Indoor Heat Pump Fits Apartments With No Outdoor Space

For years, apartment residents watched their suburban neighbors upgrade to efficient heat pumps while strict building codes and lack of outdoor space kept them stuck with old heating systems. That barrier just crumbled.

Midea launched an indoor heat pump designed specifically for spaces where traditional systems won't work. The unit needs only two air ducts running through a wall or roof, eliminating the bulky outdoor equipment that building managers often ban.

The H-Pack system targets retrofit projects across Europe, particularly in apartment buildings and terraced houses where outdoor installation is impossible or restricted. At just under three feet wide and 172 pounds, it fits into tight mechanical rooms and closets.

The technology integrates with existing radiator systems without major renovations. Installation follows a simple six-step process using guide rails and brackets, connecting directly to current heating loops. Homeowners can upgrade to clean heating without ripping out walls or replacing their radiators.

Performance matches larger systems despite the compact design. The unit delivers up to 4.45 kW of heating power while achieving A+++ energy efficiency ratings. It runs in temperatures from negative 20 to 35 degrees Celsius, covering most European climates.

The system uses propane as a natural refrigerant, supporting Europe's push to phase out synthetic greenhouse gases. Sound levels stay at a quiet 34 decibels indoors, barely louder than a whisper.

Smart features let the pump talk to solar panels and grid signals, automatically switching between energy sources to minimize costs or carbon emissions. The touchscreen interface manages multi-zone heating, domestic hot water up to 75 degrees Celsius, and even cooling during summer months.

The Ripple Effect

This innovation could accelerate clean heating adoption in cities where half the population rents apartments. Building owners who previously avoided heat pump conversions due to installation complexity now have a simpler path forward.

The ability to pair with existing boilers in hybrid configurations means even cautious property managers can start transitioning without abandoning backup systems. As more buildings make the switch, urban air quality improves and heating costs drop for residents who need relief most.

When clean technology finally fits the spaces where people actually live, entire neighborhoods can join the climate solution.
