What are the disadvantages of solar water heaters?

i think that they would probably not work without the sun and in addition to this i dont think they would make us much heat as the other heaters eg convectional heaters


Do solar pool heaters work?

Yes, they are well worth the cost.


Were do you put water for the heater on a 1999 reg corsa?

To make your heaters work, make sure you have water in the water tank under the bonnet. You cant miss it. I had that problem with a corsa sxi, I didnt have any water in the tank hense my heaters wouldn't work.


What are the comparative advantages and disadvantages of electric and solar water heaters?

Solar hot water heaters need sunlight to work. While you can store the heat and create closed loop systems that protect the system from freezing, the use of solar hot water heaters really makes sense if you have full sun exposure and are willing to moderate your usage. It also may cost more to install a domestic solar hot water system. These can run on 12v oe 11v for the pump, or you could go passive- there are many different types and options. Check Home Power mag. Electric hot water systems come in two flavors; tank and tankless. For electric tank systems, the cost of heating water with electricity can be quite large. These tank heaters store hot water and are using electricity just to keep the tank warm. This is not very efficient even with insulating blankets. Once you run out of hot water in the tank(as cold rushes in) your shower is over. The heater itself is usually inexpensive. Plumbing is straignt foward, with 30 to 40 amp 220V feed required. Tankless water heaters or "on demand" water heaters (both gas and electric) are fantastic! They are the least expensive to operate, and fairly simple to install. The electric tankless heater requires no exhust ducting and is perfect for under the counter usage or with larger units can heat the water for an entire home. The tankless design never runs out of water! These are perfect for solar installations that may encounter weeks of cloudy weather. The units are more expensive than tank heaters, and usually require 220v service (if electric). if your doing reseach on this great if not get a life losers


Will gas hot water heaters work without electricity?

Yes, they are GAS tanks, NOT electrical


How do tankless water heater devices provide sufficient hot water?

Tankless water heaters work by quickly and efficiently heating water as it is demanded. They provide sufficient hot water because the heating implement goes on while water is turned on, avoiding the energy waste of tank water heaters.


How does a solar water heater work?

How does a solar water heater work?Solar water heaters do three basic operations before the hot water comes out of your faucet: 1. Energy Collection:Sunlight, short wave energy, is collected and converted to heat which is long wave energy energy. The solar collector is mounted on or near your home facing south. As the sunlight passes through the collector's plastic or glass "glazing," it strikes a metal or rubber absorbing material. This material converts the sunlight into long wave heat, and the glazing prevents the heat from escaping like a greenhouse. It is like leaving a car parked in the sun with its windows rolled up. The temperature inside a glazed solar collector on your roof can easily reach 300°F when there is no heat transfer fluid flowing through it. The most common types of solar collectors used in solar water heaters are glazed flat plate collectors. A glazed flat plate collector consists of a shallow rectangular box with a transparent plastic or glass "window" covering a flat black plate or selective "Chrome" coating. The black plate is attached to a series of parallel tubes or one serpentine tube through which water, or other heat transfer fluids pass. 2. Energy Transfer: Circulating fluids like water in an "Open Loop" or Propylene Glycol in a Closed Loop" transfer the collected energy in the form of heatto a storage tank. Heat energy is transferred from the collector to the water storage tank. In some water heaters, hot fluid is pumped from the collector to the storage tank. The pump is powered by electricity that either comes from an electrical wall outlet or a small photovoltaic module located beside the collector. 3. Energy Storage Solar-heated water is stored in an insulated tank until you need it. Hot water is drawn off the tank when tap water is used, and cold make-up water enters at the bottom of the tank. Solar water heaters tend to have a slightly larger hot water storage capacity than conventional water heaters. This is because solar heat is available only during the day and sufficient hot water must be collected to meet evening and morning requirements.


How does an instant hot water dispenser work?

Unlike storage water heaters where a large quantity of water is kept heated all the time, the instant water heaters heat the water during passage. It does take a few seconds for hot water to reach but it save a lot of money while saving electricity.


Do solar pool heaters use any electricity?

Solar water heaters,also called solar domestic hot water systems,can be used in any climate, and the fuel they use,sunshine,is free. Solar panels convert photons of light into electrical current by a process known as the "photovoltaic effect". This essentially means that solar energy illuminating is causing electrons in a solar panel to become excited. These electrons are then directed into an electric current by a built-in electromagnetic field. This direct current electricity can be used to power many electric loads. It can also be "inverted" to alternating current electricity which can be used to power items in a home or business.Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. Taking into account how the solar panles work we wouldn't need electricity, however most would use electricity in their back up system.


Is half inch water line sufficient for water supply for forced hot water baseboard heat?

Yes, 1/2 inch supply to fill boiler will work fine. Piping going to baseboard heaters needs to be sized properly. 1/2 inch piping to baseboard heaters not recommended. Most hot water baseboard heaters piped with 3/4 pipe.


Does solar power work under WATER?

Yes it most certainly does


Do solar water heaters work?

Solar water heaters perform three basic operations before the hot water comes out of your tap: 1. Energy Collection: Sunlight is collected and converted to heat energy. The solar collector is mounted on or near your home facing south. As the sunlight passes through the collector's glazing, it strikes an absorbing material. This material converts the sunlight into heat, and the glazing prevents the heat from escaping in a similar manner to leaving a car parked in the sun with its windows rolled up. The temperature inside a glazed solar collector on your roof can easily reach 150°C when there is no heat transfer fluid flowing through it. The two most common types of solar collectors used in solar water heaters are glazed flat plate and evacuated tube collectors. A glazed flat plate collector consists of a shallow rectangular box with a transparent glass "window" covering a flat black plate. The black plate is attached to a series of parallel tubes or one serpentine tube through which air, water, or other heat transfer fluids pass. An evacuated tube collector consists of several individual glass tubes, each containing a black metal pipe through which the heat transfer fluid passes. The space between the pipe and the glass tube is "evacuated," so the air is removed. Although uncommon, unglazed plastic collectors can be used as a seasonal solar water heating system. However, they are used mostly for pool heating. Each collector has its advantages, and each can perform well if matched with the proper, well-designed, storage unit. 2. Energy Transfer: Circulating fluids transfer the collected energy in the form of heat to a storage tank. Heat energy is transferred from the collector to the water storage tank. In some water heaters, hot fluid is pumped from the collector to the storage tank. The pump is powered by electricity that either comes from an electrical wall outlet or a small photovoltaic module located beside the collector. In other types of solar water heaters, the sun heats the storage tank directly, so the fluid in the collector is heated and rises naturally to a storage tank above the collector. This type of solar water heater is often referred to as a thermosiphon system. It does not require an electric pump. Passive solar and solar photovoltaic-powered systems will continue to operate even if there is a power outage. The products that require electricity from a wall outlet will not operate during a power outage. 3. Energy Storage Solar-heated water is stored in an insulated tank until you need it. Hot water is drawn off the tank when tap water is used, and cold make-up water enters at the bottom of the tank. Solar water heaters tend to have a slightly larger hot water storage capacity than conventional water heaters. This is because solar heat is available only during the day and sufficient hot water must be collected to meet evening and morning requirements.
