A tankless water heater can be a great option for the right home, but it is not something you want guessed at or rushed. The size of the home, number of fixtures, gas supply, venting, water quality, and installation location all matter.

At Shanks Onsite Services, we take the time to look at your setup and talk through what you are hoping to improve. Some homeowners want more dependable hot water. Some are replacing a failing tankless unit. Others are interested in freeing up space or upgrading from a traditional tank water heater.

Our goal is simple: help you feel informed, comfortable, and confident before moving forward.

Tankless Water Heater Installation

If you are considering a new tankless water heater, Tommy can look at your home’s plumbing and gas setup to help determine whether tankless is a good fit. We can explain what would need to be done, what to expect during installation, and what type of system may make sense for your household.

Tankless Water Heater Replacement

If your current tankless water heater is older, unreliable, giving error codes, or only providing hot water to part of the home, replacement may be the best long-term option. Tommy can review your current setup and explain whether replacing the unit makes more sense than continuing to chase repairs.

Navien Tankless Options

We often discuss Navien tankless options when they are a good fit for the home. Navien systems are a popular choice for homeowners looking for a modern tankless water heater setup. Tommy can walk you through whether a Navien tankless system makes sense for your plumbing, gas, venting, and hot water needs.

Gas Tankless Water Heaters

Gas tankless systems need proper planning. The gas supply, venting, water lines, condensate, shutoff valves, and installation space all need to be considered. We take installation details seriously because they affect both performance and long-term reliability.

You may want to talk with us about replacement if you are noticing:

• Hot water only working in part of the home

• Water turning cold during use

• Repeated error codes

• The unit needing frequent resets

• Repairs becoming more expensive

• An older tankless unit that is no longer dependable

• Changes in hot water demand in the home

• Concerns about an existing installation

Not every tankless issue automatically means replacement. Sometimes there may be a repair or maintenance option. But when the unit is older, unreliable, or not serving the home well, replacement can be the more practical choice.

When Tommy looks at your tankless water heater, he can help you consider:

• The age and condition of the current unit

• Whether parts or repairs are realistic

• Whether the current setup was installed properly

• Whether the unit is the right size for the home

• Whether a replacement would solve the actual problem

• What installation would involve

• What your options are before moving forward

We would rather explain the situation clearly than give a rushed answer.

During a tankless water heater estimate, Tommy may look at:

• Your current water heater setup

• Gas line access and sizing considerations

• Venting location and requirements

• Hot and cold water line layout

• Condensate drain options

• Available wall space

• Access for future service

• Your household’s hot water needs

• Any concerns you have been noticing

After looking everything over, we can explain what would be involved and provide a clear estimate before work is done.
