The water in the tank is cold. This is condensation dripping down on the burner formed when hot air touches the cold tank. \n\nOnce the water is heated it never gets cold again so you should not hear it again.\n\nGet an "A"

Reverse Os can be obtained just like de ionzing water,they make systems just for that pupose for portable auto wash systems.there are several web sites for water control systems,all price ranges.i would start with a simple search of ,portable wash systems or power wash,pressure wash you ll come across links in there that can help you buy or build your own.they even have plans for using a basic water heater,such as the type in a household use.depends what your needs require.hope this was helpfull i have to treat water before i clean certain surfaces.

Depends so much!  Are you paying for gas and/or electric?  Do you need to pay to heat your water?  How big is your place?\n\nI am really cheap on the electric-- my bill is usually 25 bucks a month (two bedroom) and gas (to heat) has varied from 10 (summer) to 50 (winter).\n\nI plan on an average of 50 bucks.  \n\nActually, the best way to do this is to find the place you're interested in.  Then you find out what gas and electric companies the prior tenant used.  Then you call and ask them the averages and highs/lows.  They can give out this information to help you plan.

You can make a great solar water heater with a small 12 volt water pump which you can purchase from any RV dealer. Put the intake into the pool and connect the out side to a long length of garden hose. Lay the hose in the sun or on the roof and back into the pool. The longer the hose, the warmer the water will be.

More than likely a chlorine gas I would rec. NOT experimenting with the two. I work in the water treatment field. Trust me

If the element is bad it will take forever to heat hot water back up. I would check that first before you put alot of money into it. Hope this helps.

You can make Kerosene for fueling your heaters.........\nand roof patch and driveway sealer.............

I suspect you may have to install seperate systems and in respect of central heating you would have to have isolation valves to allow transfer from pressurised to gravity fed system - it would be complx but technically acheivable - I currently run two seperate heating systems in a now combined house (formerly two) and have considered this.\n heating of mains pressure water via wood stove boiler and or solar would be difficult and therefore a gravity fed system would be required.\nThorough planning and installation of switching options is required

I think you should keep it simple yet smart. First get a piece of pure elemental Sodium and then let it drop on warm water. Afterwards explain how the chemical reaction released Sodium Oxide and Hydrogen Gas.

Steel is the most common. Hot water heaters are steel tanks with a glass or 'stone' (Hydrastone (R)) lining to prevent corrosion. Cold water tanks may be made of heavy guage plastic. Underground cisterns are typically build of concrete blocks painted with a cement coat, or made of concrete.

It depends on how hot you want your water. If you want only moderately heated water, suitable for bathing, you can use a box covered with glass that has a long winding pipe inside it. The pipe should be a small diameter and laid out flat on the bottom of the box with as many turns in it as possible to increas the length. This can go into a reservoir, like a hot water tank, and to make it more sophisticated you can put a circulating pump on the tank that constantly circulates the water through the heating panel. This is how commercial solar water heaters are made, with some sophisticated controls added. \n\nIf you want to boil your water using solar power this can be done with a parabolic mirror that focuses sunlight onto your cooking pot. These can be made from small pieces of mirror laid in a parabolic form (shaped like a satelitte dish) and cemented with plain grout. I have seen these used in some areas and they are quite effective. \n\nOne simple method that I use when camping: Lay a black colored bag of water on the ground or hang it in the sun and wait till it is warm enough for a shower.

First of all, what you are proposing is very dangerous. Doing this indoors will require a linked active exhaust fan and vent. In other words you can not turn on the gas without the vent fan operating and should the fan fail, the link would turn off the gas automatically - no if's, and's, or but's. Should the gas be on and the pretty dancing flame get put out, the next open flame or spark the gas finds turns the house into matchsticks. Second, your ring of fire will heat the glass with an excellent chance of breaking it depending on the size of the tank and thickness of the glass. You see, the glass under the water will remain cool while the glass above the water is allowed to heat up, now the glass becomes very stressed because of the differing expansion rates within the same piece of glass. This makes this a dumb idea even outside. You know what - I think I just talked myself out of telling you how to do this, sorry.
