Caldameg 4.5kW Heating System

CALDAMEG 4.5kW Heating System-01

There is a growing interest and need to deal with energy sustainably. People are searching for solutions to accelerate the energy transition, reduce gas dependency and improve energy labels in existing buildings. Time is running out! Global-E-Systems produces and develops energy systems based on renewable energy and is introducing the accelerator for energy transition: the Caldameg™ heating system, which is a complete replacement of the traditional gas-fired combi boiler.

The Caldameg™ heating system is a patented “Smart Heat Pump Buffer Concept” and is specially designed for space heating and hot water supply. The system provides a cost-effective and sustainable solution to replace the traditional gas boilers. By installing the Caldameg™ heating system, the energy label of a home will improve immediately. This solution is also an ideal addition for “zero on the meter” projects and a catalyst for the transition to “all electric” buildings.

How does it work?

The Caldameg™ heating system is a highly efficient 4.5 kW CO2 heat pump (air / water), combined with a 264 liter PCM buffer tank. The Phase Change Materials in the buffer enable a large amount of heat storage, which can be used for hot tap water and to heat the home. The CO2 heat pump is able to produce water of 80°C, regardless of the outside temperature and requires a relatively small amount of energy on an annual basis. When the house is conveniently located, it becomes possible to make the system energy neutral In combination with several solar panels.

Installation

The existing installation in the house does not require modification: just replace the boiler, with Caldameg™. The CO2 heat pump for outdoor installation can be placed on flat roofs, against the façade, in the garden et cetera. Prefab in-roof constructions are available for installation on sloping roofs. The buffer tank can be easily placed on different locations inside the house. For example, the buffer tank can replace the boiler in the same location. It is also possible to adapt the shape of the buffer to the situation in the home. It is recommended that the installation is performed and maintained by an authorised installer (STEK certification is not a requirement).
