The City of Ottawa has a nice new web page that acknowledges the existence of solar energy, and in particular solar domestic hot water (SDHW). The site, which can be found on ottawa.ca gives information about two different types of SDHW systems: a CSA approved factory packaged system and not factory packaged system. Both types of installation need a building permit.
Both installation types must be installed by a qualified installer (CanSIA certified) but non-factory packaged installations must be certified compliant with CSA F379.1-09 (the reference standard for SDHW) and with the Ontario Building Code by a professional engineer licensed in the Province of Ontario.
This doesn’t sound like a lot of help, but when I had my solar system installed, there were no guidelines or standards available and we had to slog through a morass of bureaucracy to get our installation approved, so that guidance is very welcome.
This information should make the process of installing SDHW more transparent and it should really reduce some of the risks to the homeowners and installers. Good job Ottawa!
