Abstract

With the installation of heating systems in churches over the last century an increase in damage and decay of valuable interior decoration can be observed. Research has shown the connection between indoor climate and degradation. A study in South Tyrol (Italy) analyzed the effects of different kinds of heating systems on the indoor climate, recording air temperatures and humidity with 12-25 sensors in 25 churches over a period of 4 to 8 weeks. The resulting characteristic temporal and spatial heat as well as humidity distribution, were used to estimate risks and benefits. Hot air heating with short heating sessions showed up to be the most harmful, whereas other studied heating systems demonstrate specific strengths and weaknesses. The most frequently used heating system in South Tyrolean churches is hot air heating. However, temporal and spatial heat and humidity distribution and their potential impact vary considerably. Therefore it is analyzed the influence of operation mode and time, outlet position, temperature of heating air and utilization frequency, on characteristic parameters describing the heating system’s performance.
