Replacing a gas water heater yourself might seem straightforward, but the real danger is in the venting. A bad vent can push carbon monoxide back into your home, and that risk is harder to catch than a gas leak. Many homeowners use the swap as a chance to upgrade to a heat pump water heater, which cuts energy use and removes combustion safety concerns entirely. If you do the work yourself, check local permit rules and have an inspector verify the vent and gas connections. For those considering a switch, heat pump models often qualify for rebates and tax credits that lower the upfront cost, and they can reduce monthly utility bills compared to gas units.
