The NHBC
is the UK’s leading warranty and insurance provider for new homes, setting
standards for registered builders and working to help improve the construction
quality of the homes they build.
They
recently announced the launch of their 2019 Standards, which will become
effective from 1st January 2019. The standards apply to all properties with
foundations laid on or after that date.
Evinox
are happy to see some updates to ‘Hot water services’ in the new standards,
where changes have been made to some of the flow rates and supply temperatures
at the outlets.
For
example, the supply temperature at the kitchen sink has been reduced from the
previous 60C to 55C, which is in line with the delivery temperature that was
selected for the majority of Heat Networks, during the last year.
Helen Gibbons,
Evinox Technical and Design Manager, comments: “This change to the outlet
temperature is a very positive development as it will enable district and
communal heating system flow temperatures to be reduced, something which is
especially important for the growth of 4th
Generation Heat Networks in the UK.
"In addition,
the lowered DHW temperature combined with the new table in the NHBC standard
for simultaneous hot water use, will give design engineers the confidence to
reduce the kW demand for individual properties, something which will improve
both efficiency and cost of UK Heat Networks.
“Whilst we are very
happy to see that the required temperature from the kitchen outlet has been
lowered to 55C for 2019, we do hope to see this further reduced to 50C for heat
network developments using instantaneous DHW heat interface units in the near
future.”
