The entire series of Skat boilers are single-circuit, and hot water supply is supplied by installing an indirect heating boiler.

Advantages and disadvantages of Proterm Skat boilers

Most of these disadvantages and advantages are inherent in most boilers operating on electricity.

Pros of Protherm Skat boilers

High efficiency
Easy to install
Unpretentious in maintenance
Eco-friendly
Doesn't require much space
Silent operation

Disadvantages of Skat series boilers

High cost of electricity
Dependence on power outages

Sometimes electric boilers are credited with shortcomings that are no longer relevant or were obviously incorrect; let’s look at some of them:

The boiler power is not enough to heat a house larger than 300 m2

This statement is incorrect, due to the fact that Skat boilers can be connected in a cascade to increase the heated area, if there is a shortage of 28 kW.

Frequent replacement of the heating element

Due to the fact that the heating medium is heated using a heating element, many believe that such a heating element will not last long, but you need to take into account the quality of the heating element itself and do not forget that it is not water that circulates in the system, but a coolant.

Installation of Proterm Skat boilers in a cascade

If a 28 kW boiler is not enough to heat the house, it is possible to install the Slopes in a cascade to increase the coverage of the heating area. When two boilers are connected in a cascade, the second boiler is controlled using a room thermostat, which is connected to the first boiler. This diagram will look like this:

Cascade connection of Proterm Skat boilers

The contacts of the room thermostat are connected to terminals 1 and 2 located on connector K8 of the main boiler, and terminals 9 and 10 of the main boiler are connected to terminals 1 and 2 of the slave boiler.

Only the Proterm Skat 28 kW and Proterm Skat 24 kW boilers can operate in cascade mode.

Guarantee

The warranty period for these boilers is 2 years.

A heating element

Depending on the power of the boiler, different numbers of heating elements are installed in them; in the R13 modifications, heating elements were installed in accordance with the following table:

Number of heating elements in Proterm Skat boilers

Operation from 220V and 380V network

Boilers with a power of 6 kW and 9 kW are capable of operating from a 220V and 380V network; boilers of higher power can only be connected to a three-phase 380 volt network.

But, given the fact that the average price per kilowatt in Russia is 4.5 rubles, the heating season lasts seven months, the amount will be substantial. The control panel is equipped with a function for storing parameters and adjusting the boiler power.

Liquid fuel. In this case, a gas double-circuit boiler is a more preferable option, since water heating for hot water supply and heating occurs in one device, and connecting additional devices is not required.

The cable cross-section, the power of circuit breakers and RCDs must be selected taking into account the power of the boiler and circulation pump. Operating instructions for Proterm electric boilers Using an electric Proterm heating boiler to heat rooms for various purposes is not so difficult, because the regulation and control system for an electric boiler is quite simple.

There are four heating elements in the heat exchanger with a power of 7 kW each. Automation allows the use of an electric boiler in conjunction with a load relay.

Components for boilers Proterm Skat

When purchasing a boiler, in addition to it, the manufacturer offers various accessories to expand the functionality.

Fuel type – natural gas is the most convenient and economical heating option. If it is unavailable, electricity and solid fuel are considered.
Purpose - the number of circuits depends on the requirements for the equipment - one is enough to heat the premises, and with two you can use hot water.
Placement option - equipment can be wall or floor mounted. The choice depends on the available space in the room.
Gas pressure - this parameter is important to ensure uninterrupted operation of the boiler.
Heat exchanger material – cast iron elements last longer than steel parts.
Type of ignition - piezo ignition is possible without electricity, but more gas is consumed. Electronic ignition is volatile.

When choosing equipment, the reputation of the manufacturer plays an important role. The Proterm company is one of the most respected and well-known companies producing thermal equipment.

Reviews

Andrey G. “I built a house, winter is just around the corner, I need something to heat it. I wandered around the Internet, read reviews, and decided to buy a boiler from the Slovak company Proterm. I chose the wall option based on the area of the house. The boiler with the beautiful name Cheetah model 23 MTV was the best choice. Well what can I say? It is controlled very simply with three buttons. The instructions are very clear and explain everything in detail. It makes a little noise, but it doesn't interfere with falling asleep. Very compact. Maintenance is very simple - just occasionally clean the dirt filter and wipe the dust from the boiler. It performs its functions without any problems. I didn't notice any shortcomings. I recommend".
Vasily V. “I decided to change my old gas water heater. And since in severe frosts there is often not enough heat from the stove, I decided to install a modern gas boiler with the ability to heat water. The choice was determined only by price. I took an inexpensive Jaguar 11 JTV from Proterm. The boiler turned out to be surprisingly silent, with a beautiful design. In 2 years it has never broken down. There are no shortcomings."
Vladimir U. “I have been working for 11 years in a service center servicing heating boilers, including gas ones. During this time, we had to install and repair all types of boilers from all companies that are sold in our stores. I can’t say anything bad about Proterm gas boilers. With proper installation and proper configuration, they work like a clock. But if the service specialists have neither the skills nor the experience, or the owners adjusted something on their own, then problems in the work and, as a result, bad reviews are inevitable.”
