We had a tricky and unusual situation, and Carl figured it out. He did a thorough analysis and did the repair efficiently. He communicated the problem and solution to us in understandable terms. Our problem has not recurred. Nice job, Carl, and thanks.
Contacted Haller due to flooding in our basement. Was able to get appointment the same day. Eliezer was very professional and quick to figure out the source of the flooding. Quoted us the cost and what is needed to be done. He quickly went to work and unclogged our pipe that was causing the problem. Would recommend Haller for their 24 hour on call service and Eliezer for doing a great job.

Tankless Water Heater Repair Services

Haller’s tankless water heater repair services are designed to quickly restore your hot water and keep your system running efficiently.

Our licensed plumbers diagnose issues accurately and complete the repairs that get your system back on track across Central and Eastern Pennsylvania.

If your system will not ignite or struggles to heat water, the issue is usually in the burner or ignition components. We repair or replace these parts to restore proper heating performance.

Central Pennsylvania water has enough mineral content that scale buildup is a common reason tankless systems lose efficiency or stop heating properly. Our team clears blockages and addresses buildup to improve system function.

Tankless systems often display error codes when something goes wrong. We quickly diagnose the cause and perform the necessary repairs to resolve the issue.

Leaks around fittings or internal components can impact performance and cause damage over time. We locate the source of the leak and make precise repairs to protect your system and home.

Tankless systems have specific venting requirements, and a venting issue can shut the system down or affect performance. We inspect and repair venting and combustion components to restore safe operation.


24/7 Emergency Tankless Water Heater Service

When Your System Goes Down, We Respond Around the Clock

A tankless system that fails on a cold morning or throws an error code in the middle of the night is not something that can wait until business hours. Haller’s licensed plumbers are available 24/7 for emergency tankless water heater service across Central and Eastern Pennsylvania, getting continuous hot water back in your home as quickly as possible.

Tankless Water Heater Replacement Services

Tankless water heaters are very reliable, but they do not last forever.

Haller’s tankless water heater replacement services make it easy to upgrade to a more reliable and efficient system when the time comes.

Even tankless water heaters have a lifespan, and older units become less efficient over time. Replacing an aging system restores reliable performance and prevents unexpected breakdowns.

If you are calling for repairs more often, it may be more cost-effective to replace your unit. A new system saves money in the long run and reduces the stress of ongoing issues.

Fluctuating water temperatures or difficulty maintaining hot water can signal internal wear or failing components. A replacement ensures consistent, dependable hot water throughout your home.

If your system is no longer delivering the efficiency or output it once did, it may be time for an upgrade. Newer tankless models offer improved performance that shows up in your monthly energy bills.

Tankless water heaters can last 15 to 20 years or more with proper maintenance. A unit in that range with performance issues is usually a candidate for replacement before a failure forces the decision.

Tankless Water Heater Maintenance

Tankless water heaters need service from time to time to extend the life of your unit and prevent unexpected issues.

Scale buildup from mineral content in local water makes annual maintenance especially important for tankless systems in this region. Consistent maintenance delivers the following benefits:

A descaled, properly calibrated tankless system runs at its rated efficiency, which shows up in your monthly utility costs. 

Regular descaling and inspection protect the heat exchanger, often pushing your system past the 20-year mark.

Issues caught during maintenance do not turn into the mid-winter shutdowns that leave you without hot water.

A maintained tankless system delivers the on-demand performance it was built for, even across simultaneous household use.

Professional Tankless Water Heater Installation

Haller’s tankless water heater installation services bring efficient, on-demand hot water to your home.

Our team helps you choose the right system and ensures a seamless installation for long-lasting performance and comfort.

If your current system cannot keep up with your household’s demand, a tankless water heater provides continuous hot water whenever you need it. This is especially useful for larger families or homes with multiple simultaneous hot water needs.

Tankless systems heat water only when needed, which eliminates the standby energy loss a tank water heater produces. Installing one lowers utility bills while improving overall efficiency.

A tankless water heater is a great fit for new construction or home renovations where you can plan for modern, space-saving solutions. It offers flexibility in placement and long-term performance benefits.

Traditional water heaters take up significant room, while tankless units are compact and wall-mounted. Upgrading reclaims valuable space in your home without sacrificing performance.

Tankless water heaters can last 15 to 20 years or more with proper maintenance, which is longer than most tank systems. That longer service life is one of the reasons homeowners upgrade when a traditional tank reaches the end of its useful life.

Tankless Water Heater FAQs

How long do tankless water heaters last?

Tankless water heaters typically last 15 to 20 years or more with proper maintenance. In Central Pennsylvania, where mineral content in the water contributes to scale buildup, regular descaling is a key part of reaching the upper end of that range.

Are tankless water heaters more efficient than traditional systems?

Yes, tankless systems only heat water when needed, which reduces energy waste. That efficiency translates into lower utility bills compared to a traditional tank water heater, especially in homes with steady year-round hot water demand.

How often should a tankless water heater be serviced?

Most manufacturers recommend annual maintenance to keep the system running efficiently. Homes with hard water, common across much of Central Pennsylvania, often benefit from more frequent servicing.

Can a tankless water heater supply enough hot water for my home?

Tankless systems provide continuous hot water, but proper sizing is important. Haller helps determine the right unit based on your household’s simultaneous demand so the system handles real use without performance drop-off.

What should I do if my tankless water heater stops working?

If your system is not working properly, call a professional for diagnosis and repair. Tankless systems have specific venting, gas, and electrical requirements, and Haller offers 24/7 emergency service to restore your hot water as quickly as possible.
