How do I Heat an Outbuilding With a Rechargeable Battery?

Outbuildings often lack a connection to the main building's power supply. If there are materials housed in the outbuilding that are susceptible to freezing, it may be necessary to add a heater to the building. If the outbuilding lacks an electrical system, an electric heater may be used if it is plugged into a power inverter connected to a rechargeable battery (such as a deep-cycle lead-acid battery).

Things You'll Need

  • Power inverter (minimum 1750 Watts continuous power)
  • Lead-acid battery
  • Electric heater (power not exceeding 1500 Watts)
