Even in states with no good geothermal resources, a geothermal heat pump can still give space heating and air conditioning. Like a refrigerator or air conditioner, these systems use a heat pump to force the transfer of heat from the ground to the application. In theory, heat can be extracted from any source, no matter how cold, but a warmer source permits higher efficiency. A ground-supply heat pump utilizes the shallow ground (commonly at 10-12°C, 50-54°F) as a source of heat, hence taking benefit of its seasonally moderate temperatures. In contrast, an air-source heat pump draws heat from the colder outdoors air and thus demands far more power.
That was the extended answer to your query. The quick answer is $2000 to $4000 and up, depending upon the quantity of prep, the quantity of coats, the quantity of trim, and the paint used. The aim is for five,000 MW of that figure to come from geothermal power, which would make it the country’s key power source in a move that could aid reduce fees to customers. We make it economical to install a geothermal heat pump system with rebates of $500 to $1,500 provided by the Connecticut Energy Efficiency Fund for qualifying systems.
Not substantially has changed considering that that date below CEO Tom Huntington who took more than from the dynamic former CEO Bruce Ritchey. Maybe the only glimmer of a new path is international sales expansion beyond the USA and Canada, exactly where the tiny sales volume tripled in spite of getting no focus by management. Thats about 4.34kw per sq ft per year. Passive standard would be 4746btu/sq ft per year. That is 1.39kw. Insanely low and achievable only with enormous amounts of insulation. My home (1940′s) has been completely re-modeled. Which means all walls, floors removed, built and re-insulated.
Electric bills are large. Though when you total what I use to pay for oil to what I consume in electric bills I come out around $500. and that is possibly greater now due to the fact the cost of oil is constantly increasing. But so is the cost of electric. Water drawn off from geothermal sources tends to have other substances dissolved in it. A single component of geothermal energy cost is in dealing with these.
