Tankless Water Heater Installation on the Mississippi Gulf Coast
Tankless water heater installation and replacement — gas and electric, whole-home and point-of-use.
About This Service
Tankless Water Heater Installation from Prestige Plumbing LLC
Tankless water heaters deliver hot water on demand and free up space. We size the unit to your household, handle gas line, venting, and electrical requirements, and install it to code so it performs the way it should.
A tankless water heater heats water only when you need it, so you are not paying to keep a 50-gallon tank hot around the clock — and you get back the floor space the tank used. Getting those benefits depends on the installation: the unit has to be sized to your household, and gas supply, venting, and electrical service have to meet the manufacturer's requirements.
We install whole-home and point-of-use tankless units for homeowners and businesses across the Gulf Coast, including first-time conversions from a tank heater and replacements of older tankless units.

Common Questions
Frequently Asked Questions
- Is a tankless water heater worth it?
- For many households, yes. Tankless units provide continuous hot water, use less energy because they are not reheating a stored tank, and typically last longer than tank heaters. The upfront cost is higher, especially on a first-time conversion, so we will walk you through whether the long-term savings make sense for your home.
- What size tankless water heater do I need?
- Tankless units are sized by flow rate — how many fixtures you run at the same time — rather than by gallons. A home with two showers running at once needs a larger unit than a small household. We look at your fixtures and usage before recommending a model.
- Can I switch from a tank water heater to tankless?
- Usually, yes. Conversions often require a larger gas line, new venting, or electrical work depending on the unit. We assess what your home already has and explain exactly what the conversion involves before you commit.
- Do tankless water heaters need maintenance?
- Yes. Most manufacturers recommend flushing the heat exchanger periodically to remove mineral buildup, which keeps the unit efficient and protects the warranty. We install isolation valves so that service is quick.
- How long does a tankless installation take?
- A straight replacement of an existing tankless unit can often be done in a few hours. A first-time conversion from a tank heater takes longer because of gas, venting, or electrical changes. We will give you a realistic timeframe after we see the site.
