What a Brockton winter asks of a water heater
Winter nights here average 23°F from December through February, and homes need heat October through May, eight months of the year. A water heater works through all of it, alongside the furnace, without a season off.
Power is part of the picture too. About 10% of Massachusetts households went at least 24 hours without power in 2024, and the county has logged 61 winter storms and 346 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition will not light until the power is back. Whichever type goes in, it has to meet the federal minimum efficiency rule, and that minimum is set by the tank's size and how the household draws hot water, so it is not the same number for every heater.

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?
- The clearest sign is age. Most tank water heaters have a working life span, and once a heater is well past its early years the tank itself starts to weaken from the inside. Rusty water, a tank that's noisy when it heats, or water pooling around the base all point to the same thing. If the heater is running out of hot water faster than it used to, that's the burner or element losing ground, not something a repair usually fixes for good. A leak from the tank itself means replacement, not repair, since the tank can't be patched.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your water heater being broken. A tankless unit heats water as it flows through, so you don't run out of hot water partway through a shower, and it doesn't sit there heating a tank of water all day when nobody's using it. It costs more upfront than a tank of the same capacity. If your current tank is still working fine, that's a reason to wait, not a reason to switch. A contractor can walk through what your household's hot water use actually looks like and whether tankless fits it.
- What changes when you install a tankless water heater?
- The biggest change is space. A tankless unit mounts on the wall and takes up a fraction of the floor space a tank does, since there's no tank to store hot water in. Gas tankless units usually need a larger gas line and a different vent than the tank they replace, because they draw more gas when they're running. Electric tankless units often need more electrical capacity than a home has for the panel to handle them. None of this is a small swap, so a contractor needs to look at the gas line, the vent, and the electrical panel before pricing the switch.
