Make yourself independent of oil price increases and fossil fuels:

Fully Automatic Stoker Boiler With Hopper The HS-TARM Multi-Heat boiler is especially well suited for effective and environmentally friendly firing with biomass such as wood pellets and corn.

Significant savings on your heat bills The HS-TARM Multi-Heat boiler is a great choice for sustainable energy heating of homes and light industrial, commercial, and institutional buildings. Firing with wood pellets or corn in the MultiHeat can achieve considerable savings in comparison to fossil fuels. Such savings depend, among other things, on the type of fuel, purchase prices and the annual efficiency of the old boiler. Furthermore, many local governments, possibly yours, are giving grants or subsidies for the installation of Multi-Heat boilers using renewable energy fuel.

Construction and function The construction of the boiler gives high

operational security, significant durability, excellent economy, environmentally friendly combustion and simple operation. Depending on the heating requirement, the feeder mechanism automatically feeds the appropriate quantity of fuel into the combustion chamber. The built-in blower produces a precise mixture of primary and secondary air, resulting in a very high efficiency. The temperature is regulated by a two-step control. This means that the boiler operates at full output until the set temperature is close to being achieved. Then the control switches over to reduced output and continues at this rate. If the boiler temperature drops slightly below the set temperature again, the control will once again switch over to full output. This control ensures constant heat. For best efficiency, the boiler size and adjustment of the output ought to be only slightly greater than the buildings requirement.

The hopper must typically be filled up once or twice a week during cold weather. However this will depend on the heat requirement, hopper size and fuel. The possibility of automatic feeding of fuel from a large external bin or silo is also available. Ash is removed as required.

A heat storage tank is unnecessary The boiler output can be regulated from 100% down to 30% during continuous operation and, in pilot/standby mode, as low as approx. 3412 BTU/hr (1 KW). In order to maintain the boiler outside the heating season, at least one hot water tank 25-80 gal. as well as 1-2 radiators or under-floor heating must be connected (open), but as such no large heat storage tank is necessary. In order to obtain the best possible yield as far as the firing economy, the environment and comfort is concerned, it is important that the boiler is correctly installed and adjusted.

About the Manufacturer HS-TARM Multi-Heat boilers are manufactured by BAXI/AS. BAXI A/S has grown to be Denmark’s leading producer of central heating systems used to supply the space heating and domestic hot water needs of private dwellings. The production of BAXI A/S products is based on strict requirements for material and technical construction design. The

•

For economical, environmentally friendly combustion of fuels such as wood pellets and corn. Constant heating gives optimum building comfort. Very high efficiency, up to 89-91%. Multifunctional digital control provides simple operation with continuously variable heat output from 30-100%. The boiler does not require a heat storage tank. Exposed parts of the combustion chamber are constructed in acid-proof, stainless steel (AISI 316L). Remaining steel plates exposed to flue gas are • inch thick. Automatic shut-off to prevent fuel hopper burn back. Delivered completely assembled and ready - mounted with hopper, casing and control. Automated refilling of hopper available as optional extra.

Multi-Heat boilers have been tested and certified by safety, air quality, and consumer organizations for use in Europe, the USA, and Canada. It has always been a part of the company’s objective that the products from BAXI A/S should satisfy the users requirements regarding both the functional quality and good taste. Currently, BAXI A/S carries out quality control in accordance with DS/ENISO-9001, which is an extensive, internationally recognized

standard for quality control systems. Reliability of operation, unique firing economy and, not least, consideration of the environment are factors which have been instrumental in placing BAXI A/S as an internationally recognized supplier of central heating boilers. To maintain its leadership position, BAXI A/S constantly looks to develop and improve its products. There is never a compromise of principle, solid quality, high output or timeless design.
