What does a circulator pump do on a boiler?
The circulator pump contains an electric-powered impeller motor that removes the hot water from the tank to circulate through the pipes to the baseboard heaters or radiators. At the same time, the pump draws in cold water to start the heating cycle.Mar 28, 2014

This happens because the pump keeps the hot water moving throughout the plumbing system so that hot water is always available. In homes without a circulation pump, the hot water tap will run cool water until the hot water from the water heater eventually reaches the faucet.
What is the average life expectancy of a geothermal system?
Geothermal heat pump systems have an average 20+ year life expectancy for the heat pump itself and 25 to 50 years for the underground infrastruc- ture. Additionally, they move between three and five times the energy they consume between a building's interior space and the ground.
How much does it cost to replace a geothermal system?
Let's not sugarcoat it — installing a geothermal system is expensive. It costs $10,000 to $30,000 depending on your soil conditions, plot size, system configuration, site accessibility and the amount of digging and drilling required.
How much does it cost to replace a geothermal heat pump?
Average cost: $20,000 - $27,000 To install a geothermal heat pump in 2,500 square foot home will cost between $22,000 to $27,000. This is double the price of of a conventional HVAC system, but the savings on utility bills will be beneficial in the long run.
