Heat Pump Refrigerants

Heat pump refrigerants have steadily evolved since 1987, when the Montreal Protocol set the objective of phasing out harmful refrigerants for the environment. All heat pump and air conditioning refrigerants have their pros and cons. Due to urgent action needed now to avoid catastrophic climate change, natural and man-made refrigerants with low GWP are becoming essential. This BLOG discusses man-made and natural refrigerants. The latter are gaining widespread support because of their environmental and performance benefits, which outweigh concerns about flammability (apart from CO2) that can be managed.

Heating and Cooling Systems add Value to your Home

This BLOG discusses all-electric heating and cooling systems adding value to your home. It discusses mandatory energy ratings that have been in force in the UK and Europe for more than a decade, slowly catching on in Australia starting with the ACT. The justification for all-electric heating and cooling includes: a) lower running costs with solar power, b) adding value to your home and c) reducing Greenhouse emissions.
