How to turn off the heating on a Vaillant boiler

How to turn off the gas boiler

First you need to understand what the causes of turning off the boiler in the summer, and whether you need to do it at all. This is done for reasons related to saving gas. But this only appears to be the case at first sight: in fact, the frequent shutdowns affect the boiler.

This increases the wear and tear of equipment and can cause breakdowns:

  • Firstly, the longer the system is idle in the cold, the lower the temperature of the coolant and the harder it will be to heat up when igniting the boiler. Fuel consumption will be significant.
  • Secondly, it reduces the temperature of the heat exchanger as well. Droplets of water will accumulate on its surface during reheating. This condensate can cause destruction and corrosion of the heat exchanger.
  • Thirdly, water droplets also deposit on the burner. This significantly lowers its efficiency and consequently increases fuel consumption.

Corrosion of the main components of the boiler requires replacement in most cases. Unlikely to be repaired by soldering. To reduce the risk of such problems will help start the equipment smoothly after a long downtime. Most boilers have special modes of operation. If available, it is important to know how to turn them on correctly on different types of automatics and units of different brands.

Important! To save fuel, you can not turn off the boiler in the summer. There are many ways to save money. One of them is the use of modulating burners. When deciding whether or not to turn off the heating system for the summer period, you need to assess the possible risk and the amount of gas saved.

Models

The model range of gas boilers Vaillant turboTEC is represented by single- and double-circuit units of different capacity from 12 to 36 kW, depending on the specific model.

The first line is a basic model with a limited power selection. only 24 kW is available. Units in the Plus line have expanded functionality and capacity, giving the user a choice of models from 12 to 36 kW.

This makes it possible to select the unit under the available area or configuration of the home, to obtain the best design option for the prevailing conditions of work.

Convector heating pros and cons

One of the main issues, interested in our reader, is still the aspect of reasonability. Why convector, but not an oil radiator for example??What characteristics of power should have a convector electric? How to choose the best one, among the incredible assortment ?

From a certain point of view, any equipment must contain pros and cons, the electric convector is no exception. We will begin by listing the positive qualities, especially since they are many times greater than the minuses of the electric convector.

The main advantage, we believe the technological breakthrough, allowing to design an electric convector with efficiency of 95%. Agree, to pay for electricity and get at the output stink, it would be too much of a luxury. Modern convector converts electric energy into thermal energy with maximum efficiency.

The low price for an average electric convector of 1000 W is a weighty argument in favor of purchase.

Silent operation. The electric convector does without a fan, or any other mechanically. moving constructive elements. Quiet operation is occasionally disturbed by the barely audible click of the temperature sensor, contributing to a more economical operation of the device.

Lack of installation and maintenance work. Electric convector is considered a household appliance, plugged into a 220 volt network and does not require permits from government agencies. The small mass of the convector as an additional plus, in matters of transposition of the device in the heated room

Built-in automatics helps to maintain the desired temperature in the heated room. External temperature sensors made on the type of sockets with a thermostat, additionally provide control over the temperature regime.

The heating element of the electric convector reaches the set temperature in a couple of minutes, starting to heat the room immediately after turning on. The temperature of the element, as a rule, does not exceed 60 °C, not allowing the heating elements to “dry” the air and “burn” the oxygen. The absolute humidity in the room does not change. With the increase of temperature only the relative humidity slightly decreases.

Not a high temperature of heating surfaces, provides a safe environment for people and animals. In addition, you do not have to worry about fire safety.

Declared by a number of manufacturers service life of convectors exceeds 20 years.

Electric convector heating has probably one drawback

So you bought a convector and made sure that your wiring can withstand the extra load. The device included in the network, immediately begins to heat the room. As they say, the electric convector would be of no value, if it were not for one BUT. The only disadvantage, as you can already guess, is the high cost of electricity consumption. But first, as we noted at the beginning of the review, convector heats our apartment only during the off-season, but not during the entire winter period.

Secondly, you should choose convectors for heating with an electric thermostat, then the built-in thermostat will not allow the device to “run the counter” all day long. Thirdly, care should be taken to preserve heat and if possible to reduce its loss, it is necessary to install double-glazed windows, and take care of other elements of insulation.

Another disadvantage. the smell of burning, in fact “burning” is not oxygen, and settled dust on the electric heating element. To remove this defect is easy, or to vacuum the convector, or just to wait for complete combustion of dust.

Instructions for use

The boiler is switched on by simply pressing a button. After that the display will show.

Vaillant boiler cutting off too early

The flashing symbol will indicate low water pressure. After opening the make-up tap, fill the system, referring to the blinking indication. When the pressure reaches the nominal pressure, the indicator stops flickering.

If the pressure drops, there is a leak in the system, which must be found and repaired.

Double pressing the left button of the group “I” will display the current and admissible pressure values, which is very convenient and useful for boiler operation.

The pressure in the boiler rises. Wall mounted two-circuit gas boiler. Repair Part 2

Hello Dear visitors! In the last post on the topic of boilers have been considered the reasons why the pressure in the two-circuit boiler drops or jumps, then it drops, then rises.

Now it is time to clarify the reasons why the pressure in the boiler can constantly grow, or rather grow until the pressure relief valve is triggered.

Given that the principle of operation of most boilers is similar, this malfunction can occur in different models. But, I will tell by the example of a boiler ARISTON CLAS 24 FF because this is the boiler used by me.

The pressure in the boiler increases

When the pressure in the two-circuit gas boiler drops this is still something to understand, but when the pressure rises by itself! What could it be?? However, this is exactly what I once had to deal with. It was found that this is due to safety, relief valve. It began to release pressure by spitting water out of the boiler. Pressure gauge showed a pressure exceeding 3 bar.

The first thing I did was to release the pressure in the heating system through the Mayevsky valve, and began to observe the manometer readings, the pressure slowly but surely grew. My first thought was that the make-up valve was leaking, I tightened it, nothing has changed. Then got the manual for servicing the boiler (Download the manual here) began to examine the scheme of hydraulics, and quickly realized that the cause of the secondary heat exchanger.

So the reasons why the pressure in the boiler can gradually, but constantly grow, are twofold: 1) The make-up tap is not holding. 2) The secondary heat exchanger is defective

Secondary heat exchanger for gas boiler

The fact that the water used for DHW (hot water) is heated by the water used for heating the CO. This is what the secondary heat exchanger is for. It is designed in such a way that inside the hermetic vessel there are two isolated from each other channels for the flow of water. One channel with the heated water and the other with the water that needs to be heated.

The metal plates provide a large contact area between the heated water and the water to be heated. When the partition inside the heat exchanger is damaged (a small fistula appears) the exchange of liquids begins, the water from the water supply system, which needs to be heated, has a higher pressure and begins to squeeze into the channel heated water. That is, it enters the circuit of the heating system, thereby causing an increase in pressure in the system.

How to replace the secondary heat exchanger in a gas boiler

It is elementary to change, at least in the Ariston boiler. You need a socket wrench with a sprocket to remove them. The kit with the new heat exchanger came with four gaskets and two bolts for fixing.

Before removing the old heat exchanger you must shut off all the water supply valves in the boiler, drain the water from the boiler through the drain valve.

Open the boiler, we find in the depths of the secondary heat exchanger and the location of its mounting. two bolts, unscrew the bolts can get stuck, so with some effort. The bolts are here, see the photo below. There are only two bolts. The third photo, a larger view.

Unscrewed, remove, check that the rubber rings (gaskets) did not remain in the joints, they are stuck to them.

Prepare a new heat exchanger, install new gaskets, assemble in the reverse order. Then do not forget: Close the water drain valve, open the water inlet valves and fill the boiler with water through the water make-up valve to the required pressure 1.2.1.5 bar. Never try to ignite the boiler without filling it with water.

Make sure there is nothing leaking. starting.

You can buy the heat exchanger in the store Kotlomir

Addendum: It is not superfluous to expel the air from the boiler after filling it. To do this, turn on the boiler and on the control panel, press the ESC button for over 5 seconds. The purging mode is activated and the pump pumps water for 6 minutes without turning on the burner. Entrapped air will escape through the air vent. You can forcibly turn off the blowing mode by pressing ESC again.

How to turn off the heating on the gas boiler for the summer. step by step instructions

The gas boiler can be shut down in case of an emergency stop, at the end of the heating season, or during commissioning. The procedure depends on the purpose of the shutdown, the type of device and its level of automation. And before taking any actions, it is necessary to get acquainted with the nuances of the procedure.

Gas appliances are an object of high risk. That is why it is necessary to regularly check its working order. This applies to auxiliary equipment, internal elements, utilities (electricity, water, gas).

The main operating element of the gas boiler. the boiler heating system. It is made of metal, exposed to external or internal corrosion. Therefore, equipment manufacturers advise to conserve the boiler when stopping for a long period. This will avoid damage to its elements.

How to do this depends on the fuel used, the material from which the pipes are made, the quality of water. The instructions for preserving the unit are detailed in the unit’s manual.

There are several ways of preservation, each of them has its own particularities.

Preservation method Features
Dry Suitable if the gas boiler must be shut down for a long period of time during the cold season. Water is completely removed from the system. To dry the pipes from the inside, a blower or other external device is used
Wet Suitable when the air temperature does not drop below zero. The unit is filled with water and some caustic agents are added. They create a protective film on the surface of the metal elements
Overpressure method To be used if the gas or electricity supply is cut off. This method maintains the optimum pressure in the system, and the oxygen from the air, which could cause corrosion, does not get inside the boiler. Before using the method of overpressure, the boiler unit is filled with purified water

How to heat water in a double boiler?

In heating mode, the water flowing through the external pipes is heated to the temperature limited by the thermostat. The coolant flows in a small circle inside the boiler, transferring its energy to the water in the inner tubes, the burner is constantly running.

  • Turn off the lower and then the upper tap on the radiator.
  • If you plan to paint the heater, the previous action is enough
  • When it is necessary to replace batteries in the middle of the winter, then before removing each heater bleed pressure through the Mayevsky tap.

How to turn off the boiler?

There are many reasons to manually turn off the boiler. But the main one is the desire to save money on heating. For example, if you go away from home for a while on vacation. But is it worth to temporarily turn off the equipment and how to turn off the boiler in such a case.? We will talk about this below.

Situations when the system still needs to be turned off are many. For example, before repair or maintenance. Or if the boiler is installed at a cottage and there will be no need for heating for a long time. Some owners out of ignorance just pull the plug out of the socket and that’s it. This is wrong. Rules for turning off depend on what kind of automation is installed in the system. Let us consider the most common of them.
