Clean air with pump?

It is inevitable to reduce the amount of energy used in buildings to improve the energy balance of Hungary and to reduce air pollution of towns (settlements). Heat pumps are world-wide known as a heating-cooling technology being most effective in energetic point of view, thus they compose a key element of energy efficiency and of CO2 emission reduction. Related to the technology of today - and of tomorrow - it is important to mention as well, that not only the heat source but also running of the heat pump and the input energy can originate from non-fossil sources. Potentialities of my country, namely its solar and soil heat energy reserves and its biomass energy potentials in a wide sense and its high level intellectual capital are favourable to the popularisation of heat pump technology utilising renewable energies. I am still in the renewable energy business, join me!
