Tankless water heaters

Gas water heaters

Gas water heaters

In the residential water heating system, accommodation often equipped with special heat sources – well-known and long gas water heaters (boilers) DM AGW, AUGV, AOGV. All of these heaters on and off the main burner (by opening or stop the flow of gas to the burner) are carried out automatically by the thermostat.

AGV – capacious water heaters to 80 and 120 liters, the power of 7 and 29 kW at an efficiency of 81 … 83%. AOGV – is small and metal content.
AKGV – dual function apparatus destination: for space heating with heat losses to 18,5 kW, and at the same time for hot water flats.

Gas tankless water heaters

They are used in air heating systems of buildings as additional sources of heat in combination with other heating systems installations. Here the heat of combustion is transferred wholly or partially cold outside air, heated by the apparatus. In the heat transfer through the wall of efficiency ramjet, or circulating air reaches 70 … 90%. In the mixing apparatus by direct mixing of combustion products and heated air increases the efficiency up to 100%. Known direct-flow heaters relatively low power (50 kW, 70 … 2000 m3 / h at a temperature of 50 … 700 C) and more powerful (450 kW, up to 16000 m3 / h air at a temperature of 100 … 1100).

Tankless Water Heaters for summer season

The absence of an autonomous water supply leads to a seasonal dependence of preventive operations in local Tankless water heaters. A month or even more, in the heat of it is that hot water tap shows no signs of life. There is a lockout, which, unfortunately, can occur at any time of year. In order to, without feeling the slightest discomfort, be able at any moment to take a shower or wash the dishes, we must take care of it beforehand. For such emergencies STIEBEL ELTRON offers a variety of water-radiant heating devices, choosing from which you can solve the festering problem once and for all.

Compact water heater if it is a temporary move to “own resources” does not make sense to buy the giant water heaters with an enormous power. It is quite enough of the smallest of the 150 models of devices offered by the German concern. First of all, we should think about instantaneous water heaters, allowing a simple turn of the handle to get an unlimited amount of time in hot water.

DHC – a series of small instantaneous water heater with hydraulic control, with a rated capacity of 3 to 8 kW per phase. Designed for one or more users, such as kitchen and washing. Like other protochniki, DHC ensures hot water immediately, without preparation. The ideal application of this series in cases where often require a small amount of water. Additional convenience is, in particular, that when you connect to does not require special fittings, you can use an existing faucet. Some models can be installed under the sink. Installation does not take much time, and compactness of the device (200/360/104) will install it anywhere. The temperature of radiant heating water from 35C to 85S, turn the heater with hydraulic automatic and has two levels of power, set manually switch on the body. Possible to switch the power, for example, 4,4 kW / 8,8 kW, 6,6 kW / 8,8 kW. In principle, DHC will work in the winter, but low-power model is preferable for the summer time, when water in pipes has already reached 10-15C. If DHC, acquired in order to take a shower, it is better to choose the most powerful instrument. The usual shower head (the difference between the number of liters, pour in a minute – 12-16 l / min and 8-10 l / min) is recommended to change to the cost, with a small cross section. In this case STIEBEL ELTRON promises quite a comfortable shower. All units have a copper heater and the inner copper flask, which means reliability. Indoor radiant heating element resistant to the “air locks”, common in the domestic water system, open spiral in this case simply burn out, there is protection and overheat.

If demand for hot water exceeds the capacity of instantaneous water heaters, but still remains modest, one of the best options – a water heater PSH 30. This storage water heater with tridtsatilitrovym volume and heaters radiant heating element of the copper output of 2 kW, which allows you to include it via an ordinary wall socket. This model is one of the most popular products STIEBEL ELTRON, as developed specifically for Canada and, therefore, takes into account all the local features of water consumption. This water heater will replace the radiant heating plant during the summer off hot water in the apartment or office and come in handy at their summer cottage. Not least in the decisive choice among the various models occupy its dimensions: this device can be “to attach” even in the smallest bathroom (623/342/347 mm). The quality of manufacturing the device is not inferior to models increased. aluminum flask of high-alloy aluminum with thickness 3 mm covered with a special enamel, cold water on the consumption comes and heated automatically. Insulation from environmentally friendly materials effectively reduces heat loss. Magnesium anode, a rarity in this volume of hot water heaters, prevents corrosion. Within an hour the water warms up to 60C, but this is enough for a shower for one person. Enclosed radiant heating elements are recommended for soft water. But even in hard water, with an average temperature of 60 degrees, when the scale is formed is not very actively (besides, it is the most economical mode), the device will be duly served, though, and will require more frequent preventive maintenance. By the way, get it and clean heater can be independently at home. Water supply to the appliance is via a security group that allows time to reset the overpressure.

Electrical STIBEL ELTRON is recognized as one of the most reliable and durable. If all requirements for installation and operation, which includes the mandatory grounding, water heater last more than one year without failures, and each time will rescue you in the moment of crisis.
