Tankless Water Heaters

A tankless, or “on-demand” water heater is a space and energy-saving alternative to storage type water heaters. Tankless water heaters only turn on when the hot water tap is opened and the flow is detected. Since there’s no need to keep a tank full of water heated at all times, no energy is wasted, making tankless hot water heaters extremely energy efficient, allowing for the installation to pay off in a matter of a few years.
