If you are planning to purchase a tankless water heater from them, then there are plenty of Bosch tankless water heater reviews online that can help guide your decision.


Pros and Cons of Bosch Water Heaters

There are many reasons why you should opt for a Bosch tankless heater over conventional tanks. For starters, the heater’s on-demand technology allows you to save energy since the unit only turns on the moment you need hot water. Traditional tank models operate 24 hours a day in a continuous cycle of heating and re-heating water (which also decreases the water’s freshness). Over time, the heater becomes less and less efficient since sediments tend to build up at the bottom of the tank. As a result, the heat does not effectively reach the water through the buildup, leading to higher utility bills.

With a Bosch tankless model, your utility bills are drastically reduced by half. Many of the brand’s tankless models also qualify for a federal tax credit of up to 30%. Bosch also eliminates the “cold water sandwich” problem by supplying an unlimited supply of hot water, thanks to its modulating burner technology. This technology also allows you to precisely control the heater’s temperature.

A Bosch tankless heater does not only save you money in day-to-day operation, but it is also a worthwhile long-term investment. Unlike a traditional tank heater that has a maximum life span of 12 years, a Bosch tankless unit is designed to last for more than 20 years.

Bosch has a line of tankless heaters for both residential and commercial consumers. Bosch understands that homeowners are looking for a convenient and reliable source of hot water, paired with a good warranty and utility cost savings. On the other hand, Bosch provides commercial establishment’s higher demands, with some units designed to provide over 12 gallons per minute.

The reviews Bosch tankless water heaters received have been generally positive. Many buyers who were good at DIY jobs had no trouble installing the tankless unit themselves, which helped them save on installation costs. As expected, many consumers liked the fact that their heaters only consumed power when hot water was needed, instead of running round the clock. Many also commented on how quickly hot water was supplied to their faucets and shower heads, unlike with regular tank heaters where you had to wait a few minutes to get the temperature you desire.

Of course, Bosch tankless water heater reviews have not been all perfect. A couple of customers had some complaints about the Bosch tankless unit they purchased. A customer was annoyed by the fact that their new Bosch unit required a gas supply pipe with a larger diameter, hence requiring them to upgrade. One customer also complained about a leak that developed after a couple of years’ use.
