American Heat Tankless Electric Water Heater (ADK-18)

PRLog (Press Release) – Mar 26, 2009

While we are in this economic depression the idea of cutting down on our utility bills is quite appealing. Your utility bills can be cut at least by 20% just by installing an tankless water heater. These savings could also add up for all of the United States.

We could easily save in one year:

290 Million gallons of Fuel Oil
6 Billion hours of Kilowatt electricity
164 Million gallons of Propane

If every American were to switch their traditions water heater to tankless systems the costs would add up quickly but the savings and payback would only take as little as three years.

What are the annual savings?

The savings will vary from one tankless water heater brand to the next, but here are a few of the basic overall estimated saving on your utility bills by switching.
15%-25% savings with an electric tankless water heater
25%-35% savings with a gas tankless water heater
65%-70% savings more with a gas tankless water heater compared to an electric unit

These percentages change according to fuel charges and the rising cost for electricity and can very year to year.

Using a typical utility bill of about $200 per month you can add up the estimated savings of  up to $50 a month with an electric or $70 with a gas unit. That in turn adds up to a $600 or $840 savings for the whole year.

The fact is that tankless water heater units are designed to outlast many years of use. Because they work only “on demand” thus reducing your energy cost and well as wear and tear on the unit itself. With a regular tankless water heater it is constantly using electricity even while you are sleeping. With a regular tank water heater they will need replacing on average every 3-8 years.

A regular tank water heater stores water in the tank constantly whether you are using it or not. When water sits in the tank it will deposit minerals at the bottom. Over time the mineral will build up and create a blanket on the bottom, thus reducing the amount of water the tank will hold and makes the water heat less efficiently. This means that your electric usage will go up because of the tank is working harder at keeping the water hot. Each year you will pay more to keep tank water heater running.

How much does a tankless system cost compared to the regular tank heater?
The installation of a tankless system will cost you considerable amount more than installing a regular tank type water heater but if you purchase the electric tankless unit most regular hand men have no problem with the installation.

A small point of use tankless unit on average can cost around $150-$200.

An Electric whole house unit can be found for as little as $500 to about $1000 for a larger (3+ bathroom) home.

An Gas whole house unit can be found starting at about $800 up to $2000 for a larger (3+ bath) home.

But considering the efficiency of these units, the initial investment will not seem that expensive. Overall the investment in a tankless water heater is well worth it in the long run and will save you money in no time at all.

 
 

takagi tankless water heaterA payback analysis for a tankless water heater is something that every energy conscious consumer should consider…

There are a lot of tankless water heater manufactures claiming a wide range of savings on your next water heating bill. A quick search on the web will show you a percent reduction of up 80%.   However the question still exists: how much would you really save on your water heating bill using a tankless water heater?

Most importantly what is the payback or ROI of the average tankless water heater and how does it compare to a traditional tank hot water system? Let us try to answer these questions:

Annual costs associated with water heaters of any type are divided into (3) categories:

  1. Energy costs to heat the water from its incoming temperature to the desired temperature.
  2. Standby energy costs: in the case of traditional tank heaters, standby cost is the cost of the energy to keep the water hot in the tank all day. For a tankless water heater standby cost is the cost of energy when the tankless water heater is running idle (minimal).
  3. Installation costs: This is the cost to install the heater and all its piping system.

So let us examine these costs for both traditional tank heaters and tankless water heaters in detail.

Average Annual Traditional Tank Heater Costs

- Annual hot water demand: 87 gallons / day

- 335 days / year = 29,145 gallons/ year

Power to heat up 1 gallon of water from 57 to 110F according to the multi-housing laundry association is 0.2 kWh. The annual power requirement of heating the water from 57 to 110F for an American household is: 29,145 gallons/ year x 0.2 kWh/ gallon = 5,900 kWh/ year

The cost of 5,900 kWh: 5,900 kWh/ year x $0.11/ kWh = $649/ year

The cost to keep one gallon of water hot is $0.003. So, the cost to keep 21,145 gallons of water hot (standby): 21,945 gallons/ year x $0.003/ gallon = $87

So the total annual cost of heating water using a traditional tank system is $649 + $85 or $736

Average annual Tankless Water Heater Costs

Average energy to heat water to 110F is 6.2 kW

Average daily usage is 1.5 hours

Daily power needed to heat the water to 110F is: 1.5 hours x 6.2 kW = 9.3 kWh

Annual costs to heat water using a tankless water heater is: 9.5 kWh/ day x 335 days/ year x $0.11/kWh = $343

The total cost of heating water using a tankless water heater is $343 + $17 or $360.

What do these numbers mean?

The percent annual savings using a tankless water heater over a traditional tank system is 50% or $375.

This amount ($375) is equal to the cost of an average mid-size tankless water heater. Please note: Installation costs were found to be comparable for both tank and tankless systems, ~$150.

In addition there is the potential for tax credits for any tankless water heater. Please visit http://www.energy.gov/taxbreaks.htm for more information.

Given the longer life of a tankless water heater at 22 years versus a tank system 10 years there is the potential of saving over $4,000 over the long term.

The incoming water temperature from which the Department of Energy (DOE) calculations are made, has been established at 57F. In many parts of the world one does not normally experience inlet temperatures this cost year round however, we used 57F as our inlet temperature. 110F is the average household hot water operating temperature. This translates to 53 degrees of temperature rise for both tank and tankless water heating systems. According to the U.S. Department of Energy (July 2006) the average American household consumes 87 gallons of hot water per day. Average cost of electricity for the at the time of writing, is $0.11 kWh, as per the Department of Energy (DOE). Based on a DOE report July 2006.
