Rinnai Tankless Water Heater Installation in Derby, KS
Rinnai tankless water heaters are a popular choice for their reliability and long lifespan, making them a smart investment for homeowners across Derby, KS. Our plumbers are factory-trained on Rinnai systems, delivering a clean installation that follows all manufacturer specifications. We make sure gas line sizing, venting and water connections are correct so your Rinnai unit provides endless hot water reliably for years.

Tank to Tankless Conversions in Derby
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line usually needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and haul away your old tank and patch the old flue penetration.
Tankless Water Heater Replacement in Derby, KS
If your old tankless unit is failing or you are upgrading from a traditional tank, KRV Plumbing offers smooth tankless water heater replacement. We carefully remove the old unit, make any needed adjustments to plumbing and venting and install your new, more efficient model. Our goal is to make the transition as smooth as possible, ensuring continuous hot water in your Derby, KS home.
Rinnai, Navien and Noritz Installation in Derby, KS
We install leading tankless brands including Rinnai, Navien, Noritz and Rheem. Rinnai offers a wide model range and strong parts support, while Navien condensing units often include built-in recirculation pumps. Noritz is recognized for durable commercial-grade heat exchangers. We help you compare models based on flow rate, efficiency and warranty.
Tankless vs Tank Cost Comparison in Derby, KS
Tankless installation costs more upfront than a standard tank because of the unit price, gas line upgrades and venting changes. Over time, lower standby energy losses and a longer expected lifespan offset part of that cost. Tankless units often last 15 to 20 years with proper descaling, compared with about 8 to 12 years for many tanks in hard water areas. We give you a side-by-side quote so you can decide what suits your budget.
Upgrading from Tank to Tankless in Derby, KS
Making the switch from a traditional tank water heater to a tankless system involves more than just swapping units. It often requires changes to gas lines, electrical wiring and venting. KRV Plumbing manages all aspects of this conversion, making sure all upgrades meet current codes and your new tankless unit performs optimally, giving you a modern hot water solution in Derby, KS.
Recirculation Systems for Tankless Heaters in Derby
Tankless heaters can take a few extra seconds to deliver hot water to distant fixtures. A recirculation pump or dedicated return line keeps hot water close to faucets, cutting wait time and water waste. Some units have built-in pumps with smart scheduling. We design the system to fit your plumbing layout and usage patterns.

Residential Tankless System Upgrades in Derby
Upgrading your traditional hot water tank to a tankless system in Derby can significantly improve efficiency and comfort.

Frequently Asked Questions About Tankless Water Heater Installation in Derby
Most gas tankless installations cost $3,000 to $6,500 including the unit, labor, venting and common gas line upgrades. Electric units can be less, though panel upgrades can add $1,000 to $3,000.
We install Rinnai, Navien, Noritz and Rheem tankless water heaters. Each brand offers different features, efficiency levels and warranties.
Yes. When properly sized, a tankless water heater can provide an endless supply of hot water, even for large families. It is crucial to select a unit with a high enough GPM (gallons per minute) rating to meet your peak demand.
Tankless water heaters offer several key benefits: endless hot water on demand, real energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also reduce the risk of tank leaks and the water damage that comes with them.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that significantly.
Tankless units eliminate standby heat loss, which can lower water heating energy use. Savings vary based on household size and usage habits.
No, we firmly advise against DIY tankless water heater installation. These systems involve complex connections for gas, water and electricity, along with specific venting requirements. Improper installation can lead to safety hazards, void warranties and costly repairs. Always hire a licensed professional.
Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems in particular, frequent error codes or a significant drop in hot water flow could point to a need for service or replacement.
