- 52°C has been chosen to keep the risk
of scalding to a minimum whilst still
complying with the requirment to
deliver water to the tap above 50°C
for health /safety reasons; see HS (G)
70 HTM 2040.
This system delivers fresh water from
the mains supply to the hot taps and is
designed to fulfil four basic needs.
1. Provide mains pressure hot water
with an appliance that does not
need a costly annual service.
2. Deliver hot water at good
pressures whenever you need it.
3. Operate as efficiently as possible
to cost-effectively meet your
household needs.
4. Provide hot water to every tap
of high quality. This is possibly
because it has not been allowed to
deteriorate in storage cisterns.
