Tips to optimize efficiency of central heating systems

Energy savings in condominiums. Upon application of thermostatic valves combined with contacaloria will ensure reduced consumption of heating in old buildings (70% of the total) with centralized

A large part of the condos built in recent years have heating systems designed according to outdated rules and obsolete. These buildings have common systems of heating vertical risers, were built in a time when there was no talk of an energy crisis, are buildings whose heating and 'unbalanced: the occupants on the upper floors are cold, the lower floors and intermediates, open the windows.

The use of thermostatic valves combined heat cost solves this problem because if the lower floors and medium draw less heat there will be greater availability for the upper floors without spending to boost the boiler, in addition it encourages saving because the total expenditure the heating is distributed for 30% (fixed) on all and the rest in proportion to the calories taken from each. It applies the fair concept: "less consumption, less pay"

In advanced countries such as Germany, Austria, the Nordic countries are required to be 10 years, tried and tested and, according to techniques of high accuracy. Even in rich Switzerland, lavish Banks and public offices adopt this system. In Italy this system is slow to take root in ignorance. In short, the rich Swiss paying attention to savings, ordinary people instead tend to "do the Americans." The rich preserve and maintain the value of their property (retaining the high energy class), the other squandered by opening windows instead preferring to watch the gradual devaluation of their property that will end up in low class with depreciation of 30-40% compared to the values a few years ago.

Among other things, it is certain for a thousand and more 'reasons that the central heating system with heat metering is more' cost-effective than the plant alone. To prove the Piedmont Region authorizes new construction only when equipped with centralized system accounting.

The positioning of valves and metering systems is performed in a couple of hours without break or soil; The calorie count is sealed to prevent tampering, the display the occupier can monitor its daily consumption and verify afterwards the correct charge, the reading is done "radio" without the need for the meter reader to enter into the house. E 'statistically proven that stimulating the interest (less consumption, less pay), the saving of the expense of heating is around 20% -30%, and more' in the case of second homes; The reasoning is simple: "If I assento for shopping ruoterò the thermostat applied to the valve to low values. Same thing when I go on holiday at Christmas or if I'm away for the weekend, or if I'm away all day for work, but if the rest will take care in the home during the day to lower the temperature in the bedrooms, and vice versa during the night. Supplier firms are best German (Techem, Simens, etc..) Because, as mentioned, in Germany (and Austria) for a decade, there is an obligation to placement of this equipment and therefore supply companies have been run in the system and gained experience.

But we explore the various aspects of the problem in a complete way:

 

The accounting

The heat metering consists of a technological system, as mentioned widely used (in Switzerland, Germany, Austria, Weights Northern Europe) in apartment buildings with central heating system allows you to independently control the temperature in each housing unit and divide the costs in proportion as each consumes. In this way you get a saving on fuel consumption of between 20% and 30% per year. The operation is possible even in older buildings, with a total cost that is around thousand euro per housing unit and is proportional to the number of radiators. For the installation you need a simple majority resolution condominium that has jointly installation and adoption throughout the condo of the following products and services. Given that the quorum for the proper conduct of 'condominium meeting for this type of intervention amounts to 333.333 milliseconds, given the recent rules on the resolution is sufficient that the expenditure is approved by a simple majority of only thousandths (regardless of the " heads ") equal to 167 milliseconds. The decision not contested within 30 days, becomes enforceable

 

The temperature control

On all radiating bodies installing a thermostatic valve and rotatable graduated that allows adjustment of the ambient temperature. The valve cools the radiator where the environment has reached the programmed temperature and heats up again when needed. In the complex of the condominium this mechanism decreases the amount of water in circulation in the system, decreasing the activity of the boiler and determining the energy savings (in a similar manner to a cooking pot which is heated when it is first filled half).

 

The accounting

On all the heating elements installed a heat meter electronic device for detecting the consumption of each radiator. The installation is very simple and intervention, even if it requires skilled technicians, it is fast and does not require masonry work or wiring. In systems of the latest generation contabilizzatori have within them a radio transmitter that allows you to read from the outside of the property.

 

The adjustment of the thermal power plant

To adjust the pressure variations caused by the opening and closing of the thermostatic valves and avoid consequent hiss and noise that occur in some cases, it is recommended that the installation of a central heat pump with variable pressure. Alternatively, for smaller installations, it is sufficient to install a pressure relief valve.

 

The breakdown of costs

At the end of the heating season, the condo fees are allocated among the real estate units in proportion to the reading of heat meters. A minor part of the expenditure at the discretion of the building (typically 30%) continues to be divided according to the thousandth general, to compensate for common costs and heat loss of the heating system.

 

Tax Deduction and financing

The expense can 'benefit from the tax deduction of 36% to boast the Form 730 or Act. The 'intelligent condominium administrator may agree with a Bank loan to low interest rates in favor of the less favored to be repaid in an amount equal to the estimated saving. If for example the expense of the elderly, stood at € 1,000 per annum and with the valves will be reduced to 700. means that the elderly will be able to effortlessly have 300 euro per year to repay a small bank loan negotiated at a favorable rate. Finished paying the small loan without shaking at their own pace of expenditure, will be supported constantly saving of 300 €. Also if you need to sell will find more 'easily buyers.
