About tankless water heaters
Repairs for Tankless Water Heaters
If you ever need tankless water heater repair, the technicians at Blanton & Sons will be there to help! Knowing how to spot problems with your water heater will ensure that they can be solved sooner rather than later. One of the telltale signs that your tankless water heater requires repair is a noticeable drop in water temperature. If you find your hot water is not as hot as it used to be or if there are sudden bursts of cold water during use, it may indicate a malfunction.
Additionally, loud noises coming from the water heater, such as banging or popping sounds, can signal problems like mineral buildup or issues with the heating element. Any deviation from the usual performance should prompt immediate attention from professional water heater repair services to address the problem and prevent further damage. Prompt intervention can help keep your tankless water heater in peak condition, ensuring its longevity and energy efficiency.
Tankless Water Heater Installations
If you’re interested in upgrading to a tankless hot water heater system, we’ll happily lend a hand with the installation! Unlike a traditional water heater that stores and continually heats a large amount of water, a tankless system heats water on demand — resulting in significant energy savings and lower monthly bills.
The compact design of tankless water heaters not only saves space but also reduces the risk of sediment buildup, ensuring a longer lifespan. Additionally, the energy-efficient nature of tankless water heaters contributes to a positive impact on the environment. With properly installed tankless water heater systems, homeowners can enjoy a constant and endless supply of hot water, making it an excellent investment for households seeking both convenience and sustainability.
Replacements for Old Tankless Water Heaters
While tankless water heaters are known for their durability and energy efficiency, they are not immune to wear and tear over time. Eventually, you may need to schedule a replacement — but when will that be? On average, a well-maintained tankless water heater can last 20 years or more. However, certain signs may indicate the need for replacement. A decline in hot water quality, such as rusty or discolored water, can signal internal corrosion or mineral deposits, affecting the unit’s performance.
If emergency water heater repair becomes a frequent necessity or the system is approaching the end of its expected lifespan, homeowners should consider a replacement to avoid potential issues and ensure the continued efficiency of their hot water supply. Regular maintenance and attention to these signs can extend the life of a tankless water heater and contribute to long-term savings on energy bills.

What Our Customers Say
Had the pleasure of doing business with Blanton and Sons. Wesley is the most competent Plumber I have ever dealt with in my career. Very impressive! He was on time, respectful, knowledgeable, and gave me all my options explaining them thoroughly allowing us to decide what was best for our home. It seemed to be going too well. The project went off without a hitch exactly how Wesley described when explaining the process and the quality of work was impeccable! If your reading this look no further than the Blanton crew!
Derek H.
Our hot water heater conked out on us and I reached out to Blanton & Sons the next morning. Kayla got in touch to see if someone could come by to help us. Wesley was able to work us in and by that afternoon he was able to bring the materials back to the house. He was finished the install and put us back into “hot water” that same day. He is a very nice well-mannered, helpful young man. Kayla was great to work with also. This is the second time they were able to help us out with a project. I highly recommend Blanton & Sons for your HVAC and plumbing needs.
Cheri F.
Highly recommend this company! The appointment was super easy to make and they were able to send someone out quickly. Gary, our plumber,was very polite, professional, and informative. He not only made the repairs needed but informed us of what the problems were and how he was going about fixing them. We let him know we were moving soon and he told us about their regular maintenance program and I’m definitely interested. It’s so nice to have a solid contact you know you can trust when you need them!

Frequently Asked Questions
Is a tankless water heater worth it?
For many households, yes. Tankless units provide endless hot water, last 20+ years versus 10–15 for a tank, take up far less space, and use less energy by heating only on demand. The trade-off is a higher upfront cost, which financing can spread out.
Will a tankless unit really give me unlimited hot water?
Effectively yes — it heats water as it flows, so it won’t run out the way a tank does. The limit is flow rate: a properly sized unit handles simultaneous demands like a shower and dishwasher, but undersizing causes drops. We size it to your household’s peak use.
How much does tankless installation cost?
More upfront than a tank unit, because installation can involve gas line, venting, or electrical upgrades. We assess and quote it precisely, with a $0 dispatch fee and financing including 0% for 12 months for qualified buyers. Call (843) 256-6454.
Does tankless need special maintenance in our area?
Yes — periodic descaling matters, especially with the Lowcountry’s mineral content, since scale can build in the heat exchanger. Many owners pair a tankless unit with water filtration or softening to reduce scaling and protect efficiency.
Can I switch from a tank to tankless?
In most homes, yes. The conversion may require gas-line, venting, or electrical changes depending on the unit, which we evaluate up front. We install both types and will give you an honest comparison before you commit.
