New gas swimming pool heaters have a standard test they go through to determine their energy efficiency based on their Btu (British thermal unit) output. Heater efficiency is the ratio of usable output to energy input. For example, an 80%-efficient heater uses $80 worth of useful heat for every $100 worth of fuel.Therefore, it wastes 20% of the fuel. Most gas pool heaters feature their efficiency percentage on their nameplates. A pool heater's manufacturer can also provide its efficiency percentage.Today, you'll find some gas pool heaters with 89%â95% efficiency. The following table shows how much you can save for every $1,000 in annual pool heating costs by installing a gas pool heater that's 95% efficient.or example, an 80%-efficient heater uses $80 worth of useful heat for every $100 worth of fuel. Therefore, it wastes 20% of the fuel. Most gas pool heaters feature their efficiency percentage on their nameplates. A pool heater's manufacturer can also provide its efficiency percentage.
Expect surgical treatment. The standard medical treatment of an open fracture is surgery. From cleaning the wound in the operating room to stabilizing the bone and closing the area, the goal is to reduce infection, improve the potential for healing, and promote the functional restoration of the bone and surround joints.
Repositioning bone without surgery is closed reduction.. Most fractures in children are treated with closed reduction. Serious fractures may require open reduction -- repositioning using surgery. In some cases, devices such as pins, plates, screws, rods, or glue are used to hold the fracture in place. Open fractures must also be cleaned thoroughly to avoid infection.
