Stokvis EVOLUTION boilers connecting with boom in communal heating

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.
