THERMAL Plus CH + DHW
THERMAL Plus monoblock heat pumps are energy efficient devices which draw energy from the air and use it to heat or cool the building and prepare heat utility water. They can be used in single-family houses as well as commercial buildings. Heiko’s heat pumps are advanced devices, which guarantee efficient and safe operation.
THERMAL Plus heat pumps are KEYMARK certified. It is a European mark confirming the conformity of products and services with European standards. Whilst the CE marking proves compliance with minimum legal requirements, KEYMARK provides the consumer with a real added value: tested and certified adherence to uniform European Quality Standards.
A product can only be KEYMARKed if it has been previously tested and certified by a neutral, independent and competent body.
Heiko heat pumps are included on the German BAFA funding list. They constitute a key element of Germany’s strategy for sustainable energy production and environmental protection. Due to their high efficiency and minimal impact on the natural environment, they present an attractive alternative to traditional heating systems based on fossil fuel combustion. Therefore, when purchasing them, one can expect attractive financial incentives from German government programs.
Thanks to the available funding programs, Germany is becoming an increasingly attractive market for the development and utilization of heat pumps. The tremendous success of the BAFA funding program only confirms this. HEIKO is a proven choice in the European market.
Hydraulic module – ALL IN ONE MONOBLOCK
The compact design of the hydraulic module with the integrated 250-litre DHW
storage tank is ready to use out of the box. No additional system components must
be purchased, and no extra installation space is required for a DHW tank. The module
enables easy and safe hydraulic connections.
Two heating circuits
A standard THERMAL Plus heat pump can be confi gured to supply different heat
loads at the same time, like a radiator space heating system and an underfl oor
heating system. With two heating circuits, the temperature in different heat loads
can be managed separately; in practical terms, different temperature settings can be
made for the radiators and the underfl oor heating.
Wide temperature range – reliable operation in all conditions
The Heiko heat pumps are reliable units which operate from -25°C outdoors and can
heat DHW to 55°C.
Wi-Fi control
The standard Wi-Fi control available improves the comfort of operating the Heiko heat
pumps. An easy and intuitive app for mobile devices lets you monitor the unit status,
display the current energy consumption, and modify the temperature settings.
Modern control panel
The integrated control panel enables easy and quick changing of operating parameters. The controller menu is available in several language versions.
Silent operation
The Heiko THERMAL Plus heat pumps have DC motor fans, a well sound-insulated refrigerant compressor, and an optimised air fan design to ensure very quiet operation already at 52 dB(A). The units can also run in a quiet mode for improved comfort at work or while resting.
Automatic weather control
The Heiko THERMAL heat pumps operate in an automatic process controlled by weather temperature curves. In practice, this means that the heat pump operation is adapted automatically to actual weather conditions without any human intervention.
Frequency converter technology
Frequency converter technology allows cost-effi cient operation of the heat pump without sudden voltage frequency surges of the compressor. This provides energyefficient and quiet operation. The units have A+++ energy rating.
