Condensing technology

Overview of the Protherm condensing boiler line
From the standpoint of the user, the most important characteristics of a good condensing boiler are high efficiency and ease of use, as well as a long service life and simple operation. To make the plumber's work easier, the boiler should be easy to connect and start up.

Protherm engineers consider all of these requirements when designing new equipment. And it is evident in the individual features of the condensing boilers we offer, from the smallest wall hung boilers to compact floor standing boilers. Furthermore, each has a distinguishing characteristic which allows for suitable placement and meets the requirements of the investor.

Solid cover, small dimensions
The smallest condensing boiler that Protherm offers is the Panther Condens boiler, available in a heating-only version with an output of 12 kW to 24 kW, or in the version with through-flow DHW heating with a 24 kW output and a maximum heating output of 18 kW. The boiler has small dimensions, allowing it to be installed, for example, in the kitchen. It is easy to operate using the control panel located directly on the boiler by using a room thermostat with digital communications. All settings changes on the thermometer are instantly communicated to the boiler. For instance, as soon as the DHW temperature settings are changed on the thermostat, they are saved in the boiler's memory. This is a convenient solution, which makes operating easier, especially if the boiler is in a different room or in a separate boiler room.

Furthermore, in order to achieve higher efficiency, the boiler has been equipped with an automatic outdoor temperature monitoring system, which – after an outdoor temperature sensor has been installed – optimizes equipment operation by adjusting the temperature of the boiler's heating system water to the current heat loss of the building. Thanks to that, the boiler can work at lower heating system water temperatures and can intensively cool combustion gases, from which it gains additional energy, further lowering gas usage.

The Panther Condens boiler is simple and easy to start up. A mounting console for hanging the boiler on the wall is part of the boiler delivery. If the connection platform is used, which contains not only hot water shut-off valves, but also a cold water and a gas valve, it need only be fastened to the wall and then connected to the installation's valves and fittings. This solution significantly speeds up installation, makes access to all the pipes easier, and eliminates the need to measure distances between individual connections. After the installation is connected to the platform, it is enough to put the sealing material on the platform connections, install the boiler and tighten the connecting elements. Starting up the boiler then becomes a very easy task for a qualified service technician, because he has the proper service codes, which allow him to automatically bleed the boiler and run the boiler at minimum and maximum capacity. That makes quick analysis of the combustion gases easier, leading to desired burner settings.

Very high comfort in DHW heating
Tiger Condens is the newest Protherm boiler; it is a wall hung condensing boiler with a built-in layered hot water tank with a capacity of 42 litres. This boiler is used in cases of high water usage (for example when servicing two bathrooms) and the investor wants to save space in the boiler room. This is possible thanks to the high maximum capacity of these boilers (25.5 kW), which allows 14 litres of water per minute to be heated with through-flow technology. Thanks to this it is possible to supply two standard showers simultaneously. When a sudden increase in draw off occurs – such as when using three showers or filling a large bathtub – the boiler uses energy stored in its DHW tank. The water in the DHW tanks together with that heated with the through-flow technology achieves a flow of up to 210 litres of DHW over 10 minutes. To gain such a quantity of hot water in a different fashion, a tank with a capacity of at least 200 litres is needed. By using a Tiger Condens boiler, you can save considerable space in the boiler room and better use your interior space. That is an important characteristic, especially with today's high building cost per m2. It also helps that the boiler contains practically all components necessary in the boiler room, notably safety valves, heating system water (HSW) and DHW installation valves, trap, pump, and SHW and DHW filter.

Before deciding to install this boiler it is, of course, necessary to consider whether the maximum heating capacity of 18 kW (25.5 kW for DHW heating) will be sufficient. You should also consider whether you have the option to install the wiring for the room thermostat and outdoor temperature sensor. If this is not possible, a wireless room thermostat (remote control) and a wireless outdoor temperature sensor can be used. In summation, using a Tiger Condens boiler means having the most options and the simplest installation.


Generously equipped and low maintenance costs
The last and largest of the Protherm condensing boilers is the floor standing boiler Lev 30KKZ, with a 25 kW output and a built-in DHW tank with capacity of 95 litres. Just like other Protherm equipment it has a high efficiency and it allows you to draw off up to 200 litres of DHW at any one time. Its installation is also very simple, because all the necessary components can be found within the boiler and it is enough to connect it to the heating, water and gas systems.

The Lev 30KKZ boiler comes with a generous set of features: a stainless steel heat exchanger, DHW tank with protective anode, trap, two safety valves, intake and outlet valves, one pump, electronic control panel, built-in system to adjust the HSW temperature in response to outdoor temperatures, three-way valve, and expansion tanks for HSW and DHW. This boiler also comes with many automation options. In addition to the option of regulating the boiler with a room thermostat, you can use a switch clock to control DHW heating and decrease output at night. It can be said that it is a floor standing boiler of small proportions (only 155 x 54 x 57cm), with a generous set of features and high output (up to 200 l DHW/10 min), whose design makes it suitable even for the interior of a flat.
