If you are using a heat pump then you want to heat during the warmest part of the day. So I run my water pump maybe 9 am to 5pm. Then the heater will cycle on and off during that time. If a heat pump has 100,000 BTUs when it is 80 degrees outside that might fall to 80,000 BTU's when it is 50 degrees outside. Now some people get a 40 or 50% break on their power at night. Then I would run the heat pump at night as the savings in power makes it worth the reduced BTU's. If you have a gas or oil heater it really doesn't matter as they both heat the same day ot night. If you have a 400,000 BTU gas heater you really are putting about 330,000 BTU's in the water as the rest goes up the exhaust. That will be the same day or night. A blanket on the water will help keep in the heat though and might cut your heating bills over 50%.
A material that would make the most efficient hot pack for providing heat therapy is one that can retain heat for a long period of time, such as rice or flaxseed. These materials can be heated in the microwave and will stay warm for an extended period, providing consistent heat therapy.
weather and time my friend...weather and time.
No it doesn't, Night time heatloss is a big problem for pool heaters, as your pool pump runs it moves heat away from your pool, so you actually increase the night time heat loss by running your pool pump/heater at night. The most economical solution is using a Solar cover and leaving your pump off at night to prevent night time heatloss and then just fire up your heater when the temperatures begin to come back up to daytime levels.
It depends. Your heat pump may be undersized. Using a pool cover will keep the heat you make from being lost at night and cut the cost of operation in half. It is more efficient to run the heater only during the daytime. You may want to consider using "solar" as a supplemental heat source. Yes, if your pool heater has been wrongly sized to your pool configurations you will end up spending more for your gas bill than someone with the exact same pool and use habits as yours but they have a much larger BTU heater. The larger heater will heat the water faster or in less time than a smaller heater would and would have better recovery as pertaining to water temps. Longer heater run times require more gas consumed. Expense, even for those who can afford it, is of concern for most. Depends on your priorities and budget. ----- Hold on now, the amount of heat required to keep a pool at a given temperature won't depend much on the size of the heater, but rather the total amount of energy used. The heater should be an appropriate size running for an appropriate length of time, but your total cost will mainly be determined by pool size, temperature desired and heat loss factors. If your pool heating bill is too high, cut the temperature a little and check the timing relative to when you actually use the pool.
Better, in a heat efficient way, because there is no loss of heat, with a real one,you need to vent exhaust fumes and at the same time you lose heat. A real fireplace looks better but is less efficient.
Even assuming that you live in southern California, why would you want to heat your pool in the winter? If you are actually swimming year round it might be more economical to heat the pool continually. Your pool will loose up to 15 degrees overnight making it harder for the heater to maintain a constant temp. Your heater will expend more energy ~ waste fuel ~ just trying to make up the lost heat than it would if you ran it all the time. My thinking is that you are a very wasteful person to use up resources. Money must be of no concern for you as I think it must be costing close to or even exceeding $800 per month to heat a pool even in Calif. Also, even if you have an extremely efficient pool heater you are still adding harmful gases to the environment. How inconsiderate of you.
Assuming all other factors are equal, a swimming pool will heat up faster than a bathtub. This is because a swimming pool has a larger surface area exposed to the heat source, allowing for more efficient heat transfer. Additionally, the volume of water in a swimming pool is typically much larger than that of a bathtub, meaning it requires more energy to raise the temperature of the entire pool.
Early morning or in the evening or even at night; heat and sunlight reduce the effects of chlorine or other shock methods.
The most economical way to heat an inground pool is to use a solar pool heater. Solar heaters provide a cheap efficient and eco-friendly way to warm up your pool. Here are some of the benefits of using a solar pool heater: Inexpensive to install and maintain No need to run electricity Heat pumps can be used to supplement the solar heater No emissionsA solar pool heater typically consists of a series of tubes or panels that are installed on the roof or ground depending on the design. Water is pumped through the tubes which are heated by the suns rays. The heated water is then returned to the pool thus raising the temperature of the water. In addition to using a solar pool heater you can also consider using a pool cover to keep the heat in and reduce evaporation.
In order to reduce electricity consumption (and potentially reduce electricity expenses) it is advisable to turn off pool-heaters until the time at which the pool is to be used. So as to have a pool at a suitable swimming temperature, it would be advisable to turn on the heater a number of hours before you intend to swim in the pool. A more amount of time your pool takes to heat thoroughly may be available in documentation you have regarding your pool.
Most of the time it can be stretched and reattached. It takes a little time and you may think it is invane but keep trying.
No it should not, I live in the Las Vegas area and only run it 8-10 hours per day. Even on the hottest days. Use this product and run your filter even less http://www.thecirculator.com/fnb.php
