What Are BTUs: Pool Heater Thermal Units? BTU, which stands for British thermal unit, is how pool heaters are sized. One BTU (sometimes also written as Btu) is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. ...
…and many more.Standby power is convenient — many modern appliances require it to perform their primary function — but that convenience comes at a cost.Often, phantom loads are as much a result of poor design than necessity.It’s estimated that 5-10% of residential electricity consumption ...
So, if we divide 30,000 BTU into 91,500 BTU, we get 3.05. That is how many hours one gallon of propane will last when used by a 30,000 BTU heater. This means that in just 1 hour, that same heater will use approximately 1/3 of a gallon of propane. ...
According to the Department of Energy, more than half of a typical household’s energy use goes toward heating and cooling. While a heat pump is far more energy-efficient than a traditional heating system (and many air conditioners, too), it’ll still be the most energy-hungry appliance in...
when it is in place. It isn’t the water loss that’s the big consideration heres the heat loss. Every gallon of water that evaporates from a pool takes with it 6000 BTU’s of heat in the processand a typical uncovered pool loses 1 to 1½ inches of water a week through ...
Use the following formula to determine the Btu/hour output requirement of the heater: Pool Area x Temperature Rise x 12 This formula is based on 1º to 1-1/4ºF temperature rise per hour and a 3-1/2 mile per hour average wind at the pool surface. For a 1-1/2ºF rise multi...
In many cases, it is the home builder rather than the homeowner who selects the heating system. Builders are often driven by different priorities from those who will live with, maintain and pay for the operation of that system. People who have lived with uncomfortable heating systems don’t ...
However, Mr Bailey advances no rational case. What, then, are the elements of a rational, scientific case that our influence on the climate will prove dangerous unless the West completes its current self-shutdown? Here is the mountain the tax-gobbling classes who tend to favor profitable alarm...

Taking this into consideration, an important point for pharmaceutical use concerns the need of a more precise and sensitive control of the heater's temperature (Figure 4g). Overheating could lead to modifications of the polymer viscoelasticity compromising drug control release and, eventually, stability...
