![]() How much of my annual heating and cooling needs can a heat pump provide?.What types of heat pumps are available?.If you are considering a heat pump, you likely have a number of questions, including: Given the wealth of different system types and options, it can often be difficult to determine if a heat pump is the right option for your home. They are also an option when replacing existing air conditioning systems, as the incremental cost to move from a cooling-only system to a heat pump is often quite low. Heat pumps can be an excellent choice in a variety of applications, and for both new homes and retrofits of existing heating and cooling systems. Heat pumps are a proven and reliable technology in Canada, capable of providing year-round comfort control for your home by supplying heat in the winter, cooling in the summer, and in some cases, heating hot water for your home. If you are exploring options to heat and cool your home or reduce your energy bills, you might want to consider a heat pump system.

One of the earliest wireless telephones was based on radiant energy. It can be generated electrically by infrared lamps, or can be absorbed from sunlight and used to heat water. Radiant energy, as well as convective and conductive energy, is used for heating homes. Radiant energy produced in the sun is a result of nuclear fusion. In geophysics, transparent greenhouse gases trap the sun's radiant energy (at certain wavelengths), allowing it to penetrate deep into the atmosphere or all the way to the Earth's surface, where they are re-emitted as longer wavelength radiation (chiefly infrared radiation). Such an open system can be man-made (such as a solar energy collector), or natural. ![]() Radiant energy is one of the energy sources that can be used to power an open system. Radiant energy may originate in a body or be reflected from another body (in which case it may be refracted or otherwise modified). Such radiation bands may be sharply defined, as is seen in star spectra, or may be more diffuse.ĮM radiation has three principal components: wavelength and frequency, which are strictly inversely proportional, and intensity, which determines the amount of energy carried by the radiation. The radiation emitted by radiating bodies is concentrated in certain portions of the electromagnetic spectrum. Because elctromagnetic (EM) radiation can be considered as consisting of photons, radiant energy can be viewed as the energy carried by these photons. ![]()
