Instantaneous water heaters provide hot water instantaneously and only as it is needed. When you turn on a hot water tap in your home, cold water travels through a pipe into a heat exchanger in the unit.
The cold water is heated in the heat exchanger via district heating water or another waterborne heat source. As a result, the water heaters deliver a constant supply of instant hot water.
The biggest advantage of a water heater with heat exchanger is: It never goes empty! Danfoss instantaneous water heaters can supply from one up to four households with domestic hot water and are very suitable for one-family houses.
Installation and maintenance
Proper installation and maintenance of your water heater can optimize its energy efficiency. Proper installation depends on many factors. Therefore, it is best to have a qualified plumbing and heating contractor install your water heater for you.
It is necessary to check and maintain the water heater on a regular basis in order to keep it in good operating condition. The frequency of the maintenance and service inspections should be according to system manufacturer specifications and local legislation. Most instantaneous and tankless hot water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that extend their life by many more years.
Periodic water heater maintenance can significantly extend your water heater's life and minimize loss of efficiency. Read the instructions that come with the water heater for our specific maintenance recommendations.
Features and benefits
