Hybrid Water Systems – New Tech for Ensuring High-Efficiency Water Heating

Between 17% and 20% of the energy requirements of the average home is used on heating water. This is the second highest component of energy consumption in the home. This inconvenient fact has until now remained largely ignored by the authorities but now there is a drive to improve the energy efficiency of the water heating in homes. If you have an older water heater in your home it is almost certainly very inefficient and you will reap significant financial rewards when replacing it.

Relatively New Technology

Hybrid water heaters feature relatively new technology and they are certainly very effective. Although they are considerably more expensive than regular water heaters, they can save hundreds of dollars in energy costs every year.

Hybrid water heaters boast a combination of tank and tankless water heating technologies. The hybrid water heater, unlike the tankless water heater, has a tank so that you never have to run out of hot water, overcoming the problem that households with traditional tank systems and small tankless systems sometimes have to deal with. These systems are highly efficient using sixty percent less energy than standard tankless water heaters, and they have the lowest cost to heat water of any unit on the market today.

Two Heating Systems

Hybrid water heaters typically contain two heating system. The electrical element system and a heat pump. Heat pumps use electricity to move heat from one area to another rather than creating heat. A hybrid water heating system works in a similar fashion to a refrigerator but in reverse. A refrigerator sucks the warm air out of the box and drops it via the condenser into the surrounding area outside of the refrigerator.

The heat pump removes heat from the surrounding air and then uses that to heat the water in the tank. A fan blows air from the room across coils that are filled with refrigerant gas, and the refrigerant gas along with the compressor causes a rise in temperature which is transferred to the water. When the demand for water is highest the system can switch to standard elements for heat.This is why these products are referred to as hybrid systems. You can use the control panel on your hybrid water heater to choose the mode that you want and to set temperatures. Many have a number of settings and a selection of energy efficiency modes.

Considerations When Purchasing a Hybrid Heater

It is important when buying a tank heater to consider the first-hour rating. When purchasing a tankless heater, it is the gallons per minute that will inform you of the amount of hot water a water heater can deliver. The first-hour rating tells you how much hot water the water heater can provide you in one hour.

The heat rate recovery is also an important consideration. These water heaters take a while to reheat when they are totally emptied, so take this into consideration when making your choice of water heater and rather buy a water heater with a larger tank. A fifty- gallon heater usually has a 23-gallon recovery rate so it will take just over two hours to provide you with a full tank of water again. These heaters are often larger than a standard tank unit so you should ensure that the one you plan to purchase will fit into the available area before ordering it. The unit will also need at least one thousand-cubit meters of air around it.

Your Location Does Have an Effect on the Performance

The performance of these heaters varies but even in colder areas where the backup elements are used more frequently, they offer significant savings in energy when compared to standard water heaters. The bigger the water heater the more energy efficient it will be. The installation location is also important. In colder areas, these water heaters are more efficient when installed in a basement and in warmer areas a garage or well-ventilated area is the ideal position for the heater. The air filters on heating pumps must be cleaned regularly, but this is easily achieved by simply removing it and wiping it down with a damp cloth.
