Space Heating Applications
The T-K2 can be used for potable hot water heating applications as well as space heating
applications.
WARNING
• Toxic chemicals used in boiler treatments such as alcohol, glycerol and glycol
group must not be introduced into the system when used for open loop potable
water and space heating.
• The FLASH T-K2 can be used to supply potable water and space heating and
shall not be connected to any heating system or component(s) previously used
with non-potable water where any chemicals were added to the water heating
appliances.
• When the system requires water for space heating at temperatures higher than
required for other uses, a means such as a mixing valve shall be installed to
temper the water for those other uses in order to reduce scald hazard potential.
• Water temperature over 125 °F can cause severe burns instantly or death from
scalds.
• Chemicals such as diluted Glycol can be used for radiant floor, Hydro/fan coil air
or Baseboard heating only.
