Why Choose FKM Plumbing for Tankless Water Heater Replacement in Mission Viejo, CA?
Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. Hard water is tough on tankless heat exchangers, and many early failures trace back to scale and skipped flushing. We size, install and set up each replacement so it stands up to your local water supply.
- Space Saving, Their compact design allows tankless units fit in smaller spaces, freeing up useful room in your utility closet or garage.
- Increased Lifespan, Modern tankless water heaters often last much longer than conventional tank models, offering a better long-term investment.
- Clean Venting, We route venting to meet manufacturer clearances from windows, doors and rooflines.

Tank to Tankless Conversions in Mission Viejo, CA
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.
Tankless vs. Tank Water Heater Replacement Cost in Mission Viejo, CA
When considering tankless water heater replacement in Mission Viejo, CA, it is natural to compare costs.

The cost of tankless water heater replacement in Mission Viejo, CA typically ranges from $3,000 to $6,000, depending on the unit's capacity, brand, complexity of installation, such as converting from a tank model, and any needed electrical or gas line upgrades.

With proper installation and regular maintenance, a new tankless water heater usually lasts 20 to 25 years. This is significantly longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in hard water areas.
DIY tankless water heater replacement is generally not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to dangerous gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like FKM Plumbing.
FKM Plumbing installs and replaces all major reputable brands of tankless water heaters.

They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to significant savings on your utility bills over time, particularly in homes with varying hot water usage.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to extra plumbing, gas or electrical changes required for proper installation and venting.
Yes, you can absolutely replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners seeking better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation important for safety and performance.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit for you.
