Advantages of Heat Pumps Jacob Chandler
Why are they better than normal systems? Energy Efficient Environmentally Friendly Physical / Ascetics Economics
Energy Efficiency Coefficient of Performance (COP) ratio of btu heat output to btu electrical input conventional heaters have COP = 1.0 air source heat pumps: 2 4 water/ground source heat pumps: 3 5
Environmentally Friendly uses renewable heat sources ground/water use natural heat sources reduces energy used (electricity/fuels) geothermal best for greenhouse gases
Physical / Ascetics Heat pumps may have the advantages: no visible equipment no external fans quiet adaptable locations little risk of damage or weathering
Economics high capital cost low running costs heating and cooling in one device
