These units are made by one of the biggest names in water heaters - American Water Heating Company. Hence Titan tankless waterheaters have a lot going for them. American build out of their HQ in Johnson City, Tennessee, making all their products US built, and their headquarters is centrally located for getting products out to customers all over the States.
The Tiny Titan is one of those tankless hot water heaters designed for a very specific purpose. It is very small and can be installed just about any place. For example, it fits nicely in the utility room or is perfect for hot water in that new bathroom that is taking too much hot water from your tank.
Of course one of the great things about instant hot water heaters is that you never run short of hot water. These Tiny Titans are not designed to replace the whole hot water system for a house (though there are on demand hot water heaters that can do this job).
If you need a boost to your heat in one or another area of your home hot water system, something like the Titan might be just the job. They also come with the reassurance of the American commitment to quality and innovative engineering.
