instant water heaters"Is it possible to drain a tankless water heater to prevent freeze damage when not in use?"
instant water heatersYes. Simply drain both lines 'to' and 'from' the unit. As long as there are no check valves in the way, that should drain the water from the unit. To guarantee that there is no water in the unit, we recommend two drain valves - one before and one after the unit - as well as blowing air through the water line.

"I would like to convert my natural gas tankless heater to be able to use LPG (propane) gas instead. Do you offer a conversion kit?"
Sorry, but we don't. Even if we could, we probably wouldn't, as in most cases it is not a good idea to convert one type of gas for another. Burners can be different, orifices, etc. Not only is the BTU rating different for these two gases, but also the heat of the flames and a number of other factors. We simply do not wish to sell ("profit from") something that might create a non-safe environment.

Takagi TK1S"I live in an area where it freezes, what can I do to protect the heater from freezing?"
Takagi T-K1S We recommend you use the TK-TV03 exhaust backflow prevention kit to prevent cold air from entering the vent and causing the heat exchanger to freeze.

information about tankless water heaters"If these units don't have a tank, how do they know when to turn on?"
education and frequently asked questions about instant water heaters These tankless water heaters have a flow switch built into them. When you turn on the hot side of a faucet the water begins moving. Once the water is traveling at minimum flow rate for the heater, the flow switch will turn on the gas or electricity.

instant water heaters"What's the difference between a conventional flue and a direct vent?"
instant water heatersA conventional flue is what most people are familiar with. It typically consists of a double-wall flue pipe going from the top of the heater through the roof, venting outside. The fixture draws its combustion air from the space around it (utility room, garage, hallway, etc.). A direct-vent unit on the other hand, both vents and draws its combustion air through a specially designed pipe from the outside via an adjacent wall.

"Your products specify the 'temp. rise' based on the GPM flow; what do you mean by this?"
Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.

questions about installing the TK-RB02"I received my tankless water heater recess box (Model TK-RB02) and it doesn't have any holes for the water, gas, or electric lines - so how do I connect the lines?"
answers about the gas, water, and electric holes that need to be drilled into the TK-RB02 tankless water heaterYou need to drill holes in the TK-RB02 recess box to accommodate the gas, water, and electric lines. There are three suggested places to drill the holes; these are illustrated in the diagram below. For the side entry option, just drill two holes for the water on one side and one hole on the other side for the gas as pictured in the diagram. For the bottom entry option, simply drill 3 holes in the bottom of the TK-RB02. There is also a back entry option where you drill 3 holes in through the back as shown in the diagram.

information about saving money"Will a tankless water heater save me money on my utility bills?"
education and frequently asked questions about bill savings Yes, however, the amount of savings will depend on the type of fuel used to heat the water. Usually electricity is more expensive than propane, and propane is usually more expensive than natural gas. In most cases you and the environmemnt will benefit from a tankless water heater.
