Question

Look up “heat pump” on the Internet. What can you find out about the coefficient of performance (COP)? What is the cost? Would a heat pump be a good investment in Boston, Massachussetts? (Don’t guess. Work out some numbers.)

Answer 1

the efficiemcy of heat pump is denoted by coefficient of performance. The coefficient of performance is determined by the ratio between useful heat extracted from the condensor

The cost of installing a small heat pump at wall in a single room is about 200$ to 500$. And for higher end heat pump its becomes 4000$ to 5000$.

Of course it is a good investment in Boston, Massachussetts. They must use hyper heat system. They can give perfect comfot upto minus 13 degree.
