In the last years a lot of activities have been conducted to raise the awareness of cleaner BB. Even if a lot of old installations have been updated or exchanged, still too much installations are old or inefficiently used. What can we do to motivate by incentives the replacement and explain the correct use of bb-heating installations by empowering BB-experts along the value chain? This Challenge is part of the Interreg-Alpine Space project BB-CLEAN: Strategic tools towards a sustainable use of biomass for low carbon domestic heating. It is dedicated to an exclusive expert crowd of BB-Experts in the Alpine Region.

Question:

What incentives and tools can be used to optimize or replace old BB-heating installations?

Background:

High emission levels are often due to low quality fuels or poor user behaviour. Heating material of insufficient quality, with too high humidity is used and the fuel is not stored appropriately. In the case of individual firing systems, ignition is particularly susceptible to errors. The highest emission values occur in this phase.

Further the main problem is the old stock. These furnaces are hardly ever replaced, as long as they are not broken, which is hardly the case due to their long life expectancy. Many people shy away from switching to new technologies for fear of not being able to use it.The old stocks of biomass boilers and second stoves are a major problem. They produce very large quantities of emissions. Especially second stoves will work forever, because they are hardly used. Manually refillable plants always carry the risk of being operated incorrectly and misused as waste incinerators. From garden fences to pallets and newsprint, everything that burns will be burned.

Inadequate maintenance, problems with the chimney and inadequate temperature levels during combustion also cause increased emissions.

If modern plants have increased emission values, this is mostly due to the secondary side and problems with the hydraulics. This problem occurs if the new biomass plant replaces a previously used oil or gas boiler. In comparison, biomass appliances have slower reaction times and lead to significantly higher emission values when they are constantly switched on and off. A missing or poorly dimensioned buffer also increases emissions.

If retrofitted, it is also possible that the boiler and the heating system do not match.

Your Ideas/Answers:

 

We are looking for ideas and your experiences in the following two fields of actions:

 

1) (Financial) Incentive schemes

2) Role of BB-Experts along the value chain (e.g. chimney sweeper, fuel provider, craftsmen) in this context

3) Further tools and platforms to support the optimization

The ideas could be of various detailness from just short thoughts/experiences to larger concepts.
