Tankless water heater is also known as fast hot or demand water heaters, the basic characteristics of the tankless gas water heater are: the cold water flow over the water tube then water is hot water, as long as you turn on the faucet, within a few seconds, an endless continuous supply of hot water is possible, if you do not use hot water, just need to turn off the tap.
Tankless Gas Water Heaters
The tankless gas water heaters can be divided into four kinds: gas water heater flue strong emission, thermostats and condensing. The flue type: big exhaust port, thick smoke tube and poor lodging resistance wind. Outdoor air flow through the thick smoke tube is easily blown into the water heater cause accidental flameout or damage to the water heater down burning, it cannot be installed on the high floors due to the open combustion chamber efficiency is not high, and energy efficiency Level three, is now in the phase-out period. Strong emission type: it is on the basis of the flue machines increased a strong exhaust fan, the fan is the water heater outside air drawn into the combustion chamber to help burning (combustion efficiency. Energy efficiency rating of two) at the same time burning after the mandatory emissions exhausted to the outside. Pressure is high in the water heater and the exhaust port smaller outdoor end is connected to dedicated windproof cigarette tubes, it can be installed in a high apartment elevator. Condensing type: the role of the condenser is energy efficient. Condenser temperature machine is based on a condensing heat exchanger. Its role is to present the high temperature exhaust gas is discharged outside the machine is recycled to the condensing switch once again absorbs heat, while the high temperature exhaust gas in the condensed water separation heater out to protect against corrosion, to extend the water heater life.
Tankless Electric Water Heater
Tankless electric water heaters can be divided into: "metal tube", "glass tube" genre, cast aluminum "genre and semiconductor ceramic" genre. First, "the metal tube" tankless water heater, the "Metal tube" genre enterprises constitute the main components of the instantaneous electric water heater heating element materials by metal camp. The main products of this type in the market have stainless steel hot water heater and copper hot water heater. Compared with the stainless steel, copper has good ductility, and it can be made into strengthen Seamless Copper Tube, thermal conductivity, and can effectively prevent leakage, leakage, but because of the copper price is higher than stainless steel, For the sake of cost reasons, the majority of enterprises are made of stainless steel as a liner and heater. Secondly, the glass tube "genre. Glass tube "genre refers to enterprises constitute the main components of the instantaneous electric water heater heating element materials from non-metallic camp. Major non-metallic heating element in the market by the crystal (quartz), glass, ceramic made of three materials, non-metallic pipe outer wall made of non-metallic materials with high temperature sintering.
