This brand is from ONMETAL and is made in Turkey. The RS SERIES offers three pass cast iron boilers with automatic electronic controls. They are available in eleven sizes to match the heating needs of virtually any home but their website does not have a stated warranty policy. 


These boilers are made in Germany and are sold throughout Europe.

The A1 (shown here) is available in four sizes and features stainless steel construction for durability. It has a built-in programmable digital control and an inverter drive pump as well as the ability to burn a blend of fuel oil and bio-oil.

Rotex is a part of the DAIKIN GROUP and the units are backed by a very good guarantee. 


This brand is from the SIME GROUP and is made in Italy. The ESTELLE HE is a high efficiency floor standing boiler that is made of cast iron for durability while the RONDO models are basic boilers. Their website is not much help and does not have a stated warranty policy.


The INTREPID SERIES of units are available for steam or hot water and for direct vent applications. The EUTECTIC EC 10 units are three pass units that are more resistant to thermal shock. They are compact units that are direct vented and have a hinged burner door for easy cleaning. They are very quiet for an oil fired unit but the warranty on the units is not very good when compared to other brands. The XL 2000 is a basic boiler that is designed for those that are more cost conscious.


These units are three pass, cast iron units with an AFUE of up to 87%. They can be direct vented and have a swing open burner door for ease of maintenance. The brand is from BOYERTOWN FURNACE COMPANY and is only available through a limited dealer network that is mostly in the eastern part of the USA.
