LG launches residential air-to-water propane heat pump

South Korean electronics manufacturer LG has launched this week a new version of its Therma V R290 Monobloc residential heat pump.

“Our brand new Therma V R290 Monobloc air-to-water heat pump (AWHP) has been radically redesigned to help you install and maintain with speed, flexibility and simplicity,” the manufacturer said in a statement. “It is engineered to operate at peak capacity and efficiency, even in the harshest climatic conditions, with temperatures plummeting as low as -15 C.”

Hydrogen: Potential meets reality – where are the opportunities for solar industry

Don’t miss the session about hydrogen during our Roundtables Europe.

The hydrogen economy is coming, and it will be big. But when will the market develop, and what prospects will it open for the solar industry to increase revenues and find off-takers? We’ll dissect where hydrogen production works and why, where it falters, and where it’s commercially sound. We’ll dive into the heart of hydrogen production—the electrolyzers, and have a look at the different technologies, their expected cost degression, and whether colocation with solar plants is a reasonable opportunity. Finally, we explore PtX technologies, assess their development speed, and discover which electrolysis tech is gaining ground.

The new product utilizes propane (R290) as a refrigerant and has a global warming potential of 3. According to the manufacturer, it can achieve a flow temperature of 75 C and 100% heating output even at extremely low outside temperatures of -15 C, with the operating range reaching down to -28 C.

LG is offering the heat pump in four versions with nominal capacities of 9 kW, 12 kW, 14 kW and 16 kW. Its seasonal coefficient of performance (SCOP) is reportedly over 5.

The manufacturer said the heat pump can also be integrated with energy storage systems (ESS) to maximize the use of residential PV systems.

“Surplus energy can be stored in the ESS battery and diverted to the AWHP’s integrated water tank during the daytime, when solar energy production is at its peak,” it explained. “In the evening, when energy consumption is typically high, the ESS utilizes the stored energy to provide hot water and to power home appliances, boosting energy efficiency and energy self-reliance.”

Please inform LG that “harshest climate” is entirely subjective. In much of the Northern Prairies, especially in Canada, temperatures regularly go below -25C and do get to -40C and -50C. We would consider heat pumps when they are truly capable of handling these type of conditions.

[Waters in sunflower sprouts with liquid nitrogen.] Been tree farming long? I’ll go out on a condensation spike and guess saline water heat transfer isn’t the version you’d like as well as a whole clad working pulse pipe or two through walls or underground. It’s not as easy to ship, small carrier luck be with you.

Not a heat pump climate. Stick with the science.

Please tell us about the Reverse Heat Pump Cooler (HPC). Does it PumpOut heat in Hot Summers of 50°C , 100 Cubic Metre to cool down to 23°C in 50 minutes (3000 Seconds) & maintain at 23°C for 5 hours.. How many Kw required?
