Water heaters in Idaho: what to know
At higher elevations, gas water heaters need venting and sizing for altitude. Fast growth around Boise means many homes built since the 1990s are on their first or second heater, and tankless units are common in new construction.
Replacements need a permit and a licensed plumber. Annual flushing and, on hard well water, a softener help tanks last.
- Climate
- Hard freezes are a regular part of winter in Idaho, so pipes in exterior walls, garages, crawl spaces and attics need protection every year, and outdoor faucets and sprinkler lines must be drained before the first freeze.
- Typical foundations
- Fast-growing suburbs around Boise mix with rural properties on private wells and septic systems. Most common: basements.
Water heaters services
Water heater repair
If a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat. Those parts are repairable. A tank that leaks from the bottom can't be repaired and needs to be replaced.
Water heater replacement
A leaking tank or a heater past about 10 years old is usually replaced rather than repaired. A proper install includes a permit, correct venting (adjusted for altitude where needed), an expansion tank where required, a drip leg on the gas line and a relief valve discharge pipe.
Tankless water heaters
A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation. Installed correctly and descaled regularly, it can outlast a tank heater.
