We have flexible payment options when you want to buy, including Visa, MasterCard or your personal or business check. You can purchase a water heater and we will deliver the tank to your home or business. You can have your licensed contractor install the heater, or we can arrange to have one of our trained professionals install it for you. We will provide you with a free estimate of the installation cost. Email us at CustomerService@SmartHotWater.com to request your free estimate today. The choice is yours! If you ever need repairs or replacement, give us a call and we will dispatch our contractor to you!
