The energy saving of air source heat pump water heaters is reflected in its principle. Ordinary electric water heaters use electric heaters to directly convert electrical energy into thermal energy, and their maximum energy conversion rate will not exceed 100%. Air source heat pump water heaters use principles similar to home heating and cooling in winter to transfer outdoor thermal energy into hot water. From the perspective of energy conversion, the conversion rate is higher than that of ordinary electric heaters.
To make a simple analogy: the principle of an ordinary electric water heater is equivalent to the principle of a household electric heater, while the principle of an air source heat pump water heater is equivalent to the principle of a household heating and cooling air conditioner for heating. Heating and cooling air conditionersDomestic heaters can be used in general living areas, but electric heaters are only used in smaller rooms such as bathrooms. Indeed, if electric heaters are used in ordinary living rooms, the energy consumption will be quite alarming.
Which heater is the most efficient and saves electricity
There are direct heating and indirect heating. For example, ordinary integrated solar water heaters heat water directly; While split-pressure solar water heaters heat water indirectly, they generally use a circulating working fluid (antifreeze). The collector absorbs heat from solar energy and first heats the circulating working fluid. , which passes through the water tank. The coil or jacket exchanges heat with the water in the water tank and continuously heats the water in the water tank par natural or forced circulation.
My family lives in a rural area. How can I keep the house warm in winter when no one lives there?
Electric heaters with good heating effect and energy saving include European heaters. Rapid heating stoves, oil heaters, PTC heaters, quartz tube electric heaters, halogen tube electric heaters.
1. European Style Rapid Heating Oven
Advantages: Relatively new technology, using a black tube heating element. The overall room temperature rises very quickly, the thermal efficiency conversion rate is quite high, and there is no open flame, no noise, no oxygen consumption, and no odor during operation. The appearance of the machine is safe and not hot. touch. For living and bathing purposes. The service life is relatively long and the quality is very stable.
2. Oil heating
Advantages: A very traditional electric heating, using thermal oil for heating, with very stable quality and high thermal efficiency conversion rate. There is no open flame, no noise, no oxygen consumption and no odor during operation.
3. PTC heater
Advantages: It uses PTC ceramic heating element, which has a long service life, the ambient temperature rises quickly, no open flame, and some models can be used at once. at home and in the bath. Suggestion: Since the fan is used to dissipate heat, there will be noise during operation.
4. Quartz tube electric heater
Advantages: Using quartz tube as heating element, it is economical, no noise, the machine is small and does not take up space. Suggestion: the thermal conversion rate is not high, the duration oflife is not too long, the machine is bright when working, the local temperature increase is okay, but the overall temperature increase is not good enough.
5. Halogen Tube Electric Heater
Advantages: Using halogen tubes as heating elements is economical, quiet and has a better heat conversion rate than quartz tubes. Suggestion: The thermal conversion rate is not high enough, the service life is not too long, the machine is bright when working, the local temperature increase is okay, but the overall temperature increase the temperature is not good enough.

Purchasing tips electric heaters:
Regarding the intermittent use of heating equipment in Guangdong, consumers are recommended to pay attention to the purchaseat the request when purchasing. process.
“If there are only a few people in the family, you can usually buy a small sun; if there are elderly people or children at home, you can consider electric oil heating if you have higher requirements; the use effect, you can buy a European rapid stove; and For consumers with large apartments, they can use the European rapid oven and the small sun together. "
If consumers want to save electricity, they can turn on the air conditioning and heating for 20 minutes before using the heating equipment. Let the heating cover up quickly, but he does not advocate the simple use of air conditioners “Air conditioners will accelerate the loss of moisture in the air, which is detrimental to the air. human health."
There will be very humid and cold air in rural areas whereno one lives. You need to burn the kang in advance, increase the indoor temperature and ventilate the room before you can move in. You can only use a kang fire to heat yourself. If you are in the north, you must use a little sun to heat you. You can also use Airmate ceramic heaters as shown in the picture. If you are in the south, you must use a fireplace to keep warm. As a temporary measure, if you have to live a long time, choose solar water heating.
