a good boiler, during electrical overloads, through a stabilizer, it works perfectly.
14 February 2011 
the boiler can be adjusted to a lower power setting, making it suitable for smaller areas. When the area increases in the future, it can be readjusted. It has automatic temperature adjustment without any sensors.
compact, as for such a model. very efficient. has all the necessary blocks (two circulation pumps, expansion vessels, air vents, valves, recirculation outlet, make-up).
to change the parameters manually, you need to scroll through all the data by pressing the MODE button affirmatively.

My opinion about the Protherm Bear KLZ 40 floor standing unit is positive
15 December 2018 
The boiler is quite compact, if this word is applicable to a floor-standing boiler in principle - all equipment fits in one housing. There is even a built-in boiler with a capacity of 90 liters - convenient, no need to spoil the room by placing an indirect heating boiler. The Bear's heat exchanger is made of cast iron - an excellent material in terms of heat transfer, although not the lightest. I liked the boiler control system - a large bright display, convenient buttons, everything is intuitive. The Bear is quite simple to install; a team of two engineers completed the task in a day, which was a pleasant surprise. Otherwise, everything is fine: there are no problems with heating, there is hot water in the house.
thoughtful design and simplicity

Hello. I’ve been using it for four years now. No complaints. The hot water never runs out. In the spring I turn off the heating. Hot water supply all year round. Convenient adjustment.
I like all the options.
