Nine months of heating puts steady demand on a water heater
Mountain Lake Park needs heat from September through May, and winter nights average 21°F from December through February. That means a water heater here is working most of the year, not just a few summer months, and the incoming water it has to warm is colder for longer.
Power loss is worth planning around too. Maryland saw 11% of households lose power for 24 hours or more in 2024, and this area has logged 63 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One that runs on electric ignition will not light again until power is back. Whatever you install, it has to meet the federal minimum efficiency for its size and type, since the standard is set separately for each tank volume and draw pattern rather than one number for every heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that isn't hot anymore, or runs out fast when it used to last. Rust colored water, a tank that's rusting or swelling on the outside, or water pooling underneath are all signs the tank itself is failing, and a leaking tank needs replacing, not repairing. If it's making rumbling or popping noises, sediment has built up on the bottom, and that shortens what's left of its life. If your water heater is old and starting to act up, it's worth having a contractor look at it before it fails on its own schedule instead of yours.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just what's failed on your current one. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry, and it takes up much less space than a tank. Switching usually means changes to the gas line, venting, or electrical setup, since tankless units have different requirements than a storage tank. A contractor can look at your home and tell you what that would involve here.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, but what feeds it usually has to change too. Tankless heaters draw more gas or more electricity at once than a storage tank does, so the gas line or the electrical circuit often needs upgrading to handle it. Venting is different as well, since tankless units vent differently than a standard tank. Because of that, a straight swap is rare. A contractor will need to check your home's gas, electrical and venting setup before pricing the job, and the work will need a permit and inspection from the local building office, same as replacing a storage tank does.
