On the surface, Home Depot and Lowe's seem remarkably alike: massive big-box stores where you can buy everything from screws to paint dropcloths to major appliances to everything you need to build ...
[1] [2] It therefore has units of BTU/watt-hr. The higher the HSPF rating of a unit, the more energy efficient it is. An electrical resistance heater, which is not considered efficient, has an HSPF of 3.41. [3] Depending on the system, an HSPF ≥ 9 can be considered high efficiency and worthy of a US Energy Tax Credit. [4]
For example, consider a 5000 BTU/h (1465-watt cooling capacity) air-conditioning unit, with a SEER of 10 BTU/(W·h), operating for a total of 1000 hours during an annual cooling season (e.g., 8 hours per day for 125 days). The annual total cooling output would be: 5000 BTU/h × 8 h/day × 125 days/year = 5,000,000 BTU/year
Btu per hour (Btu/h) is sometimes used in North America and the United Kingdom - the latter for air conditioning mainly, though "Btu/h" is sometimes abbreviated to just "Btu". [18] MBH—thousands of Btu per hour—is also common. [19] 1 W is approximately 3.412142 Btu/h [20] 1,000 Btu/h is approximately 0.2931 kW; 1 hp is approximately 2,544 Btu/h
