Water heater replacement for Boise homes

Most replacements are like-for-like: same fuel, same size, same spot. It's also the moment to check whether the old install was correct, because venting, gas line and expansion tank problems are common in older basements.

Water heater replacement in Boise: what's different

Hard water leaves mineral buildup in Boise water heaters, shortening their life and reducing efficiency. Rapid growth has added many new subdivisions where homes are now reaching their first replacement.

Older North End and East End homes may have heaters in tight basements with venting that needs updating. Adding an expansion tank and replacing the shutoff valve are common at replacement.

Veolia Water Idaho supplies water to much of Boise, and permits come from the City of Boise Planning and Development Services. Flushing the new tank once a year helps it last.

Water heater replacement questions in Boise

How long do water heaters last in Boise?

Typically 8 to 12 years. Hard water can shorten that without regular flushing.

Do I need a permit to replace a water heater?

In most U.S. cities and counties, yes. The permit triggers an inspection of venting, gas piping and the relief valve, which are the parts most likely to cause a safety problem.

What size water heater do I need?

A 40 gallon tank suits many 1 to 2 bathroom homes; 50 gallons is common for larger families. The first-hour rating on the label matters more than tank size alone.

Do I need an expansion tank?

If your home has a pressure reducing valve, a check valve or a backflow device on the main line, the system is closed and most codes require a thermal expansion tank at the water heater.
