Q: We run out of hot water many mornings. I know a tankless water heater costs more to install than a standard one, but will a small tankless model really provide enough hot water for endless showers? - Lynn E.
A: A gas or electric tankless water heater can not only provide enough hot water for 20 consecutive showers in the morning, but it does this more efficiently than a standard tank-type water heater. An average-size family should notice $50 to $100 annual savings on its utility bills.
Some tankless water heaters can cost twice as much as a standard water heater, but the savings will pay back the higher cost. Since there is no tank to rust out, tankless water heaters have a very long life. They can also be repaired when a part wears out as opposed to a standard one which must be replaced every 10 or 15 years when the tank rusts out and leaks.
A lower-cost option is to install just a tiny point-of-use tankless water heater in the water pipe at the main shower or bathroom faucet. The electric ones are easiest to install in a bathroom. Some models operate on standard 110 volts, but the more powerful models use 220 volts. Some have digital controls that monitor the temperature up to 120 times per second.
Unlike older tankless water heaters, new ones with solid-state controls maintain a steady hot water temperature. This is accomplished by using variable gas burners or multiple-step electric heating elements which vary the heat output depending on how much hot water is being used at the time.
It is important to understand how a tankless water heater works to determine if one is your best choice. When someone opens a hot water faucet, the tankless water heater senses this and starts the gas burner or the electric heating elements. This heats the water as it flows through.
Gas models provide the greatest amount of hot water, up to six gallons per minute (gpm). If you try to simultaneously take three showers, run the clothes washer and dishwasher, you may exceed the instantaneous hot water output of the tankless water heater so the water temperature may drop.
The majority of the utility bills savings with a tankless model results from the elimination of the big tank of hot water and its losses. During summer, the heat loss through a standard water heater tank wall is a double cost because it makes your air conditioner run harder to cool your house.
Tankless water heaters (even powerful whole-house models) take up little space (about two cubic feet) and are often mounted on a wall or in a closet. Many of the gas models are direct-vent designs which do not require a chimney. They are ideal for switching from electric to gas (propane) heat.

Safe Spring Cleaning for Your Home and Family
Many parts of the country are already warming up to spring...and that means spring cleaning. But have you ever considered what you're using to clean your home...and if it's really safe for your family? The problem with cleaning products is that there is very little regulation and virtually no labeling requirements.
"A lot of cleaning products contain toxic ingredients that aren't properly regulated, disclosed, or in some cases even tested," said Sara Mohs, co-founder of simplyneutral™, a company that promotes sustainable living through non-toxic cleaners.
In fact, most household cleaners are produced using a petroleum-based formula. That's right, petroleum! In addition, they typically include chemicals, fragrances, and dyes that can be irritating to your eyes, skin, and respiratory tract.
In light of last week's Poison Prevention Week, here's a list of natural alternatives that work great and are probably already in your pantry:
Baking soda - We all know that baking soda absorbs odors, especially in refrigerators, but did you know it's also a simple and effective cleaner? Just mix baking soda with warm water for an inexpensive cleaner comparable to commercial "abrasive" cleaners.
Vinegar - White vinegar is actually a deodorizer and a disinfectant...making it a great all-purpose cleaner. Avoid using vinegar solutions on marble or grout, but it's perfect for all of the other surfaces in the kitchen and bathroom.
Lemon juice - Use lemon juice on hard-water stains, soap scum, even rust stains in the shower, tub, and toilet. Mix lemon juice with salt to remove stubborn stains from coffee pots. Or you can mix lemon juice with baking soda for a softer, paste-like cleaning solution. Add a little to olive oil for an effective wood polish. Blend it with water to make a potent air freshener.
Cornstarch - Cornstarch makes an effective glass and surface cleaner. Plus, you can combine 2 tbsp of cornstarch with 3/4 cup of baking soda for an inexpensive carpet freshener.
Borax - Also known as sodium borate, borax is best known as a hard-water laundry soap, but it also cleans wallpaper, painted walls, and other painted surfaces.
In addition to these natural ingredients, there are also a number of non-toxic cleaners that can be bought in stores. But make sure you consider a couple of points before making your purchase.
First, read the label carefully. "Although a cleaner may contain natural ingredients, it may also include dyes, fragrances, or synthetic preservatives," Mohs said. "For example, if the label says fragrances are added, it may contain up to 150 synthetic chemicals."
Second, you may want to take a quick look at the company itself to see if it is serious about producing natural cleaners that are safe for your family, your home, and the environment.
