Nos han utilizado para prender gadgets – como girar un dial o pulsar un botón – cada vez que queremos hacer nosotros mismos caliente. De hecho la tecnología ha sido parte de nuestro estilo de vida y las formas de generación de calor cada vez más nos ha proporcionado una mayor comodidad en nuestros hogares, escuelas o empresas. Lamentablemente, en un momento en que las preocupaciones ambientales han crecido graves y nuestra necesidad de recursos renovables se ha convertido en urgentes, no todas las tecnologías de calefacción funcionan con rentable y materiales ecológicos. Es en este contexto que la energía solar se convierte en un recurso ideal para la generación de calor.

La energía solar es fácil de generar, rentable y renovable. Todo lo que necesitamos es una fuente de energía solar – algo que atrae a los rayos del sol en ella y atrapa el calor generado por el proceso. Que, básicamente, es cómo funciona un solárium.

Habitaciones soleadas son construidos cerca de las casas o edificios. Ellos hacen uso de paneles de cristal construido a lo largo de las paredes, del suelo al techo, y por lo general hacia el oriente a derecha maximizar la absorción de calor en el momento en que el sol aparece. Los paneles de tomar en el calor emitido por el sol, la almacena y evita que se disipe. A través de los respiraderos y otros dispositivos, a continuación, almacena el calor se distribuye a donde y cuando es necesario, como salas de estar o dormitorios durante la noche.

En términos más específicos, las tecnologías que nos pueden ayudar toque solar de energía para calefacción, incluso durante el invierno incluyen lo siguiente:

1) una masa térmica absorbe y almacena la energía solar durante el día y distribuye el calor en la noche.

2) La Trombe Wall aplica las tecnologías de calefacción y ventilación. Combina el solarium y la masa de procesos térmicos en los canales de aire absorben el calor entre los paneles de vidrio y una masa térmica. El calor de la pared de las tiendas del sol, que finalmente se distribuye por toda la pared a través de rejillas de ventilación. La pared se convierte en la fuente de calor.

3) Como con paneles de vidrio y las paredes térmicas, un coleccionista de obras ocurrido con paredes que absorben la energía solar y calentar el aire en que ésta entra y se distribuye a través de la ventilación sistema.

Además, es reconfortante saber que la energía solar generada no sólo nos hacen caliente. Se ventila los edificios también. Un ejemplo es lo que llamamos Refrigeración solar. El proceso absorbe el calor solar que alimenta un motor de vapor que a su vez ejecuta los dispositivos de refrigeración. Otro ejemplo es el llamado Solar Chimenea. Dentro de la chimenea de la masa térmica es un hueco que calienta el aire se calienta y cuase a evaporarse. El proceso resulta en ciculation de aire y ventilación en el edificio.

Hay muchas maneras por las que puede calentar o enfriar nuestras casas, edificios o negocios. A diferencia de otros sistemas de calefacción que funciona a través de medios artificiales, el calor, las tecnologías que discutieron brevemente sobre la naturaleza del arnés – el calor del sol – como fuente de poder. Ellos son rentables, garantizando una excelente relación calidad-para las inversiones de dinero. Asimismo, no representan una amenaza para el medio ambiente. Responden a la necesidad de formas de guardar el calor cuando el sol está de tal manera que nuestra casa va a permanecer caliente durante la noche. De hecho, no sólo trabajo para la calefacción, que también trabajan para el enfriamiento.

Heat pumps are the technological wonders that are useful in a variety of purposes. A free supply of hot water with renewable sources of energy for domestic water uses and house warming purposes can be served by heat pumps. These equipments are useful especially when dealing with low temperature heat distribution systems used basically for under floor heating. Heat pumps follow a low cost and pocket friendly system of extracting hot water from underground or water resources. The principle attached with the working of heat pumps is pumping heat from a low temperature source and releasing it at a high temperature into the central heating system of all edifices.



Primarily, heat pumps are capable of providing both heating and cooling solutions for the comfort at homes. The quality of an effective heat pump is measured through the system by which it maintains the warmth of a dwelling and circulates air temperature amid hot & cold climatic fluctuations. Proper care must be taken before choosing the appropriate heat pump for the required purpose depending upon its features like power supply, total horse power supply it can generate, hours in a day it can constantly function and so on. Another important factor for deciding the correct selection of the heat pumps for a family is the climatic features of the place of residence.

The cooling efficiency of heat pumps is calculated according to Seasonal Energy Efficiency ratio (SEER) that is an average of the cooling output against the power input. On the other hand, the heating factor of these heat pumps is measured by the heating season performance factor (HSPF), a ratio of seasonal heating output and seasonal power. There are three types of heat pumps available in the market. Some that take heat from ground, from water resources like wells and rivers and directly from the air. Besides the ground source heat pumps are offered divided in two varieties – vertical loops ad horizontal loops.

Heat pumps are efficient as well as economical pieces of technology to provide you with luxurious and comfortable living. These equipments run on electricity and hence nature friendly. Heat pumps are durable and come with specified period of guarantees for long term.

In the last few years it became impossible to get away from the hype about green technologies versus fossil fuel technologies. Solar panels, solar thermal and wind turbines have ruled the headlines with major projects undertaken around the world. However, let us not forget the humble wood burning stove. Although not as flashy as a gleaming white wind turbine rotating at a steady speed over a green hill or a high-tech solar photovoltaic cell generating electricity out of simple sun light, the wood burning stove has some important benefits to bring to the table.

First let’s understand how it works. Biomass means that the energy is produced from organic sources (bio-energy). The energy is released when organic sources (wood in this case) are burned, in the same way as mankind was doing for centuries. The fuel used in biomass boilers is either untreated wood or treated wood. Most common fuels are logs, wood chips and wood pallets.

Wood pallets are the most efficient of the wood fuel types. They are made from sawdust which is compressed at high pressure into small pallets (roughly the size of AAA batteries). They are made from by-products of local carpentries, joinery workshops and sawmills. The high pressure compression removes moisture and increases their output to weight ratio, meaning you need less fuel to get the same amount of heat. Another benefit is that they don’t leave as much residue on the burner due to full burning reaction.

Fossil fuels are normally associated with global warming and climate change. When fossil fuels are burned (e.g. natural gas in your domestic boiler), they release CO2 as part of their natural chemical reaction. This gas was captured within the fuel for millions of years in underground deposits. By burning it now, we release this gas into the atmosphere. Biomass boilers are considered to be carbon neutral heating technologies, because they only release CO2 that was captured by the plant during its growth years, thus not bringing new CO2 into the global equation.

Here are some pointers on what to check before installing a biomass boiler:

* Local supply of wood – do you have a local sawmill or joinery workshop that can provide a steady supply of wood chips, or even wood pallets.

* Space and location – biomass boilers have larger footprint than a typical boiler and require further space to store the wood. It is essential to calculate the amount of space that would be available for wood storage next to the boiler

* Chimney – biomass boilers require chimneys. And more specifically, chimneys that are lined for wood burning. However, it is a problem that can be solved by adding a lined flue within the chimney.

* Smoke limitations – if your house is located in a ‘Smoke-Free’ zone you may have to look for a specially labeled product which is ‘exempted’ under the Clean Air Act.

* Other considerations – It is wise to check with your local authority’s planning department regarding fitting a flue in the property. This is very important in cases where the property is a listed building, or within a conservation area.

With the progress in technology, swimming pool heat pumps have become more efficient nowadays, than they were few years ago. If you have your own swimming pool, you must use pool heat pumps to heat it. Heating your swimming pool with pool heat pumps is an efficient technique of keeping your swimming pool comfortable in the entire swimming season.

Swimming pool heat pumps are usually the most effective method for heating swimming pools in warmer countries. They transfer heat from air to pool water quite successfully. When compared to gas, oil or electric heaters, pool heat pumps may cost much less, which can also save you a lot of money in energy costs. You may come across pool heat pumps that have dual temperature controls which will further enable you to heat your swimming pool at various temperatures.

What Swimming Pool Heat Pump Does

Swimming pool heat pumps usually heat your swimming pool to a desired temperature at a reasonable cost. You just have to set the device to a temperature you want; that is all you have to do. These heat pumps function great when the weather condition is not very cold. Pool heat pumps make use of the outside air as free energy source. Even if the outside weather condition is not great, swimming pool heat pumps will keep your pool in the desired temperature for a perfect swim.

Swimming pool heat pumps keep your pool heated at constant temperature; this type of pump heaters is an absolute requisite for someone who is a good swimmer. They are great for heating pools efficiently and quickly when time is a factor.

A pool heat pump functions in the similar principle as a refrigerator or an air conditioner, but in reverse. One of such units usually consists of heat exchanger, ventilator, condenser and compressor which also include a refrigerant.

How Swimming Pool Heat Pump Works

Pool heat pumps use electricity to operate their pumps; however, they may also use the sun-warmed air at times. A fan stirs the warm air through evaporator coil which collects heat from the atmosphere. The coil contains liquid refrigerant that absorbs the temperature from the air. After this process takes place, it changes into gas. The gas then is pushed into a compressor that further intensifies the heat.

After the gas becomes too hot, it shifts from compressor to heat exchanger condenser. It is here where water passes through, and cool swimming pool water is pushed through heat exchanger condenser. As it passes, cool water takes up the warmth from the gas. As a result, the water turns warm while the gas turns cool. If you have to maintain a daily, continual swimming routine, swimming pool heat pumps are just perfect for you.

Ground Source Heat Pumps

The primary difference between a ground source heat pump and a conventional boiler is that a conventional boiler is usually designed to heat the property between certain hours. It achieves this by outputting an enormous amount of heat over a short space in time. The property heats up, the boiler switches off and the house goes cold again.

A ground source heat pump works differently to this. The ground source heat pump does not like producing very hot water. A conventional boiler might output water to your radiators at a temperature in excess of 70 degrees C. A heat pump can achieve this but it would be inefficient in doing so.

Therefore the style of heating needs to be changed to accommodate lower temperature heat output.

In general this means using underfloor heating (running at a low temperature, perhaps 38 degrees C) or radiators that are oversized so that they can run at a lower temperature than normal (perhaps 50-55 degrees C).

When the output temperature of the system is lowered it is vital that this heat is retained as the time taken to heat the whole building will increase.

The key to a good ground source heat pump installation is insulation. Great insulation will benefit any home, whatever the type of heat system. However, for a ground source heating system to operate without a back up it is vital.  This will provide the property owner with a very efficient and cost effective heating system.

Air Source Heat Pumps

Air source heat pumps work in a similar way to ground source heat pumps but extract heat from the air outside rather than the ground. They upgrade this heat using a compressor circuit (similar to that found in a fridge).

Typically over a year an air source heat pump could have an efficiency of around 330% when heating a domestic home (including domestic hot water). This means that for every unit of electricity that it uses it generates 3.3 units of heat.

A modern high efficiency gas boiler has an efficiency of around 90%. This massive efficiency advantage means that the system will save you money off your fuel bills.

Comparing the system to a gas boiler you should save around 30%. Given the cost of oil, when replacing an oil boiler the savings can be up to 60%.

This type of heat pump can also be used for heating swimming pools.

Ground Source Heat Pump vs Air Source Heat Pump, which is right for me?

The difference between these systems is that Air Source Heat pumps do not need a ground loop , they extract heat from the air around us. The disadvantage with an air heat pump is that as the ambient temperature outside decreases, the air heat pump becomes less efficient at extracting the heat.

One other fact of central heating systems is that you need them most when the outside temperature is at it’s lowest. This means that air heat pumps are useful for heating properties that don’t have the room or funds for a ground loop or need heat when the ambient temperature is generally higher. This means that air heat pumps along with unglazed solar water panels are very useful for heating swimming pool water.

In summary, if you want to heat your home efficiently with electricity, consider a heat pump. If you have a ground source heat pump you will benefit from good efficiency all year round.

Given that the major consideration between these two technologies is the annual efficiency, it is worth knowing that a ground source system could have an efficiency of around 450% when an air source system would be about 350%.
