Heat pumps HEIKO THERMAL Plus CH+DHW

Heat pumps

Monoblock with hydraulic module and integrated DHW storage tank

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.

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.
