Frequently Asked Questions

While small countertop kettles are plug-and-play, tankless water heaters and larger tank-based systems often require a dedicated electrical circuit and professional plumbing to ensure safety and compliance with local building codes.
Tankless systems heat water on demand, eliminating the energy used to maintain water temperature in a tank. However, they often require higher wattage, which may necessitate electrical panel upgrades.
110V units are generally suited for low-demand areas like a single sink or a small RV, while 240V units provide significantly more heating power and are capable of supporting multiple fixtures.
