Innovative Wall-Mounted Heat Pump Offers Easy Climate Control
A new, all-in-one climate control system has been introduced by MRCOOL, a company based in Hickory, Kentucky. This innovative device operates by simply plugging into a standard 115-volt electrical outlet and does not require a large, external condensing unit, offering a streamlined solution for various spaces.
The MRCOOL Monoblock MTHP is specifically engineered to provide both heating and cooling for smaller areas, such as garages, dedicated home workspaces, accessory dwelling units, sunrooms, and compact residences. It caters to homeowners seeking localized climate management who may lack the necessary space or authorization for a conventional mini-split system installation.
What distinguishes the Monoblock is its integrated design, housing the complete refrigeration mechanism within a single unit that mounts directly onto a wall. Traditional mini-split systems typically involve an indoor air handler connected to an outdoor condenser through refrigerant lines. In contrast, the Monoblock combines these elements internally, removing the need for refrigerant line connections and an outdoor equipment pad.
While designed for simplicity, the unit does require access to an exterior wall. Its installation involves creating two openings in the wall for external air intake and exhaust, along with a smaller aperture for condensate drainage. Therefore, while it is user-friendly, it is not simply a 'plug-and-play' device that can be placed on the floor.
Weighing approximately 93 pounds, the installation of this unit is likely a task that will require at least two individuals.
The Monoblock system provides a cooling capacity of 10,000 Btu per hour and a heating capacity of 9,000 Btu per hour, making it suitable for conditioning a single room rather than an entire dwelling. Its dimensions are approximately 39 inches in width, 23 inches in height, and 8 inches in depth.
Equipped with an inverter-driven compressor, the unit can modulate its output rather than constantly cycling on and off. MRCOOL rates its cooling efficiency at 15 SEER2 and heating efficiency at 7.5 HSPF2. These figures are commendable for a compact, integrated unit, though they may not match the efficiency of some conventional ductless mini-splits.
MRCOOL states that the unit is capable of operating in external temperatures ranging from 5°F to 113°F. The lower operational limit suggests that it is not intended as a substitute for cold-climate heat pumps in regions where winter temperatures frequently fall below 5°F. However, it presents a viable alternative to electric resistance space heaters in more temperate climates. Given that heat pumps transfer heat rather than generating it directly, they can deliver more warmth using the same amount of electricity.
Beyond its primary functions, the system also offers cooling, dehumidification, and fan-only modes. The manufacturer claims noise levels range from a quiet 32 dBA on its lowest setting to 46 dBA on its highest.
Christian Rea, MRCOOL's director of sales, highlighted the Monoblock MTHP Series' ability to provide immediate climate control in spaces that have historically been challenging to regulate. He noted that by eliminating the significant costs and complexities associated with an outdoor condenser, installation time is reduced by 60% compared to traditional central systems.
Because the refrigerant circuit arrives completely sealed, homeowners are spared the need to handle refrigerants, connect pre-charged lines, or engage an HVAC professional for system charging. Its 115V plug allows it to operate from a standard household outlet, potentially bypassing the expense of installing a 240V circuit or upgrading an electrical panel.
Nevertheless, MRCOOL advises that installation must still adhere to local building and electrical codes. Making two substantial openings in an exterior wall necessitates thorough planning to avoid compromising existing wiring, plumbing, and structural elements.
Additional features include a remote control, an LED display, optional Wi-Fi connectivity via the MRCOOL Connect app, compatibility with Alexa and Google Assistant, and a self-evaporative condensate system equipped with an overflow alarm and automatic shutoff. The Monoblock utilizes R-32 refrigerant, which possesses a lower global warming potential than the R-410A refrigerant commonly found in residential air conditioners and heat pumps.
The MRCOOL Monoblock is now available for pre-order through authorized vendors. Current pricing varies among retailers, with listings spanning approximately $1,370 to $1,550. Some retailers anticipate an August 31 release date.
This new climate control device from MRCOOL signifies a substantial advancement in accessible home comfort solutions. By integrating all essential components into a compact, wall-mounted unit and operating on a standard electrical outlet, it offers a practical alternative for zoned heating and cooling, particularly appealing to those with space limitations or specific installation constraints.
