Electric Mini Tank Water Heaters

Electric Mini Tank Water Heaters — Hot Water Right Where You Need It

There's a specific frustration that comes with waiting 90 seconds for hot water at a bathroom sink that's far from the main heater. It's not a big deal — until it is, every single morning. Mini tank water heaters solve exactly that problem.

These units install directly under the sink or in a closet, store a small amount of pre-heated water, and deliver it instantly. No tankless flow rate minimums, no complex wiring — just plug into a standard 120V outlet and you're done.

The Camplux 6.5-gallon mini tank is the right call for a bathroom or kitchen with moderate use — enough capacity for handwashing, dishwashing, and a short rinse without running cold. The 4-gallon version fits tighter spaces and works well for a single sink or a small office washroom. And the 10-gallon unit bridges the gap between point-of-use and a full water heater — useful for a garage, workshop, or secondary bathroom.

A few practical notes:

• All three models run on standard 120V — no electrical panel upgrade needed.
• Installation is straightforward enough for a confident DIYer, though a licensed plumber is recommended for supply line connections in Canada.
• These are storage tanks, not tankless — recovery time matters if you're drawing hot water continuously.
