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.
Note. 1  A fracture not indicated as displaced or nondisplaced should be coded to displaced. 2  A fracture not indicated as open or closed should be coded to closed. 3  The open fracture designations are based on the Gustilo open fracture classification.
