Tankless Water Heaters in New Port Richey, FL
Tankless water heaters give New Port Richey homeowners and business owners a reliable way to get hot water on demand, without the energy waste of keeping a large storage tank heated 24/7.
R.J. Kielty Plumbing, Air, & Electric Inc. installs, repairs, and inspects tankless water heaters across Pasco County and the greater West Central Florida region. With more than 50 years of service and a team of licensed, certified technicians, we help residential and commercial customers choose the right system, install it correctly, and keep it running for years to come.
Our Tankless Water Heater Services in New Port Richey
R.J. Kielty offers complete tankless water heater services for homes and businesses in New Port Richey. We work with natural gas, propane, and electric units from major manufacturers including A.O. Smith, Rheem, and Bradford White.
Tankless Water Heater Installation
A properly sized and installed tankless water heater can last 20 years or more. Our licensed plumbers evaluate your household size, hot water demand, and existing plumbing and gas lines before recommending a specific unit. This prevents undersized systems that can’t keep up during peak usage, a common complaint when installation isn’t done right.
For gas-powered units, we handle all venting, gas line upgrades, and code-required permits. Electric tankless installations may require electrical panel upgrades, which our licensed electricians can complete in-house. Having plumbing and electrical expertise under one roof means fewer subcontractors, fewer delays, and a cleaner install.
Most residential tankless water heater installations take one day. We remove and dispose of your old tank unit, mount and connect the new system, and test everything before we leave.
Tankless Water Heater Repair
Tankless water heaters are durable, but they’re not maintenance-free. Common issues include mineral scale buildup (especially with New Port Richey’s hard water), ignition failures on gas models, and error codes triggered by flow sensor problems.
R.J. Kielty technicians diagnose and repair all major brands. We carry common replacement parts on our trucks, so many repairs are completed in a single visit. If your unit is beyond repair, we’ll give you an honest assessment and a quote for replacement, no pressure.
Signs your tankless water heater needs repair include fluctuating water temperature, reduced hot water flow, unusual noises, or error codes on the display panel. Don’t ignore these. Small problems caught early cost far less to fix.
Tankless Water Heater Inspection
Annual inspections help your tankless water heater run at peak efficiency and catch small issues before they become expensive repairs. During an inspection, our technicians flush the heat exchanger, check gas connections or electrical components, inspect the venting system, and test water flow and temperature output.
Flushing is especially important in our area. Pasco County water tends to be high in minerals, which creates scale deposits inside the heat exchanger over time. Left unchecked, this buildup reduces efficiency and can shorten the life of your unit by several years.
Benefits of Upgrading to a Tankless Water Heater in Florida
Florida’s warm climate gives tankless water heaters a performance advantage. Incoming groundwater temperatures here average around 72–77°F, which means the unit doesn’t have to work as hard to reach your desired output temperature. That translates to lower energy use and faster hot water delivery compared to colder climates.
Here’s what most homeowners notice after upgrading:
Lower energy bills. The U.S. Department of Energy estimates that tankless water heaters are 24–34% more energy efficient than conventional storage tank models for households that use 41 gallons or less of hot water per day. Even homes with higher usage see efficiency gains of 8–14%.
Unlimited hot water. A correctly sized tankless unit heats water on demand. No more cold showers because someone ran the dishwasher.
Space savings. Tankless units mount on a wall and take up a fraction of the space a 40- or 50-gallon tank requires. This matters in smaller homes, condos, and commercial spaces where every square foot counts.
Longer lifespan. Most tank water heaters last 8–12 years. A well-maintained tankless unit can last 20 years or more.
Potential tax credits. Certain ENERGY STAR-certified tankless water heaters may qualify for federal tax credits. Check the current IRS guidelines or ask our team for details during your consultation.
