Necessary amount of energy in a house or a building depends on the object design, orientation, construction and level of heat isolation on the outside layer of object, as well as climate conditions. This will also affect the need for Heating repairs South Bank. Information that can be used to calculate how much heating you will need for your home depends on climate, and it is usually calculated as multiplication of number of heating days and difference between average inside and outside temperature. Another important information you will need to calculate amount of heating energy is coefficient of passing of heating through outside construction part of the house. This coefficient is marked with U or c. As in literature both of these marks appear, it is not uncommon to see it marked as U(c). Heat losses through construction material depend on the construction elements, orientation and coefficient of heat conductivity of built in materials.
Coefficient of of heat transfer U is amount of heat that construction element losses in a second per square meter of surface with temperature difference of 1K, expressed in W/m2K. Coefficient U(k) is important characteristic of outside element of construction and has important role in analysis of heat losses, and with this also in energy expenditure for the heating. The lower heat transfer coefficient, the better heating isolation of the building.
Overall energy balance of the house includes: transmission heat losses and heat losses due to ventilation, usable interior heat gains, usable heat gains from the sun, heat losses from a heating system and energy brought into heating system.
Annual necessary heating energy for heating needs of the home, Qh (kWh/annually), is calculated amount of heat that heating system needs to bring the heat in a building to maintain projected temperature within the building.
Such expression of energy expenditure in buildings per square meters gives us unique data that enables energy qualification of buildings and comparison of different energy characteristics of buildings. This will also enable you to get an idea of realistic need for Heating repairs South Bank.
