Main Greenhouse Gases. Multiple gases contribute to the greenhouse effect that sets Earth's temperature over geologic time. Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived.

Heating a greenhouse – the challenge To keep a greenhouse frost-free, the temperature must remain above 32°F even in the corners. If the current of air does not reach there, then the temperature on the heater has to be really high, however, then a large proportion of the warmth goes up into the gable of the greenhouse, where it is not needed

Check all gas (or oil) connections, gas pressure, burner combustion, and heat exchanger. Improper burner operation can be caused by a dirty burner or a cracked heat exchanger—either can cause the equipment to operate less safely and efficiently. Leaking gas (or oil) connections are also a fire hazard and can contribute to health problems.

Read MoreCondensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

PROBLEM Replacements of residential gas furnaces with electric heat pumps can reduce overall carbon dioxide emissions associated with heating. However, the impact on CO2 emissions is dependent upon weather and the local carbon emissions of the electric grid. SOLUTION WCEC used whole-building energy simulation to predict the change in annual CO2 emissions resulting from replacement of
