Here is the code - decoded
1) "DWELLING UNIT" means one or more rooms located within a building and used or intended to be used for human habitation by one or more persons with cooking, eating, living and sleeping facilities and with separate sanitary facilities.
2) "STOREY" means that portion of a building which is situated between the top of any floor and the top of the next floor above it, and if there is no floor above it, that portion between the top of such floor and the ceiling above it.
ThermoDrain & The Manitoba Code
- A ThermoDrain drain water heat recovery device must be installed on a shower in a residential dwelling such as a home, condominium or apartment.
- If more than one shower is in the home, at least one shower must be hooked to the ThermoDrain
- The ThermoDrain must be at least 42% efficient. The efficiency must be CSA B55.1 certified and the unit must be safety certified to CSA B55.2. ThermoDrain has both these certifications. The model used to meet the code requirement is the TD342B.
- The ThermoDrain must have the cold water hooked to the bottom of the unit.
- Preheated water from the ThermoDrain can be installed in 3 different ways.
a) Preheated water is sent to the inlet of the hot water tank,
b) Preheated water is sent to the cold outlet of the shower
or c) Both a) and b)
- Drain water heat recovery is not required where there is no stories beneath the shower in the home.
- For complex installations such as condos, apartments where a drain stack is shared with several dwellings, the MURBS guide will help determine how to install this technology and meet the code requirements.
