To "run on" something means to be operated on or driven by something, usually an energy source like electricity, gas, or so on. The speaker here is explaining that their heating systems run on (are operated on) gas. Ex: Electric cars are slowly replacing cars that run on gas. Ex: My house is old, so the heating system still runs on gas.
