Questions on coordination when connecting a gas generator
Gas is already connected. There is a boiler and stove. Consumption of a maximum of 6.6 cubic meters per hour. Counter G6. I chose a generator with a flow rate of 4.9 cubic meters per hour. I turned to the design company and questions began for me. For TU it is necessary to make heat calculation - well done. But I did not understand why.
Question 1. Why do heat calculation for the generator. At the first connection, it was already done. Who is right? But TU received, already good. Made a project, an insert into the existing exit from the ground with a separate meter, cranes, etc. Mosoblgaz wrapped for the reason that the metering station in the house should be one.
Question 2. Is it the incompetence of the designer or the greed of Mosobgaz? The project went up in price. Replacing a pipe counter of a different diameter, etc. The counter in the G10 project is simple without data transfer. Wrapped again - they say it is necessary to put a locking e-mail. a valve that costs 60000r + and a prepaid smart card.
Question 3. Who raves - project. Company or Mosoblgaz? Please clarify the situation. With all respect, Andrew.
Hello. You asked a rather complicated question, which should have been well addressed to Mosoblgaz, but I will try to answer it as far as there is enough knowledge and understanding of the situation. As I understand it, you are arranging a conversion to replace a gas boiler with a new one.

Question 1. As far as I know, the list of documents required for Mosoblgaz to obtain the technical specifications:
1. The statement of the future consumer.
2. Copy of passport.
3. One of the title documents for the object.
4. The situational plan for the location of the object.
5. Permission of the fuel and energy complex of Moscow to use the natural resource.
6. Documents of territorial planning.
In the column RECOMMENDED, I quote literally: "To determine the hourly gas flow rate and the power of the installed gas equipment used to generate electric energy, as well as to service pools, greenhouses, winter gardens, etc., perform a heat engineering calculation". As you can see, heat calculation is advisory in nature. But there is a loophole - you change the project and the organization in the absolute right to recalculate the energy efficiency of the facility.

Question 2. SP 62.13330.2011 Gas distribution systems, clause 7.10: “Each object where gas-using equipment is installed must be equipped with a single gas metering unit in accordance with regulatory legal documents of the Russian Federation».
Do not lie. There can really be only one accounting node.

Question 3. This question has caused me difficulties, since Article 544 of the Civil Code of the Russian Federation states that: "Payment for energy is made for the amount of energy actually accepted by the subscriber in accordance with the energy metering data, unless otherwise provided by law, other legal acts or by agreement of the parties. The procedure for settlements for energy is determined by law, other legal acts or by agreement of the parties».
That is, a prepaid smart system contradicts such a law, since the gas supply will be blocked for the volume of gas that has not yet been accepted.
And here is how they literally try to explain Mosblggaz their demands to consumers:
«The choice of meter is determined by the design decision of the organization performing the gasification project of your apartment building. The installed meters must be entered in the state register of measuring instruments, have a valid certificate confirming the type of measuring instruments with an unexpired verification period. Meters should provide measurement of gas volume in all flow ranges, based on the power of installed gas-using equipment.
GUP MO Mosoblgaz recommends designing and acquiring an OMEGA ETK GSM G-4 gas meter without a smart card manufactured by Gazdevice CJSC. The presence of the GSM radio module allows you to automatically (remotely) transmit the readings of a gas meter. The consumer has the right to pay the cost of gas supplied using the above gas meter without making an advance payment, monthly, until the 10th day of the month following the expired billing month. At the same time, the consumed gas can be paid in any way convenient for you, including by credit card without charging a fee using the “Personal Account” service on the website
».In fact, here they rave, but do not hide, as you can see, that their requirements are RECOMMENDative in nature, and not mandatory. As far as I heard, they can only be obligated to install such meters from July 1, and so far the project is related to MKD and not to private houses. Moreover, the installation there will be carried out during the overhaul and design of engineering systems under construction and not at the expense of consumers (but we will wait / see).
“They say you need to put a shut-off email. a valve that costs 60,000 rubles. ”- I, as a resident of a non-Moscow region, do not understand the cost of 60,000 rubles. Our most expensive one costs about 13 thousand, if you look very well. Okay, we look at the documents, how things are with shut-off valves.
Fire Safety Rules (PPB 01-03): “p. 84. Pipelines supplying gas to household and industrial appliances for its combustion at the facilities commissioned after construction, overhaul, reconstruction and (or) technical re-equipment are to be equipped with heat-sensitive shut-off devices (valves) that automatically shut off the gas the line when the temperature of the environment in the room in case of fire reaches 100 ° C. The indicated devices (valves) must be installed in the room immediately in front of the valve on the gas line.”
And as I recall, one of the SNiPs also regulates something for email. valves.
I advise you to document everything that you are told in words, let all the refusals be justified in writing. So far, I have found only on smarts they have uncertainty. They easily justify everything else.
Please keep us up to date, the question is very interesting.
