I recently had my old 50 Gallon storage tank replaced with Bosch T9800 Tankless water heater. This is indeed a great product and has a lot to offer as far as the hot water supply is concerned which is unlimited. This is my first experience using a tankless and I am glad that I chose Bosch brand. - Todd From Markham

A friend of mine recommended me to buy Bosch brand tankless water heater as I was already looking for a tankless and did a lot of research. Eventually I ended up buying Bosch T9800 SE 166 which was a perfect match for my requirement. I must say that Bosch brand appliances are very much reliable and innovative. - Daniel From Stoney Creek
