What a Barnstable County winter asks of a water heater
Groundwater coming into the tank is cold here, and winter nights averaging 26°F from December through February make the burner or element work harder to hold temperature. The heating season runs eight months, October through May, so a water heater here is rarely working against mild conditions. It's on the clock most of the year.
Power matters too. About 10% of Massachusetts households went at least 24 hours without power in 2024, and the county has logged 14 winter storms and 249 damaging wind events over the past ten years. A standing pilot gas water heater keeps making hot water through an outage. An electric one, or a gas unit with electronic ignition, won't light again until power is back. Whichever you install, it has to meet the federal minimum efficiency for its size, which is set separately for each tank volume rather than as one number for every unit.

A heat pump water heater would save about $720 a year to run in Massachusetts compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Once a storage tank gets old, start planning for a replacement rather than waiting for it to fail. Rust-colored water, a tank that's damp or wet at the base, or water that won't get hot anymore are all signs the tank itself has failed, not just a part inside it. A puddle under the tank is not something to wait out. If your water heater is electric, remember that a power outage will bring it back on by itself once power returns, so if it's not heating, that points to the unit itself and not the outage.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your water heater being old. A tankless unit heats water only as you use it, so you get endless hot water instead of running out partway through a shower, and it takes up a fraction of the space a tank does. It costs more upfront than a like-for-like tank swap, and a contractor will need to check your gas line and venting can support it before you commit. If your home loses power during a winter storm, know that a gas tankless unit still needs electricity to run its ignition, so it won't work without power either.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, which means no more running out during back-to-back showers. Installation usually means new venting sized for the unit, since tankless heaters vent differently than a tank does, and often an upgraded gas line to supply the higher burner output. The unit itself mounts on a wall instead of sitting on the floor, so you get that floor space back. A contractor will need to look at your home's existing gas and venting setup to say what work that involves for your house.
