | Stored in the tank, so it can run out | Heated on demand, so it does not run out when sized right |
| Space | Takes floor space | Mounts on the wall |
| Upfront cost | Lower | Higher |
| Install time | Usually a few hours | Often most of a day when converting |
We tell you on site which makes more sense for your home and how you use hot water.
What size water heater do I need?
- 1 to 2 people: 40-gallon tank
- 3 to 4 people: 50-gallon tank
- 5 or more people, or a big soaking tub: 75 to 80-gallon tank, or a tankless unit
Tankless water heaters are sized by flow rate and by how cold the incoming water gets in an Indiana winter, not by gallons.

How long does a water heater replacement take?
A straight swap of a tank water heater usually takes a few hours once we are on site. Switching from a tank to a tankless water heater takes longer, often most of a day, because it can need new gas piping, venting and a condensate drain.
Should I switch to a tankless water heater?
Tankless is a good fit if you run out of hot water, want to free up floor space or plan to stay in the home a long time. A tank water heater costs less up front and is the quickest replacement. We explain both options on site.
What size water heater do I need?
As a rule of thumb, a 40-gallon tank suits 1 to 2 people, a 50-gallon tank suits 3 to 4 people, and larger households or big soaking tubs need a 75 to 80-gallon tank or a tankless unit. Tankless units are sized by flow rate and how cold the incoming water gets in winter.
How much does water heater replacement cost?
It depends on tank or tankless, size, gas or electric, venting and any code updates the install needs. We give you options and an upfront price on site before any work starts, and we will beat a comparable written estimate from another licensed plumber by 10%.
