T-M32 Mobius Tankless Water Heater

Q. "What type of vent do these tankless water heaters require?"
A. These tankless water heaters require Category III stainless steel vent only.

Q. "Why can't I install the Mobius T-M32 myself?"
A. The manufacturer states that this unit can only be purchased and installed by special factory-trained, skilled technicians who have taken an extensive learning course in the installation of this product. We can only sell this tankless water heater to qualified installers. There is no warranty if this specific model is not installed by a licensed, qualified contractor.

Q. "What is HRS35 copper?"
A. HRS35 copper is an alloy that is 99.5% pure copper with a .5% mixture of other elements. These other elements include small amounts of tin (Sn), cobalt (Co), zinc (Zn), nickel (Ni), and phosphorous (P). The mixture of these elements produces a stronger copper alloy that has increased durability and resistance to heat fatigue and out-performs standard copper while still maintaining its advantages.

Q. "Can I use PVC to vent this tankless water heater?"
A. No. The temperature of the exhaust is too high to safely use PVC as venting material. We never recommend PVC as venting even where the ideal exhaust temperatures would technically allow it due to a much higher incident of dangerous issues associated with PVC venting on poorly-maintained gas tankless water heaters.

Q. "There are many companies selling all kinds of tankless water heaters. Why should I buy a Takagi tankless gas water heater from you rather than elsewhere?"
A. We 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.

Q. "If these units don't have a tank, how do they know when to turn on?"
A. 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.

Q. "What's the difference between a conventional flue and a direct vent?"
A. A 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 vents and draws its combustion air through a specially designed pipe from the outside via an adjacent wall.

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

Q. "I noticed that this tankless water heater is designed for heavy duty commercial applications. Do you offer a tankless water heater that is designed for light commercial applications?"
A. Yes we do! The Takagi Mobius T-K3 is designed specifically for light commercial applications.

Q. "Will an instantaneous water heater save me money on my utility bills?"
A.In many applications you can 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 can 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!) - if code allows
Installing a tankless water heater can 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 maximum hot water flow requirements. (Gas units generally 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.

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

Q. "It sometimes drops below freezing where I live. Can I still install a Takagi tankless water heater outside?"
A. Takagi gas tankless water heaters are designed to be installed outdoors only in mild temperate climates. The factory-installed freeze protection device is rated for temperatures down to 5°F in a wind-free environment, so wind-chill factors must be taken into account when choosing whether or not to install a Takagi tankless water heater outdoors. If you are unsure if temperatures at your planned installation would work for an outdoor tankless water heater, we strongly recommend consulting with a trusted local professional.

Q. "What do I need to install these Takagi tankless water heaters outdoors?"
A. Outdoor-only Takagi tankless water heaters, such as the T-K4-OS or the T-KJr2-OS, require no additional venting components. Units that can be installed either indoors or outdoors, such as the T-M32 is designed to need only the addition of an outdoor vent cap or properly vented recess box in order to function in an outdoor installation. Please note that Takagi tankless water heaters, like most brands of water heaters, are designed to be installed outdoors only in mild temperate climates. As always, please consult with your installer or another trusted professional before installation.

Q. "What are the best reasons to install a Scale Inhibitor System?"
A. The system inhibits scale build-up and protects the piping from corrosion, which helps maintain efficiency and extends the life of the system.

Q. "What is siliphos?"
A. Siliphos is a water treatment compound; a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems and to prevent the build-up of scale in plumbing.

Q. "How does the Water Heater Scale Inhibitor System prevent corrosion?"
A. 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.

Q. "What happens if you don't change cartridges often enough on the Scale Inhibitor System?"
A. The original water condition and problem will reappear. Hardness will begin to build up again, which you want to avoid.

Q. "Is the Water Heater Scale Inhibitor System's active ingredient safe?"
A. 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.

Q. "Will the Water Heater Scale Inhibitor System change the taste or odor of water?"
A. No. The active ingredient is colorless, tasteless, and odorless when used as recommended.
