General Heat Pump Questions

Heat Pumps deliver hot water day and night. They produce hot water 24/7

You have tried to find out as much as possible about solar heating. So how much does a solar system save you and how would this compare to a heat pump?

 Heat Pump Comparrison - year

They compared a low end medium quality Solar Water Heater (SWH) and a high quality SWH with a Heat Pump and found the following savings for each system as :-

As you can see the Heat Pump out performed the SWH systems with a greater saving in electricity. 
Why? A Solar heating system only saves on your heating in the middle of summer on a nice hot summer’s day. On an overcast day or in the evening, however, there are no savings and the conventional back-up electric heating element heats the water.

Heat Pumps also save more than other kinds of water heating.
