Any user of mobile knows how much you pay for each second that speaks, but few know how much is spent per kilowatt-hour of light in the heating of your home (depending on the contracted rate, about 0.016 euros), despite the rises in the prices of natural gas and light in recent months. It is an example of the level of ignorance that exists on a basic service for the citizen. What is the best system, which provides the sufficient warmth for every home at the lowest price? Depends on the type of House (House or floor, new or old building), its size, use given (regular or sporadic) and the area because an ideal system for Sevilla is not valid for the Aragonese Pyrenees is located. These are the most popular systems:
Gas condensing boiler
It is the best option if available supply of natural gas, according to the Organization of consumers and users, which highlights its high heating performance, which emits little CO2 and is very efficient. Often the buyer of a home is already installed heating system, which often only requires a reset of the device. It offers hot water and heating with a common temperature stays, by means of a central thermostat and in each room by means of thermostatic radiator keys. It has expenses of installation and you need maintenance, but along with the electric radiators is the system that consumes less, from the economic point of view.
It is ideal for a flat of between 90-100 square meters in a temperate zone as Madrid, that is complementary with an air conditioning unit. It could also be the option in a dwelling of the same characteristics in a city like La Coruña. The major energy companies have tools on their websites to calculate the approximate cost depending on the housing.
Rate night with accumulators
It is a system that provides water and heating to each stay with power supply requires hiring a special electricity tariff called night tariff or the current time discrimination, providing a period of ten hours a day of more economical cost. The device (heat accumulator) is designed to maintain a stable temperature of the room throughout the day, but only consumes at night, when the price is cheaper. It is the ideal system for houses where there is need a stable temperature throughout the day, as in the case of older people just leaving home or homes with small children. Next to gas boilers are the most commonly used in large houses. The adaptation of the House has a surcharge above the electric issuers. It consumes a little more than gas boilers and emitters, but provides more comfort in homes with heavy usage throughout the day. Dynamic accumulators reach 1,000 euros and the static, 500 euros.
They are individual for each room, specially designed heating appliances as known systems of gas heating radiators. Most are digital and allow you to program your operation by stay at various times sections. Most recommended heating system for temperate areas with intermittent applications is and they can combine with accumulators of heat in medium flats (90-100 m2) in cities such as La Coruña and splits for air conditioning in small apartments or flats in warm areas such as Seville. It is the system cheaper and more adaptable to any home because it does not require works and from the environmental point of view would be the most effective among electrical appliances by the rational given.
They are electrical systems that provide hot and cold air. They are suitable for warm and coastal areas, or as a complement with other installations of heating and hot water. They can be installed in individual rooms of a House with 1 x 1 Split or ducted which heated the entire housing. Air conditioning Inverter class a, are those who offer the lowest energy consumption. There are offers from 500 to more than 2,000 euros, depending on the required installation and brands.
These modern electrical appliances offer hot water, heating and air conditioning. They are systems used in single-family homes instead of diesel oil boilers. It is the most expensive option now – only heat pumps cost from 3,000 euros – but offering more services and the most efficient when combined with solar energy systems, mandatory in new construction since 2008.
The contribution of solar energy reduces energy consumption by more than half because low thermal jump they have to make devices for heating the water.
Even the air conditioning and heating are provided by underfloor, i.e. by a circulation of water under the floor, which is a system that it makes not ugly housing design and it is very comfortable for the uniformity in temperature. The aerotermia team is responsible for heat or cool this circuit.
The aerotermia is the most widespread of new technologies, although not the only one. There are boilers of biomass, which feed on economic fossil fuels, intended primarily for single-family homes or developments, and systems of geothermal energy to exploit heat from the soil to produce heat, but both are still evolving. Aerotermia, geothermal energy and biomass, in combination with solar energy, are the future of heating and air conditioning systems.
