Simpler installation and better fl exibility for existing homes


Scalable heating for larger


buildings


Swedish heat pump manufacturer Qvantum has launched a new 50kW air-to-water heat pump, the QA50, designed for multi-residential and light commercial developments in the UK. Paired with the Qvantum QG water-to-water apartment heat pump, the QA50 enables a complete ambient loop solution for residential developments, delivering effi cient, low-carbon heating, hot water, and cooling at both building and apartment level. With a wide operating window,


Daikin has launched the Daikin Altherma 4 Hydrosplit (Altherma 4H), the fi rst heat pump in its next-generation Altherma 4 series. The new range introduces a redesigned outdoor unit with a modern full-width black grille, Quiet Mark-certifi ed low-noise operation and next-generation controls, led by the new MMI-4 colour touchscreen controller. Designed for existing homes,


the system provides heating, domestic hot water and cooling. Flow temperatures reach up to 70°C for EPSKS models and 65°C for EPSK models, allowing it to work with standard radiators. It operates at outdoor temperatures as low as -28°C and achieves an A+++ energy label for space heating at both 35°C and 55°C fl ow temperatures. The hydrosplit design keeps the


refrigerant circuit sealed within the outdoor unit, with only water passing between the indoor and outdoor units.


Altherma 4H uses R-290


refrigerant, with a global warming potential of 0.02. Safety features include a gas separator, sealed switchbox and gas sensor with automatic fan operation, helping minimise the exclusion zone around the outdoor unit. Indoor options include a wall-


mounted hydraulic unit or an integrated fl oor-standing model with a domestic hot water tank. Installation features include factory-fi tted anti-freeze valves and simplifi ed wiring, while improved component access is designed to make servicing easier. The MMI-4 controller has a 5in colour touchscreen. Daikin’s DCS-R online portal allows installers to monitor up to 190 operating parameters and adjust settings remotely. The system also supports the Onecta app, digital TRVs, Modbus/API connectivity and over- the-air updates. ◼ phamnews.co.uk/1126/32


the QA50 is ideal as the primary energy source for low-temperature ambient loop systems. Its compact dimensions and modular design allow multiple units to


High output,


modular design A new air-to-water heat pump using R290 refrigerant has been launched by Elco, part of Ariston Group, for commercial heating applications. The Aerotop Evo P is available in


seven models, delivering outputs from 40 to 84kW, with up to 1,344kW possible in cascade. It achieves a seasonal coeffi cient of performance (SCOP) of 3.4 to 3.7, supplies water at temperatures up to 75°C and operates at outdoor temperatures down to -20°C. Designed for modular


installations, the system features an inverter-driven fan with


While designed primarily for


multi-residential ambient heat loop applications, the QA50 is also eff ective as a standalone heating and cooling system for a wide range of light commercial buildings, including offi ces, leisure facilities and mixed-use developments. In this setting, its modular design and scalable capacity make it a fl exible, low-carbon solution that doesn’t compromise on performance or occupant comfort. The QA50 operates with the


be combined, creating a scalable solution that can be tailored to project requirements while maximising available plant room space. Its environmental impact is also minimised through the use of a natural refrigerant, R290.


QC PRO controller, providing centralised management of multi-unit systems through a single intelligent platform. This enables housing providers and facilities managers to integrate and manage heating, cooling, hot water, and system components, simplifying system control, improving operational effi ciency and performance, and providing visibility across the entire heating system. ◼ phamnews.co.uk/1126/33


three selectable acoustic settings, a treated copper-aluminium coil and a heated drain tray to prevent condensate freezing. A leak detector is fi tted as


standard, and a dedicated hydraulic kit supports installation and building management system integration. ◼ phamnews.co.uk/1126/34


Monobloc range expanded


The expanded monobloc heat pump range from LG off ers additional capacity options for residential and commercial buildings, with new 12, 14 and 16kW models and a standard series with indoor control units from 5 to 16kW. The systems feature a 6.8in colour touchscreen, built-in Wi-Fi and sound and vibration reduction. They can heat water to 75°C at outdoor temperatures as low as -25°C and use R290 refrigerant, which has a low global warming potential. The range achieves an A+++ energy rating. The indoor hydro unit includes a back-up heater, three-


way valve and expansion tank. For higher-demand applications, such as large homes,


schools, offi ces and care homes, the standard series also supports cascade control, allowing up to eight units to be monitored and controlled together. If one unit encounters a fault, the others can continue operating to help maintain heating. ◼ phamnews.co.uk/1126/35
