Insulate your water heater tank with an insulating blanket if you still use that system. You can save half a ton of carbon dioxide emissions escaping every year by simply doing this. You’ll save money big time too.
Don’t stop with the tank though, insulate the pipes leaving the tank as well. Usually the hot water has to heat the cold pipes before it is able to provide hot water at the sink faucet, which may be some distance from the tank.
The better insulated the whole system is, the more you save both in cash and reduced CO2 emissions.
