Service Details

At Plunger Pros, we install tankless water heaters the right way from the start. As a local plumbing company based in New Braunfels and serving the greater San Antonio area, we help homeowners upgrade to a more efficient hot water system with honest advice, skilled workmanship, and personal service. That is what we mean when we say, Plumbing Done The Proper Way.

A tankless water heater, also called an on-demand water heater, heats water only when you need it. Unlike a traditional tank unit that stores and reheats gallons of water all day, a tankless system turns on when a faucet, shower, dishwasher, or washing machine calls for hot water. This can improve energy efficiency, save space, and give your home a more modern hot water setup.

What tankless water heater installation includes

Our installation service is built around safety, performance, and long-term reliability. We do more than swap out equipment. We look at the whole plumbing and utility setup so your new system works as it should.

  • Assessment of your home’s hot water demand
  • Guidance on choosing the right size and model
  • Removal of the old water heater if needed
  • Installation of the new tankless unit
  • Water line connections and shutoff review
  • Gas line sizing review for gas tankless models
  • Venting review and vent installation when required
  • Electrical connection coordination and code considerations
  • Temperature and pressure setting checks
  • System startup, testing, and performance verification
  • Walkthrough so you know how your new system works

How we help you choose the right system

Not every tankless water heater is the same. The right unit depends on how much hot water your household uses at one time. We look at things like the number of bathrooms, family size, incoming groundwater temperature, and whether you run multiple fixtures at once. A unit that is too small may struggle to keep up. A unit that is too large can lead to unnecessary cost.

We help you understand key sizing factors such as:

  • Flow rate measured in gallons per minute (GPM)
  • Temperature rise based on the difference between incoming cold water and desired hot water
  • Fuel type such as natural gas or electric
  • Installation location and venting requirements
  • Household usage patterns during peak demand

Our goal is simple: recommend a tankless water heater that gives you steady hot water and dependable performance without overselling you.

Gas and electric tankless water heater installation

We install both gas tankless water heaters and electric tankless water heaters, depending on the home and the customer’s needs. Gas models are often a strong fit for homes with higher hot water demand because they can deliver a higher flow rate. Electric models may work well in certain applications where gas is not available or where point-of-use heating makes sense.

For gas tankless installation, proper gas supply and venting are critical. Many homes need a gas line review because tankless units often require more BTU capacity than a standard tank water heater. We check these details carefully because safe operation matters.

For electric tankless installation, we review electrical capacity and unit requirements. These systems may need dedicated circuits and enough service capacity to support the heater. We make sure the installation plan is clear so there are no surprises.

Benefits of installing a tankless water heater

Many homeowners choose tankless systems for a mix of comfort, efficiency, and convenience. While every home is different, common benefits include:

  • Hot water on demand for daily use
  • Improved energy efficiency compared to many traditional storage tank systems
  • Space-saving design with a compact wall-mounted unit
  • Long service life with proper maintenance
  • Reduced standby heat loss since water is not stored in a large tank
  • Clean, updated plumbing setup that can add value and convenience

If you are tired of running out of hot water or you want to replace an aging water heater with a more efficient option, a tankless upgrade may be the right move.

When tankless installation makes sense

We often recommend taking a closer look at tankless water heater installation when:

  • Your current water heater is nearing the end of its life
  • You are remodeling a kitchen, bathroom, or utility space
  • You want better energy efficiency
  • You need to free up room in a garage, closet, or mechanical area
  • Your household wants more reliable hot water during busy times
  • You are building a new home and want a modern water heating solution

If your current unit is leaking, rusty, inconsistent, or making noise, it is a good time to talk through replacement options before you lose hot water completely.

Our installation process

We keep the process clear and straightforward. First, we inspect your current setup and talk through your hot water needs. Then we explain your options, answer your questions, and provide a clear recommendation. Once the plan is approved, we complete the installation with attention to detail and test the system to make sure everything is operating safely and efficiently.

Before we leave, we show you how the new tankless water heater works, what basic maintenance it needs, and what signs to watch for over time. We want you to feel confident in your investment.

Important installation considerations

Tankless water heater installation is not just about hanging a unit on the wall. There are several details that matter for performance and code compliance:

  • Correct sizing for your home’s peak hot water demand
  • Proper gas pipe sizing for gas-fired units
  • Approved vent materials and vent routing where required
  • Safe condensate handling on high-efficiency models
  • Water quality concerns, especially in hard water areas
  • Isolation valves for future service and flushing
  • Adequate clearances and manufacturer specifications
  • Reliable shutoff access and leak testing

In our area, hard water can affect plumbing fixtures and water heating equipment over time. We take that into account and can explain how maintenance and water quality impact tankless system life and performance.

Tankless maintenance after installation

Like any plumbing system, tankless water heaters need routine care. Regular maintenance helps protect efficiency, support consistent performance, and reduce mineral buildup inside the heat exchanger. We educate customers on the importance of periodic flushing, especially in Central Texas where hard water is common.

We believe the best installation is one that keeps working well long after the job is done. That is part of our promise of Plumbing Done The Proper Way.

  • How do I know if a tankless water heater is right for my home?

    A tankless water heater is a great fit for many homes, especially if you want steady hot water, a space-saving setup, and a newer water heating system.

  • Will a tankless water heater give me enough hot water for showers, laundry, and dishes at the same time?

    Yes, when the unit is sized correctly. This is one of the biggest reasons professional installation matters.
