Installing a gas boiler in the bathroom

What you need to know when installing a gas boiler in the bathroom

Almost all gas water heaters have the same principle of operation and appearance. The differences between this or that model may lie in their technical characteristics and design. Nowadays, all modern columns can be distinguished by four main features.

  • The flow capacity (or power) allows you to determine how much water the device heats in a certain period of time. Today you can find models on the market with a flow capacity ranging from 6 to 18 liters. You should not buy more powerful speakers in the bathroom, as units with a capacity of 18 liters for domestic purposes is inappropriate. For a family of 4 people is quite enough speaker with a capacity of about 12 liters.
  • The gas burner affects the economics of the unit and ease of operation. There are three types of burners used in gas heaters: constant or variable capacity, and modulating burners. Bathroom speaker with a constant-power burner is able to independently adjust the flame depending on how much water pressure is flowing through the device. In columns with variable capacity burners it is necessary to adjust the flame manually, but after a single adjustment the automation will maintain the selected temperature by itself. The most advanced. modulating burners allow to obtain water at a stable temperature at the output, regardless of variations and changes in the input.
  • Ignition. can be manual (piezo ignition) or electric (working with batteries). expensive and modern models are equipped with an electric ignition, working from the electrical network of the apartment.
  • The number of functions. not only the price of the device depends on them, but also the reliability and safety, since most of the additional functions allow you to protect the occupants from gas leaks and regulate the pressure of water in the system and gas in the gas line.

SNiP regulating the installation and to them

To determine the question, “Can I install a gas boiler in the bathroom”, it is necessary to understand what normative document regulates this issue. Usually, in the next SNiP, directly stipulated all the requirements and nuances of the location and rules for connecting heating equipment. But, regarding the installation of a boiler in the bathroom, not everything is so simple:

  • The fact that it is prohibited to install a gas boiler in bathrooms and toilets, is specified in the document SNiP 2.04.08-87. The document expressly prohibits the installation of heating equipment in these areas.
  • At present, the above document was canceled: The Decree of the State Construction Committee of December 23, 2002, the. In Building Regulations No. 163 these building codes have been deemed ineffective in the territory since July 1, 2003. To replace these SNiPs, the above Ordinance enacted SP 62.13330 (SNiP 42-01-2002) “Gas Distribution Systems.
  • The above SP does not raise the question of whether or not a gas boiler can be installed in a bathroom or toilet.

As for the basic requirements regarding the installation of gas heating equipment, they should be as follows:

  • The total area is not less than 9 m², for atmospheric type boilers (gas burner open type) and 8 m², for models with a closed burner.
  • The presence of supply and exhaust ventilation.
  • Window with a vent. the size is calculated, depending on the capacity of the boiler equipment. For residential buildings, it is usually sufficient that the window opening does not exceed 1.7 m².
  • The door should not adjoin to the box hermetically. A 1-2 cm gap is left at the bottom. As an option, from below, the ventilation grille is cut into the door leaf.
  • A distance of at least 1 m to the adjoining wall up to the boiler.

Proceeding from the above requirements, it is forbidden to install a gas boiler in a standard toilet, at least due to the lack of space in the room and the lack of natural light.

In the bathroom, installation is not allowed mainly for the following reasons:

  • Application of older regulations. SNiP 2.04.08-87 was abolished long ago, in practice, but DO still remain a “cornerstone” of the gas industry.
  • Increased humidity in the room, which leads to accelerated corrosion of the internal components of the boiler and failure of electronic automation.
  • Over draught due to the mixture of air vapours and combustion gases.

These are the official reasons why you can not install the boiler. These are the arguments you may hear from gasmen when they ask you to hang gas equipment in the bathroom.

If you are wondering whether you can install a gas boiler in the bathroom or toilet, you need to consider the following requirements:

  • Remodeling the room and making changes to the technical documentation. When the gas service does not provide registration of the appropriate heating equipment, you can try to change the status of the premises. “Turning” the bathroom into a closet or utility room and filing the appropriate application to the Technical Inventory Bureau will immediately help solve the problem. If the technical passport of the house or apartment will indicate the appropriate types of premises, refusal on the part of state authorities will not follow. However, the presence of plumbing devices can entail a ban on the installation of the heating boiler. If the room has only the installation of a toilet, changing the plan will not cause problems.
  • Connecting the new gas equipment. Provided that the design of the room mentions registered heating equipment, there will be no problems with the installation of a new boiler. It is much easier to replace an old device with a new one, if you already have permission for such devices.

Masters from the gas service in some regions of our country may agree to install certain water heating systems in sanitary rooms. These should be special devices with a closed combustion chamber. Before choosing and installing such equipment, it is necessary to consult with gas specialists.

What requirements must a bathroom meet?

It is important to understand that not every bathroom is suitable for mounting a gas boiler. For example, standard bathrooms in conventional Khrushchev or 9-storey buildings built in the 70-80s are too small and have insufficient ventilation. To make sense to at least consider installing a gas boiler in the bathroom, it must meet certain requirements:

  • total floor area of at least 7.5 m²;
  • The presence of a functioning ventilation system;
  • there must be a window of at least 0.25 m²;
  • Height of ceilings not lower than 2 m;
  • When the door is closed there should be a gap of 1-2 cm between the door and the floor;
  • There must not be anything in front of the machine within 1 meter;
  • The walls of the bathroom must be made of non-combustible materials.

Thus, from the above requirements, it is clear that the owners of apartments in multi-storey buildings are practically deprived of the possibility of installing a gas boiler in the bathroom. Owners of private homes have more chances, because they can initially build a bathroom that meets all of these standards.

In order to assess the possibility of equipping the bathroom with a gas boiler, it is worth, among other things, to study all the positive aspects of this project. In a private home, especially if the redevelopment of the premises is carried out, the problem of placement of new equipment is always very acute. That is why the option of using the co-location in the bathroom heating boiler and bath is quite ambitious and has several advantages:

  • Significantly saves space inside the house;
  • The number of pipes is reduced;
  • Hot water to the bath comes faster, there is no great loss of temperature;
  • In the rest of the room there is no noise from the working equipment;
  • There will be a window in the bathroom.

On the other hand, with this layout also has a number of disadvantages, which must be taken into account:

Types of water heating equipment for the bath

Today the range of devices for heating water is very wide and varied. The choice of suitable equipment for domestic needs depends on how many liters of water per day each family member requires. In addition, when purchasing a water heater, it is necessary to consider such indicators:

  • Source of energy
  • The place where the unit will be installed. For small apartments, it is desirable to choose compact water heaters.
  • Safety.
  • Source of energy consumption.
  • The amount of gas or electricity consumed.

While the installation of gas-fired units in the bathroom can be problematic, the installation of water heating equipment in these parts of the house is allowed. That is why most apartment owners use storage tanks for heating water, which, in addition, provide heating in the bathroom.

Currently, the most common water heaters are:

  • Accumulation units for heating water.
  • Flow-through water heaters.
  • Single-circuit and double-circuit boilers.
  • Thermostatic mixing water heater.
