For more complex electrical projects, it’s often most efficient and cost-effective to hire an electrician rather than trying to figure it out yourself (and risking electrical problems). Electricians know exactly what a project requires, and can often find supplies or parts for cheaper than the average homeowner. That can save money compared to going it alone.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

• Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

• Get at least three quotes for service to find the best deal.

• Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

• If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.
