The 31% eco-bonus for interventions aimed at energy saving has been extended until 2014 December 65 and 50% deductions for renovations and the purchase of furniture and appliances
In times of economic hardship may seem excessive spending, but the replacement of the old boiler can be, right now, a strategic and forward-looking to reduce consumption on heating.
Most units with heating, over 10 years, has served as a boiler room open or sealed gas or LPG traditional. The boiler, after ten years of age starts to consume too much, pollute more and requires greater expenditures of money in case of failures, both for the procurement of spare accessories that for labor.
To consider also that the old “open chamber” boilers are much more dangerous for users as bad combustion can introduce carbon monoxide directly into the premises, a gas that is extremely dangerous for human life. How to recognize the type of boiler? First of all, it is good to keep the boiler booklet and the use and maintenance booklet where the characteristics of the boiler itself are specified or just "look" at the boiler to understand what type it is:
- if the boiler is of the type with flame reached, it means that we talk about open room, that is the flames that burn use the air of the room as comburent. Your boiler is open chamber. Precisely because it uses the oxygen present in the air of the room to give rise to combustion, it is necessary to have air intakes of adequate size (generally on the perimeter wall or in the windows). In case of malfunction it can be very dangerous as it is able to release carbon monoxide into the environment. It is therefore essential to carry out periodic checks.
- if the flame rather not be reached and the boiler start 2 pipes is probably a boiler room closed. In fact, one of the two pipes is the flue, the other with a smaller section is the pipe that captures the external air (comburent) in order to give rise to combustion. This type of boiler is safer because in the event of imperfect combustion it does not release toxic gas into the ambient air.
The power plants with less than 35KW (independent boilers) should be checked every four years, with the exception of open chamber boilers on living quarters or systems over 8 years of age which must be checked every two years. Each Region can establish restrictive regulations, for example in Lombardy the two-year obligation is extended to all plants under 35 KW regardless of age and type. Plants with power over 35KW must be overhauled every year.
The responsibility for the overhaul lies with the landlord and tenant of the house where the system is installed or on the Administrator for centralized systems. The tenant is therefore required to periodically check the boiler while the owner is required to ensure the safe use of the same through any extraordinary interventions such as replacement and substantial extraordinary maintenance interventions.
Maintenance consists in cleaning the system with compressed air, checks on operation and safety. Maintenance, at regular intervals by law, also provides for the control of fumes and consists in measuring the quantity of gases present in the combustion and their temperature, allowing both safety and atmospheric pollution to be checked. Maintenance can only be carried out by professionals registered with the chamber of commerce and in possession of the specific qualification as required by Ministerial Decree 37/2008.
Tax incentives allow today to recover the 65% of expenditure for the replacement of the generator (boiler) and installation of thermostatic valves in the case of radiators. But be careful, because it saves on fuel is a must because the rules require that the new boiler has yields minimum wage to ensure the containment of consumption. To obtain the advantages is compulsory to install a system with a yield of at least three or four same. The boiler efficiency is the ratio between the energy produced and the consumed energy (combustion efficiency) and is measured in percentage and number of stars. The traditional high-efficiency boilers have an efficiency of three stars (from the 92 98% on average), while the condensing returns have four stars (even more than 100%, only possible because you enter a parameter that is not in the traditional equipment you can recover and was not included in the calculation of the energy). The cost for a condensing boiler with power under the 35KW can vary from 2.500 5.000 to the euro.
To be eligible for deductions you must forward to ENEA, at the end of the work, the request by compiling with all the required data, the boiler efficiency, amount of the expense that must be paid by bank transfer special. It is also necessary to have opened a building practice in commonEven a simple communication to log in for routine maintenance works.
