An undersink water heater is a small unit that provides instant warm water. Undersink water heaters are a popular choice because warm water can be obtained by the user almost instantly. Unlike a regular water heater, undersink water heaters do not require long pipes, and this allows the unit to deliver instantly, perfect for when warm water is needed at the point of use, for example, a sink, garage, office or en suite.
Alongside instant warm water, undersink water heaters come with many other advantages. They are often a top pick due to their compact size, which allows these units to be small enough to fit in a cupboard directly where the outlet is, and can be installed wall-mounted or free-standing.
