Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature. This system will be automated so you don't have to worry about running out of hot water on a rainy day.

YES! 70% to 80% of UV radiation can pass through thin clouds. On cloudy days your skin might feel cooler and because of this it is less likely you will notice you are getting burned, which can become quite a problem. It is true that the body needs a small amount of sunlight in order to produce vitamin D, however much less than it takes to get a tan.

There can be nearly an infinite number of reasons for water problems. Assuming the water has been ok up till now, some of the more common possibilities are, residual soap in swimwear, makeup or other personal hygiene products. Consider what has happened, or who has used the spa most recently. If the foam goes away shortly after turning off the jets, the cause is probably a saturation of total dissolved solids.

There could be many reasons for cloudy water. The Water Quality Assurance Lab will want to talk with you. They can answer your question. The number is 645-7691.

It could be many things such as bacterial bloom if you have a new tank or the filter has been compromised, or a white precipitate in hard water where phosphate based pH adjuster has been used. Try asking one of the newsgroups, but remember to detail your specific circumstances so the cause can be pinned down for your situation.

SPP solar systems will be able to provide heating during cloudy or overcast days, but may require the use of traditional gas or electric heating system to produce required temperatures.

Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. Approximately 25-30% of the sun's energy actually gets through the clouds.

Not necessarily. The effect of clouds on UV radiation is as varied as the clouds themselves. Fully overcast skies lead to reductions in surface UV irradiance. On average, scattered or broken clouds also cause reductions, but short-term or localised UV levels can be larger than for cloud-free skies if direct sunlight is also present.

In the larger scales and full size locomotives, coal is the most common fuel used, and some full sized loco's also use oil. In models, you have the choice of Butane gas, coal or spirit (meths or alcohol). ROUNDHOUSE standard locomotives are all fired by butane gas which is the simplest method of heating the water.

Air bubbles that have been formed during the manufacturing process can cause a cloudy appearance. These air bubbles are not harmful and will be easily eliminated with use as the water pushes the air out.

Cloudy water in a new tank is often a sign that you did not wash your gravel adequately. If you did, you may have a bacterial bloom. This bloom can be treated with products such as Acural F. For crystal clear water, an ultraviolet sterilizer is the best permanent cure.

Water can be come cloudy for several reasons, but mainly overfeeding and overcrowding. Give me more details about your set-up (what size container, how many and how big are the creatures-guppies, platy, snail, etc).

Cloudy water can be caused by improper water balance, inadequate filtration or shocking, or excess calcium. If you experience cloudy water, check the balance, try an extra shock treatment of PristinePower, clean the spa filters and increase the filtration time of your spa.

Answer : Using a hot water tank and a bolier. The alternative system of using electric heaters to heat water on-demand (the standard system in

Heated water cleans more effectively than cold water. An added benefit to warm water is I use less concentrated soaps to insure the safety of your plants.

Wind is the biggest factor in water temperature. When the wind blows from the ocean towards the land, it blows water that has been warmed by the sun towards the beach. When the wind blows from the land towards the ocean, that warm water is push out to sea, and the cold water from underneath rises to take its place at the shore. The warm water is clear because its on the surface, while the cold water that was on the bottom is full of sediment and is a murky brown.

It's actually not that cloudy here - we just have lots of nice, white, puffy clouds on most days, but sometimes our camera capture image technology can make them seem more pronounced than they really are. Top

Even when the sun isn't shining brightly, there is still a lot of energy available for your solar system to collect. Remember, you can still get a sunburn on an overcast day. Over the course of several cool, cloudy days, your pool may slowly lose temperature but will rapidly heat up again with the return of sunny weather. The use of a solar blanket is highly recommended to maximize heat retention.

Cloudy water in a hot tub or spa is caused my a lot of things & is an almost always a good sign of other water issues. If the water is cloudy AND is "older" than 3 months, change the water, you'll save yourself adding unnecessary chemicals and time. Prevention is normally the solution!
