i like its design - no need to worry about where to hide it. We have a two-phase meter - set it to 25 degrees at night and 18 during the day. It maintains the set temperature. I like everything about it. Convenient to program from the app for the week. not found use Teknix ESPRO 15 kW week i recommend it should buy |
We bought it for our parents' house as an addition to the solid fuel one. Installation and connection went smoothly. We started it up and everything works. It heats the medium quickly, isn't noisy, and has a wonderful modern design. The app was a pleasant surprise - set it up for the week and then forgot about it. You can save significantly since a multi-tariff meter is installed. We're pleased with the purchase and hope it works reliably for a long time. The 2-year warranty was also a plus. Quick installation and connection, convenient app, ability to program the temperature for the week, nice design a few times it kicked me out of the app  Yana: use Teknix ESPRO 9 kW less than month |
I bought a 15 kW model with a frequency-controlled pump for electric heating of a 120-square-meter townhouse, with underfloor heating and 3 radiators. It has worked for one season, and I am generally satisfied. It operates quite quietly; you can hear the clicking from switching between heating elements, but it’s not disruptive. It quickly heats the water in the system, looks good, and the heating professionals praised the internals. The house is built from gas blocks and well insulated, so 15 kW power is with a large reserve. I generally use it at a power of 7.5 kW, which is adjustable in the app. The app itself is not bad, but the programmer from 0000 for 3 hours does not allow for adequate use of the night electricity tariff. I didn't notice any glitches with the app on the iPhone; everything except for the programmer is organized/drawn well. There’s also control on the boiler itself, which is quite convenient, but I practically don’t use it, as it’s easier with the app and there's no need to go to it. Thanks to the frequency-controlled pump, you can use thermostatic heads on the radiators, and if all are turned off, the pump just shuts down, and the boiler does not consume electricity. Convenient control, fast water heating, quiet, pleasant design The programmer's ill-conceived intervals  Valeriy O.: use Teknix ESPRO 15 kW more than year |
