Takagi tk1"I live in an area where it freezes, what can I do to protect the heater from freezing?"
Takagi t-k1 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.

"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.

instant water heaters"If these units don't have a tank, how do they know when to turn on?"
instant water heatersThese 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.

instant water heaters"Will an instantaneous water heater save me money on my utility bills?"
instant water heatersYes, in most applications you will see a savings. There are some variables that could reduce the amount you save. One example is you will not run out of hot water, so longer showers could cut into your savings. Also, the cost of electricity, propane and natural gas in your area will affect the amount of money saved. The higher the cost for the energy type used to heat your water, the quicker you will recover the higher initial cost of installing a tankless versus tank style water heater.

Positives:

    You will never run out of hot water. "You want an hour long shower? No problem!"
    Electric units can be installed at the point of use.
    You're not paying energy costs to heat water 24 hours a day.
    They're easy to install.
    Our electric units don't require a T&P valve. (No tank!)
    Installing a tankless water heater will indeed be a bonus to the environment (why should we choose wastefulness when we're talking about finite natural resources)?

Negatives:

    They all need a minimum flow rate & pressure to turn on.
    The faster water flows through them, the lower the temperature rise. So,if you expect to take a shower while the clothes washer is running, you will need to select a unit sized to your hot water flow requirements. (Gas units handle this a little better than electric models)
    Electric units need heavy gauge wire. Example: the 9.5kw must have 8ga wire and a 50amp breaker.
    Gas units need a much larger, special flue pipe and larger gas supply than a conventional water heater.
    At times they can produce very hot water. It's easier to get scalded.
    Gas units are more complicated than a conventional water heater.
    With some brands, parts are hard to find (not a negative if you originally purchase from us, as we like to carry parts for the units that we sell).

Summary:
Tankless water heaters have their place. They're not "the answer" to every hot water need, but if they're used correctly they can be the solution to many of them.

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.

Why buy Takagi from us?"There are many companies selling all kinds of tankless water heaters. Why should I buy a Takagi instantaneous gas water heater from you rather than elsewhere?"
Our reputation is impecabbleWe are a large, reputable company that was here yesterday and we will be here tomorrow. We are often copied, but we don't believe that any one can match our service and certainly our base of satisfied customers is larger than any Internet plumbing supplier since 1995. We sell 1000's of other quality plumbing products as well, so you can rest assured that we know plumbing products. We are a very stable and reputable company. We love to sell what we believe in, and we definitely believe in Takagi.

Why buy Takagi from us?"Can I replace my existing tank type water heater with a tankless water heater?"
Our reputation is impecabbleYes, but there are specific requirements that will need to be addressed. Gas units will require a larger, special vent pipe and a larger gas supply line that not only will supply the water heater, but all other appliances on that gas pipe run. Electric units will require larger gauge wire and breakers than most tank type water heaters.

questions about tankless water heaters "Is the Hot Water Heater Scale Inhibitor System's active ingredient safe?"
answers about hot water heater scale inhibitor Yes! All ingredients used are 100% pure food grade materials. They are approved by the USDA and meet purity requirements as a food additive by the World Health Organization.

questions about hot water heater scale inhibitor "What are the best reasons to install a Scale Inhibitor System?"
answers about tankless water heaters The system inhibits scale build-up and protects the piping from corrosion, which helps maintain efficiency and extends the life of the system.

questions about hot water heater scale inhibitor "What happens if you don't change cartridges often enough on the Scale Inhibitor System?"
answers about tankless water heaters The original water condition and problem will reappear. Hardness will begin to build up again, which you want to avoid.

questions about tankless water heaters "How does the Hot Water Heater Scale Inhibitor System prevent corrosion?"
answers about tankless water heaters It forms a thin protective layer on the inside of pipes and metal parts. This film or layer is microscopic in thickness and will not build up over time.

questions about tankless water heaters "Will the Hot Water Heater Scale Inhibitor System change the taste or odor of water?"
answers about tankless water heaters No. The active ingredient is colorless, tasteless, and odorless when used as recommended.

Help save our environment by saving energy.
Stand-by heat loss wastes a LOT of energy.
Installing tankless water heaters saves
energy, as well as your pocket book in the
long run. Think future! Think green.
Think Tankless!
