  • Energy Efficiency, Tankless units heat water only when needed, which can lower your utility bills compared to traditional storage tanks.
  • Scale Protection, Isolation valves and scale filters protect the heat exchanger from hard water.

Cost-Effective Tankless Conversions in Janesville, WI

While the initial cost of a tankless water heater installation in Janesville, WI may be higher than a traditional tank, the long-term energy savings and longer lifespan often make it a more cost-effective solution. We provide detailed estimates, outlining the benefits and available rebates, to help you make an informed decision for your home.

Tank to Tankless Conversions in Janesville

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.

Residential Tankless Water Heater Installation in Janesville

HKV Plumbing focuses on installing tankless water heaters for residential properties. We assess your home's hot water demands, family size and existing utility connections to recommend the most suitable unit, so you get the right capacity for your needs. Our installations are designed to be energy efficient, providing endless hot water while often lowering your monthly utility bills in Janesville.

Hard Water Protection for Tankless Units in Janesville, WI

Calcium scale is the leading cause of tankless heater failure. Water softeners are a standard feature in many Wisconsin homes, helping protect water heaters, fixtures and appliances from scale. 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.

If your old tankless unit is failing or you are upgrading from a traditional tank, HKV Plumbing offers smooth tankless water heater replacement.

Frequently Asked Questions About Tankless Water Heater Installation in Janesville

The cost of tankless water heater installation in Janesville typically 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.

Tankless units eliminate standby heat loss, which can lower water heating energy use. Savings vary based on household size and usage patterns.

Size depends on how many fixtures run at once and your incoming water temperature. Many homes need a unit rated around 7 to 10 gallons per minute.

Fluctuating water temperature, error codes, reduced flow and unusual noises are common signs. Scale buildup is often the cause in hard water areas.

A straight replacement takes four to six hours. Tank to tankless conversions with gas and venting changes typically take a full day.

A standard tankless water heater installation, replacing an existing tank, usually takes 4 to 8 hours. If extensive plumbing or gas line changes are required, it may take a full day. Our team works efficiently to restore your hot water as quickly as possible.

Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also warranty our installation labor.

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 use a licensed professional.
