Tankless Water Heater Replacement

Natural Gas Tankless Water Heaters

How do you know it’s time to replace your tankless water heater? You’ll probably notice the unit heating intermittently, not heating at all or you’ll see water pouring out of the unit. 

Age and condition make a big difference too. If you’ve maintained your unit since it was installed you’ll get a longer life span from it. We don’t recommend throwing money away on old units that are out of warranty or poorly maintained.

Another consideration to make is warranty. If the parts warranty has expired you may end up paying a hefty amount to repair the unit. Keep in mind once one repair is made to an older unit, it’s highly possible another part will malfunction. Timing for parts to be available may be longer than you want to wait. You may consider replacing your tankless water heater at this point because waiting 2 weeks or more for an expensive part(s) may not have much value.

We’ll check your tankless water heater and give you our honest opinion about your options. We treat each tankless water heater as if it were our own because we know they are not cheap.

Please make Hanahan Plumbing Co your choice for tankless water heater replacement. Let us show you what local, licensed and experienced really means.

Please Use A Licensed Plumber For Your Tankless Water Heater Replacement

It’s highly annoying to see improper tankless water heater replacements. Improper replacements create safety issues, void the water heater warranty and cause the unit to fail prematurely. If you want your the job done correctly, to code and manufacturer specifications call us at Hanahan Plumbing Co today. Our goal is to be the only tankless water heater replacement company you ever need to call again.

Steps To Replacing Your Water Heater

Call Us

We believe the first step in diagnosing your tankless water heater problem starts when you call us. You'll always speak to a plumber when you call HPC who will ask questions to get the diagnosis started.

Schedule Appointment

Scheduling a tankless water heater problem quickly is usually pretty important. Especially if it's leaking. We make every effort to replace your broken tankless water heater same day or next day.

Diagnosis/Price

In order to give you an accurate price we must visit your property to check the tankless water heater. We'll determine if replacement is the best route and identify any other issues before giving you a firm quote.

Replacement

Once we have agreed on the price we will obtain the water heater and perform the replacement. Most tankless water heater replacements take 4-6 hours if the original installation was done correctly.

Payment

Upon successful completion of the replacement we will ask for payment. HPC accepts cash, check and card.

Warranty

The final step is to register your tankless water heater replacement with the manufacturer for warranty purposes. HPC will register your new tankless water heater within 5 days of replacement.

Other Information Regarding Water Heater Replacements

Hanahan Plumbing Co provides Navien tankless water heaters for replacement. In some cases we may install Rinnai tankless water heaters.

HPC does not install water heaters provided by the owner because we will only warranty materials that we provide. We do not install or provide warranty service for water heaters purchased from Lowes or Home Depot. 

We get a lot of calls from homeowners wanting to know if we work with home warranty companies. The answer is no, we will not perform any work for a home warranty company nor will we provide them with diagnoses, price break downs or invoices. 

Hanahan Plumbing Co uses Navien natural gas tankless water heaters.

Navien Tankless Water Heater Installation

Hanahan Plumbing Co recommends Navien tankless water heaters for a number of reasons.
First, all of the Navien tankless water heaters we install have a built in thermostat on the front of the unit. This means you don't have to run wire into your home for a wall mounted thermostat.
Second, the units we install can be installed indoors or outdoors.
Third, the interior components are stainless steel.
Another thing we like is the workspace inside the unit which makes repairs easier than other brands. Did we mention that we only install the condensing units which have an excellent Energy Star rating.
Additionally, Navien doesn't require annual service for warranty purposes, although given the hard water conditions around Charleston it is recommended.
Finally, the only repairs we've ever made to the Navien water heaters we've installed were caused by nearby lightning strikes which created a surge and damaged the PCB, so their track record with us is strong.

We also provide annual tankless maintenance
