You’ve probably heard of tankless water heaters, which heat up water a little differently than traditional storage tanks. While tank water heaters must keep hot water around at all times, tankless water heaters only heat up the water when you need it. This is beneficial for your wallet and for the system itself, but is a tankless system right for you? Let’s take a look at both storage tank water heaters and tankless water heaters to find out.

Is a Tankless Water Heater Right for You?
Monday, May 11th, 2015Tankless Water Heater Tip: How to Get the Right Size
Monday, January 9th, 2012Tankless water heaters are gaining popularity among Cheney homeowners because of their on demand hot water supply and space-saving design. Although they are more expensive than traditional tank water heaters, on demand water heaters are more efficient, reliable, and easier to install and maintain. Before choosing to install a tankless water heater, however, you will have to decide which size will meet your hot water needs.
Rather than storing hot water in a tank, the tankless models heat the water with individual units located near the application where hot water is needed, such as a shower or washing machine. For larger homes, some of these smaller units cannot heat enough water for several applications running at the same time. You can also install a single tankless water heater for the entire house, or separate ones for appliances that use more hot water.
Finding the proper size and type will depend on the flow rate—measured by a GPM (gallons per minute) number—that each fixture needs. Every application has a standard flow rate that must be added up in order to calculate the hot water demands for your entire home. For instance, if someone is using a sink with a 1.5 GPM at the same time another person is running a shower with a 2.0 GPM, the flow rate for the tankless unit would need to be at least 3.5 gallons per minute. You will have to add up the flow rate for all the applications in the house to get the minimum GPM figure for your tankless water heater.
In addition to flow rates, tankless hot water heaters are also measured by how much the water temperature needs to rise as it moves through the heating unit. You can determine the temperature rise for each application by subtracting the temperature of water coming in from the desired temperature going out. Once you add those together with the overall flow rates, you will know which tankless water heater can handle your overall hot water needs.
Before you buy an on demand hot water heater, it is best to talk to a professional installer. While the flow rates and temperature rise for most household appliances are fairly standard, these numbers can vary because of several factors that professionals are trained to calculate. Size is not the only factor to consider when shopping for a tankless water heater. Fuel type and efficiency should also be factored in to your purchase.

How to Lower Energy Costs for Your Athol Home: Water Heater Tips
Wednesday, December 28th, 2011If you want to lower the energy costs for your Athol home, the water heater might not be the first place you’d think to save energy. However, when you add up the savings from a few easy steps that can improve your water heater’s efficiency, it can make a significant difference in your utility bills.
Here are some of the ways you can reduce the use of hot water in the home and increase your energy savings.
Saving Energy by Using Less Hot Water
Even if you own an energy-efficient, tankless water heater, and you try to conserve water as much as possible, hot water usage can always be reduced in other areas. Installing low flow faucets and fixtures can provide up to 60% in water savings because they reduce the flow rate (gallons per minute) for each fixture. Tankless water heaters are also more efficient when they are used with any application with a lower flow rate.
Replacing older appliances that require a lot of hot water with more energy-efficient models is worth the money and effort because of the energy savings you will get in the end. Make sure you fix any leaks on older hot water faucet or fixtures. A leak that costs a dollar or two extra per month doesn’t seem like much, but it will add up over time.
Lower the Temperature on Your Hot Water Heater
For every 10°F that you lower the water temperature on your hot water heater, you save between 3% to 5% in energy costs. The manufactured setting for most water heaters is 140°F, but most homes only require a maximum temperature of 120°F. Check your owner’s manual before you lower the temperature on your water heater to find out what the recommended settings are and how to change them.
Insulate Your Water Heater Tank and Water Pipes
Whether you have a gas or electric hot water heater, you can find fairly inexpensive and easy-to-install insulators or “jackets” for your water heater tank. Every tank has an R-value that determines how much heat it loses, so unless it is a high value, your water heater tank needs insulation. Call a professional or check your owner’s manual for the R-value of your hot water heater, but the general rule is that if the tank is warm when you touch it, you need more insulation.
You can reduce emissions and your energy costs simply by paying more attention to how much hot water you are using in your Athol home. For more tips and expert advice, call ACI Northwest to speak with one of our technicians.
