Water heaters in Maryland: what to know
Older heaters may share a chimney with the furnace, which has to be checked at replacement. Cold winter water makes heaters work harder.
Replacements need a permit and a licensed plumber.
Suburban homes with basements often keep the heater beside the furnace. Baltimore's Department of Public Works supplies water to the city and much of the region, and annual flushing helps tanks last.
- Climate
- Maryland gets periodic hard freezes and ice storms, often after mild spells, which catch exposed pipes off guard. Pipes in crawl spaces, exterior walls and garages are the first to freeze.
- Typical foundations
- Baltimore's older rowhouses often have original cast-iron and galvanized pipe, while suburbs have newer construction with 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.
