The main heat exchanger rotted in a year and a half, I checked it with a magnet, it sticks. How could lively metal be used for condensation equipment??? The price of a new one is just outrageous, it's better to get a new boiler. They are not there Heat exchanger, made of regular metal priced at 20,000 UAH  Timur : use Protherm Puma Condens 18/24 MKV-AS/1 more than year |
The boiler was bought in a private house of 145 squares. It heats well, quickly, the pump works well, including underfloor heating (as far as I understand there are two pumps, because I clearly hear different noises, but this is not accurate). Heats up water very quickly and is very quiet. On frosty days, I turn on the temperature a little more, and according to the thermostat it is always 50 degrees. There is also a minus here - the gasket leaked after a year, I had to change and install a gearbox with a limit of 3 bar, because there were 7 bar in the system, and apparently it was not designed for such pressure from the outside. We have been using the boiler for a year. During this time he served him. Compared to a domestically produced boiler - ~ 30% more economical? with more capacity. It is possible to connect a thermostat, but probably all modern boilers already support this. Just the old boiler did not support. I note very high quality copper tubes, at all inputs and outputs. Well, a nice screen, looks modern. Economical and quiet, even at high power. Heats up water quickly. Cool look. The inlet rubber leaked. I read that this is a disease of these boilers, and it is better to put a gearbox on the input, with a limit of 3-4 bar / atmospheres. Which is what I did.

Gas saving boiler
The condensing gas boiler Protherm Puma Condens 18/24 MKV-AS / 1 consumes 12 – 15 percent less fuel than traditionally designed devices of similar power. Due to the use of the heat of condensation of water vapor, it has a high efficiency (107.8%) and reduced gas consumption (less than 2.54 m³ / h, if "stoker" is full). The built-in circulation pump with frequency speed control and modulating burner also ensure reliable and stable operation of the equipment in low power modes (from 6.6 kW).
Ease of setup and upgrade
The boiler is controlled and its operating modes are set using a touch panel with an LCD display. Thanks to the "block" eBus, any of the Protherm controllers or sensors, as well as compatible analogues that support the same standard, can be connected to the device. Therefore, the boiler can easily work in complex heating and hot water systems (including multi-stage water heating systems with elements such as solar panels or heat pumps).
Inexpensive condensing boiler for home heating and water heating
Protherm Puma Condens 18/24 MKV-AS/1 costs less than $900. This is a very "nice" price (by the standards of double-circuit condensing boilers). The manufacturer managed to reduce the cost by using simpler components (for example, the heat exchanger is made of aluminium, although other companies put more expensive stainless steel). But on the other hand, Protherm boilers are very unpretentious to the quality of water and gas and are not at all “capricious”. Therefore, this unit is perfect if you live in a region with hard water and "orange" gas instead of "blue".
