Heating breakdown repairs

Availability of fossil oils and gas is time limited and there are more and more Heating repairs Kingston. This fact is more on mind of people just as well as the need to protect environment. This is the reason why usage of renewable sources of energy is becoming more and more important. Unlike other sources of renewable energy such as solar energy and wind energy, heat from surroundings (earth, water, air) is available around the clock, all year round. Heat pump without additional energy source can cover all household needs for heating and hot water. Heat pumps are devices that enable transfer of heat energy from a lower-temperature level (earth, water, air) into a higher-temperature level (central heating or hot water) using additional energy for work (electricity for compressor) in an appropriate work medium circle process. They are very efficient and there is minimum need for Heating repairs Kingston.Work principle of heat pump is simple and can be compared with the fridge, only in a reverse function: it heats instead of cooling.
Energy from the surroundings goes in a work matter to compressor that pressures work matter which increases its temperature that is then through condenser and exchanger within condenser receiving heat and sends hot water for heating in a central heating system. After depositing hot water into a system, work medium goes to evaporator over expansion valve. In expansion valve, working medium expands from higher condensing pressure on lower evaporating pressure and cools off. This closes circle process evaporation-condensation-expansion that repeats all the time.
Working medium in compressor circle is Freon (R407C, R404A, etc.). Heat pumps that use electricity get approximately 3/4 heating energy from surroundings and the remaining 1/4 is electricity necessary to start compressor. From the ratio of delivered heat energy and used electrical energy you will get efficiency coefficient that describes efficiency of heat pump (3+1=4). For the standardization purposes, there is unique COP coefficient of performance that describes ration of heat change comparing to invested work. Simply put, if heat pump has COP 4, it provides 4 kW for every 1 kW of spent energy.
