A scale inhibitor cartridge or whole-home softener provides extra protection.

Frequently Asked Questions About Tankless Water Heater Installation in Biloxi
The cost of tankless water heater installation in Biloxi usually ranges from $2,500 to $4,500, including the unit and labor. This can vary based on the model, fuel type (gas or electric) and any necessary upgrades to your gas lines or electrical panel. We provide a detailed, upfront quote after an on-site assessment.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that significantly.
While it may seem appealing, tankless water heater installation is complex and should only be performed by a licensed professional. It involves gas lines, high-voltage electricity, water connections and detailed venting systems, all of which require specialized knowledge and adherence to safety codes. Incorrect installation can be dangerous and cancel warranties.
Size depends on how many fixtures run at once and your incoming water temperature. Most homes need a unit rated around 7 to 10 gallons per minute.
We install leading tankless water heater brands known for their reliability and efficiency, including Rinnai, Navien, Noritz and Rheem. Our plumbers are trained and experienced with the specific requirements of each manufacturer to ensure strong performance.
Tankless units eliminate standby heat loss, which can reduce water heating energy use. Savings vary based on household size and usage patterns.
Most tankless water heaters come with a manufacturer's warranty of 10 to 15 years on the heat exchanger and 3 to 5 years on parts. DFM Plumbing also provides a warranty on our installation labor, which we will spell out in your service agreement.
Yes, tankless water heaters are very energy efficient in almost any climate. Water heaters in hot garages and attics age quicker, so their condition is worth checking during any plumbing visit. Since they only heat water on demand, they avoid the standby heat loss common with traditional tanks, which can be substantial even in milder seasons.
