Tank to Tankless Conversions in Lexington
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 dispose of your old tank and patch the old flue penetration.

Hard Water Protection for Tankless Units in Lexington, NE
Calcium scale is the most common cause of tankless heater failure. Some rural wells also show elevated nitrates, which is why regular testing is recommended for any home on a private well. 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 added protection.

Frequently Asked Questions About Tankless Water Heater Installation in Lexington
The cost of tankless water heater installation in Lexington 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.
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.
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 soon as possible.
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 intricate venting systems, all of which require specialized knowledge and adherence to safety codes. Incorrect installation can be dangerous and void warranties.
Absolutely. 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 units eliminate standby heat loss, which can reduce water heating energy use. Savings vary based on household size and usage patterns.
Yes, tankless water heaters are very energy efficient in almost any climate. Sudden drops from mild to freezing weather expand and contract pipes and fittings, especially in older homes. Since they only heat water on demand, they avoid the standby heat loss common with traditional tanks, which can be significant even in milder seasons.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that considerably.
