INTRODUCTION
For over 85 years, Kingspan’s unvented hot water
cylinders have continued to meet the evolving and
demanding hot water needs of homes in the UK and
Ireland.
When installed and maintained in accordance with
this manual, Kingspan cylinders will reliably store and
generate hot water for years to come. This manual
details how to prepare, install, commission, service
and decommission unvented hot water cylinders
with a separate external thermal expansion vessel. It
covers direct, indirect, solar and heat pump models. A
separate insert sheet contains specific technical details
for your chosen hot water cylinder.
As well as comprehensive instructions for installers, the
manual provides guidance and guarantee information
for homeowners.
For queries not referenced in this manual, our specialist
technical helpline can provide support. Further
information about our product ranges can be found in
our sales literature and on our website.
Benchmark places responsibilities on both the manufacturer and installer. The purpose is to ensure that customers
are provided with the correct equipment for their needs, that the equipment is installed, commissioned and serviced
in accordance with the manufacturer’s instructions by competent persons and that it meets the requirements of the
appropriate Building Regulations. The Benchmark Checklist can be used to demonstrate compliance with Building
Regulations and should be provided to the customer for future reference.
Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code
of Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme.
