Midea presents 4.5 kW residential heat pump
China-based heating specialist Midea has developed a new indoor residential heat pump for residential applications.
“CirQHP Indoor Hybrid is a compact indoor heat pump that removes the need for an outdoor unit,” the manufacturer said in a statement. “This feature provides greater flexibility in installation options, making it an excellent choice for homes located in close proximity to neighbors or townhouses.”
The new heat pump has a heating capacity of 4.5 kW and uses propane (R290) as the refrigerant. It can reportedly operate with temperatures down to -20 C and be connected to existing radiators and underfloor heating.
In colder seasons, the system uses a gas boiler to support heat pump operations, providing heat and cost savings, according to the company.
“The product can automatically switch between gas boiler and heat pump for the most cost-efficient mode for end-users, and the integrated energy consumption monitor helps to keep an eye on costs,” Midea stated. “The system swaps between two energy sources following the end-user preferences: ambient temperature, real-time energy costs or environmental mode for a reduced carbon footprint.”
The system is currently being presented at the IFA exhibition in Berlin, Germany.

Great, particularly in colder areas where the temperature is less than the rest of Uk: Scotland.
Bring it on!
Given a heat pump is effectively absorbing, upgrading and transferring heat from one location to another, how does this actually work without an outdoor unit? Is it circulating air via the twin wall of the boiler flue? If so, the peak output of the heat pump will be very low.
I would assume, it works in the same way as a bunch of the Innova and their rebranded products (e.g. Powrmatic) where you have two holes in the wall, one for taking in outside air, the other one for expelling the heated/cooled air from the heat exchanger/refrigeration cycle.
