Invented for Life

Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the FVSTR: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink and double sink.

as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink

as a buffer installed in-line with tankless water heaters that experience intermittent cold water

known as ‘cold water sandwiching’. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.
