Tankless Water Heater Installation & Repair

Drain State Plumbing

No hot water, changing water temperatures, or problems with an existing tankless system? Drain State provides tankless water heater repair, replacement and installation based on the condition of the unit and the property's existing setup.

Tankless Water Heater Service

A tankless water heater works differently from a traditional storage-tank system. Instead of keeping a tank of hot water ready, the unit heats water as it is needed. That also means the way a tankless system is diagnosed, repaired, and replaced can be different from a standard tank water heater.

Drain State provides tankless water heater installation and repair for properties dealing with hot water problems, unreliable performance, failed units, or plans to install a tankless system.

We start with what the system is actually doing and how it is installed before deciding whether the problem calls for repair, replacement, or a new installation.

01
Check How the Unit Is Behaving

No hot water, changing temperatures, reduced performance, or a unit that keeps shutting down can point to different problems.

02
Look at the Existing Installation

The unit, plumbing connections, available utilities, and installation conditions all matter when diagnosing or replacing a tankless system.

03
Repair or Replace Based on the Problem

A serviceable problem does not automatically require a new unit. Replacement becomes relevant when the condition of the system makes continued repair impractical.

Tankless Water Heater Problems We Help With

Tankless water heater problems can show up in several ways. The symptoms matter because a unit that produces no hot water at all may have a different problem from one that works intermittently or struggles only when hot water demand increases.

01

No Hot Water

If the unit does not produce hot water, the system needs to be checked to determine whether the problem involves the heater itself, its controls, available utilities, or another part of the installation.

02

Hot Water Temperature Changes

Water that repeatedly changes from hot to cool can be a sign that the system is not heating consistently or that another condition is affecting performance.

03

Unit Shuts Down or Stops Heating

A tankless unit that starts normally and then stops producing hot water deserves a closer look instead of simply resetting the system repeatedly.

04

Reduced Hot Water Performance

If the system used to handle normal hot water use but now struggles to keep up, the change in performance can help narrow down what should be checked.

05

Water Around the Unit

Water near a tankless heater should be traced to its source. A plumbing connection, valve, fitting, or internal problem can require different work.

06

Recurring Tankless Water Heater Problems

If the same problem returns after previous service, repeating the same repair without understanding why it failed again may not solve the underlying issue.

!
Tankless unit keeps shutting down?

Repeated resets may temporarily restore operation, but if the same problem keeps returning, the reason the unit is stopping needs to be identified.

How We Approach Tankless Water Heater Repair

We do not start by assuming that every tankless problem requires replacement. The first step is to understand the symptoms and the existing installation.

01
Start with what the system is doing

Check the Symptoms

We look at whether the unit produces no hot water, works intermittently, changes temperature, shuts down, leaks, or has another repeat problem.

02
Look beyond the symptom

Check the Unit and Installation

The heater itself is only part of the system. Plumbing connections, available utilities, and the way the unit is installed can also affect how it operates.

03
Repair what can be repaired

Address the Actual Problem

If the failure is limited to a repairable part of the system, service can be focused on that problem rather than replacing the entire unit.

04
Know when replacement makes more sense

Replace the Unit When Repair Is No Longer Practical

Replacement may need to be considered when the unit has repeated serious problems or another repair would not leave the system operating reliably.

Tankless Water Heater Repair vs. Replacement

A tankless water heater problem does not automatically mean the unit needs to be replaced. Some failures can be isolated to a repairable part or another condition affecting the system.

Replacement becomes more relevant when the unit continues to have serious problems, has a failure that does not make practical sense to repair, or can no longer provide reliable hot water.

The decision should come from the condition of the system and the cause of the problem, not simply from the fact that the unit stopped heating.

✓
Not sure whether the tankless unit can be repaired?

Start with the problem the system is actually having. Drain State can check the unit and existing setup before you decide whether replacement is necessary.

Tankless Water Heater Installation

Installing a tankless water heater is not always a direct replacement for a traditional tank system.

The installation depends on the unit being used, the property's existing plumbing, the available utilities, the location of the heater, and what changes are needed to support the new system.

That is especially important when a property is switching from a storage-tank heater to tankless. The old water heater may have been installed around a completely different set of requirements.

Replacing a Tank Water Heater With Tankless

Removing a tank water heater and putting a tankless unit in its place can involve more than changing the heater itself.

Before making the switch, the existing setup needs to be checked to see what can stay and what may need to change for the tankless unit being installed.

The goal is not to force a tankless heater into a location simply because the old tank was already there. The installation should work with the actual requirements of the new system.

If you are replacing a traditional tank heater with another tank-style unit, see our water heater installation and replacement service.

Tankless Water Heater Repair

A tankless system that has stopped working may still be repairable. The important part is determining what is actually preventing the unit from producing reliable hot water.

We pay attention to whether the problem happens all the time or only under certain conditions, whether the system shuts down, whether hot water temperature changes, and whether the problem has happened before.

For traditional tank water heater problems, see our water heater repair service.

New Tankless Water Heater Installation

A new tankless installation may be part of a renovation, replacement project, or a change to the property's existing hot water system.

When there is no existing tankless unit to replace, the installation needs to be planned around the location and the connections that will serve the new heater.

That can make a new installation different from replacing an existing tankless unit in the same location.

Choosing a Tankless Water Heater

A tankless water heater should be selected around how the property actually uses hot water. The unit needs to be able to serve the expected demand and work with the installation available at the property.

Choosing a unit simply because it has a larger capacity or more features does not automatically make it a better fit.

The existing plumbing and utilities should be considered before the unit is purchased or installed, especially when changing from a traditional tank system.

When a Tankless Water Heater Problem Is Urgent

A tankless heater that stops producing hot water is inconvenient, but an active water leak or another plumbing problem that is causing property damage requires faster attention.

Frequently Asked Questions About Tankless Water Heaters

Can a tankless water heater be repaired?

Yes, many tankless water heater problems can be repaired depending on the cause of the failure and the condition of the unit. Replacement is not automatically necessary simply because the system stops producing hot water.

Why does my tankless water heater keep shutting off?

A tankless unit can stop heating for different reasons. If the same problem keeps returning after the unit is reset, the cause should be checked rather than relying on repeated resets.

Why does my tankless water temperature keep changing?

Temperature changes can happen when the system is not heating consistently or another condition is affecting how the unit operates. The pattern of the problem helps determine where to start.

Can I replace a traditional water heater with a tankless system?

In many properties, switching from a tank system to tankless is possible, but it may not be a direct swap. The existing plumbing, utilities, installation location, and requirements of the new unit should be checked first.

Should I repair or replace my tankless water heater?

Repair may make sense when the problem is limited to something serviceable and the rest of the system remains reliable. Replacement becomes more relevant when the unit continues to have serious problems or another repair would not provide dependable service.

Do you install new tankless water heaters?

Yes. Drain State provides tankless water heater installation as well as replacement of existing tankless systems. The installation depends on the property and the requirements of the unit being installed.

Do you provide tankless water heater service in Philadelphia?
