It depends on how much your heat pump is used, checked, serviced, and how well it is maintained. (Always have your HVAC systems regularly maintained to increase life expectancy!) The usage of a heat pump varies greatly depending on where you live. Other factors can include if it is an air-source or ground-source. So, a very general ball park life expectancy of a heat pump is anywhere from 15-25 years for the inside components.
If the pump is not circulating coolant insure that the thermostat is not stuck closed. If the thermostat is ok then the pump will have to be replaced.
My guess would be between 100K and 150K on average.
By measuring outlet temperature of water at downstream of pump and upstream of boiler.
What was life expectancy in
According to the World Health Organization, both Costa Rica and Chile are the most advanced countries in this regard, with a life expectancy of 79 years (2011):Chile: Male life expectancy: 76Female life expectancy: 82Overall life expectancy: 79Costa Rica: Male life expectancy: 77Female life expectancy: 81Overall life expectancy: 79
It should last at least 100,000 miles or more but there is no guarantee.
There is no set life expectancy. Could be 25,000 miles or 200,000 miles.
Antiguas life expectancy is 90
The 6m head pump can lift 6 meters. The 5m head pump can lift 5m. Note this has no impact on the volume of liquid that is pumped.
the life expectancy in Greece is80.4 years
The life expectancy is 73 years.
