ONE CROWN PALACE

One Crown Place is a dramatic, gleaming new addition to the London Iconic skyline.

YGHP were commissioned to find a solution to the heating
and Hot water demands for this development. The challenge
was to find a Heat interface unit (HIU) and Cooling Interface
unit (CIU) That had the performance to test against BESA HIU
regime, but also physically would not take up to much
valuable space for the home owner within the utility cupboard.
With HIU kW ranges from 53.5kW to 91kW YGHP were able to
offer the YGHP Indirect series. Keeping the footprint, the same
throughout the range. The Unit offered was a Hydraulic unit,
that gave all the benefits of stable control and lower
fluctuation issues than experienced with Electronic HIU’s. The
design criteria for the DHW was based on 75/35 with the space
heating load 75/45. Independent witness testing was arranged
tenant could make a choice, did they warm instantaneous
DHE with the keep warm on, a cost to the homeowner to keep
the DHW Plate heat exchanger warm. Or turn the DHW keep
warm off in times on non-occupancy. A benefit of no primary
water going through the Heat / Cooling meters and allowing
the building corridor primaries to also cool.
A total of 235 HIU and CIU were supplied, installed into a
off-site prefabricated utility cupboard. YGHP worked with the
PUC manufacture to ensure the units physically matched. In
order to meet the programme requirements, the units were
built with a buffer stock of two months scheduled deliveries in
mind.

INDIRECT SERIES
Heat interface units are a complete solution for apartments
for hydraulic separated systems.
Secondary system can be radiators or underfloor heating.
Balancing valves can be radiators or underfloor heating.
Stainless steel heat exchanger and thermostatic controlling valve to
have a stable temperature domestic hot water up to 23 It/min.
Stainless steel heat exchanger is used to hydraulically separate the
apartment from the main system.
Thermostatic controlled valves are used to control the secondary side
supply temperature.
Energy efficient electronically controlled pump controls the flow of
secondary side heating.
All the consumption of heating and domestic hot water preparation
can be measured by one heat meter and cold water meter.
All the piping is stainless steel.
