Tankless Water Heater Installation in Escondido and North County San Diego
A tankless water heater can give you hot water without keeping a full tank heated all day, but the unit has to fit the home. Gas supply, venting, electrical power, water quality and the number of fixtures all affect whether a tankless system will work the way you expect.
True Plumbing installs and replaces tankless water heaters for homeowners in Escondido and across North County San Diego. We start by looking at the home and the existing system, then explain the work before an installation is scheduled. Call (760) 637-5355 or book a tankless water heater assessment.
Recent Job: Tankless Replacement in Carlsbad
A Carlsbad homeowner called us about a 13-year-old Rheem tankless water heater that was due for replacement. We assessed the existing setup and replaced it with a Navien NPE-240S2 condensing tankless unit. Because a condensing unit needs its own drain path, the job included condensate piping and a neutralizer, plus new 2-inch PVC venting run to an exterior wall. We also installed service valves with a flush kit, a water shutoff valve, an expansion tank and new gas piping with a sediment leg and gas shutoff, then hauled away the old unit. The installation was completed in one day.
Is Tankless Right for Your Home?
Tankless is often a good fit when you want to free up space, replace an aging system or plan for more consistent hot-water demand. It is not an automatic drop-in replacement for every tank water heater. Before recommending a unit, we check:
- How much hot water the home needs at peak use
- The incoming gas supply and whether it can support the selected unit
- Venting and combustion-air requirements
- Electrical power near the installation location
- Water, drain and condensate routing
- The condition of existing shutoffs and connections
- Local installation and permit requirements that apply to the job
If the existing setup needs changes, we show you what is involved before moving forward.
Our Tankless Installation Process
1. Assess the home
A plumber looks at the current water heater, installation location, utilities and expected hot-water demand. Conversions and new installations need an on-site assessment because the scope can vary a lot from one home to another.
2. Explain the options
We review the practical choices for the home, including unit sizing and any work needed for gas, venting, water, drain or electrical connections. If keeping a tank system makes more sense, we will say so.
3. Complete the installation
The old equipment is removed when included in the agreed scope. The new tankless unit and required connections are installed, then the system is started and checked for proper operation.
4. Walk through care and maintenance
Tankless systems need periodic descaling, especially with mineral-heavy water. We explain the maintenance schedule for the installed unit and how to recognize signs that service is needed.
Tankless Replacement and Conversion Work
- Replacement of an existing tankless water heater
- Conversion from a tank water heater to tankless when the home is a good fit
- New tankless installations where no existing unit is being replaced
- Installation of customer-supplied tankless units after the unit and site are checked for compatibility
- Tankless flushing and descaling
- Diagnosis of common tankless hot-water problems
New dedicated systems and conversions are priced after an on-site look. There is no responsible way to price or promise the work without seeing how the existing lines and utilities are arranged.
Tankless Maintenance Matters
Mineral buildup can reduce flow and make a tankless unit work harder. True Plumbing offers tankless descaling. The right maintenance interval depends on the unit, water conditions and manufacturer instructions. Signs that a tankless system may need service include:
- Hot water that turns cold during use
- Reduced hot-water flow
- An error code on the unit
- Unusual noise during operation
- A leak or moisture near the system
- Maintenance that has been skipped or is overdue
If there is an active leak, gas odor or loss of hot water, book service rather than trying to reset the unit repeatedly.

Tankless Water Heater FAQs
How do I know what size tankless water heater I need?
Sizing depends on the number of fixtures that may run at the same time, the temperature of the incoming water and the temperature rise the home needs. Model size should be selected after those conditions are checked, not by square footage alone.
Can you replace a tank water heater with a tankless unit?
Often, yes. A conversion may require changes to the gas supply, venting, electrical power, water lines or drain routing. An on-site assessment shows whether the conversion makes sense and what the work involves.
Can True Plumbing install a tankless water heater I already purchased?
We can assess customer-supplied equipment for compatibility with the home and the installation location. The unit, fuel type, capacity and required components need to be checked before the installation is accepted.
Does a tankless water heater need maintenance?
Yes. Periodic inspection and descaling help manage mineral buildup and keep the water path clear. The interval depends on water conditions, usage and the manufacturer’s instructions.
How long does a tankless installation take?
A straightforward replacement and a tank-to-tankless conversion are different jobs. Timing depends on the existing utilities, location, venting and the amount of connection work needed. We confirm the expected schedule after the site assessment.
Does True Plumbing provide 24-hour service?
No. True Plumbing handles emergency plumbing during business hours, but it is not a 24-hour company. Hours are Monday through Friday, 8 AM to 5 PM. Saturday and Sunday are closed.
