Learn about Eccotemp Tankless Water Heaters

Our Water Heaters

Eccotemp tankless water heaters, also called instantaneous, continuous flow, inline, flash, on-demand or instant-on water heaters, are also available and gaining in popularity. These water heaters instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil.

Tankless heaters are often installed throughout a household at more than one point-of-use (POU), far from the central water heater, or larger models may still be used to provide all the hot water requirements for an entire house. The main advantages of Eccotemp tankless water heaters are a continuous flow of hot water and energy savings (as compared to a limited flow of continuously heating hot water from conventional tank water heaters).

How Eccotemp tankless water heaters work

When there is a demand for hot water (e.g. a hot water tap is opened for a sink, shower, tub, or washing machine) the tankless water heater's water flow turbine senses the flow and starts the heating process. The water flow turbine sends a signal to the control board which looks at multiple factors: incoming water temperature, desired water temperature as set on the temperature controller, and the calculated difference between the two temperatures. Depending on the calculated incoming and desired water temperatures, the gas or electric flow into the burner assembly is modulated and the electronic ignition sequence begins. Water is heated to the desired temperature as it circulates through the copper heat exchanger providing continuous hot water. When the hot water tap is turned off, the tankless water heater shuts down and is placed in a standby mode pending the next call for hot water.


Advantages to Owning an Eccotemp Tankless Water Heater

There are certain advantages to Eccotemp tankless water heaters :


  1. Long term energy savings: Although a tankless water heater might cost more initially it may result in both energy and cost savings in the long term. As water is heated only when it is needed, there is no storage of hot water. With a tank, water is kept warm all day even if it never gets used and heat loss through the tank walls will result in a continual energy drain. Even in homes or buildings with a high demand for hot water, a tankless water heater may provide some level of savings. In a typical home these savings are quite substantial. If instant hot water at the taps at limited hours is a priority, a recirculation system similar to those in the tank-type systems can be accommodated by using an aquastat and timer in order to decrease the added heat loss from the recirculation system. It has to be said though that if the storage tank is highly-insulated —a few tanks are available with excellent levels such as 100 mm or more polyurethane foam —the savings become minimal. For one consumer-grade electric storage water heater, the surface temperature was less than 1 °C higher than the air temperature.
  2. Unlimited hot water: As water is heated while passing through the system an unlimited supply of hot water is available with a tankless water heater. Although flow rate will determine the amount of hot water that can be generated at one time it can be generated indefinitely. However, this can also be a disadvantage as running out of hot water self-limits use while a tankless heater has no such limit.
  3. Less physical space: Most Eccotemp tankless water heaters can be mounted on a wall or even internally in a building's structure. This means less physical space has to be dedicated to heating water. Even systems that can't be mounted on walls take up less space than a tank-type water heater.
  4. Reduced risk of water damage: No stored water means there is no risk of water damage from a tank failure or rupture, although the risk of water damage from a pipe or fitting failure remains. Improper piping in either the hot or cold water lines to the tankless water heater can result in water damage though.
  5. Temperature compensation: A temperature compensating valve tends to eliminate the issue where the temperature and pressure from tankless heaters decrease during continuous use. Most new generation Eccotemp tankless water heaters stabilize water pressure and temperature by a bypass valve and a mixing valve which is incorporated in the unit. Modern Tankless are not inversely proportional, because they will regulate the amount of water that is created and discharged, therefore stabilizing water temperature by utilizing a flow control valve. Flow speed is not the issue, but change in temperature is the important issue to address. The wider the temperature rise, the less flow you receive from the unit. The smaller the temperature rise, the more flow you receive. The flow control valve in conjunction with thermistors, maintains a stable temperature throughout the use of the unit.
  6. Safety: Eccotemp tankless water heaters can precisely control the temperature of the treated water, which means dangerous temperature levels and spikes are no longer a problem.

How to Select the Right Size Tankless Water Heater

Tankless water heaters are rated by the maximum temperature rise possible at a given flow rate. Therefore, to size a demand water heater, you need to determine the flow rate and the temperature rise you’ll need for its application (whole house or a remote application, such as just a bathroom) in your home. It is important to note that you should never try and save money by under-sizing your tankless water heater.

Step 1:

Determine the maximum number of devices you want to run and their total flow rate. Then, add up their flow rates (gallons per minute). This is the desired flow rate you’ll want for the demand water heater. For example, let’s say you expect to simultaneously run a hot water faucet with a flow rate of 0.75 gallons per minute and a shower head with a flow rate of 2.6 gallons per minute. The flow rate through the demand water heater would need to be at least 3.26 gallons per minute. To reduce flow rates, install low-flow water fixtures.

Step 2:

Determine required temperature rise. To determine temperature rise, subtract the incoming water temperature from the desired output temperature. Unless you know otherwise, assume that the incoming water temperature is 50°F (By using a low temperature assumption you ensure that you will not under size your tankless unit. If you live in a warm climate your water temperature will likely be much higher.) For most uses, you’ll want your water heated to around 105–115°. In this example, you’d need a demand water heater that produces a temperature rise of 55°.

Step 3:

Sizing Example: An average shower will be between 104–106° and uses 2.6 gallons of water. Assuming your water temperature is 40° coming into your home, and you want to produce enough hot water to run 2 showers at the same time, what temperature rise would you need to produce to accomplish this? Answer: You’ll need to raise the incoming water temperature from 40 degrees to 105. You’ll need to be able to heat at least 5.2 gallons of water. So you’ll need a tankless water heater that can produce at least a 60 degree rise in temperature at 5.2 gallons per minute.

Flow Rates

How much hot water do you need at one time? Do you need to run 2 showers at the same time or maybe a shower and a couple sinks? The chart below shows the range of water usage range and average water temperatures for various fixtures. We suggest using 2.5 gpm for a shower and 1.0 gpm for a bathroom as a reference point in determining your total simultaneous water needs.



FIXTURE

AVERAGE FLOW GPM

AVERAGE TEMPERATURE

Tub
4.0 GPM
102°F
Shower
2.5 – 3.0 GPM
104°F
Washing Machine
2.0 GPM
120°F
Dishwasher
1.5 GPM
110°F
Kitchen Sink
1.5 GPM
110°F

For example, if you are running 2 showers at the same time, you will need 5 gallons of hot water per minute from the tankless water heater. If you were running a shower and the washing machine at the same time, you would need 4.5 gallons per minute from the water heater. In either of these situations, you will want to size the unit that meets or exceeds how much hot water you need at the same time.



Note:
tankless water heaters are intended to heat potable (drinking) water only and the inlet water to a tankless unit should not be pre-heated.

Other Sizing Notes

Gas tankless water heaters are able to produce a larger temperature rise per gpm than electric models. Most demand water heaters are rated for a variety of inlet temperatures. Typically, a 70°F water temperature rise is possible at a flow rate of 5 gallons per minute through gas-fired demand water heaters and 2 gallons per minute through electric water heaters. Faster flow rates or cooler inlet temperatures can sometimes reduce the water temperature at the most distant faucet.

Winterizing your Tankless Water Heater 

Cold Weather is coming. Is your Eccotemp tankless water heater ready? We are here to help!

How to winterize a Tankless Water Heater

If you have a tankless water heater that is not used for a longer period of time, and the place where you live is subjected to the freezing temperatures, it is very important to protect the unit during this cold winter time. Use the step-by-step guide below to learn how to winterize tankless water heater and avoid failure of the unit.

Many new tankless water heaters with the advanced technology and features like protection against freezing cold can be found today from the main manufacturers, like Rheem, AO Smith, Rinnai, Paloma... and during the winter time they can protect the system from freezing down to -30 F or even lower. But, don't rely on such a great feature.

Why?

These units are using an electric power as a protection system, so if there is a power outage, guess what... your tankless unit will fail.

This is why you should learn how to winterize tankless water heater during the cold days.

Note: Almost every manufacturer of tankless heaters specifies that the heater must not be installed in the area where the temperature can reach 36 F or lower. If precautions are not taken, like draining, the damage to the tankless unit and its components will not be covered under the warranty. Adding the anti-freeze solution is also not recommended as it can cause the damage to the heater's components.

This is especially important if the tankless water heater is installed in places like cabins, garages, and if you are absent for a long time.

Step-by-step guide about winterizing

One of the main steps in how to winterize the unattended tankless heater is to drain and unplug the unit. If there is no water in the heater's pipes and especially in the heat exchanger, the unit will not be damaged due to the freezing conditions.

So, how to prepare the heater for winter?

  • First you have to turn the electrical power and gas supply off. Turn the gas off by using the main valve on the gas supply line, and for the electricity unplug the power supply cord. If the unit has the display at the front of the unit, it should be black.
  • If your tankless heater was working, you still have some hot water inside the unit. Wait for a while until it cools down.
  • Shut off the water supply on the main shut-off valve.
  • Open the taps so the system can drain and release the pressure from the plumbing system.
  • Disconnect incoming and outgoing water pipes from the tankless heater.
  • Remove the inlet water filter.
  • Use the bucket to collect the residual water. Make sure that it fully drains from the system.

Now the water heater doesn't contain any water and it is fully winterized. Some manufacturers recommend using the air compressor, blow short bursts of air through the inlet connection to make sure there is no water left inside the heater.

Which Unit Should I Use For My Radiant/Floor Heating Needs?

Did You Know Electric Tankless Water Heaters Are Great For Radiant/Floor Heating?

Radiant in-floor heating is a comfortable way to experience heat evenly throughout a home. Interestingly, with radiant surfaces everywhere, air temperature in a house can actually be lower than what you think is comfortable, and you will still feel warm.

A well-designed hydronic heating system can be very economical in terms of energy use. This is especially true when a high-efficiency tankless water heater is used as the main hot water source. For even greater savings, it's possible to install a solar thermal system that will allow the sun to do some of the water-heating work.

The system with a tankless water heater will also be much more responsive, have unlimited supply of hot water and clean water running through the floor heating pipes without sediments and other mineral build-ups.


Luxury Bath Room


A tankless hot water heater is ideal for this application since there is no water to be kept hot at all times. The water is heated only when needed or requested. Water is fed through a super efficient heat exchanger and then heated. The water temperature is heated to the selected temperature setting precisely by adjusting the gas burner's flame to the desired temperature. Water temperature sensors monitor the water temperature and the tankless water heater's computer modulates the burner. This means that the water is never over heated or under heated.

Regardless of the heat dissipating rate of the pipes the water is heated to the set temperature instantly due to the ability of the tankless water heater to vary its heating flame and power. The result is a very responsive system that can quickly replenish the lost heat in the pipes and therefore quickly heat the floor in case of floor heating application.

This heating system uses the entire finished floor as a giant radiator. Hot water is pumped through plastic tubing installed beneath the finished floor surface. A hydronic radiant floor can be installed beneath tile or wood; it can also be embedded in a poured concrete slab. It's not a wise choice beneath wall-to-wall carpet because the carpet doesn't conduct heat very well.

The traditional tank boiler is not able to do this because it cannot vary its flame intensity. A properly designed and installed system provides then comfortable and efficient floor heating regulated by a standard thermostat inside the home. Other than providing fast heating response the hydronic system enables large continued energy savings for years lowering significantly the operating cost of floor heating.

Venting

According to ANSI code, gas tankless water heaters normally require stainless steel, category II/III vent pipe. This is due to the fact that gas tankless water heaters actually burn at a higher BTU rating.

As such, the gas is extremely hot when it leaves the water heater, but cools quickly. This cooling process results in acidic condensation which could eat through regular galvanized pipe.

EccoTemp Systems recommend using Z-Flex vent pipe. Both of the i12 and FVI12 models use 2.5" single walled venting while the 45 Series uses 4" single walled venting.


Installation requirements: Horizontal Termination

We always recommend a horizontal installation when it is possible. It requires less pipe and as such, less expensive. When doing a horizontal run, your maximum lengths are as follows:

1 elbow: 47' 6"

2 elbows: 42' 6"

3 elbows: 37' 6"

Each elbow is equivalent to 5' of straight pipe.


Installation requirements: Vertical Termination

When installing a vertical vent stack, you will need the following pieces:

Universal appliance adapter

Drainpipe for condensation

Flashing

Storm collar

Rain cap

Straight pipe


NOTE: A TERMINATION HOOD OR STRAIGHT PIPE SECTION MUST BE EQUIPPED WITH A DAMPER/BACKFLOW PREVENTER IS MANDATORY TO ENSURE THAT FREEZING AIR DOES NOT COME BACK DOWN THROUGH THE VENT STACK. 

THIS MAY CAUSE FREEZE DAMAGE INTERNALLY IN THE WATER HEATER AND IS NOT COVERED UNDER WARRANTY.

Gas Pipe System Sizing



Determining The Required Meter and Regulator size

Find the BTU requirement of each appliance in the home. In our example above, we have the following: 199,900 BTU Tankless, a 75,000 BTU Furnace, a 55,000 BTU Range, a 25,000 BTU Dryer, and a 40,000 BTU Gas Log Fireplace. The sum of these appliances is 394,900 BTU. Since most gas regulators and meters are rated in Cubic Feet per Hour, we need to convert the BTU calculation to ensure they are sized correctly. Divide total BTU by 1,024 to get the estimated Cubic Feet per Hour (CFH) requirement for the meter and regulator; 386 CFH in our example.

If the water heater was a typical tank type at 40,000 BTU, then the overall system requirement would have been just 235,000 BTU with a meter and regulator rated at 235 Cubic Feet per Hour. A typical household meter and regulator is commonly rated at 250 Cubic Feet per Hour. As you can see that in the example above, when you change the water heater to a tankless, the existing regulator and meter would be potentially undersized. It is important to have a properly sized meter and regulator on the system; otherwise, the appliances on the system could experience operational issues. The local gas utility can provide more information on upgrading the meter and regulator for the home.

Hybrid pressure systems, with a 2 psi static pressure with regulators at each appliance, are sized differently than in this example. Consult your local gas supplier or the National Fuel Gas Code in regards to these type systems.


Pipe Sizing Methods

There are two basic pipe sizing methods: longest length and branch length. Proper sizing will allow the system to maintain the required minimum pressure drop.

In the longest length method, the pipe size of each section should be determined by using the longest length of piping from the point of delivery, the gas meter or regulator, to the most remote outlet and the load of the section.

In the branch length method, the pipe size of each section of the longest pipe run, from the point of delivery to the most remote outlet, should be determined by the longest run of piping and the load of the section. The pipe size of each section of branch piping should be determined using the length of piping from the point of delivery to the most remote outlet in each branch and the load of the section. Branch length sizing is the most common method.

Determining Pipe Size by Length and Capacity

We will need to calculate the total load of the system and each branch. In our sample system, Figure 1, measure and add the lengths of pipes at each section. Total the BTU of the appliances for each branch line and the main trunk line back to the gas meter. Select the appropriate sized gas line based on length, BTU capacity, and pressure drop from Table 2, Table 3, or Table 4.



You can see that, in a typical gas system, a tankless water heater with a capacity of 199,900 BTU will require a 1-inch pipe size for a 20 ft branch length (based on the 0.3 in w.c. pressure drop in Table 2). The same appliance would require just a ½” pipe size based on Table 4 the 3.0 in w.c. pressure drop.

A branch line is a pipe off the main line that feeds a group of appliances. In our example, we have two branch lines. The pipe size of the main pipe on the branch must be sized based on the total BTU of all the appliances on that branch line and pipe length.

The trunk line pipe is the main pipe from the meter/regulator that feeds the different branches. The trunk line must be sized based on the total BTU from each branch-line system or the sum of the total BTU of all the appliances on the system and pipe length.

Items such as elbows, tees, and valves are not included in these sample calculations. Their equivalent pipe length should be included when sizing gas systems. It is recommend that a licensed gas tradesman size, design, and install the gas system.


Pipe Sizing Formula and Factors

You can calculate the required inside diameter of the piping required for a specific appliance/system capacity and length.

Calculate Q by dividing the BTU capacity of the appliance(s) by 1,024.

To determine the allowable pressure drop, find the system static input gas pressure using a Manometer. Then, find the highest minimum gas pressure from all the appliances, usually listed on the appliances rating label. Subtract the highest minimum gas pressure from the static input gas pressure to get the difference. For example, the input static pressure is 7 in. w.c.; the highest minimum pressure is 6 in. w.c.; leaving a difference of 1 in. w.c. In this example the system can have a .5 in. w.c. pressure drop based on Table 3. If the input pressure was 9 in. w.c., in this example, then a 3.0 in. w.c. pressure drop based on Table 4 would be allowable.

GAS WARNING

Gas Hose Adapter Warning

The Eccotemp L5 and Eccotemp L10 model heaters have a 1/2" to 3/8" adapter in the hardware pack for attachment of the LP hose to the heater.

This adapter must be installed with thread sealant , a spool of pipe tape which is included with the tankless water heater is recommended for use.

Multiple wraps of pipe tape may be necessary to assure complete seal.

Always check for gas leaks before using the heater.

Before attempting to light the water heater make sure to look and smell for gas leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak that must be corrected. When smelling to detect a gas leak, be sure to sniff near the floor also.

SHIPPING DAMAGE

If an item is damaged in transit, please contact us immediately upon your receipt of said package. If there is obvious visible damage to the package, please document it with photos or video if possible. These will be requested to help settle any claim with the carrier.

Please provide the order number, the damaged or defective item, and your name, email address, shipping address, and phone number.
