Riscaldamento diretto e acqua calda sanitaria
Direct heating stations with instantaneous domestic hot water preparation are used in single-family houses, where pressure and temperature conditions allow direct connections, but the most common use is in the multi-family buildings with decentralized heating and DHW installations.

EvoFlat 4.0F
Danfoss EvoFlat 4.0 F station is particularly well suited for apartment buildings with central heat production or district heating supply. The innovative unit sets new standards. It consists of functional blocks made of a specially reinforced PPS composite material that limits internal heat emissions. The smooth surface of the composite section reduces the risk of deposits and clogging. All components are mounted with the newly developed Click-Fit connection, which does not require re-tightening compared to conventional stations with pipes and screw connections. The station is very light and easy to install and service thanks to good access to all components. It is delivered with an attractive black EPP cover that also ensures good thermal insulation.
Primary side (DH)
The station is equipped with two differential pressure regulators, one for DHW and one for heating, which eliminates the need for hydraulic balancing. A central strainer is installed to protect the station’s components. A thermostat-controlled summer bypass keeps the supply line warm outside the heating season or during standstill, ensuring a quick response time for domestic hot water. A fitting piece is installed that can be easily removed for installation of a heat meter, along with a sensor pocket for the heat meter’s temperature sensor. The heating supply flow pipe is additionally insulated so it does not affect the temperature of the cold water.
Heating (HE)
The station supplies radiator heating circuits with the flow temperature provided by the supply. The integrated differential pressure regulator creates optimal operating conditions. A zone valve is integrated in the return side. Time-dependent temperature control can be carried out using an optional actuator and room thermostat. Installation of a return temperature limiter is possible to ensure optimal cooling of the heat source.
Domestic hot water (DHW)
The station can be ordered with one of four sizes of heat exchangers, covering all domestic hot water needs from 37 kW up to 70 kW. The new Danfoss micro-plate heat exchangers are highly efficient and have a lower risk of blockage due to limescale formation. The station is equipped with an intelligent controller that regulates the primary-side supply based on the set domestic hot water temperature and the tapped water volume. A fitting piece is installed that can be removed for installation of a water meter. There is a return line for the cold domestic water so that the total water consumption runs through the same meter. If necessary, the station can be easily expanded with a domestic hot water circulation set. The station can, if required, be ordered with a water hammer arrestor installed on the hot water outlet.
EvoFlat FSS
Product
The EvoFlat FSS is a compact and user-friendly flat station designed for use in multi family buildings. It is particularly suitable for two-pipe systems in residential buildings supplied with heat from a central heat source, such as district heating, boilers, solar heating systems, heat pumps, and similar installations.
All pipes are made of stainless steel and connected using Danfoss Hair-pin technology. Compared to traditional stations with threaded connections, this innovative connection method requires no retightening during installation.
The rear panel consists of an EPP insulation plate, complemented by a heat-insulating front cover, ensuring minimal heat loss.
Primary side (DH)
The flat station is equipped with a differential pressure regulator, integrated into the main regulator type TPC M and a central strainer. A thermostatically controlled summer bypass maintains the heat supply at operating temperature, ensuring a rapid domestic hot water (DHW) response outside the heating season.
Heating (HE)
The flat station supplies the radiator circuit with the same temperature as the heat source. The differential pressure regulator ensures efficient heating operation. For time-dependent temperature control, the station can optionally be equipped with an actuator for the zone valve integrated into the regulator.
Domestic hot water (DHW)
Domestic hot water is heated via a heat exchanger using the flow-through principle. Three sizes of heat exchangers are available, covering capacities from 37 to 55 kW.
The domestic hot water temperature is regulated by the self-acting TPC-M regulator (with integrated differential pressure regulator), ensuring a constant DHW temperature even with fluctuating supply temperature, flow, and differential pressure.
If desired, the station can be supplied with built-in DHW circulation.
EvoFlat RENO 2.0
EvoFlat Reno 2.0 è una stazione di riscaldamento per appartamento per riscaldamento diretto e produzione continua di acqua calda sanitaria in impianti a 2 tubi, specificamente progettata per sostituire le caldaie a gas. Mentre gli attacchi esistenti per l'acqua calda e fredda, così come le linee di mandata e ritorno del circuito di riscaldamento secondario, possono essere riutilizzati senza modifiche sostanziali, si consiglia di far passare i collegamenti per la mandata e il ritorno del riscaldamento primario attraverso la canna fumaria. Le linee di alimentazione primaria sono collegate dall'alto di serie. Tutte le tubazioni sono realizzate in acciaio inossidabile e isolate termicamente. .
Lato primario (DH)
La stazione è alimentata con acqua di riscaldamento da una fonte di calore. La stazione appartamento è dotata di serie di un termostato per l'acqua calda, un regolatore di pressione differenziale, un filtro, un bypass estivo, un supporto per sensore M10 e un raccordo per l'installazione di un contatore di calore.
Riscaldamento (HE)
Il regolatore automatico di temperatura TPC-M con regolatore di pressione differenziale integrato garantisce condizioni operative ottimali per il riscaldamento e l'acqua calda sanitaria. Opzionalmente, è possibile utilizzare un attuatore e un termostato ambiente per controllare la temperatura ambiente. È necessario rispettare le leggi e le linee guida nazionali utilizzando un set di collegamento ad alta temperatura opzionale.
Acqua calda sanitaria (ACS)
L'acqua calda sanitaria viene riscaldata tramite uno scambiatore di calore basato sul principio di flusso. La temperatura dell'acqua calda sanitaria è regolata dal regolatore automatico TPC-M. Questo regolatore combinato garantisce la massima semplicità d'uso fungendo da valvola idraulica e termostatica combinata. La sezione a flusso controllato consente il flusso attraverso lo scambiatore di calore sui lati primario e secondario solo durante l'utilizzo dell'acqua calda. Il flusso viene bloccato immediatamente dopo il completamento del prelievo di acqua calda. Il regolatore TPC-M garantisce una temperatura costante dell'acqua calda sanitaria anche in caso di temperature di mandata e pressioni differenziali variabili. Dotato di bypass estivo di serie.
