UK Heat pump manufacturer Daikin has expanded its high-efficiency, Multi+ range to cater for larger households and medium-sized businesses with a new outdoor unit that can be connected up to four indoor units. 

The company said the new outdoor unit and DHW cylinder offers greater flexibility and requires minimal space, as well as being quick and easy to install. According to the manufacturer, this makes it an ideal replacement option for DHW and space heating systems where air conditioning is also a requirement. 

It is available with a normal capacity of 6.8kW or 9.0kW in cooling and 8.60kW or 10.00kW in heating. It boasts impressive energy efficiency ratings of A+++ for cooling, A++ for heating and A+ for domestic hot water. This makes it a strong contender for larger domestic and light commercial applications, the company said. 

Households can use the new unit to support up to four indoor units in addition to a DHW cylinder, one more indoor unit than the current system allows. The small four-port system was launched last year, with current range consisting of three models, a four-port 5.2kW and the above models, plus the two cylinders, 120L and 230L. 

The manufacturer said the increased capacity ensures greater flexibility in tailoring indoor climate solutions to meet individual needs. The variety of indoor units, including wall-mounted, floor-standing and ceiling models, aim to provide its customers with aesthetic, functional and financial choices to suit their space. 

In addition to the larger outdoor unit, Daikin has launched a new 230L floor-mounted DHW cylinder to complement the existing 120L wall-mounted DHW cylinder, giving customers the option to select the best fit for their household or business requirements. 

Multi+ is supported on Daikin’s Onecta app, which is compatible with Amazon Alexa and Google Assistant, allowing the scheduling, control and monitoring of individual indoor units and the domestic hot water system from anywhere, at home or away. 

It is also compatible with Daikin’s Easyzone system, allowing multiple zones to be served by a single fan coil, effectively increasing the number of rooms the unit can service, making it a more viable and cost-effective solution, the company said. 

A company spokesperson said the Multi+ heat pump has been engineered to provide the highest standard of reliability and efficiency, incorporating several innovative design features, driven by advanced technology. 

“This includes an innovative fan design, featuring specially shaped fan blades that significantly reduce sound emissions and lower power consumption, all concealed behind an elegant front grille,” the spokesperson said. 

“A high-efficiency swing compressor continuously adjusts the system’s cooling and heating output to maintain designed room temperatures.”

He also explored the initiatives major container ports and terminals have launched in order to ship vital goods across the world without polluting the environment.

Since then, he has reported heavily on the impact made by environmental, social, and governance (ESG) practices on the supply chain of minerals, with a particular focus on rare earth mining in Africa.

As part of this, in 2022 Max visited mines and ports in Angola to hone in on the challenges being faced by one of the world’s biggest producers of rare earth minerals.

His most recent sustainability-related work came much closer to home, as he investigated the eco-challenges faced by independent retailers in the UK, specifically looking at how they can cut emissions and continue to thrive.
