Water Heaters How A Water Heater Works: Most problems with water heaters are announced by noises or by water that's either too hot or not hot enough. Often you can call a professional at Sugar Bear Plumbing, Inc. to analyze the problem. Gas leaks call for immediate help, dial 911 or call PG&E and then dial Sugar Bear Plumbing, Inc., a Licensed & Bonded Professional Certified Gas Installer and Repairman. Whenever someone turns on a hot water faucet, heated water is drawn from the top of the tank and is replaced by cold water that is carried to the bottom through the dip tube. When the water temperature drops, a thermostat activates the water heat source; a Burner in a gas model or two heating elements in an electric model. A gas water heater has a flue running up the center and out the top, to vent deadly gasses. An electric water heater needs no venting. In both, an anti-corrosion anode attracts corrosion that would otherwise attack the tank's walls. How A Tankless Water Heater Works:  Tankless
water heaters are available in electric, natural
gas and propane fired models. The electric
tankless water heaters have advantages over tank
type electric models but very few provide enough
capacity to serve multiple fixtures with only
one unit and may require a larger electrical
service to operate them. This has kept most
builders from using them in new construction.
Although they do tend to work well in small
home, condo or apartment applications where gas
is not an option. We are going to talk about the
gas fired units.Tankless water heaters work on demand by using sensors and computer boards to monitor the flow of water and change the rate of firing to supply just the amount of hot water required for the current demand. (They are also called on demand heaters) This means that they burn less gas to supply hot water to something like a sink than they would if you are using multiple fixtures at the same time. This modulating firing rate also makes them very efficient to operate as you are only using the exact amount of fuel needed at that time. A term that should be avoided is "instantaneous". Tankless water heaters are not instantaneous. It does take them about 2 seconds to go from their at rest "off" mode to producing hot water at the set point temperature. This is not a big issue however. The problem is if a consumer thinks by hearing the term "instantaneous" that they will get water at every outlet in the house instantly if they get a tankless heater, they will be disappointed. Typically, tankless water heaters provide hot water at a rate of 2�5 gallons (7.6�15.2 liters) per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a demand water heater to its limit. To overcome this problem, you can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water. You can also install separate tankless water heaters for appliances�such as a clothes washer or dishwater�that use a lot of hot water in your home Changing the type of water heater will not improve the speed of the delivery of water unless the location of the heater is altered or if a recirculating system is installed. Because of their small size of course, many times when a tankless heater replaces a tank, it can be moved to a more central location or nearer to the fixtures it is to serve. This may cut down on the lag time considerably Tankless Water heaters save space in a home because they take up NO floor space. They also do not require protection from vehicles if installed in a garage and are so small they can be installed in a crawl space or attic as well. If you really need space, many can be installed outdoors giving you all of your interior space back. Energy Savings of tankless water heaters: For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%�34% more energy efficient than conventional storage tank water heaters. They can be 8%�14% more energy efficient for homes that use a lot of hot water�around 86 gallons per day. You can achieve even greater energy savings of 27%�50% if you install a demand water heater at each hot water outlet.
