What to Look For When Buying a New Water Heater

If you need to replace an old or failing water heating system, or are ready to upgrade, we recommend that you:

1. Decide What Size You Need.

If your current water heater meets your needs most of the time, you can probably replace it with one the same size. Your contractor can help you decide if a larger model is necessary.

2. Choose the Best Fit for Your Hot Water Needs.

High efficiency water heaters often require direct venting outside. Tankless water heaters require a certain amount of gas pressure to operate. Your installer can determine which models are a good fit for your home and which models are eligible for DCSEU rebates.

3. Get a Rebate.

DCSEU rebates help offset the increased cost of high-efficiency water heaters.
