The ECO 27 generates 92,128 BTUs using 27kW of power. This means that three forty amp breakers will be required to operate it. A range of 2.7 to 6.5 gallons per minute of hot water is plenty for most families of four or five. Temperature settings are adjustable in one-degree increments and self-modulating energy consumption saves electricity.
The first thing to decide when choosing your electric tankless water heater is whether you desire a whole house or a point-of-use heater. Point-of-use heaters are great for large houses with long plumbing lines, remodels or additions, appliance applications or remote sink locations. Whole house heaters provide all of your hot water needs from a central location.
These tankless water heater size calculations will determine how many kilowatts of heating capacity your tankless electric heater needs to provide. The electrical capacity of your home may limit the size of heater that you can operate. These calculations can be accurately done by a homeowner, but your retailer or installer will have more experience with the process.
When it comes to water or any type of liquid measurement, GPM refers to the gallons per minute. It measures exactly how much water moves through your appliance and may also be referred to as the flow rate. Certain appliances, like showers and washing machines, for example, require more water. But for the average household, the water heater should have a flow rate of about 9 gallons per minute.
They can save on energy bills in the long run, but the initial cost of a tankless water heater and its installation tends to be quite a bit higher than tank-style water heaters. Saving money on DIY installation is possible but not recommended in most cases. If upfront prices are a concern, considering a point-of-use heater as an alternative to a whole house heater, may be a viable solution.
Tankless water heaters are on-demand appliances. For large families, or families that place a high demand on hot water needs, this might be the most important reason to buy a tankless water heater. Hot water can always be generated instead of having to wait for an entire tank of water to heat up after a series of showers has depleted the supply.
Tank style water heaters have a life expectancy that tops out at about 15 years. With proper maintenance a tankless water heater can be relied on for up to 20. Although there are more parts that have the potential to fail, most parts are replaceable or repairable in contrast to a tank style water heater.
Primarily, tankless water heater pros and cons are issues regarding convenience. Saving money and space while providing energy efficient readiness is great. Upfront costs, maintenance needs and potential capacity limits need to be considered as cons.
Being energy efficient by simply using less energy is always good for the environment. Electric tankless water heaters have an advantage over gas burning heaters if the electricity used is generated from renewable sources. Many energy providers are moving in that direction as fossil fuel use is declining. In short, electric tankless water heaters are eco-friendly and becoming more so as technology progresses.
Under normal circumstances an electric tankless water heater with 20kW of power will meet all the hot water needs of a home with a family of three of four people. Hot water needs grow exponentially for larger sized families. For those homes, electric tankless water heaters are available in sizes using 34kW or more.
Whether you choose a point-of-use heater or a whole house heater, choosing a size is the same process. Normal maximum water flow needs, the number of water fixtures affected and temperature rise required will all need careful calculation. These calculations can be done with relative ease by a consumer. Retailers and installers, though, will be more experienced and can assist with the process.
The list of required steps needed to maintain an electric tankless water heater can look intimidating. The truth is that the maintenance tasks can be done in a matter of minutes after a little practice and having the right tools for the job.
Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save money. Here you'll find basic information about how they work, whether a tankless water heater might be right for your home, and what criteria to use when selecting the right model. Check out the Energy Saver 101: Water Heating infographic to learn if a tankless water heater is right for you, and our #AskEnergySaver discussion on water heating for more answers on efficient water heating.
Tankless water heaters heat water instantaneously without the use of a storage tank. When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater's output limits the flow rate.
Tankless water heaters avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a pilot light. This can sometimes offset the elimination of standby energy losses when compared to a storage water heater. In a gas-fired storage water heater, the pilot light heats the water in the tank so the energy isn't wasted.
The cost of operating a pilot light in a tankless water heater varies from model to model. Review the manufacturer's literature to determine how much gas the pilot light uses for the model you're considering. Look for models that have an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition device on some natural gas furnaces and kitchen ranges and ovens.
Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues, especially concerning the combustion of gas-fired water heaters. Therefore, it's best to have a qualified plumbing and heating contractor install your demand water heater. Do the following when selecting a contractor:
If you're determined to install your water heater yourself, first consult the manufacturer. Manufacturers usually have the necessary installation and instruction manuals. Also, contact your city or town for information about obtaining a permit, if necessary, and about local water heater installation codes.
After your demand water heater is properly installed and maintained, try some additional energy-saving options to help lower your water heating bills. Some energy-saving devices and systems are more cost-effective to install with the water heater.
While traditional water heaters remain the best choice for some, tankless models save space and can help reduce monthly heating bills. Before switching, shoppers should choose between a gas or electric model. High-end gas models are usually more powerful but are also more expensive and challenging to install.

Shoppers looking to buy the best tankless water heater for their homes should know that the process of finding one involves more than just determining whether it will heat sufficient water. The type, flow rate, and other features play an important role, too. Here are several key issues that will likely influence decision-making.
The total number of showers, tubs, sinks, and washing machines inside a house helps the homeowner determine the water heater size needed. A 1- or 2-bath home typically needs around 5 GPM, while a 3- or 4-bath home needs a 10 GPM unit.
Water supply temperature impacts GPM, meaning a model fitted in the southern U.S. would provide a higher GPM than one fitted in northern states. Also, the GPM of electric tankless water heaters is often secondary to power (given in kilowatts, or kW). This figure gives the energy used and the heat provided.
A benefit of tankless water heaters is efficiency. They only heat water when needed, so very little energy is wasted, lowering utility bills. Electric tankless water heaters are typically more efficient than gas ones; the challenge is finding accurate ratings.
Electric tankless water heaters are considerably easier to install than gas models because no venting is required. The devices are more compact and can be positioned just about anywhere that electricity and water can be provided.
Physical size is seldom a challenge with electric tankless water heaters. Water pipes and electrical conduits are small in diameter, so units are generally very compact and surprisingly slender. That said, dimensions might be important when installing point-of-use models. 041b061a72
