Stepless modulation

Since 1994 Heliotherm has diligently researched and developed the modulating heat pump technology, having set a milestone in leadership in this field through many years of experience, it has now become proven technology.

Heliotherm’s stepless modulation technology opens up new possibilities for high efficiency heat pumps. Additionally, through the soft-starter phase the heat pump is preserved giving it a longer lifespan.

Intelligent cost saving > tomorrow's technology > here TODAY:

Higher heat output with decreasing outdoor temperatures
Higher efficiency and up to 20 % less energy costs compared to conventional heat pumps
Less power consumption due to modulating peripherals
Improved efficiency and higher seasonal performance factor (SPF)
Flexible use of living space through intelligent control technology: unused rooms can be excluded from the heating system
Regulating control detects an external heat source (e.g. stove) and automatically reduces the heat pump capacity > lesser operating costs
