Tankless Water Heaters - What is a tankless water heater? Without a tank, how do they work? Traditionally, people have had hot water tanks in their homes. These are simply storage tanks for water, which keep it hot all the time. While you're sleeping, while you're out, that hot water tank is working. The benefit is that you get hot water when you turn on your tap, but as a lot of us know, that also means you can run out of hot water mid-shower. The electric meter, too, is always working. A tankless water heater, on the other hand, doesn't store the water. It heats it on-demand as you use it. The benefit here is that you are not wasting energy heating water you are not currently using, and since it heats when you need it, you won't run out of hot water with shampoo still in your hair (but again, those army showers are still good for conservation). Other benefits of a tankless water heater include:

*Compact design. They can be mounted onto a wall.
*They are built with replaceable parts so you will have yours forever.
*Tankless water heaters have a lower impact on the environment with almost entirely recyclable parts.
*They remain efficient during their lives. Traditional water heaters build up minerals from the water over time, decreasing their efficiency as they age.
*You won't come home to a soggy mess due to a tank leak.
*You can take a shower before work, then your partner can hop in, then your kids with no recovery time needed. Everyone gets the hot water they need.
*It bears repeating that tankless water heaters save you money. You can save from 11 to 69 percent off your hot water bill. With a traditional water tank, you are keeping 40 or 50 gallons of water hot all day and night. With a tankless water heater, you are using it only when you need to. The average consumer uses about an hour of hot water a day - and that's how much water is heated for you. .

How does a tankless heater work? - If you have ever run out of hot water in the middle of a shower, in the middle of winter, you will appreciate the on-demand supply offered by a tankless water heater. How does this miracle of hot water work? When you turn on your water tap, cold water goes through the unit and triggers the heating elements. As you increase or decrease the pressure, a valve adjusts the temperature accordingly so you have a consistent water temperature. You can adjust the heat settings from 100 to 140 degrees F. But how long does it take the water to heat? Are you negating your energy savings by running cold water needlessly while you wait for the hot? The heat time is very rapid and is powered by powerful gas or electric burners. You get hot water in the time it takes it to travel from the water heater to your faucet. That's it. No wasting cold water. Then when you're done with the water, the tankless water heater is done heating it. You can view the most popular Bosch models here.

Best Bosch Tankless Gas Water Heater:

Bosch Water Heaters - Bosch is an undisputed leader in this field: as mentioned, they are reported to be the only tankless water heaters available in the United States that were designed exclusively for the U.S. market. Such a simple thing, but it matters when it comes to paying your electric bill. They also sell more tankless water heaters than any other company in the field. Bosch tankless water heaters last for at least 20 years and can help you reduce energy bills by 50 percent, and possibly more if you cut back on your hot water usage a bit. Bosch makes both gas and electric tankless water heaters. A Bosch electric tankless water heater is best suited for homes that will use one hot water source at a time, such as the shower. This doesn't mean someone in the house can't wash their hands while someone else is doing a load of laundry, but it does mean you won't be able to do the laundry, take a nice hot bath, and run the dishwasher at the same time. If you want to do this, you'll need a Bosch tankless gas water heater. Let's take a look at their most popular models.

The Best Bosch Tankless Gas Water Heater - The right Bosch tankless water heater for you will depend on several factors, most importantly how much you want to spend and how many applications you want to be able to use at once. For instance, if you want to use your washer, dishwasher, and shower at the same time (really??), you can with the Bosch Aquastar 2700ES. This model is positively reviewed by Buzzillion and Amazon consumers, and the installation of one qualifies you for an energy credit for your taxes. The 2700ES can supply hot water for two to three showers at the same time. It is powered by natural gas and ignited by electricity and delivers 7.2 gallons of hot water per minute. Reviewers generally cite the compact design and endless hot water as its biggest strengths. Though one issue that many have had with Bosch, they say, is poor customer service. This may very well be because they have installed the Aquastar 2700ES or other model by themselves, voiding the warranty. You will want a qualified installer to do it for you to avoid this, and also to make sure that everything is in place. DIY is great, but not when you're going to cheat yourself out of warranty protection. This Bosch tankless gas water heater sells for about $1150 online at Amazon. You can get less expensive models that are intended for one point of use. The 125 series is a good choice, and their models are typically well received by reviewers. They are Bosch's most popular models and are designed for one major hot water outlet at a time, such as your shower. This is perfectly fine for most homes, and if you have a professional installer put it in for you, it has a 12-year warranty. Here is a look at the Aquastar 125:

*All of its water parts are made from solid copper or solid plastic, and all are replaceable and recyclable.
*The unit has stainless steel and aluminum construction.
*Solid copper heat exchanger.
*Safety thermostat and overheat shutoff protection.
*CSA design certified and compliant with ASHARE 90.1.

Popular Mechanics said of the 125, "The appliance blends time-tested technology...with high-tech features." This model costs under $1000. RECOMMENDED We suggest you browse the best selling Bosch tankless gas water heaters here.

The Best Bosch Electric Tankless Water Heater:

Bosch makes two electric tankless water heaters: the PowerStar AE125 and the PowerStar AE115. The AE125 offers 2.7 gallons per minute (gpm) at a temperature of 105 degrees F and can supply 2 sinks at the same time or 1 shower. At 115 degrees, it can provide 3 gallons per minute and supply 2 sinks or 1 dishwasher. It is 94 percent efficient. The AE115 offers 2.3 gpm at 105 degrees for a shower, bath, or laundry. At 115, it offers 2 gpm for 1 sink or dishwasher at a time. This model is 90 percent efficient. Both are smaller capacity than the gas tankless water heaters, but perfectly suitable for many households. If you live in the northern half of the U.S., it is best to get the AE125. HomeEcoFriendly says the PowerStar series can be a "perfect solution" for saving energy and avoiding cold showers. These units tend to score lower with consumers. One of the big issues with the AE125 is that it uses 120 amps of power, a rate that many homes cannot support. This seems to be the most common problem, and is certainly something you should be aware of before you purchase. It may be a better route to get a less expensive, one point Bosch gas tankless water heater if you are worried about power consumption. If you want to save money and increase your home's efficiency, look into Bosch tankless water heaters. Remember to size your unit properly for your home and needs, and enjoy that nice, hot shower.
