Tankless Water Heater Installation & Repair

A tankless water heater can be a smart fit when your home needs steady hot water without relying on a large storage tank. Full Spectrum Plumbing installs, replaces, repairs, and maintains tankless water heaters with careful attention to sizing, venting, fuel type, water quality, and daily household demand.

Unlike a standard tank system, a tankless unit heats water as it is needed. That makes the setup more compact, but it also means the system has to be matched correctly to your home. A unit that is too small may struggle during back-to-back showers, laundry, or dishwasher use. A unit that is installed without the right gas, electrical, or venting setup can create performance issues from the start.

Our plumbers help you choose the right system, install it properly, and keep it working the way it should.

Tankless Water Heater Installation and Replacement

Switching to tankless is not just a simple equipment swap. The right installation depends on how much hot water your home uses, how many fixtures may run at once, and whether your current plumbing, gas, venting, or electrical setup can support the new unit.

Full Spectrum Plumbing can help with:

  • New tankless water heater installation

  • Replacement of an aging tankless unit

  • Converting from a traditional water heater to a tankless model

  • Gas line checks or upgrades for gas tankless systems

  • Venting and drainage requirements

  • System sizing based on real household use

We do not recommend a tankless system just because it sounds newer. We look at the home first, then explain whether tankless makes sense.

Tankless Water Heater Repair

Tankless systems are efficient, but they are also sensitive to flow rate, mineral buildup, ignition problems, error codes, and improper installation. When something is off, the symptoms can show up as cold bursts, weak hot water, shutdowns, or inconsistent temperatures.

Our plumbers troubleshoot tankless water heater problems carefully before recommending a repair or replacement. Common issues include:

  • No hot water

  • Water that turns hot, then cold

  • Error codes on the unit

  • Ignition or burner problems

  • Mineral buildup inside the heat exchanger

  • Poor flow through the system

  • Venting or drainage issues

  • Undersized equipment for household demand

When the problem is connected to water quality, we may also recommend looking at water filtration or water softeners to help reduce scale and protect the system over time.

Tankless Water Heater Maintenance

Tankless water heaters need routine maintenance to keep them running efficiently. Mineral buildup can restrict flow, strain the heat exchanger, and shorten the life of the unit. This is especially important in homes with hard water.

Tankless maintenance may include flushing the unit, checking filters, inspecting venting, reviewing error history, and confirming that the system is heating consistently. For homeowners who want regular plumbing maintenance handled on a schedule, Full Spectrum’s service agreements are a natural fit.

Is a Tankless Water Heater Right for Your Home?

A tankless water heater may be a good option if you want more consistent hot water, need to free up space, or are replacing an older tank unit. It may not be the best fit if the home would require major upgrades that outweigh the benefit.

We help you weigh the practical details:

  • How many people use hot water daily

  • Whether multiple fixtures often run at once

  • Current water heater age and condition

  • Available gas, electric, and venting capacity

  • Water hardness and maintenance needs

  • Long-term repair versus replacement cost

The goal is not to oversell the system. The goal is to make sure your water heater fits the way your home actually uses hot water.

Mr. Jackie, Travis, and Logan were extremely helpful getting a massive pipe leak at the meter box on our property fixed in a timely manner after a nightmare running around for quite a few days with other plumbers and the city. The service from start to finish was absolutely amazing. The level of transparency and honesty given was greatly appreciated with a job such as tedious as ours. I appreciated the thoroughness they provided in their explanations. We will certainly be using them for any other plumbing needs and I recommend anyone needing any type of plumbing services to reach out to these guys!

Brandon was absolutely amazing! He camd out to look at our toilet that was leaking, and discovered our pressure was too high. He recommended installing a new pressure regulator to help get the pressure back within a safe range. Would highly recommend asking for him for any of your plumbing needs!

Justin was very helpful and knowledgeable. Explained what he was doing and why during the full repair. Never felt pressured to buy something that I didn't feel wasn't needed. This is by far my go to company if I need plumbing services in the future. Must also mention Latisha from my call in for service, she was very sweet and made me feel that my small service job was as important to handle today as a big profitable request. I have Full Spectrum Plumbing added to my service list of vendors. Thanks everyone for your help today!!!

Today I needed work done ASAP! From the A1 person booking the appointment to Brandon being at my door by 9:45 am the service was fast, efficient and very timely. I was fortunate to have googled them today. I must say they are a bit pricey for the work I needed done but you get what you pay for.
