Use of Natural Gas

Central heating system in the block of flats

Assuming the condominium has a central boiler-burner, with or without an autonomous heating system for each apartment, the conversion to gas heating is simple. The oil burner is replaced by a gas burner, without necessarily involving a change of boiler, and the gas supply meter is connected to the burner by piping.

No substantial intervention in the building means you can have gas heating quickly, easily and economically installed at home. You don’t need to change the heating water pipes, radiators or anything else from the central heating installation.

In addition, with natural water heating you can also have hot water in the apartments as long as you hook each apartment up to a boiler for hot water use.

Autonomous Heating in a detached house or only in your apartment

It is possible to use an individual boiler with an integrated gas burner if you have a detached house or if you only want gas for your own apartment. The individual boiler has very small dimensions and weight and is usually mounted on the wall in a semi-outdoor area (e.g., balcony) or in the interior of the apartment (e.g. kitchen or bathroom).

Hot water

Natural gas enables you to always have plenty of hot water, instantly whenever you need it without preheating, as the boiler is connected directly to your apartment’s hot water circuit and works immediately when you turn on the tap.

The water is heated at the same time you turn on the tap and only as much as you need, without wasting energy. With natural gas you have total comfort and economy compared to electricity!

Cooking

Cooking tastier, faster and more economical.

Kitchen and gas work together. All famous chefs cook only with gas and that’s no coincidence. All famous chefs cook only with gas and that’s no coincidence. Cooking with gas makes all your favorite recipes more delicious, since you have complete control over the intensity of the energy that bakes, boils or fries every single moment. The hobs don’t need to be preheated and the speed of cooking is impressive. The difference in economy over electricity is great, and the difference in the deliciousness of the food is up to 100%.

Air conditioning

Natural gas enables you to cover your cooling and heating requirements with the same device.

A central air conditioning unit is placed outdoors and supplies cooling or heating to the internal units on your premises. An environmental solution that offers economy of operation. Mainly offered for new installations or premises under renovation.

Autonomous Heating in a detached house or only in your apartment

The gas is supplied by an external pipe that starts at the gas meter and ends at the installed individual boiler. The boiler is connected to the heating water circuit of the installed radiators as well as to the hot water circuit of the apartment. Thus, the hot water (heating and domestic hot water) circulates exclusively in the water circuits of the apartment. If you have a detached house, no changes to the water pipes and radiators are required, although in some cases of apartments it is possible that interventions in the water pipes may be required.

In case of independent heating, you additionally reap the benefits:

Total heating independence: possessing an individual and not a communal heating installation, you enjoy 100% autonomy of heating and use gas based solely on your personal needs and capabilities, without depending on others.

Convenience and comfort: Operating your individual gas boiler is simple and easy with just the push of a button.
Consumption control and accurate measurement: Check your consumption every time you pay exactly what you have consumed based on the meter reading corresponding to your apartment.

In addition to continuous and economical heating, with the individual gas boiler you can also meet your hot water needs as the boiler is connected to the hot water circuit of your apartment.

Heating

You can use natural gas to generate heat for your business, both internally and externally.

The heating of the indoor area can be conducted:

Heating can be accomplished by using the existing boiler or by replacing it, as well as by substituting the burner
Replacement or substitution of the existing gas boiler, or replacement of the existing boiler, with the use of a wall-mounted gas boiler (conventional or condensing) with an integrated burner.
Natural gas fired boilers (self-contained gas-fired appliances that produce hot air, while the flue gases are exhausted by a horizontal flue to the exterior – without a chimney)
Gas fired air boiler – air ducts (air heating is combined with ventilation of the room)

Cooking – Baking

Natural gas makes cooking/baking tastier, faster and more economical.

Depending on your specific professional needs, there are gas-fired appliances for all types and methods of cooking and baking. In particular you can operate: ovens (cyclo-thermal, tubular, air-heated), hobs, fryers, grills, broilers, griddles, platters, chickens, rounds, salamanders, cream kettles, crepe pots, frying pans (donuts/spaghetti), doners, baking grills, etc.

If your equipment is operated with an oil burner, only a change of the burner with the gas burner is required. Gas appliances have a cost equivalent to electric appliances. In case

you have CE marked appliances that operate with LPG, only the injectors of the appliance need to be changed to natural gas.

Cooking or baking with gas makes all your favorite recipes and creations more delicious, as you have complete control over the intensity of the energy used for baking, boiling or frying at all times. The hobs do not need to be preheated and the speed in cooking is impressive.

Hot Water

With natural gas you can meet any business premises’ hot water needs and always have plenty of hot water, instantly and whenever you want it, without the need for preheating.

With a gas boiler of the appropriate technology, for each case depending on the needs of your business premises (boiler, storage water heater or a combination of these in the same device), you have instant hot water with the opening of the tap, covering the amount you require without wasting energy.

Hot water boilers (or instantaneous water heaters or instantaneous heaters) for the production of domestic hot water are continuous-flow devices, have small dimensions and do not have a hot water storage tank. Their function starts as soon as there is a need for hot water, and therefore the appliance must have an appropriate power output to meet the consumer’s requirements. A range of newer instantaneous water heaters with a greater capacity for instantaneous hot water production, focusing on temperature and its stability throughout the consumption, is also available in this category.

Condensing appliances are another option in the category of instantaneous water heaters. These models have an efficiency greater than 90%, a significant reduction in gas consumption compared to the corresponding conventional appliance, thus achieving additional savings.

Storage water heaters are floor-mounted devices and have the ability to store hot water. Large quantities of water can be heated and stored using this technology, but the standby mode leads to energy losses. Their feature is that there is no need to run the heating source at the time the hot water is used.

In some cases, a combination of both is necessary and is covered by appliances which either have a boiler integrated with a hot water storage tank or by two separate appliances which are suitably connected to each other.

Special Professional Uses

Natural gas is a versatile energy source that can be used in many important commercial applications, meeting your energy needs and providing significant savings and comfort.

Washing – Drying – Ironing (steam production)

With gas you wash, dry and iron more economically.

Gas-fired appliances are available for all required tasks. In particular, there are washing machines, dryers, dry-cleaning machines, ironing presses, ironing cabins, cylinder ironers, etc.

As long as some of the appliances are powered by a steam generator or steam boiler, you can use the existing steam boiler or steam generator and simply replace the oil-fired drive burner with a gas burner. In particular, if you have appliances that operate with a built-in gas burner (e.g. dryer, roller irons), converting to gas only requires a change in the appliance injectors.

Dyeing – Baking

Natural gas makes dyeing and baking more economical and efficient.

Dyeing and baking work is conducted in gas-fired dyeing and baking chambers. Dyeing and baking work is conducted in gas-fired dyeing and baking chambers. There are 2 technologies in particular: the conventional technology of indirect combustion using an air boiler and the technology of direct combustion, which works only with gaseous fuel and achieves energy savings of 30% compared to the technology of indirect combustion.

Gas chambers have a cost equivalent to diesel combustion chambers of the same technology (indirect firing) assuming you are interested in a new installation. However, current installations, i.e. chambers with an oil burner, require a change of the burner with the equivalent gas burner as well as some changes with the existing control panel.

Paint booths are faster in their operation resulting in higher productivity for your business (more car paintings per day). Savings are also achieved on electricity as the air supply motor runs for a shorter period of time.

Casting – Processing – Bonding

Natural gas melts and processes metals more economically and efficiently.

Cogeneration is the simultaneous production of exploitable or usable electricity and thermal energy from the same energy source. In order to operate the torches, oxygen is also required, and its installation is also simple.

Casting with gas is slower and helps in its quality as no part of the mixture is destroyed.

Air conditioning

With natural gas you can achieve a complete solution for the air conditioning of your premises, i.e. COOLING in summer and HEATING in winter. You have a device for 2 uses, heating and cooling. Several appliances also produce hot water for domestic use. Several appliances also produce hot water for domestic use.

Requires a central air conditioning unit (gas-fired heat pump or absorption unit) mounted externally and domestic units (water fan coils or dedicated freon units) powered by the central unit.

Co-production

Cogeneration is the simultaneous production of exploitable or usable electricity and thermal energy from the same energy source.

A wide range of technologies can be used for CHP. All CHP systems always include a power generation equipment and a heat recovery system. The technologies that can be used in the commercial and small industrial sector are mainly:

internal combustion engines
micro turbines
fuel cells

There is also the possibility of tri-generation with simultaneous production of electrical, thermal and cooling energy (through an absorption chiller).

The gas cogeneration system is a very good proposal for your business premises, as long as your needs are covered by the heat load produced, providing economy of operation, environmental benefit and possible independence from the electricity distribution network.

Coverage of thermal needs in crafts – industries

Natural gas finds specialized uses in industrial/manufacturing sectors with direct thermal needs such as foundries, drying plants, etc.

However, in most industries, where thermal needs are met indirectly with a fluid (steam, heating oil, hot water), the substitution of other fuels by gas is very simple and is carried out by using the existing boiler/generator or replacing it and simultaneously substituting the burner.
