Tankless vs Traditional Water Heaters
Installing Gas vs. Electric Heaters
According to the Department of Energy, water heating is the second highest utility expense for homeowners. Choosing the right water heater can make a big difference in monthly expenses.
For many homeowners, the type of water heater they choose will largely depend on the energy source available to them in their home and in their area. Unfortunately, that means some homeowners cannot choose between gas or electric.
Electric tankless hot water heaters are much easier and less expensive to install than gas heaters. Electric systems are typically about one third the size of gas systems. Since there is no gas combustion, electric systems don’t require ventilation so homeowners have more options and flexibility as to where they want to install them.
If you plan to hire a professional to install your system, consider the following:
- Ask for local references.
- Research potential contractors with your local Better Business Bureau.
- Request cost estimates in writing.
- Check if the contractor will obtain the required permits and understands local codes.

Hot water heater installation can be a significant line item on any home maintenance budget. In today’s world with easy access to how-to guides and instructional videos online, many DIY inclined homeowners may choose to install their own electric tankless hot water heaters in an attempt to save money.
In general, tankless water heaters are safer than storage tank water heaters. However, the vast majority of homeowners trust verified experts to install their tankless hot water heaters because incorrect installation can pose significant safety risks in the home. If your tankless systems runs on natural gas, as with any gas system, there is potential for carbon monoxide leaking if installed incorrectly.
Most communities in Washington state require that homeowners obtain a permit before installing hot water heaters. Every few years water heater codes change to adapt to new standards, technologies and safety measures. It is prudent to trust industry experts with installing your water heater not only for safety reasons but also to ensure compliance with current laws and regulations.
