Frequently asked questions

Question 1: What is common in the two similar sound companies (Altherm Ltd. - Alternconsult Ltd.)?

Similarity is a coincidence

Altherm Ltd. produces, installs and upgrades biomass  (bale burning, chips and pellets firing) heating systems owned by Mr. József Sarusi-Kiss and Mrs. Andrea Sarusi-Molnár  as well as a danish companion under a danish license.

Alternconsult Ltd. is the family business of Mr. József Sarusi-Kiss and Mrs. Andrea Sarusi-Molnár offering innovative solutions in several areas. Connecting to renewable energy solutions it performs the complete design for the installation of biomass boilers and helps the customer in the licensing process as well.

Additionally, designing and constructing of agricultural storages and technological buildings such as bales, crop and machinery storage, sheep, cattle, goat and poultry barns.
 
The bended (IVLMS) structures are easy to modify, fast to build, helpful to finish agricultural investments with great flexibility and low budget as well as a short payback time. Insulated hen houses have exceptional metrics of energy, especially if heating is done by the bale and chip firing systems of Altherm Ltd. (www.altherm.hu).

Question 2: What is the difference between the two companies?

Alternconsult Ltd. only plans and permits biomass-based (bale firing, chip and pellet firing) energy systems while Altherm Ltd. manufactures and installs them which indludes local pipelines and internal heating systems as well.


Questions related to Biomass heating:

Question 3: What kind of licenses are needed to use biomass (bale burning, chip and pellet firing) systems?

Pre-construction permit from the local building authority or the MKEH permit for over 500 kW.

Question 4: Do biomass (bale firing, chips and pellet firing) systems needs to be designed?

Yes. Designing biomass fired systems requires special knowledge, experience and references. The content of the package includes the architect design and the static and the engineering plan (biomass heating, control, regulation, chimney dimensioning, internal heating system plan), fire and safety chapter, environmental design, lightning and contact protection.

Question 5: Is it true that for biomass boilers and heating systems over the 3 hectares should be subjected to environmental impact assessments?

Not true. In case of any construction on real estate above 3 ha, permission is required, the impact assessment is mandatory, so this does not apply only to biomass boilers or biomass heating systems.

Question 6: What should be considered when using the biomass boiler for alternative energy heating systems at the stage of investment preparation? 
The cornerstones of planning biomass boilers, heating plants (bale firing, chips and pellets):

- accurate assessment of performance requirements
- assessment of local biomass accessibility:
- continuous supply of straw, rapeseed, maize, soy or pedestrian bale for bale firing
- keeping the straw, rape, corn, soy or pedestrian bale dry under a bale wool fabric (www.altherm.hu) or under the multi-purpose
   IVLMS buildings that are ideally suited for this purpose,
- distance of transport within 40-50 km
- determination of the type and performance of the biomass boiler
- deciding whether a central biomass heating plant with a local pipeline (Uponor) or individual biomass heating for each building
- preliminary financial calculation of the biomass heating and its return time, decision

Question 7: How long it takes designing, manufacturing and installing biomass systems?

Evaluation of bale and chip milling systems, preliminary calculations and compilation of tenders take generally 2-3 weeks. Planning and licensing for a typically technical biomass heating plant is usually about two months. The production of biomass boilers usually takes between 30-60 days after a signed contract, construction of barns and heating pipeline, interior heating works between 2 to 4 weeks. Some of the works can be carried out simultaneously. Implementation of a medium-sized (300-600 kW) biomass heating plant takes about 3-4 months in total after the design contract has been concluded.

Question 8: Is there any specialty in design and authorization of biomass heating plants?

Yes. The biomass boiler requires a separate chimney. If the existing chimney is not suitable for connection and it requires a chimney of more than 6 meter a building permit is necessary for connection of the boiler. Chimney scaling is moreover, a critical element of biomass firing which many investors are ignoring. Constructions between 50 and 490 kw power needs permit of the building authority, above 500 kW power permit of the MKEH is required. Above 140 kW the combustion is a source of pollutant for biomass boilers so it is subject to authorization and is required to provide data. Overall, the designing, manufacturing, licensing and installing biomass firing systems requires special technical expertise.

Question 9: Why is it worth investing in a biomass heating plant (straw, rape, corn, soybean or baby bale, chips, pellets)?

The savings of biomass firing compared to natural gas and its payback time are very interesting for a smart investor having available or easily accessible biomass raw material.

The level of savings ranges between 80% and 90% even with purchased strawbales.
By using a good quality wood chips about 50-60%, by agripellet 30-50% (quality and moisture content is vital), 20-25% using wood pellets.

The payback period of strawbale burners are about 1.5 to 5 years. Very good for heat demanded poultry broilers such as turkeys, ducks, geese, sows and piglets and processing plants eg. slaughterhouses, meat processing, dairies, cheese factories, etc. needing hot-water all year long.

The payback period of chopping boilers is about 3-8 years, for wood pellet systems 6-10 years.

Occasionally, high savings can be achieved when combusting agricultural by-products such as sunflower shell, grain leftovers, sour cherry seeds, rice husk, etc. In these cases the investor should only think of special boilers.
 

Questions concerning agricultural storage buildings:

Question 10: What is the fundamental difference between sheep, cattle and goats or broiler barns?

Sheep, goat and cow barns usually do not have to be insulated might only the roof structure, while poultry houses require modern and precise heat insulation as energy costs such as heating, ventilation, electricity are one of the most important costs of poultry technologies. Thus, sheep, goat and cattle buildings have no architectural boundaries. Might be side walled or single-layered, ventilated throughout, sometimes with curtain-like space separation. Ventilation can be natural, manual or mechanical. In contrast, the side walls and roofs of modern poultry houses are energetically calculated and designed in a thermally insulated way, ventilation is generally automated in high-level .

Question 11: What does the IVLMS means shown on the Alternconsult brochures and web site?

IVLMS is indeed an acronym. IVLMS = bended frame structure. It summarizes the most important feature of the systems designed and distributed by the company. The most important feature of the system is that the roof structure can be constructed quickly and easily from bended elements. The IVLMS system appears in bale, crop, machine storage and in sheep, cattle, cow, pig and broiler nurseries as well.

Question 12: What makes the IVLMS systems preferable and why should an investor choosing it?

Good for any storage (bale, machine, crop storage) or animal farming (poultry, sheep, cattle, goat, sow, pig) with its certain span and height options. Where applicable the structrure can be built very quickly with low budget so it is an excellent investment. In certain areas of apllication it is not subject of building permits.

Question 13: What cover can be on IVLMS systems?

The cheapest solution is the PVC cover with 10 year warranty, 15-20 years of life expectancy with proper handling and its compatible heat insulation. Side panels and ceiling made out of sandwich panels, roof made with two layers (2x80 mm) of rolled fiberglass.

Alternatively, an expanded polyurethane foam or a tested heat-insulating material can be included.

Question 14: Could IVLMS structures be covered with other materials as well?

Yes, although the pricing and lifetime of the PVC cover is outstanding IVLMS strutcures can be covered with galvanized, aluminum or steel trapezoidal sheets supplied with auxiliary bended or rolled elements with illumination to the particular trapezoidal profile.

The system also includes fully or partially retractable folding curtains, doors, and interlocking structures. These products are unique such as their pricing.

Question 15: What is the lead time for designing, manufacturing and installing IVLMS farm storages and livestock buildings?

The survey, the preliminary calculations and compilation tenders of IVLMS agricultural and livestock structures take usually 2-3 weeks. Planning and licensing of an average complexity is usually about two months. The production of structures, covers and the thermal insulation is generally about 30 to 60 days after the signed contract. The installation is between 3 to 6 weeks which is increased by 4-6 weeks for internal education of biomass heating technology. The average execution time of a medium-sized building is 3-6 months from the conclusion of the design contract depending on the complexity of the building.

Question 16: What are the other technological benefits of biomass heating in poultry farming?

Using Biomass heating will put gas-burning devices being a spare, operation of thermo fans are recommended instead.
The disappearance of gas burning offers many advantages to the investor beyond drastic heating cost savings:

- No gas combustion smoke produced inside
- The operation of thermo fans does not reduce the oxygen content of the air in the barn
- No significant arising of vapors will appear in the barn
- Thanks to this requirement of ventilation is lowered by 50% at least
- Due to the decreasing ventilation requirement the need for heating is also significantly reduced
