ECONOMATIC BOILERS FROM STOKVIS
November 2011
ECONOMATIC BOILERS FROM STOKVIS
The latest range of Economatic steel shell boilers is available from Stokvis Energy Systems. These are three pass reverse flame boilers, for use on gas and oil, with capacities of 93kW to 3488kW in standard units.
Features include a front tube plate flanged towards the combustion chamber which prevents hot spots, reduces thermal stress and extends life expectancy. Thermal energy losses through conduction are kept to a minimum due to the high levels of insulation both externally and internally on the boiler door, which is two-way opening with multi way adjustable hinges for easy access.
The boiler has internal water baffling which directs cold water away from the areas most susceptible to condensation. In order to reduce the time when condensation is formed, Stokvis has a minimum return temperature thermostat integrated into its system, preventing pumps from operating when the boiler is cold.
Other features include the precision engineered shell design which results in a very high thermal efficiency of ≥91%. The design ensures low carbon monoxide and nitrous oxide emissions.
REDUCED CARBON EMISSIONS IN SHELTERED HOUSING

STOKVIS PROVES CATALYST FOR REDUCED CARBON EMISSIONS IN SHELTERED HOUSING
Catalyst Communities Housing Association has opted for solar thermal equipment from Stokvis Energy Systems at a refurbishment of heating plant at O’Grady Court, in Ealing, west London, as it seeks to reduce carbon emissions from its housing stock.
Catalyst Communities Housing Association (CCHA), the largest member of the Catalyst Housing Group, provides more than 11,000 affordable homes in London and the Thames Valley. CCHA is committed to sustainable development and lowering the carbon footprint of all of its housing stock.
O’Grady Court is a sheltered housing accommodation block built in 1984. It comprises 62 predominantly one-bedroomed, flats, a lounge, laundry facilities, garden, community centre and hobby room. “The heating plant was in need of replacement,” said David Manuell, designer at Promode Building Services, the firm responsible for the design and build heating contract. “We opted to replace the old atmospheric boilers and direct gas-fired water heaters with high efficiency, wall-mounted condensing boilers and a plate heat exchanger from Stokvis.”
As the footprint of the new plant was dramatically reduced, this liberated space in the plantroom. “With the extra space we could now fit a Solar Thermal Vessel in the plantroom so we’ve put 12 sq m of solar thermal equipment on the flat roof above the boiler room,” said David Manuell. Five Stokvis Riomay evacuated Ecotube solar collectors will offset around 10,500 kWh per annum that would otherwise have to be generated from the gas-fired boilers.
Stapletech were the installing contractors on the project.
The Stokvis Ecotube is an advanced form of evacuated tube solar collector which is designed to maximise the solar energy absorbed and minimise heat loss through radiation. Developed and patented by Riomay, Ecotube has substantially reduced the amount of ‘parasitic’ energy lost by most evacuated tube systems (energy used up by the system itself during the process of converting solar energy to heat).
As a result, the system requires smaller pumps to circulate the fluid in the evacuated tube collector which means that there are fewer drops in pressure through the system, giving a more sustained level of heat than almost any other system.
Stokvis has experience of the technology in many different sectors, including housing associations, schools, public swimming pools and private sector businesses.
