• A post-installation inspection will be performed by HELCO to ensure your system was installed to HELCO's stringent standards.

Safety Notice!

In using hot water producted by any kind of heating system, especially a solar system, basic safety precautions should be followed. HELCO recommends that you always turn on the cold water faucet first, and then slowly add hot water until the desired temperature is reached.
