Rinnai, Navien and Noritz Installation in Rexburg, ID
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 known for durable commercial-grade heat exchangers. We help you compare models based on flow rate, efficiency and warranty.
Recirculation Systems for Tankless Heaters in Rexburg
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 suit your plumbing layout and usage patterns.
Hard Water Protection for Tankless Units in Rexburg, ID
Calcium scale is the most common cause of tankless heater failure. Private wells serve a large share of rural homes, and iron, sediment, and nitrates make regular well water testing a good habit. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides extra protection.
Tank to Tankless Conversions in Rexburg
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 often 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 dispose of your old tank and patch the old flue penetration.
Electric Tankless Water Heater Installation in Rexburg, ID
Electric tankless water heaters are an excellent option for homes in Rexburg where natural gas is not available or preferred. These units are often smaller, simpler to vent and can be installed closer to the point of use. HNV Plumbing provides expert electrical sizing to make sure your home's panel can safely support a new electric tankless unit, offering consistent hot water without the need for a gas line.
