Natural Gas Boilers
KEA SA having developed expertise in gas heating has chosen to work with the world's two leading natural gas boiler companies.

► ARISTON

► RIELLO

The choice of the two companies in question was made with the sole consideration of providing you with the best possible and comprehensive service, always with the aim of investing in an installation that will last over time.

Both ARISTON and RIELLO have their own technical service departments based in Thessaloniki, which means that access to spare materials and know-how is immediate, giving us the opportunity to serve you quickly.

Gas boilers are now all condensing and are divided into two main categories:

1. Indoor (for installation inside the house or boiler room)
2. Outdoor (for installation on the balcony)

Oil Boilers
Oil is expensive as a fuel and for this reason it requires:

– Correct installation
– Correct choice of boiler
– Correct setting by qualified personnel

There are two main categories of boilers:

• Conventional, which are only allowed to replace an old boiler according to the legislation and are an economical solution for purchasing a machine.

• Condensing, are the new generation oil boilers, which take full advantage of the exhaust gas temperature and save us about 40 % of fuel compared to conventional ones.

• Individual Thermostahl GT20 oil unit

• Thermostahl GT30 individual oil unit

•Individual Thermostahl GT40 oil unit

• Firebird oil condensing boiler 20,000 calories

• Firebird oil condensing boiler 30,000 calories

PELLET boilers
Pellet stoves are state-of-the-art technology devices, which at the same time ensure very high performance, heating autonomy and reduced pollutants. Fuel consumption is at very low levels, which makes Pellet stoves an ideal choice for heating the entire house. Savings start at 40% and can go up to 60% compared to oil.

Advantages of using pellets

1. The pellet is practical to use, since it is easily transported packed in a practical package.
2. It provides high comfort, since our pellet-burning devices allow thin
3. It has stable quality and characteristics compared to wood and other cheap fuels.
4. It is efficient in combustion, since pellet boilers, unlike wood boilers, have automations to regulate combustion
5. It is ecological, since it allows us to use forest residues and other materials that would otherwise not be used.
6. It is economical to use.
7. Its price does not show large fluctuations as it happens with other fuels (oil, natural gas, electricity, etc.)

Wood boiler
Advantages of biomass boilers

1. Biomass is considered a renewable energy source because what is cut can be replanted
2. Domestic production is possible
3. Lower consumption costs than oil and natural gas (influenced by boiler and fuel efficiency)
4. Relatively low operating costs (depending on the type)
