Water leading stove

With a water-bearing stove from DROOFF you heat cheaply and fairly sustainably. You are almost independent of fossil fuels and protect the climate. Store the heat of your stove for several days and use the energy of your firewood in all rooms of your house. Feed both your heating and your domestic water with ecologically obtained heat.

The advantages of a water-bearing stove from DROOFF
at a glance:

• attractive heating cost savings of up to 50
• Heating and hot water independent of fossil fuels
• use of stored hot water in the entire house, even days after the last stove operation
• optimal support for your heat pump, when the expensive electric heater comes on in sub-zero temperatures

Approx. 2/3 of the heat is released to the water pocket. The remaining 1/3 is released into the room as pleasant radiant and convection heat. So you can enjoy the cosiness of the crackling fire even if your installation room is small or your building is well insulated. The energy dissipated to the buffer storage tank prevents your installation room from overheating.

The heated water reaches the buffer storage tank via a control and pump system. This serves as an intermediate station for the stored heat, which can then be used as heating and service water throughout the house over several days. The heat transport takes place in a closed circuit.Aboiler safety group andathermal discharge safety device ensure that the safety of the system is always guaranteed, even in the event of incorrect operation or power failure.

And this is how it works!

In heating-up mode - the "small circuit"
In order to avoid condensation and gloss soot on the heat exchanger surfaces, rapid heating-up and water temperatures of more than 55 °C are necessary. Therefore, the combustion chamber is first brought to operating temperature before the heating circuit pump is switched on. When the water temperature exceeds 58 °C, a certain part of the flow is added to the return flow via a bypass (return flow temperature increase) "in the small circuit".

During operation - the "large circuit"
The temperature difference controller (TDR) controls the volume flow to the buffer tank during operation. It ensures a consistently high temperature level and efficient buffer loading. As the temperature of the buffer tank increases, the proportion of the admixed flow decreases until the entire volume flow circulates in the large circuit. Depending on the water temperatures between the water-bearing stove and the buffer storage tank, the water is only fed into the buffer when there is a sufficiently high temperature difference.

The thermal discharge safety device
The thermal discharge safety device is an emergency cooling system for your water-bearing stove. Should your water-bearing DROOFF stove ever get too hot (e.g. because the pump is not running due to a power failure), the Thermal Overflow Protection ensures that the stove is cooled down with cold tap water. All water-bearing DROOFF stoves are already equipped with a pre-installed thermal discharge safety device.
