Tankless Water Heater Installation Services
You only get those benefits when the right unit is installed the right way. Every home’s plumbing, gas, and electrical setup is a little different, so a tankless installation is never one-size-fits-all. We install quality units from trusted manufacturers, including Rheem, Navien, and Bradford White, and handle every connection to current plumbing, gas, electrical, and venting code.
Gas and Electric Tankless Installation
We install both gas and electric tankless water heaters, with particular expertise in gas tankless systems. Gas units deliver strong, steady hot water for larger households, while electric units work well in homes without a gas supply or with less hot water demand. We’ll help you choose the type that fits your home’s utilities and how your family uses hot water.
Tank-to-Tankless Conversion
Many San Diego homes still have a traditional storage tank. Converting to tankless means removing the old tank and preparing your home’s gas, venting, or electrical connections to support the new unit. We handle the full conversion, from removing the old tank to testing of the new system.
Recirculation-Compatible Installation
If your home has a hot water recirculation system, which keeps hot water moving through your pipes so it reaches the tap faster, we can install a compatible tankless unit so you keep that convenience. You get hot water at the tap quickly without the energy cost of heating a full tank.
Tankless Water Heater Installation in San Diego
Running out of hot water halfway through a shower, nursing along an aging tank, or living with a water heater that can’t keep up with your household can make every morning harder than it should be. A tankless system gives you on-demand hot water from a compact unit that mounts on the wall. Permanent Solutions Plumbing & Drain provides tankless water heater installation, repair, and maintenance for homeowners throughout San Diego, with licensed technicians who size and install your system correctly the first time. Call (760) 805-1155 or request a callback to talk about going tankless.
Why Choose a Tankless Water Heater?
A traditional water heater keeps a large tank of water hot around the clock, whether you need it or not. A tankless unit works differently: it heats water only when you turn on a hot water tap, then shuts off when you’re done. That simple change brings several practical benefits.
Hot water that doesn’t run out: There’s no tank to empty, so back-to-back showers and a running dishwasher won’t leave the last person with cold water.
Lower energy use: Tankless systems can be up to 34% more energy efficient than traditional tanks, which means less energy spent and lower operating costs month after month.
Space savings: A wall-mounted unit takes up a fraction of the room a storage tank needs, freeing up space in your garage, closet, or utility area.
Longer service life: A tankless water heater typically lasts about twice as long as a traditional tank, so you’ll replace it far less often.
No tank to fail: Without a large storage tank, there’s no risk of it rusting through and flooding the surrounding area.
Tankless Water Heater Repair and Maintenance
Tankless water heaters are built for reliable performance, but like any plumbing system, they can develop problems over time. Our approach is to find what is actually causing the issue before replacing any parts, so the repair holds.
Error code diagnosis: Tankless units display error codes when something goes wrong. We read and diagnose those codes to pinpoint ignition problems, sensor faults, flow issues, and other conditions.
Temperature and flow problems: Water that suddenly turns cold, temperatures that swing up and down, or weak hot water flow can point to mineral buildup, an ignition or component fault, or a unit that’s too small for your household.
Descaling: San Diego’s hard water leaves minerals behind inside the heat exchanger, the part that heats your water. Professional descaling flushes out that scale to restore efficiency and protect the unit.
Staying on top of maintenance like this also plays a big part in how long your unit holds up.
How Long Do Tankless Water Heaters Last?
With proper installation and regular maintenance, a tankless water heater can often last 20 years or longer. How long yours lasts depends on a few factors that affect how hard the unit works.
Water Quality and Maintenance: Mineral-rich water causes scale to build up inside the heat exchanger, which reduces efficiency, restricts flow, and puts added stress on the system. Periodic flushing removes those deposits before they cause damage, and routine service can catch worn parts before they fail.
Household Hot Water Usage: A system serving a busy household with high daily demand will see more wear than one with lighter use.
Proper System Sizing: A unit matched to your household’s hot water demand won’t be pushed beyond its intended capacity, and it keeps temperatures steady when several fixtures run at once.
Quality of Installation: Correct gas, electrical, plumbing, and venting connections are essential for safe, reliable operation over the life of the unit.
Even a well-maintained system will eventually reach the point where frequent problems make replacement the better choice. Our team can assess your unit and tell you whether maintenance, repair, or a new tankless water heater installation is the right next step.
What Does Tankless Water Heater Installation Cost?
The cost of tankless water heater installation varies because every home’s plumbing and existing setup are different. The unit itself is only one part of the total project.
Factors that can affect the cost include:
System Size and Capacity: A home with several bathrooms and high simultaneous hot water demand may need a higher-capacity unit.
Fuel Type: Gas and electric tankless systems have different installation and utility requirements.
Gas Supply: Some gas units need an upgraded gas line to deliver enough fuel to the new system.
Venting: Gas tankless units require proper venting, and the existing vent may need to be modified or replaced.
Electrical Capacity: Electric units may require panel or circuit upgrades to run safely.
Conversion From a Tank System: Replacing a storage tank with a tankless unit usually involves more work than swapping one tankless unit for another.
We look at your setup in person and give you an upfront, honest estimate before any work begins, with no surprises and no hidden charges.

Frequently Asked Questions
Still weighing your options? Here are answers to the questions San Diego homeowners ask us most about going tankless.
Is a tankless water heater worth installing?
For many households, yes. A tankless system offers continuous hot water, lower energy use, a longer service life, and a much smaller footprint than a tank. The value depends on your household’s hot water use, your existing setup, and how long you plan to stay in the home.
What size tankless water heater do I need for my whole house?
A properly sized tankless unit can supply your whole house. Size depends on how many fixtures may run hot water at the same time, the flow rate they need, and how much the unit must raise the temperature of incoming water. We match the unit to your home so it keeps up during your busiest times of day.
Can I replace a traditional water heater with a tankless system?
Yes. Most traditional tank systems can be converted to tankless, though some homes need modifications to existing connections before the new unit goes in. We’ll explain exactly what your conversion involves before work begins.
Do tankless water heaters need maintenance?
Yes. Regular descaling and flushing control mineral buildup, which is especially important with San Diego’s hard water. How often your unit needs service depends on water quality, household usage, and the manufacturer’s recommendations.
How long does tankless water heater installation take?
Most service calls are completed the same day. A straight replacement of an existing tankless unit is usually quicker than a tank-to-tankless conversion, and we’ll give you a more specific time window when your appointment is confirmed.
