Tankless Water Heater: Twin Power

Takless Water Heater: Twin Power
  Twin Titan: The Power Of Two
By combining two units in a parallel circuit you are able to effectively double the heating power of your tankless water heating system. This method is ideal in colder climates, where the incoming water temperature is below 50°F. Diagram is for illustration purposes. Please consult with your local installer for requirements.

Who should use the Twin Titan Configuration?
This setup is ideal for homes in the Northern States, where the incoming water temperature may be below 50° F at certain times of the year. Homes with high demand for hot water, such as water jet type showers, may also benefit from this configuration.

Why use two units? Why not just one large tankless water heater?
One N-120 requires a 60 AMP breaker. This is the largest allowed by the NEC (National Electric Code) for this type of appliance in a residential home. This limitation imposed by the NEC determines how the units are built.

What about your competitors, they sell one large unit?
Actually, they sell one box with two units inside. Many companies are not very up front about this. They disguise two units in one box and market it as a "single" large unit. But just take a look at their wiring diagram (if you can find it) and it will become obvious that you are actually connecting two units, with two runs of wires, and two individual breakers for each of the two unit inside the "one" box.

So, which is better, a Twin Titan setup? Or a "single" box housing two units inside?
Let's see:

  • The Twin Titan setup provides Redundancy, a backup plan, if you will. In a Twin Titan setup, if one unit needed to be serviced, you would be able to remove that unit and send it in for service. All the while, the other Titan will still be heating your water. In a single box housing two units, you will need to completely remove the entire box and send it in for repair, leaving you cold.
  • The Twin Titan configuration has approximately 25% higher heating capacity than the largest "single" box from the competition.
  • Our Twin Titan configuration costs about 1/3 (one-third) less than the competition's"single" box.
  • The Titan has a proven and established track record. Since 1986 our units have been heating the water in homes across the US and abroad.

Tankless Water Heater Setup: Parallel Vs.Series
There are a number of advantages the parallel setup has over the series setup (sequence):

  • Increased Flow Rate - By installing the tankless water heaters in a parallel system you will effectively double the available flow rate, as the water runs into each heater independently.
  • Redundancy: In a parallel setup, if one of the tankless water heaters ever needed to be removed for servicing, it may be taken out of the system and still leave the other heater in place, fully functional. Granted, you will not have the same capacity for hot water, but you will have hot water nonetheless.
  • Increased Service Life: In the parallel setup, both tankless water heaters receive cold water directly from the supply line. In a series setup, one of the heaters would receive hot or warm water from the first unit. This second unit may not be able to cool itself effectively as the water it is receiving may already hot/warm.
  • Heating Capacity: Because the water supply is divided into two, each of the tankless water heaters in a parallel setup gets only half as much water, therefore are able to provide virtually twice as much heat. Hence, the parallel tankless water heater setup is able to provide as much heating capacity as the series setup, plus all the added advantages outlined above.

For increased heating capacity and flow rate, a parallel tankless water heating setup really is the recommended way to go.

I live in the northern part of the country. Can I still use just one Titan?
Absolutely, you can still use one single Titan. However, please make note of the following, determining and understanding the following factors:

  • Your incoming water temperature
  • The water flow of your showerhead/faucet
  • The Titan SCR2 N-120 will raise your water temperature 50° at a rate of 2 GPM (Gallons Per Minute)

Now, to illustrate. Let's say that your incoming water temperature is 45°, and your showerhead has a flow rate of 2.0GPM, your final water temperature will be 95°, just bit warm. So what can we do? You could replace your showerhead for a more efficient model, of say, 1.5GMP. At this flow rate, the Titan will raise the temperature of your water 66°, providing you with a final water temperature of approximately 111°. Studies have shown that a comfortably warm shower is taken at a temperature of 102°-105°F, temperatures above that are generally considered too hot for comfort.

How's the performance of an efficient showerhead?
Keep in mind that a low flow showerhead does NOT mean wimpy showers. As a matter of fact, in most cases, these showerheads provide more pressure, for a more vigorous shower than regular showerheads using double the amount of water. Special mechanisms inside these units allow for the increased pressure, resulting in a satisfying shower.

Hmm, I still have another couple of questions. Whom can I ask?
