No Hot Water? Try These DIY Fixes.

  • Make sure the unit has electricity.

    Both gas and electric tankless water heaters need electricity to run. Make sure your unit is hooked up to a 120-volt outlet. Also, check the electrical panel’s “water heater” breaker. You might just need to flip the switch back to “ON”.

  • Make sure the exhaust vent is clear.

    Gas tankless water heaters need an exhaust vent to get rid of toxins they produce. If something is blocking the exhaust vent, that could be the reason you’re not getting hot water.

  • Check the gas supply valve.

    Gas tankless water heaters have a valve (a handle/knob on the gas line leading to the unit) that controls the unit’s gas supply. Make sure it’s turned to the “ON” position.

Still not getting any hot water? You’ll need to call Global at (216) 797-1230 to find and fix the problem.
