Patients with mild aortic stenosis do not require treatment or restriction of activity. Patients with moderate aortic stenosis (valve area 1.5 to 1.0 square centimeters) are advised to avoid strenuous activities such as weight lifting or sprinting.hen symptoms of chest pain, syncope, or shortness of breath appear, the prognosis for patients with aortic stenosis without valve replacement surgery is poor.
A geothermal heat pump (GHP) is all electric, like your heat strips. Your heat strips make one unit of heat for one unit of electricity. A GHP actually pumps heat out of the Earth. So, for one unit of electricity, it will pump 3 to 5 units of heat into your home.
Hot water or steam from below ground can also be used to make electricity in a geothermal power plant. In California, there are 14 areas where we use geothermal energy to make electricity. The red areas on the map show where there are known geothermal areas. Some are not used yet because the resource is too small, too isolated or the water temperatures are not hot enough to make electricity.
