How heat pumps work

Posted on 5 February 2014

A heat pump is a device whose purpose is to transfer energy gathered from an energy source to a destination called a heat sink.

Air conditioners and freezers are examples of heat pumps that we are more familiar with, however the term itself tends to be generally applied to many HVAC devices used for heating or cooling.


Solar energy in a nutshell

Posted on 30 October 2013

The Sun is the Earth's most cost effective power source. The amount of energy received from the Sun in only one hour is more than the whole population of the world could use in one year. Yet solar power amounts currently only 0.04% of the world’s energy.

Is your home climate friendly? Would you like to find out what you can do in order to reduce your carbon footprint? Here are some simple tips that are worth considering if you take the environment seriously.


Air Source Heat Pumps Explained

Posted on 28 February 2013

An air source heat pump is usually placed outside at the side or back of a property, and absorbs heat from the air and boosts it to a higher temperature using a heat pump. This heat is then used to heat radiators, underfloor heating systems or even warm air convectors and hot water in your home.


Solar Panels Explained

Posted on 26 January 2013

The most common type of solar panels - the ones you normally see on people's roofs - are called photovoltaic (PV) panels (photo = light, voltaic = to do with electricity). In other words, PV panels convert sunlight directly into electricity.

Kind Energy

Posted on 14 September 2012

If you are looking for ways to reduce your carbon footprint as well as your energy bills, solar panels are your solution. Solar energy comes from using the sun as fuel to generate energy. In fact, just the tiny fraction of the sun's energy that reaches the Earth is enough to meet all our power needs many times over. Solar panels are be used to change this vast energy to some kind of productive energy, available in the form of heat, to heat your home for example or electricity which can be used to power anything from your calculator to the whole business or household.


Solar water heating systems

Posted on 14 August 2012

The benefits of using a solar water heating system

Hot water from the sun and for free... what could be better than that? A solar-powered water heating system should cover all of your hot water usage in the summer. In the winter, you will have to rely on a secondary immersion heater system with the solar-powered water heating system still heating the water on very overcast days. Other befits include:

  • Hot water throughout the year: the system works all year round, though you'll need to heat the water further with a boiler or immersion heater during the winter months.
  • Cut your bills: sunlight is free, so once you've paid for the initial installation your hot water costs will be reduced.
  • Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
