Instantaneous water heaters with heat exchanger
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.

Termix Novi
The Termix Novi is an instantaneous water heater featuring superb heat extraction and high performance. The Termix Novi is suitable for flats, single-family houses as well as for small apartment buildings. The water heater is available in two sizes, either for 1 apartment, or up to 4 apartments. The Termix Novi is applicable for decentralized heating systems – as well as for district heating networks with summer operation at low temperatures or with changes in differential pressure. The heat exchanger in Termix Novi cools the district heating water very efficiently, thereby creating a very good operation economy.
Termix One Solar
The Termix One Solar is an instantaneous water heater, featuring superb heat extraction and high performance. The Termix One Solar is applicable for heating systems with buffer accumulators, solar systems or for other heat sources, where a very low return temperature is preferred. The water heater is available in three sizes, either for 1 apartment, for 1-4 apartments or for 5 up to 10 apartments. The large heat exchanger cools out the water in the primary return line very efficiently, thereby creating a very good operation economy. A flow switch in cold water mains is controlling the primary heating pump. An optional circulation pump together with a thermostat can maintain the circulating temperature at a desired temperature.
Termix One-B
The Termix One is an instantaneous water heater featuring superb heat extraction and high performance. The Termix One is suitable for flats, single-family houses as well as for small apartment buildings with up to 4 apartments. The water heater is available in two sizes, either for 1 apartment or for 1-4 apartments. The Termix One is applicable for decentralized heating systems – as well as for district heating networks with summer operation at low temperatures or changes in differential pressure. The Termix One heat exchanger cools the district heating water very efficiently, thereby creating a very good operation economy.
ThermoDual®-FLS
Domestic hot water provision by instantaneous heater is an efficient and hygienic optimal solution. Hot water is not stored and will be produced only on request. Habitats for bacteria,such as legionella are virtually non-existent. If the conditions for connection of these systems are given (sufficiently high capacity on heating side to cover peak load) or buffer tanks is present, these systems can be used unrestricted.
