Hot water can be a luxury for most people, especially in winter. Nothing can make you feel more relaxed than a nice, hot shower or bath. But for all this, you need to have hot water in the first place, which is not possible without a water heater.
In this article, we will be discussing details about the different types of water heaters manufactured by Bosch, and which one is best for you and meets your requirements.
How Does Bosch Compare to the Competition?
Bosch is a company renowned all over the world for their technology and services, which started out all the way back in 1886 and is still not just going strong, but is actually even better than ever. It is able to hold a strong list of clientele, some would say, unlike its competitors. Some things that make Bosch a better company than its competitors are:
Old and Experienced
Bosch was born back in 1886, and that makes it over a century-old company. It has been providing people with what they want and need for a long time now. Its old age makes it a sort of pioneer, a beacon for the other companies, and new younger competitors.
In addition to that, it has remained solid and standing for so long, with the wishes of the customers always being met and the people always being satisfied with their service. It is a conglomerate, which has been here for a long time and will probably be here in the many years to come as well.
On Top of the Game
Bosch being an older, more experienced company, knows the ins and outs of the business. As part of a business in which you can be a king one moment and an outcast the other, they have set an example and stood tall through all kinds of good and bad times. The result of their steadfastness and the steady climb is that now they are fully aware of how to tackle even the most difficult of circumstances, which cannot be said for most of their competition. They have experience behind them and, as such, are on top of their game.
Know What People Want
Being an experienced company has its perks, what with knowing the ins and outs of the business, with which friends are actual friends and which are hidden enemies who want to steal your ideas. You get to know and understand all of this. And not just get to know the friendly faces, but to know your own customers and what they want too. If you want a list of prominent clientele and satisfied clients, you need to know your people and what they want from you. And Bosch so far has nailed this.

What Kind of Warranty Does Bosch Offer?
The warranty that Bosch offers can be divided into two:
Manufacturers and Extended Warranty
Bosch offers manufacturer’s as well as extended warranty after the payment of an additional fee. It is very helpful in long term cases because you never know what may happen down the road. Its customer service is also very accommodating and will change your damaged product or device, within the limits of the warranty, for a new one. Generally, a manufacturer’s warranty lasts only 2 to 3 years, so it is good to get an extended warranty so that the company may be able to recompense you for damages that may come under the warranty limits.
Warranty for BOSCH Tankless Water Heaters
Now, generally, tankless water heaters have a lifetime of 20+ years. This is because unlike normal water heaters with storage tanks, they do not corrode or rust because of water damage over the years. It makes them last for up to or more than 20 years, whereas normal water heaters only last for 6 to 12 years.
Bosch gives warranties based on different aspects and is divided into a heat exchanger, all other parts, and labor. Usually, the heat exchanger warranty is from 5 to 15 years based on the model. The warranty for all other parts is from 2 to 5 years, but the model and the labor warranty is for one year.

Now, some people may still not understand a few things and may become confused. For such people, we have compiled a list of commonly asked questions, which we hope will be helpful for them in finding out their required answers.
How Do You Flush a Bosch Tankless Water Heater?
The steps to flush a Bosch tankless water heater are as follows:
- Shut the unit and the water supply OFF.
- Release the water pressure by opening hot water taps.
- Disconnect the water inlet and outlet and drain the water.
- Take one of the three hoses, connecting it with the inlet of the water heater and outlet of the pump.
- Take the second hose, connecting one end to the water heater outlet and submersing the other end in the bucket with the descaling solution.
- Take the third hose, connecting one end to the inlet of the pump, and putting the other in the bucket. This will act as a filter to keep the larger particles from entering the system again.
- Check to make sure all the connections are tight and that there is no leakage.
- Run the pump through the tankless unit and its heat exchanger. Depending on the lime build-up, the returning solution might be quite dirty. It will take a while for it to come out fully clear.
- After you are done with flushing out the heat exchanger, it is time to connect with the cold water line and flush the unit with clean water.
- Connect the hot water line and open all the valves. Turn the power back on and run the unit like normal.
How Do I Choose the Right Size of a Tankless Water Heater?
The following steps will be helpful in choosing the right size of a tankless water heater:
- Calculate the maximum number of taps you want to run and their total flow rate. Then, add them up (gallons per minute). This is the flow rate you will want for the water heater.
- Calculate your required temperature rise. To do this, subtract the incoming water temperature from the desired output temperature. You will get your temperature rise value.
- How much hot water is needed at a time? Do you need to run 2 showers at the same time? Or a shower and a sink? Flow rates will determine this point.
- Remember, gas tankless water heaters are able to have a larger temperature rise than electric ones, according to the flow rate.
These are just a few pointers to make sure you buy the perfect product for you and your family.
How Long Do Tankless Water Heaters Last?
Unlike other water heaters that store water in a tank and corrode and rust over time, tankless water heaters are able to last nearly 20 or more years, depending on the make of the product.
Do Tankless Water Heaters Run Out of Hot Water?
In a tankless water heater, the water is heated up as it is used. There is no place to store the water, like a storage tank in some water heaters. For example, if you turn on the shower for hot water, the heater system will detect the movement of water in the pipelines and begin heating it through a heat exchanger. It will keep doing this for as long as the water is needed, so in this sense, no, tankless water heaters do not run out of hot water.
