"If the device has adjustable slats, orientate them towards the ceiling for cooling and heating to the ground. Clean the filter following the manufacturer's instructions. When leaving a unit, turn off the conditioner. Reversible heat pump It has the advantage of functioning as a source of heat source in winter and cool in summer. If you also need air conditioning heating, install such equipment as it will have two functions in one unit with half the consumption for heating. A variety of models and climate control systems.

It has a high performance, capable of providing several times their energy consumption. Its price is affordable for an economy medium (400 Euros per kW installed for appliances with power of less than 5 kW). You can control both temperature and operating time. Its size is small. The noise level is low. Installation is very simple.

Solar Hot Water System The hot water heating and hot water system can be up to 30% of energy expenditure of a household. The amount of water consumed varies depending on the uses and customs, but the biggest savings comes from a moderate use of this scarce resource efficiently. An efficient as the solar system can help you reduce your consumption and your bill. Solar thermal energy is economical because it may reduce your hot water bill by 80%, which amortize over time the cost.

It is also beneficial to the environment by reducing electricity consumption and hence emissions of greenhouse gases. When possible, perform the tasks that require hot water earlier in the day. This allows the water tank to heat up again by the action of the sun. In addition, we recommend setting the tank thermostat to 60 degrees. A minor adjustment, the less energy used to supplement the heating action of the sun.

Heating Systems Is summarized below in order of priority, the most profitable types to the tenant or homebuyer: The boiler (natural gas and fuel, propane, diesel) and water radiators. The most interesting systems are formed by water boiler and radiators, although within this group, differences in yields and prices according to type and size of the boiler to be used. This distinguished community facilities (boiler serves several households) and individual (each home has its boiler).

The community facilities have significant advantages over the individual: The performance of large boilers is greater than the small boiler wall and therefore energy consumption is lower. You can access more affordable rates for fuel (around 30% cheaper to neighboring communities with 10 or more dwellings). The collective cost of installation is less than the sum of the costs of individual facilities.

"The regulation and control systems (meters) allow for an unhindered services tailored to each house, so that each neighbor pay only what they consume. Individual facilities (output from 20 to 35 kW) have two types of boilers: Standard, with yields in the vicinity of 90% and condensation with yields in excess of 105%. These, although more expensive than standard (up to twice the price) can produce energy savings of over 25%, which makes it possible to recover the extra cost over a period of 5 to 8 years, when the life of boiler is over 15 years.
As in the previous group, there are community facilities and individual installations with the same advantages and disadvantages mentioned above. The hot-water radiators are replaced by a plastic tube, embedded in the soil wrought. Thus, the soil becomes heat emitter. The temperature at which water must be heated is much lower (generally 35 to 40 º C) wing radiator systems.
