Sentence 9.33.4.2.(1)

Intent 1:

To limit the probability that the installation of hydronic heating systems will fall significantly below expectations, which could lead to inadequate performance or premature failure, which could lead to an inability to maintain adequate indoor air temperatures, which could lead to condensation.

This is to limit the probability of:

• the inadequate control of relative humidity,
• the generation of pollutants from:
  • harmful micro-organisms and the media they grow on,
  • biological growth, or
  • materials that become unstable on wetting, or
• the deterioration of building elements.

This is to limit the probability of:

• negative effects on the air quality of indoor spaces, and
• the inadequate thermal comfort of persons.

This is to limit the probability of harm to persons.
