Water heaters in Boise, ID
Most tank water heaters last about 8 to 12 years. A plumber can often repair a heater that stops making hot water, but a tank that leaks from the bottom has failed and needs to be replaced. Tankless heaters last longer but cost more to install, especially if the gas line or venting has to change.

Water heaters services in Boise
Water heater repair
UrgentIf 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 in Boise
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.
