Water heaters in New Hampshire: what to know
Well water may have minerals or sediment that shorten tank life, and a heating outage in deep cold can freeze both heating and domestic water lines.
Replacements need a local permit and a licensed plumber. Annual flushing and checking venting on gas units help.
Older mill-city buildings often have several tanks in one basement.
- Climate
- Hard freezes are a regular part of winter in New Hampshire, 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
- Many homes are older and rely on private wells and septic systems, and most have basements. 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.
