Instantaneous water heaters
Instantaneous water heaters provide hot water instantaneously and only as it is needed. Danfoss offers a comprehensive range of products with different control solutions based on principles of flow, thermostatic, flow and thermostatic or electronic controlling. 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.

How does instantaneous water heater work?
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 several households with domestic hot water and are very suitable for one-family houses, small block of flats and small commercial buildings.
- Easy to install, requires little space and is simple to operate.
- Low operational temperatures.
- Sufficient supply of DHW
- Operates independently of differential pressure and flow temperature
- Pipes and plate heat exchanger made of stainless steel
- Minimized risk of lime scale and bacteria formation.

EvoFlat 4.0W
Danfoss EvoFlat 4.0 station is particularly suitable for multi family buildings with central heat generation or district heating. The innovative unit sets new standard. It consists of functional blocks made of a specially reinforced PPS composite material. This makes the station extremely lightweight and limits internal heat emission. The smooth surface reduces the risks of scaling and clogging.
All components are assembled with newly designed click-fit connections. Compared to conventional substations with pipes and screw connections, this new connection technology does not require retightening during installation and commissioning.
Primary side (DH)
The flat station is equipped with two differential pressure controller and a central strainer. A summer bypass keeps the supply line warm during standstill. This ensures a fast response time for DHW during the summer. The bypass is thermostatically controlled.
Domestic hot water (DHW)
Four sizes of heat exchanger are available to cover all requirements from 37 kW up to 70 kW. The Evoflat 4.0 W is equipped with an intelligent controller that regulates the supply side flow based on the domestic hot water temperature and the volume of water drawn. The station features an integrated differential pressure controller on the supply side of the domestic hot water heating system. This eliminates the need for hydraulic balancing of the station. If necessary, the station can be expanded with a hot water circulation set.
