Heat pumps for home

Heating, cooling, and hot water with minimal costs and without harming the environment.

Key features and benefits

Air-water heat pumps

Hajster NEBO split

Air-to-water heat pumps use air as a heat source, making them the simplest to install. They do not require interaction with the ground or groundwater. The technology provides three functions at once: heating, cooling, and hot water heating. The execution is "split" - the external and internal units are connected by a refrigerant line.

What our clients say

"Clever Bloom installed three Prana units at one of our partner shops that handles transportation operations, with an adjacent lab that had been struggling with humidity and ventilation issues. During the winter, opening windows made the lab cold and uncomfortable to work in. Their smart heat exchangers were in fact great solution. The team did an excellent job with the installation, and within a week, the difference was clear—no more condensation on windows, and the air quality was significantly improved. Recommend!"

Constantine Gurnov

“Clever Bloom Company recently installed 2 Prana units in my clinic, and the results have been remarkable. Being an older lower-ground property with limited ventilation, the air quality was previously less than ideal. However, the device has made a significant improvement, and even my patients have noticed the difference. Highly recommend!”

Dr. Lana Vaitovich

“Viktor and his team were great. They installed the units in a single day, they cleanup as they were working, kept me updated on their progress, and were very helpful in explaining how they work. We had two units installed, we are enjoying the clean fresh air and are extremely happy with the performance of the units. We were able to get the units perfectly setup the way we wanted with schedules. The auto functions are a life saver!.”
