Wide selection Stiebel Eltron Tankless water heater

Tankless water heater Stiebel Eltron  offers tools to address any problems associated with water heating. The smallest outdoor tankless water heater has a capacity of 200 liters, the largest – 3000. In addition, some devices can be connected in parallel or sequentially. Therefore, whatever amount of hot water is not required, the technique Stiebel Eltron tankless water heater able to provide its preparation. Breadth of scope a designer may be limited opportunities to the local mains. Of course, the need to pre-arrange to have enough working space for the very bulky devices.

Also, consumers will appreciate the rich choice of devices on the engine power characteristics. The power spectrum of the heating elements, the proposed STIEBEL ELTRON, lies in the range from 12 to 36 kW. Moreover, the maximum power of the heating flange is not always identical to the maximum, which is capable device. Different models of storage water heaters SB series are not alone, as usual, but two or even three-flanged openings. This is the unique devices SB – they are flexible. Suppose you set the device volume of 600 liters of SB with two holes under the flanges. To ensure all existing water pumping points you had enough of a heating flange capacity, for example, 18 kW. But over time, additional demand for hot water. Usually in this situation have to buy a new more powerful device, but only if it is not the heater SB. Enough to buy another flange suitable power – the need is satisfied at minimum cost.

In one unit SB 650 / 3 AC, if there is such a need, you can install three flange with TENami power of 36 kW. This is too much for storage water heaters – in fact, it will work as a flow. This water heater provides continuous hot plumbing in the sports hall or bath luxury with multiple Jacuzzis and showers.

Floor Storage SB (unlike SHO) series is not equipped with heating flanges. Heating flanges FCR various capacities and diameters (180 mm, 210 mm and 280 mm), in general, a separate product. They are used not only in devices Stiebel Eltron , but also in storage water heaters of other firms. Flanges FCR does not require additional automation – all necessary pre-provision. Flanges are the heating function of a reduced-night rate, automatically or manually switched to full power if the bulk of the hot water was depleted. In devices SB series can also install heating element BGC (from 1 to 6 kW) for a more uniform heating of the upper part of the tank.

The only “small” from the  water heaters STIEBEL ELTRON in sizes from 200 to 400 liters. This model series of SHW. They are equipped with universal TENami, so the device can connect at one and three phases. When you connect a single-phase heating element can be switched on the power of 2-4 kW, with a three-phase – up to 6 kW. The presence of universal heaters allows for switching capacity. For example, you can increase the heating rate for the period of peak water withdrawals (general cleaning, or visit relatives).

Such a wide range of water heaters on the ratio of the volume and capacity, which has no analogues in the Russian market, to find the best possible solutions to the problems of preparing hot water for everything from small cottages to industrial enterprises.

Pressure-type water heater

For pressure-type water heater required pressure that exists in water supplies. He had no special problems connected to the central or autonomous water supply system, and can operate at several points of water pumping at the same time. This heater is ideal for urban apartments during the summer off with hot water. Check water heater for a long time served, be sure to install mechanical filters. By the way savings do not require special fittings, they are working on that which already exists in the system. This greatly simplifies installation and setup.

Floor the gas and liquid fuel water heaters

Gas water heaters – is the most common type of water heaters in the world. About 90% are sold in Seattle, namely gas water heaters. All outdoor water heaters can be divided into two main groups: with atmospheric and forced-air (sometimes referred to as exchangeable, fan, mounted) burners. The first – a simple, cheap and quiet work. water heaters with forced-air burners have higher efficiency and cost more. In water heaters for use with forced-air burners possibility of installation of burners, running on gas or liquid fuel. Range of floor and the universal gas (gas and fuel oil) water heaters is very wide. Available in both single-and double-pressure water heaters. The latter are of two types: with built-in water heater and with integrated coil (for hot water in a flow mode).

For any single-water heater for hot water water heater can connect indirect heating (water is heated by coolant water heater). There are combined water heater in which water can be heated and the water heater, and the tankless gas water heaters Takagi. Gas water heaters are single-stage (working on the same power level) and two-stage (working on two power levels) as well as with the modulation (smooth) power.

The main advantages of two-stage water heater:
• increased lifetime by reducing the frequency of inclusions (off) burner for about 70% (shown);
• Save gas while working on the first stage with low power and reduce the number of inclusions (off) burner;
• Reducing emissions of flue gases and hazardous substances;
• expanding the opportunities for use in conjunction with the water heater water heaters of various capacities.

An even greater effect is achieved by using a water heater with modulation of power.

Type of historical heaters

At the same time the formation of legionella bacteria in water temperature from 30 to 60C (namely, such temperature continuously observed in the first two types of heaters) (Fig. 2) makes manufacturers equip their water heaters with additional devices, capable of radiant heating water once a week to 90oS for destruction formed Legionella (Buderus, Vaillant).
Naturally, this leads to a complication of automation, reducing cost of the Tankless water heater and the loss of such important advantages of the first type of heaters, such as simplicity and low cost. Yes, and incomplete removal of scum from the surface radiant heating leads to a reduction in efficiency by 20% for every 2 mm scale.
