The choice of one or the other option depends on many factors, notably of bathroom accessories, the number of inhabitants, their habits, as well as the size of the building and heat loss. To make the right choice, you need to know the opportunities that will give us a wall-hung boiler with built-in tank, and what with separate, as well as the properties of each device groups. co-fired boiler with a separate single-function e.g cooperating with a separate tank The name of this device can be misleading. Often heard it the first time we have the impression that this kind of boiler is no heating hot water that is used only for central heating. The origin of this name stems from the fact that the only liquid in the boiler water heating installation as The boiler performs only one function so that it is raising the temperature of heating water. Only later the water is directed once for central heating, and once the coil in the DHW cylinder. In this way, once heated the house, and once water use. Boiler actually fulfills only one function (raising the temperature of water in the system), but in cooperation installation and DHW cylinder provides us with a way two functions - building and water heating.

If you need help with your installation then try builders.plusinek and you live in South Acton then help is at hand, other locations include West Ealing, in fact good help is on offer anywhere in the Ealing location including Acton and East Acton. Specialist cover all grounds of boilers and when they do their work they leave no stones unturned. Updated at 01.22 on 31.10.2014:

Modern fired boiler is generally well equipped. Often contains elements of the installation, which used to be mounted outside the unit. These include, for example, driver safety valve or diverting valve that directs the water heating system to be installed at or the coil tray. Therefore, simply connect to this type of boiler DHW cylinder, commonly called tank to be able to get the implementation of both home heating and hot water.

With a reservoir of sufficient size can be used in this case boiler low power heated surface adapted to house. Although the low-power boiler will have to work longer to heat hot water heater, but with a considerable store of hot water, we can freely use it even in the two bathrooms and the kitchen.

With low-power boiler, adapted to the needs of thermal building will perform with high efficiency, individual cycles are longer, and the number of starts less. Thanks to lengthen the life of the boiler.

This solution also has some disadvantages. Can include them primarily larger space, which occupies a total boiler, extra tray and necessary equipment. In addition, the connection between the boiler and the storage tank is an additional installation to installation, which costs.

boiler hanging with built-in two trays of hot water? hanging dual-function with built-in storage tank One solution to the problems associated with finding a place on a large tray can be the use of compact wall mounted boiler with built-in storage tank already. Such a device despite the slightly larger dimensions of an ordinary boiler mono functional can heat large quantities of water and without the cooperation of a large hot water tank This is due to its construction and performance. The basis of this is the combi boiler, that is, one that within its enclosure performs two functions - heating water and power plant at It has a built-in, a special heat exchanger, in which the flow, to keep the intake water is heated by the heating water. To achieve high performance used in this case high-power boilers, generally greater than 24 kW, up to as much as 35 kW, which allows us to constantly collect water in an amount of from 11.6 to nearly 17 l / minute (when heated water from 30 ° C).

It is therefore free to fill the tub, and even the parallel use of two showers in the bathrooms. However, this is not always a sufficient level of comfort, particularly in the case of a boiler with a capacity of 24 kW, and in parallel using a number of receivers it is not possible to obtain a suitable temperature. When, for example. One member of the household takes a shower, and the other at this point will benefit from the tap in the kitchen, it can cause a temporary fall in water temperature in both these points. Hence, in order to avoid such surprises in the compact boilers, an additional, small water heater It is usually capacity from 20 to as much as 50 liters, and its task is to cover temporary, large consumption of hot water. In the case of an ordinary combination boiler with a capacity of 20-24 kW would immediately cause a decrease in water temperature. The temperature will be maintained through the store near the hot water in the water heater. While a large collection of hot water will be gradually exhausted, and after the intake of water is replenished.

This combination of substantial power from the mini combi boiler hot water tank gives you great opportunities. With direct heating of water and the use of the inventory of boilers compact tray once (in the first 10 minutes) can provide us with even 200-250 l of warm water. For comparison, so we may provide a separate reservoir with a capacity of only 150 l heated to a higher temperature, respectively. Seemingly smaller device, which is hanging boiler compact, provides sometimes more hot water than the boiler with a separate, large storage tank. Thus, it seems that this solution is ideal. It is enough to apply this type of boiler to get the right amount of water, even for the two bathrooms in the house. In addition, due to the small size we can put eg. In the kitchen or bathroom.

As a result, we have a high comfort of hot water and more space in the boiler room, which can be exploited for other purposes. Before deciding to choose this is a solution but we need to know about a few shortcomings. First of all, in a small house with low heat losses have to remember that using a combi boiler with a capacity of 25 kW, for example, install the unit with a capacity of 2, and even 3-fold higher than is needed to heat the home. The result will be short cycles of operation. In the short time since the launch of the burner boiler reaches the desired temperature and turns off. After some time, the again and again will work very shortly. This may adversely affect the efficiency and service life. In addition, the cyclic operation of equipment, especially boilers weather is quite loud and interferes with users.

While working for the needs of hot water boiler compact with built-in storage tank will run much more frequently than the boiler with a separate storage tank. This is due to the use of a compact boiler tank of small capacity. For this reason, often even wash their hands or cups will start the boiler, which is not the case of a device cooperating with a large, additional storage tank. This way of working can also shorten the service life of the boiler. To know more check out the Boiler Repair Land.
