Selecting a New Water Heater

Whether you’re replacing a worn-out existing water heater or looking for the best model for a new house you’re building, it pays to choose carefully. Look for a water heater that satisfies your hot water needs and uses as little energy as possible. Often you can substantially reduce your hot water needs through water conservation efforts.

• Think About a Replacement Now: If you're like most people, you’re unlikely to go out looking for a water heater until your existing one fails, leaving little time to look for a water heater that most appropriately fits your needs and offers the highest level of energy efficiency. A much better approach is to do some research now. Figure out what type of water heater you want—gas or electric, storage or demand, stand-alone or integrated with your heating system, etc. Then, figure out the proper size for your household.
• Sizing a Water Heater: The capacity of a water heater is an important consideration. The water heater should provide enough hot water at the busiest time of the day. The ability of a storage water heater to meet peak demands for hot water is indicated by its "first hour rating." This rating accounts for the effects of tank size and the speed by which cold water is heated. Demand water heaters should be sized according to the required gallons per minute (gpm) flow rate and temperature rise required for your largest expected hot water fixture (usually a shower).With solar water heaters, you should discuss your requirements carefully with the solar water heating salesperson. You will need to size both the solar hot water system itself and the back-up electric or gas water heater. It generally makes the most sense to size a solar water heater to provide two-thirds to three-fourths of your total demand, and provide the rest with a back-up system.
• Fuel Options: What type of fuel makes the most sense for your water heater? If you currently have an electric water heater and natural gas is available in your area, a switch might save you a lot of money. Oil- and propane-fired water heaters are also usually less expensive to operate than electric models. Before you rule out electricity, though, check with your utility company. It may offer special off-peak rates that make electricity a more attractive option.
• Look for Sealed Combustion or Power-Vented Systems: For safety as well as energy efficiency, look for gas- or oil-fired water heaters with sealed combustion or power venting. Sealed combustion means that outside air is brought in directly to the water heater and exhaust gases are vented directly outside. The combustion is totally separated from the house air. Power-vented equipment can use house air for combustion, but flue gases are vented to the outside with the aid of a fan. In very tight houses, drawing combustion air from the house and passively venting flue gases up the chimney can sometimes result in back-drafting of dangerous combustion gases into the house.

COMPARING THE TRUE COSTS OF WATER HEATERS

When comparing the cost of various water heating options, keep in mind that there are two types of cost you need to look at: purchase cost and operating cost. Life-cycle costs, which take into account both the initial costs and operating costs of different water heaters, provide a much more accurate representation of the true costs of the water heater than the purchase price alone. Life-cycle costs for the most common types of water heaters under typical operating conditions are shown in the table here. When both purchase and operating costs are taken into account, one of the least expensive systems to buy (conventional electric storage) is one of the most costly to operate over a 13-year period. An electric heat pump water heater, though expensive to purchase, has a much lower cost over the long term. A solar water heating system, which costs the most to buy, has the lowest yearly operating cost among electric systems.

Upgrading Your Existing Water Heater

Even if you aren’t going to buy a new water heater, you can save a lot of energy and money with your existing system by following a few simple suggestions.

• Conserve Water: Your biggest opportunity for savings is to use less hot water. In addition to saving energy (and money), cutting down on hot water use helps conserve dwindling water supplies, which in some parts of the country is a critical problem. A family of four each showering five minutes a day can use about 700 gallons per week—a three-year drinking water supply for one person! Water-conserving showerheads and faucet aerators can cut hot water use in half. That family of four can save 14,000 gallons of water a year and the energy required to heat it.

• Insulate Your Existing Water Heater: Installing an insulating jacket on your existing water heater is one of the most effective do-it-yourself energy-saving projects, especially if your water heater is in an unheated basement or space. The insulating jacket will reduce standby heat loss—heat lost through the walls of the tank—by 25–40%, saving 4–9% on your water heating bills. Water heater insulation jackets are widely available for around $10. Some newer water heaters come with fairly high insulation levels, reducing (though not eliminating) the economic advantages of adding additional insulation. In fact, some manufacturers recommend against installing insulating jackets on their energy-efficient models. Always follow directions carefully when installing an insulation jacket. Leave the thermostat(s) accessible. With conventional gas- and oil-fired water heaters, you need to be careful not to restrict the air inlet(s) at the bottom or the draft hood at the top.

• Insulate Hot Water Pipes: Insulating your hot water pipes will reduce losses as the hot water is flowing to your faucet and, more importantly, it will reduce standby losses when the tap is turned off and then back on within an hour or so. A great deal of energy and water is wasted waiting for the hot water to reach the tap. Even when pipes are insulated, the water in the pipes will eventually cool, but it stays warmer much longer than it would if the pipes weren’t insulated.

• Lower the Water Heater Temperature: Keep your water heater thermostat set at the lowest temperature that provides you with sufficient hot water. For most households, 120°F water is fine (about midway between the “low” and “medium” setting). Each 10°F reduction in water temperature will generally save 3–5% on your water heating costs. When you are going away on vacation, you can turn the thermostat down to the lowest possible setting, or turn the water heater off altogether for additional savings. With a gas water heater, make sure you know how to relight the pilot if you’re going to turn it off while away.

How To Heat and Cool Your Home Efficiently

How to Heat & Cool Your Home Efficiently

As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills — and your comfort. Take these steps to increase the efficiency of your heating and cooling system.

Change your air filter regularly

Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

Tune up your HVAC equipment yearly

Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort.

Install a programmable thermostat

A programmable thermostat is ideal for people who are away from home during set periods of time throughout the week. Through proper use of pre-programmed settings, a programmable thermostat can save you about $180 every year in energy costs.

Seal your heating and cooling ducts

Ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent — and sometimes much more.

Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house.

What is a HVAC Spring Tune Up

What is a HVAC Spring Tune Up

With spring just around the corner, now is the time to schedule a tune up for your air conditioning system. Don’t wait until it gets hot to find out that your air conditioning system is not working up to capacity or not working at all. By then, every air conditioning technician in the area will be working overtime and you might end up waiting days before they can make it out to your home. Schedule your HVAC service now and your system will be ready to go when summer temperatures hit.

Regular residential HVAC maintenance is important to keep your air conditioning system in peak operating condition. Like any mechanical system, wear and tear takes a toll on your air conditioning system. Your system worked hard all last summer keeping your home and family comfortable and a spring tune up will help keep it great shape again this summer.

Your HVAC technician will do a thorough scheduled maintenance service including inspecting your entire system, lubricating bearings, cleaning the coil and condenser, replace the air filter, check and adjust refrigerant levels as needed, and measure the supply and return temperature differential.

A good air conditioning technician will also be able to identify any issues or problems that your system may have and correct them before the system fails completely and leaves you sweltering in the summer heat.

Spring is also an ideal time for a full system efficiency analysis to get the most out of your air conditioning system. Your technician can recommend a package of improvements designed to increase your air conditioning system’s efficiency. The result will be increased indoor comfort and lower electric bills.
