Customers say's :
Takagi TK-04-OS

This tankless heater came recommended to me by three other contractors I know.

They did not dissappoint me. the unit ,once installed is flawless and workd perfectly.

I have nothing bad to say of this unit at all !!

I will say that it would probably be best if this unit is installed by a professional.

First it doesn't void your warranty and second it is not just a plug and play item.

Once installed you will love it.

Great product and service
I do not write many reviews but felt the need to praise this product and company. The 1st thing to understand is this technology is relatively new as opposed to a conventional tank water heater. With that said here is my experience. I had this models predecessor installed in 2008 a t-k3 along with the appropriate filters in front of it to protect it from hard water deposits a MUST ! Unit worked flawlessly for 5 years, I had the annual service performed, descalling and cleaning the heater core and filters . I began to have some trouble with the unit then not turning on once in a while, I called the Takagi help desk and they sent me the needed parts igniter and technical instructions at no charge. I performed the service replaced the gaskets and the unit worked well until 2014 before acting up again. When I pulled the cover I noticed that there was corrosion occurring as a result of tiny water leaks, I called the Takagi help desk and they totally supported the now 7-8 year old...
