FAQs

One of the most common issues with tankless water heaters is a lack of hot water or inadequate water temperature. This can be attributed to several factors:

  • Flow Rate: If demand exceeds the unit’s maximum flow rate, it might struggle to provide consistently hot water, especially in larger households.
  • Mineral Buildup: Hard water areas can lead to mineral buildup inside the unit, reducing its efficiency and affecting heating.
  • Cold Water Sandwich: Some tankless units experience a brief moment of cold water between hot water bursts, known as a cold water sandwich.
  • Gas Supply: Gas-powered units require proper gas supply and pressure. Inadequate gas supply can lead to insufficient heating.
  • Venting Issues: Improper venting can impact combustion and cause heating problems.
  • Scale Formation: Scaling due to minerals can lead to reduced heat transfer efficiency.

Regular maintenance, proper installation, and choosing a unit that matches your household’s needs can help mitigate these issues. Consulting a professional plumber for maintenance and troubleshooting is advisable.

A tankless hot water heater might not be working for various reasons:

  • Power Supply: Check if the unit is receiving electricity or gas supply. Tripped breakers or gas supply issues can cause problems.
  • Flow Rate: Tankless heaters have a minimum flow rate requirement. If water flow is below this threshold, the unit might not activate.
  • Ignition Failure: Gas units require proper ignition. Ignition failure can result from gas supply issues or a faulty igniter.
  • Overheating: Overheating can trigger the safety shut-off feature, stopping the unit from heating.
  • Mineral Buildup: Scaling from hard water can block heat exchange, affecting performance.
  • Venting Issues: Improper venting can lead to combustion problems and shutdown.
  • Error Codes: Most units have error codes for diagnostics. Consult the manual to understand the issue.

If you’re unable to troubleshoot the problem, it’s best to contact a professional plumber or technician experienced with tankless water heaters for accurate diagnosis and repair.

Yes, tankless water heaters do require maintenance to ensure optimal performance and longevity:

  • Flushing: Regularly flushing the unit helps remove mineral deposits that can accumulate in the heat exchanger, improving efficiency.
  • Vent Inspection: Checking and cleaning the vent system ensures proper combustion and exhaust.
  • Air Intake: Ensure the air intake is free from obstructions for proper combustion.
  • Water Filter Cleaning: Some units have water filters that need cleaning to prevent clogs.
  • Gas Line Inspection: Gas-powered units require a thorough gas line inspection to ensure proper supply and pressure.
  • Electrical Connections: Check wiring and connections for any issues.
  • Anode Rod: Some units have an anode rod that should be checked and replaced if necessary to prevent corrosion.

Regular maintenance can extend the lifespan of your tankless water heater, maintain efficiency, and prevent common problems. It’s recommended to follow the manufacturer’s guidelines or consult a professional plumber for maintenance schedules and procedures.

When a tankless water heater fails, several issues can arise, impacting your access to hot water and potentially causing inconvenience:

  • No Hot Water: The most noticeable consequence is the lack of hot water, which can disrupt daily tasks like showering, cleaning, and cooking.
  • Cold Water Sandwich: Some tankless units might produce bursts of cold water in between hot water, known as a cold water sandwich, making your experience uncomfortable.
  • Error Codes: Many tankless units display error codes indicating the specific issue. Ignoring these codes can lead to prolonged heating problems.
  • Reduced Efficiency: A failing unit might struggle to heat water efficiently, leading to higher energy bills.
  • Leakage: Internal components like valves or connections can develop leaks, causing water damage.
  • Safety Risks: Gas-powered units can pose safety risks if combustion is compromised.

When a tankless water heater fails, it’s advisable to consult a professional plumber or technician experienced with these systems. Timely repairs or replacements can restore hot water and prevent further complications.

    Water heater needed to be replaced as well as hot water line. Bath tub was replaced with stand up shower as well as sink faucet and plumbing. Mana was a solid guy came early, worked late what should have been a three man job Mana did by himself. He even dry walled. Solid job by one solid brahdah.

    Mel Decasa
    Had leaking kitchen faucet with a large sink that needed a professional. Initially the online request sent a confirmation that someone would contact me, but since nobody did, I called, and received an apology, along with the person confirming that it would be noted that the online feature didn't file my request.The next available appointment was 2 days later, though I was put on priority wait list. The next day I got a call that there was an opening, and Teran gave thorough inspection and explanation. I asked if I could add on another sink that was leaking, and Teran said there would be no problem. He also asked if he could inspect the rest of the house. He provided 3 estimates, with the lowest being just for the kitchen faucet. We chose to fix just the Kitchen, though it was helpful to have an assessment of potential problems to watch for. Teran was efficient, friendly, informative, and considerate. We need more like him.
    armando barreiro
    Great service and even better customer service. Tyi was great.
    Kamu Rā
    Tarin did an amazing job. He exceeded our expectation. The resident manager and I (homeowner) appreciated his positive attitude and professionalism. He explained everything to detail and had visuals (pictures) to go along with it. Would highly recommend Tarin working on any job.
    Candace Goo
    Customer service was excellent and someone was able to come by the day I called. Jai was thorough and worked quickly to meet our needs. He did an amazing job and was very easy to work with.
    Lance Moriwaki
    Kai was on time, friendly, professional, and knowledgable.He took the time to explain necessary things, but did not take too long for the overhaul job to be completed. He seemed genuinely happy to be helping me out with my plumbing.
    Chase Conching
    Jai and the entire All Aloha Plumbing group were friendly and professional from day one. They were able to come out on short notice, give me three estimates (with good, better, best options) and perform all the work needed within a 72-hour timespan. No other company I reached out to was able to do that. AAP provided fair and transparent prices, and was even willing to guarantee their work for a much longer time period than their competition. I would highly recommend Jai and the All Aloha Plumbing crew for peace of mind that your plumbing issues will get fixed, for good.
    Jeffrey Acebedo
    All Aloha Plumbing responded to my request on yelp. Heather helped me schedule my appt. Stephanie did a follow up call. My technician Jai was very professional and knowledgeable on my toilet repair, he explained & showed the damages of the toilet. Jai did an excellent job from start to finish. Thank You.
    Diane Shito
    Ty was very helpful and professional. He did excellent work and was very thorough. Very considerate in keeping in mind with my budget. I will definitely recommend All Aloha Plumbing and will definitely call Ty for all my plumbing repairs.
    Dean Yamaguchi
    Ty and Joe were the technicians on the visit. They assessed the problem of a non-draining bathroom sink and while the initial estimate given to clean out the drain was acceptable, they adjusted the charges to reflect time spent to clean the drain which was a pleasant surprise! Also gave a kupuna discount which was also great. Drain runs well now. Guys were on time within the window given and did a great job!
    Emma Toilolo
    Called Saturday, spoke to Stephanie who helped me schedule my repair visit for Monday (only day available because of work) with Ty. Kept me informed and follow up with a call and an email. Tech Ty arrived, assessed the work I wanted/needed done, gave me options and started on the job asap. Replaced old pressure regulator (which was running high) and replaced the old corroded shower water valve (American Standard-no longer available). All done in one day!!Note: developers (Gentry) built with low grade pipes that becomes brittle over time. Ty had to do more than a simple job, putting more doable pipe and connectors. We are at peace knowing the job is done right with warranty to back the work.Mahalo! All Aloha Plumbing, Stephanie and Ty!! Job well done!!
    Kazu Okumura
    Jai was prompt and diagnosed the issue right away. Drain was cleaned in under an hour. Very professional and will call again for future plumbing issues.
