Sharing systems, underfloor heating and heat pumps can significantly reduce the energy consumption for space heating. In this case, the savings are achieved both at the stage of energy production, and at heat transfer. The energy source for the heat pump can be soil, rock, lake, air (for specific models), in general, any heat source with a temperature of – 1 C and above, available in winter. This may be a river, sea, the wastewater outlet of warm air from the ventilation system or cooling system of an industrial equipment. External circuit, collecting the heat of the environment, is a plastic pipe, laid in the ground or water. Material pipe – HDPE.
Pipeline diameter – 40 mm. Coolant – 30% ethylene glycol solution (or ethanol). The required length of pipe, laid in the ground or dropped into the hole, calculated by a special program Thermia The main difference between the heat pump from the other generators of heat energy, such as electric, gas and diesel generators, the heat is that heat production Up to 80% of the energy is extracted from the environment. Thus, it can get 3-4 times more heat energy than the electrical energy consumed. In addition, choosing a heat pump, you choose comfort. Appears opportunity to cancel or substantially reduce the use of diesel generator, which means less time on maintenance. And, of course, it saves energy and money.
Today in Russia the cost of heat production greatly depends on the type of "fuel": the cheapest is natural gas, then electricity and diesel fuel. However, this is only the present situation, the price of energy all the time changes. Due to its specific characteristics and heat pumps are especially effective combined with water heated floors. With this combination of energy not only "made" economically, but also economical in use! The temperature in the heating system supplied from the heat pump does not exceed 55 C, and the return water temperature must not exceed 50 C. The ratio of consumed electricity generated to heat the heat pump largely depends on the heating system, which supplies heat to the heat pump: the smaller the estimated temperature of the coolant, the greater the efficiency of the heat pump. Radiant Floor – low temperature system heating medium temperature is typically 30-45 C. When the radiator heating system must be specially calculated heaters that use heat pumps. When installing underfloor heating No special calculations of the efficiency of the heat pump is not required, these systems are made for each other! Even with the correct calculation of the radiator heating system using heating system "warm sex "will always provide a more efficient use of energy accumulated in the environment! By the way, the heat pump produces heat, not only during the heating season, warm to hot water systems produced all year round. But for the average country house cost to prepare the hot water is about 15-20%.
