Heating Water For Domestic Hot Water Or To Heat Your Home
Water is heated for two purposes in residential applications. The first is to heat water for domestic use. Such a cleaning, washing, cooking, showers and bathing. The second is to heat water to be a medium for carrying that heat to a room then releasing the heat into that room to keep us warm.
Water heater hot water tanks
Heating water for domestic use is done with hot water tanks, tankless water heaters, or indirect water heaters.
Tankless water heaters
Tankless water heaters are becoming more common in North America, although these have been used in other parts of the world for years. This kind of water heater does not have any water in a tank. If you do not have a tank then you will not have to continually keep that water heated as the water will always cool even when not in use. The cooling process is caused by heat from the water warming the air in the flue, then the hot air rises and is displaced by cooler air which is in turn heated by the hot water . This air will flow up the flue and spill out into the room. Also the water in the tank will cool as heat conducts through the tank and into the room. This cooling process is called standby loss and because of this process your water heater is at best 55% efficient.
Tankless water heaters are more efficient than hot water tanks because of the heating process. A hot water heater will heat the bottom of the tank and the center of the tank, with most of the energy leaving the tank up the flue. Where as a tankless water heater heats a coil of pipes inside of a heat exchanger similar to that of a boiler. This heat exchanger is made up of small tubes that heat up very fast.
A tankless water heater will also modulate the burner. So if you need only a small demand the tankless heater will only give you a small flame. And if you need a larger demand a tankless water heater will give you a larger flame.
Hot Water Tanks
Hot water tanks are the most common form in North America to heat your domestic water. These tanks have been around for a very long time and have not changed much until recently. Most homes use a 40 to 50 US gallon water heater. Between high energy costs and pollution many people are switching to better ways to heat there water.
A hot water heater requires a chimney for the flue gases to flow to the outside . Water heaters also have an anode rod to protect the tank, a dip tube to allow the cold water to flow to the bottom of the tank, a gas valve, burner and a relief valve. NEVER plug a relief valve. This is the largest cause of water heater explosions. Water when heated to boiling changes to steam. When this happens the water expands 1700 times and with no where to go the tank has to blow up. Usually the bottom is what bursts and the water heater becomes a rocket shooting through the roof in a two story building.

Indirect water heaters--An indirect water heater uses a boiler to heat the water that flows through the inside of a coil of pipe which in turns heats the domestic water through conduction. These are very efficient, have a fast response time and out last a standard water heater more than three to one. The response time is very quick giving you more than enough hot water. In my opinion these are the best water heaters on the market. The biggest problem is that you need a boiler to heat the water therefore the cost can be high compared to a normal water heater. If you are renovating and going to install hot water heating of any sort, such as a fan coil instead of a high efficient furnace, then this is the way to go

Solar Heat Exchangers Heating Your Home With The Power Of The Sun
If you are interested in harnessing solar power for solar heat in your home, but are not quite in the position to be installing solar panels and a large solar heating system, you should consider using a solar heat exchanger. Solar heat exchangers are great for heating your home in many different capacities. They are also usually quite affordable.
Did you know that heat exchangers are used throughout your home already? They are commonly found in cars, refrigerators, and air conditioners and they regulate the heat that is generated and used in these items. They prevent over-heating and transfer the right amounts of heat to the right places. Solar heat exchangers are essentially the same, but they transfer the sun’s heat instead of heat generated by an appliance or engine. They usually use liquid and air to transfer heat to another area, such as your swimming pool or your hot water tank.
One of the most popular types of solar heat exchangers is a swimming pool heater. These are great for any swimming pool owner. As you may know, heating a swimming pool can be expensive and consumes quite a bit of energy. If you don’t want to give up your heated pool, but still want to be environmentally friendly, you should look into installing a solar heat exchanger.
Another type of solar heat exchanger is one that works to heat smaller areas, such as hot water heaters and sheds. These heat exchangers are great for those individuals that want to use solar heat, but do not want to spend a lot of money. These come in a variety of styles and sizes, so you can choose one that suits your needs.
Learn the pros and cons of solar power - Solar Energy Advantages is your source for information on solar panels, fountain pumps, home solar plans and information on how solar power works and can benefit your home and family. One of the ways that you can use solar heat without spending too much or converting your entire home to solar heating is with a solar heat exchanger. These are available for a wide variety of uses including heating swimming pools, sheds and solar water heaters.
