building heating systems

Man has for millennia accumulated heat to improve comfort, increase comfort and save fuel. Accumulation means storing, saving energy from one period to another.
Almost all boilers, both wood, wood chip and pellet boilers installed have too much power in relation to housing needs. With a water-filled heat accumulator heat heart of the system, many problems can be avoided while all forms of energy used for charging. It is then the accumulator size in relation to the housing needs that determines how often charging must be done. A house heating system is not really completely finished without an accumulator tank.

When burning wood customized storage tank size so that with one or two per day fuel heating keeps the house warm even. You can then burn with steady and high effect on the time of day when you have time to burn. Thereby contributing to the storage tank to improve both comfort, environment and fuel consumption. At the chip and pellet heating tank used more as effektutjämnare and volume can therefore often limited to 500-1000 liters. In order to do a proper dimensioning, particularly in wood burning, one must take into account the building's power demand, firing the wishes of firing ranges and boiler capacity.

Depending on which end you start to get some different calculations. For example if you have an existing boiler which for some reason want to add a storage tank should begin by starting the boiler performance. This may mean that customers sometimes depart the comfort of boiler capacity is not quite enough, or that the volume of the tank will be greater than expected. An important rule of thumb that always applies is that you should never have a smaller accumulator than a fully loaded wood boiler produces energy since the startup of the boiler heat storage deducted. Another rule of thumb - according Swan requirements - is that the accumulator should never be less than 18 times vedeldstadens volume.

For more compute the output requirement at a certain outdoor temperature is easiest if you know the energy needs of over one year, for example, via a utility bill or oil consumption, etc. This is a good aid when this task includes the property's actual consumption that includes both housing needs as well as the family's hot water habits , ventilation and the like. Important to remember when doing these calculations is that there is a net energy can be calculated. It means that you also have to take into account the existing plant efficiency in case it started from a known consumption. An old and poor oil boiler can indicate an excessive power demand if you just take into account oil consumption.

If one assumes that a villa with an oil furnace that is 20 - 25 years can be expected that the system effectively garden is rarely better than 65 - 70%. One cubic meter of oil contains about 10 000 kWh. This means that oil consumption of 3.5 m3, representing a net energy of 35 000 kWh x 0.70 = 24,500 kWh / year. On an electricity consumption, it is common that even household electricity included. For a normal family usually calculate household electricity between 5-6000 kWh / year. This must therefore be subtracted from the total. If you make the 25 000 kWh, the net demand for heating hot water 25 000 kWh - 5000 kWh = 20,000 kWh / year. This applies if you have direct electric heating. If you have a water boiler and radiators can instead assume that the system efficiency over the year is around 95%, resulting in a net requirement of 20,000 kWh x 0.95 = 18 000 kWh / år.Människan has for millennia accumulated heat to improve comfort, increase comfort and save fuel.
