Protherm Panther 25 KTO 24.6 kW
 | Outdated Product Gas single-circuit heating boiler with an open combustion chamber. Designed for wall mounting in separate boiler rooms with a mandatory free supply of fresh air. Manufactured in Slovakia in a facility owned by the Vaillant Group. It is the middle model in the Protherm Panther line, the products of which belong to the heating equipment of increased comfort. It is intended for the organization of heating of inhabited, commercial, municipal and industrial premises. It is positioned as a product of the upper part of the middle price category. With a useful heat output of 24.6 kW, the Protherm Panther 25 KTO boiler is able to serve rooms up to 184 m2. It is equipped with a built-in circulation pump, the pressure of which is sufficient to service a two-story cottage. It should be noted that for...the safe operation of the apparatus, a full-fledged chimney system is required, which must meet a number of mandatory fire safety requirements and provide a stable natural draft that completely removes gas combustion products. The boiler is equipped with a microprocessor control system with a display, which makes it easy and convenient to control the operation of the heating system and change the necessary parameters. Thanks to the support of eBus data transfer technology, it can interact with a wide range of Vaillant thermostat modules (including those with remote control). |

Yes, heating with gas is now expensive, and if I had a domino of 400-500 square meters, it would make sense to look for alternative options. I need to heat a modest half of the house, consisting of four rooms and a kitchen. For such an area (about 80 square meters), a heavy-duty boiler with a high gas flow rate is not needed. Moreover, in the summer I invested heavily in the thermal insulation of the walls, and now, with this new boiler, in cold weather, my gas consumption has decreased by almost half compared to last year. This boiler has many advantages. Firstly, compared to the previous one, it has a much higher efficiency of gas use. Passport efficiency is 91 percent, which is almost 5% better. The boiler is single-circuit, that is, relatively simple and reliable. Equipped with a relatively quiet circulation pump. Its combustion chamber is of a closed type, that is, the boiler has a system for the forced removal of combustion products. This made it possible to make a simple and short chimney, which would not be enough with natural draft. The boiler is equipped with a stainless steel burner, which, thanks to a modern microprocessor control system, can change the strength of the flame, changing the power of the entire system. Thus, the device can produce from 7 to 13 kW of heat. Of course, there are many protective systems. The boiler is not afraid of a drop in gas or water pressure, flame extinction and other typical troubles. The fan turbine is not too loud, but is clearly audible. Therefore, I would be careful not to mount such a boiler directly in a living room, I do not like extra sounds at night. In active mode, it consumes something around 120-130 watts of electrical power, which is a lot and will require a more powerful uninterruptible power supply than I had before. |
