x-buffer expansions

Storage charging assembly

The storage charging assembly is available in different versions. The components are already pre-assembled on a platform which can be installed directly on the x-buffer layered buffer storage unit and which is supplied with the corresponding insulation. Alternatively, the pump group can also be used for wall installation. A switchover valve ensures a switchover between domestic water heating and room heating.

Heating circuit assembly

The “unmixed heating circuit” assembly consists of a circulation pump and the corresponding shut-off devices. The “mixed heating circuit” assembly also has a mixer. These components are already pre-assembled on a platform which can be installed directly on the storage unit or a wall and which are supplied with the corresponding insulation.

x-buffer fresh water station

It is the ideal supplement to the x-buffer layered buffer storage tank and guarantees hygienically clean domestic hot water. Designed as an energy-friendly flow heater.

The heat energy generated using the x-change heat pump can now be used in different ways to provide the domestic hot water. It is vital that the domestic hot water is kept completely hygienic. A simple and, above all, cost and energy efficient secure option is the new x-buffer heat storage tank which in conjunction with the fresh water station always ensures a supply of fresh, hygienically clean domestic hot water.

Characteristics

  • Hygienically optimal heating of domestic water: The domestic water is not heated until it is required, which always ensures a fresh an hygienically clean supply of domestic hot water
  • No domestic water tank required any more
  • Electronic control for a constant domestic water temperature which is integrated in the insulation
  • Electronic protection from scalding (with connected circulation)
  • Timing, modulation, or switching the pump off possible from the controller
  • Completely pre-installed and wired up
  • High quality stainless steel panel heat exchanger
  • Circulation pump operation time and temperature controlled (optional)

x-buffer solar heat exchanger

With the Kermi solar heat exchanger it is quite simple to use solar energy to heat hot water. Because with the solar heat exchanger, a thermal solar panel system can optimally charge the x-buffer layered buffer storage unit.

The layering process (primary side) in the x-buffer layered buffer storage tank uses the thermosyphon principle to ensure that the different temperatures are always at precisely the right temperature layers for the x-buffer layered buffer storage unit. With solar panel systems, this layer charging is very important because depending on the weather, it produces more or less heat energy per day. To optimally use solar energy, the energy from the first hours of sunlight are used to heat the top storage area which includes the zone for heating domestic water. In later hours of sunlight, the middle and bottom area of the storage unit are heated as well. This layering function can only be achieved in conventional storage systems with complex electrical closed-loop control and control technology.

The Kermi x-buffer layer storage buffer tank in contrast in combination with the external heat exchanger, has a system which achieves optimal layering simply by using gravity. This means that thermal solar panel systems can be used best at low temperatures.

5 year system warranty

Finally the new Kermi heating system has been installed. Or the Kermi ventilation system. Nothing left to stop you feeling cosy at home. With our 5-year system warranty, we are happy to prove the quality of our products and our service promise to you.

Just three steps to a 5 year system warranty:

1. Have the Kermi system installed by a specialist company
2. Have Kermi Customer Service commission the system (or in the case of ventilation systems, a specialist company)
3. Annual servicing by Kermi Customer Service or by a specialist company
