"How Hot Should The Water Be?"
Refer to
On a building fitted with a temperature limiting device such as a tempering valve and where an 874 series
water heater is installed without a separate untempered hot water line to the kitchen, laundry or other non-
ablution area, although the Kitchen controller will be able to display temperatures above 50°C and the water
leaving the water heater will be at the set temperature, the maximum water temperature which can be delivered
to the hot water outlets in these locations is determined by the temperature setting of the temperature limiting
device. This is usually 50°C.
On a building fitted with a temperature limiting device set to 50°C, to enable the delivery of water temperatures
above 50°C to the kitchen, laundry or other non-ablution area, separate untempered pipe work must be
installed from the water heater to the hot water outlets in these locations.
