What a water heater in Aberdeen is up against
Winter nights here average 26°F from December through February, and groundwater coming into the tank is cold for the seven months homes run their heat, October through April. A new water heater has to recover from that cold water every time someone runs a shower or fills the washer.
Aberdeen sees its share of winter storms and wind, and across Maryland about 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep making hot water through an outage like that. An electric one won't, but it will come back on by itself once power returns, no relighting needed.
Whatever you install has to meet the federal minimum efficiency for its size. That minimum isn't one number. It's set by a formula tied to the tank's rated volume, and it's worked out separately for four different draw patterns, so two tanks of the same type but different size answer to different minimums.

A heat pump water heater would save about $370 a year to run in Maryland compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Water pooling at the base of the tank is the clearest sign, since it usually means the tank itself is rusting through and that cannot be repaired. Water that comes out rusty or metallic tasting points the same way. A unit that is struggling to keep up with hot water demand or making rumbling noises from sediment buildup is worth replacing before it fails outright, rather than after it floods a closet or utility room. If the tank is still sound but repairs are getting frequent, a contractor can tell you whether another repair makes sense or whether the tank is done.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on which type is better in general. A tankless unit heats water as it flows through rather than storing it, so it does not run out of hot water the way a tank can during heavy use. It also takes up less space and tends to last longer than a storage tank. Against that, a tankless unit usually costs more to install and may need changes to your gas line, venting, or electrical supply depending on the model. A contractor can look at your current setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The main change is that hot water is made on demand instead of stored ahead of time, so there is no tank sitting full and ready. This usually means different venting, since tankless units vent differently than most tank models, and it can mean upgrading the gas line or electrical circuit to supply enough power for the unit to heat water quickly. The unit itself mounts on a wall and takes up much less floor space than a tank. Because the venting and hookups differ from a tank setup, this is a job that needs a permit and inspection through the local building office, and a licensed contractor will know what your specific model requires.
