A condensing boiler has a higher efficiency but also costs more than a traditional boiler to meet the thermal needs (heating and production of domestic hot water). Let's try to understand if the greater investment is always convenient.If you look at the economic convenience taking into account the payback time net of the incentives (the so-called pay-back), the condensing boiler is considered an optimal technology for satisfying the thermal need in residential environments, that is when it is installed in buildings intended for residential use.

Saving water means giving humanity a future because water, the blue gold that will replace black gold in the scale of strategic resources, will soon be a problem. Because? Because neglecting the climatic aspects that are changing a bit everything, the world population will reach 9 billion by 2050 and 48 nations, according to scholars, will face water scarcity by 2025.
Increasing energy consumption will derive from the ever increasing automation of industrial and residential systems and devices. So say the forecasts of the experts revealing the problem of higher consumption. We think of the robotic lines of a factory or of the small appliances found in any home.
With the arrival of winter, you have to deal with domestic heating! In fact, soon it will be necessary to turn on radiators and stoves, operations that affect one's home economy. To save on home heating, you need to pay attention to some important aspects that we will list below in the article.
If we look at the economic convenience over the entire useful life (i.e. on the basis of the average cost of the kWh saved or produced), almost all solutions and technologies for energy efficiency (except for glass closures and opaque surfaces) appear to be economically sustainable in all areas of application even in the absence of incentives.
A good dehumidifier is the appliance that, using electricity, is able to reduce the level of humidity in the air. An optimal environment should contain humidity values in the percentage range from 30 to 40. An air that is too dry leads to dehydration while an air that is too saturated with humidity leads to the formation of mold.
What is the carbon footprint of tagliatelle? The question was asked by the Luciana Mosconi pasta factory, a manufacturer of dry egg pasta in Matelica, in the heart of the Marche region. The company wanted the polluting emissions generated by the production process of its noodles to be compensated in some way by an environmentally useful action of equal weight.
Citizens are advised that the questionnaire of the carbon footprint project is online… what is online? I think I see the citizens of Bastia Umbra who mess with entering the data of their business, house and building with attached garage to allow the Municipality to calculate the carbon footprint of the country.
From an evolutionary point of view, the production of heat was the invention that allowed man to populate all areas of the Earth: starting from the first fires lit in caves to the most recent geothermal plants, the production of heat is also the process that requires the greatest energy expenditure and therefore the greatest pollution.
An award to the inventor of the self-service digital newsstand Meganews Magazines because "by aiming for innovation, the Meganews company has managed to change the traditional distribution logics of the publishing market". The motivation for the Cordial Business Awards also states that "Thanks to the availability of a wide range of magazines and newspapers and the print on demand model, Meganews has created an innovative, personalized and eco-sustainable service".
The Politecnico di Milano in its Energy Efficiency Report compared the economic convenience of the different solutions for energy efficiency taking into account in particular the Pay-Back Time, but net of incentives. The result shows that the best solution varies according to the application field, residential, industrial or tertiary, and that in general there is an optimal mix of technologies for energy efficiency.
The heat reflective panels are positioned behind the radiators and are characterized by a slender structure in expanded polyethylene, an insulating, heat-resistant, fire-retardant and non-toxic material. The expanded polyethylene is covered with an aluminum sheet which, thanks to its silver surface, is able to "heat reflect" the heat produced by the calorific, avoiding dispersions.
One of the first types of LED lamp The choice of lighting bodies must take into account two aspects: energy saving and quality of the light supplied. Both are important because if it is true that by installing efficient lighting fixtures you can reduce the energy bill, it is equally true that the quality of lighting affects living comfort (if we are talking about homes) and people's productivity (if we are talking about offices. ).
Organic Rankine Cycle SchemeORC is the acronym of Organic Rankine Cycle which refers to an organic Rankine cycle system that allows the recovery of waste heat output from industrial processes - but also from solar panels and geothermal plants - to produce electrical energy destined for different uses such as lighting, machinery operation etc.
There are many people intrigued by dry cleaning of the car. With the dry cleaning of the car it is possible to obtain several advantages both from an environmental point of view and from a quality point of view: the result of dry cleaning seems to be better than that obtained from the classic car wash with water.
OLED stands for Organic Light Emitting Diode (organic light emitting diode) and indicates a technology that will mark the future of lighting for many operators in the lighting industry. The problem is that OLED lighting technology is not yet available on the market, especially due to the high cost of the devices tested so far.
The operation of home automation is based on very specific characteristics such as ease of use, reliability, energy saving and automation. When it comes to automation, the operation of home automation is such as to allow the total management of electronic devices. electronic systems, security systems, communication and environmental management systems such as air conditioning (temperature, speed and humidity regulation), water heating (thanks to timers and thermostats), automatic lighting (thanks to sensors of movement that perceive the opening of a door or the entry of a person into the room), irrigation of the garden and remote fertilization, management of the pool ... In the specific case of automation, the operation of the domatica is based on a system of " sensors ”and“ actuators ”.
To save on heating there are many strategies to be implemented. In our guide article "how to save on heating" we have already seen six effective strategies for those who do not want to make major changes to their structure. Those who want to save on heating and are willing to make a few more investments, may find the following very useful.
The vacuum insulating panels can have a thermal conductivity varying between 0.004 and 0.008 W / mK, i.e. less than about 10 times that of the polyurethane and polystyrene panels.This feature makes them very interesting in the thermal insulation applications of buildings and in the industrial sector. because they allow a considerable reduction in thickness.
An intrados insulation of the attic is interesting for its ease of construction and the limited inconvenience of the intervention. Nothing to do with the insulation of the roof from the outside, which requires the preparation of scaffolding and the temporary removal of the mantle (with consequent unavailability of the rooms below).
How much does standby consumption weigh on the bill? Nobody can answer this question with certainty, yet the answer is crucial and weighs on consumers' pockets from bill to bill. Playstation and xbox, on or off, consume five times more than a refrigerator! The biggest mistake related to standby consumption lies in the collective imagination: if a person does not use an appliance, then save!
