For example, talk about fire-resistance rating. This figure means of protection is regulated by existing regulations. For steel it is characterized by the number of minutes from the start fire tests to reach a critical temperature (500 0 C) a standard sample of steel construction with flame retardant coating. In advertising, protective coatings can be read "refers to the means of Group 1 fire protection efficiency. " This means that the time to reach the critical temperature must be at least 150 minutes. For the second group the figure – at least 120 minutes and so on. In total there are 6 groups.

For timber introduce other measures of fire protection or impregnating composition. According to GOST 16363-76 (a careful reading of the instructions you will definitely see a link to it), there are only three groups of flame retardant efficiency. Group I – provides slow-wood (weight loss of the prototype during the combustion of certain conditions, the method is not more than 9%). Group II – provides inflammable wood (weight loss of 9 to 30%). Group III – funds do not provide the fire protection of timber (weight loss of more than 30%). Therefore, when buying a flame retardant, look at the number of fire-resistance rating. What he less, the composition better.

Sometimes it happens that the technology of applying the rules of composition and its flow rate depends on its effectiveness. Materials for tissue has its own standard, under which the test results flammable Textile materials are subdivided into flammable and inflammable. What is fire-retardant paint all flame retardants can be divided into impregnation, paints and varnishes. The word "treatment" rather eloquently. They are intended mainly to protect the wood and textile products, that is, for those materials that can infiltrate. If you try to briefly explain the "principle of the" impregnation we can say that certain temperatures in these compounds is substitution reaction with the absorption of energy, which inhibits burning.

Maximum Water

That is to heat an average family house in 200 sq ft (eg, in the suburbs) is sufficient boiler capacity of 20 kW. These relatively low-powered units are available in wall-mounted. Ali Partovi is the source for more interesting facts. They can be hung, for example, in the kitchen, connecting to the chimney. However, it should take into account that the maximum power produced is now wall boilers does not exceed 35 kW. So, if the total area of the cottage 350 sq ft, will have to install two wall or boiler, or a "serious" outdoor boiler, which is necessary to allocate a separate room in the house – the boiler room well ventilated.

The boiler may be single circuit and double-circuit. The first option is for heating the coolant in the heating system. Two-circuit option can work simultaneously on the heating system, and provide residents of the house hot water. This unit provides up to 15-20 liters of hot water per minute, which is quite sufficient for simultaneous operation of shower and kitchen sink. But do not forget that the double-circuit boilers operate in the priority of DHW. That is, until open valves with hot water, the whole boiler was spent on the hot water and heating system at home do not get heat. To ensure reliable operation of most modern boilers are equipped with built-in "group security "that includes a pressure gauge, automatic air, a safety valve and expansion tank membrane (compensates for the increase in fluid when heated.) We should also consider electronic ignition with flame control, protection from a lack of gas pressure and the water from the formation of scale, freezing, and automatic diagnosis of the state apparatus. All of these necessary functions to help prevent occurrence of accidents and dangerous situations. According to specialists ARISTON (manufacturer of heating and water heating equipment), to reduce heating costs and keep the house comfortable temperature is extremely useful function such as a smooth change in heat capacity.
