Stokvis Plate Heat Exchangers boost hot water performance for 500-bedroom hotel

March 2019

Stokvis Plate Heat Exchangers boost hot water performance for 500-bedroom hotel

Econoplate plate heat exchangers (PHEs), from Stokvis Energy Systems, have been installed as part of an impressive overhaul of the domestic hot water provision within a 500-bedroom hotel at Stansted Airport.

The building services upgrade at the Radisson Blu, Stansted, has been overseen by Manchester-based, [PS]K Design Ltd leading to the specification of four C3A 1350+0R Econoplates to replace the original PHEs one at a time.

The quartet of Econoplates was supplied along with unvented kits and made-to-measure insulation jackets to further increase energy efficiency. Stokvis' own engineers carried out the commissioning of the units during July 2018; the scope of the work also included the installation of water softening equipment and a secondary return for the hot water service.

The senior engineer on the project for [PS]K Design, Steve Bartlett, explained: "The Radisson Blu, located close to the terminal at Stansted, not only has 500 guest bedrooms, it also offers conference and banqueting rooms, and a health club and various other facilities - together with a health club - so hot water demand is very high and subject to big peaks at different times.

"The original plate heat exchangers were struggling to cope so we decided to replace them with the four Stokvis Econoplates, knowing that they provide excellent performance and reliability, while the manufacturer also offers very good service. The new plate heat exchangers were selected to work at lower primary temperatures to maximise saving from setting back the boiler temperatures saving over 30% in energy costs. I have always enjoyed a very good relationship with Stokvis and this project has gone very well."

Stokvis Econoplate units offer a well-proven solution for the supply of hot water services in all situations where demand is high, including the commercial, medical, education and industrial sectors, as well as hotels and leisure. They achieve this through low water volume and high surface area using either stainless steel or titanium plates, while also avoiding the need for storing large volumes of warm water and the risk of Legionella contamination. There is a very wide range of options to choose from including bare plate units, while they are often specified in conjunction with fully modulating Stokvis Boilers, such as the EVOLUTION range, and other products including booster sets.

Stokvis EVOLUTION boilers connecting with boom in communal heating

February 2019

Stokvis Energy Systems' Econoplate H2 and the R600 Evolution series

The continuing housing shortage and the demographics of an ageing population are increasing the popularity of apartment living as well as sheltered housing schemes, and also fuelling rapid growth in the uptake of communal or district heating schemes. The new EVOLUTION boiler ranges from Stokvis Energy Systems are ideally suited to power such projects.

The R40 EVOLUTION and R600 EVOLUTION series represent the latest generation of Stokvis Energy Systems' long-established and widely-specified boilers, which can be installed along with the manufacturer's H Series Heat Interface Units (HIUs) to supply heating and domestic hot water to individual dwellings.

Using the R40 and R600 EVOLUTION boilers in centralised plant rooms provides a primary heat source for the HIU's with an excellent efficiency while saving landlords the headache of gaining access for annual gas safety inspections and maintaining individual units in each flat where space is often limited. Instead, connecting heating circuits to Stokvis H Series HIUs ensures residents can enjoy DHW and space heating comfort around the clock.

The Econoflame R600 EVOLUTION, in fact, offers outputs from 142 to 540KW and incorporates a patented downward firing pre-mix burner and stainless steel heat exchanger. Low weight and compact dimensions enables them to pass through standard, single leaf doorways on wheels that are incorporated with the boilers. They can also be installed in a cascade arrangement to share load.

Equally versatile, the R40 EVOLUTION wall hung range encompasses six models delivering between 56 and 138KW. These can be combined either back-to-back or in line to provide a maximum capacity of 1,102KW as a Modupak solution.

It is vital that developers or building owners such as social housing providers understand the importance of accurate specification to meet the special requirements of communal heating systems: including calculating combined demand of multiple households, as well as sizing the boilers and the HIUs to suit.

As a highly experienced supplier working with a network of installers, Stokvis Energy Systems can offer specifiers extensive design support from conception through to commissioning. This can include combining the R40 or R600 boilers with solar thermal input or other renewables and thermal vessels at the central plantroom and then coupling the plant to a number of WRAS approved H Series heat interface units that can deliver heating and hot water to a number of dwellings in an efficient and hygienic manner.
