ECONOFLAME BOILERS R3400

ECONOFLAME SERIES

R3600

Since 1985 Stokvis have been offering a range of fully modulating, high efficiency gas fired boilers. Researched and developed over the years, evolving through and culminating in the most comprehensive ‘state of the art’ premix, ultra low NOx and condensing range of products :- all exceeding part L Building Regulations; the full range of premix models are ECA listed, as is the R18 atmospheric range.

R2000 & R18 Series Features And Benefits ECONOFLAME FEATURES • Modulated gas valve and secondary air damper operated by servomotor. • Matching of part load conditions from 100%down to 20%. More efficient at part loads than conventional boilers, obviating need for many modules. • Gas and secondary air ratios controlled from one source. No possibility of error in control. • Servomotor signals indicate load conditions. Allows boilers to be sequenced for optimum efficiency. • Damper insulated, preventing downward heat radiation. Obviating requirement for heat absorbent base and helps maintain high efficiency.

• Atmospheric stainless steel, gas burner.

• Efficiency Curves Efficiency curves for different types of boilers

• Quiet in operation. Can be installed in areas where noise restrictions are paramount. • Complete burner including all gas and air controls can be removed on wheels. Easy to maintain, labour costs kept to a minimum. • Primary air controlled by inducement from modulated gas. No need for sophisticated controls and complicated maintenance. • Even secondary air distribution across burner. Ensuring even flame and high efficiency.

Boiler output in %

with stainless steel baffles. • High conductivity of copper. Meaning minimum size of heat exchanger, maximum output. • Copper resistant to thermal shock. Giving longer lifetime expectancy of heat exchanger (5 year guarantee) • Baffles give maximum turbulence of flue gases. Maximum heat extraction from flue gases giving high efficiency. • Substantially lighter than Cast Iron / Welded Steel boilers. Structural limitations are overcome when boilers are located in roof top plantrooms.

The R2200

is a fan assisted model with a two stage burner and is similar in design to the R2000 series.

• Smaller flue diameter than the atmospheric boilers. Ideally suited for replacement of cast iron/steel shell pressure jet boilers.

ECONOFLAME SERIES

R3600

Since 1985 Stokvis have been offering a range of fully modulating, high efficiency gas fired boilers. Researched and developed over the years, evolving through and culminating in the most comprehensive ‘state of the art’ premix, ultra low NOx and condensing range of products :- all exceeding part L Building Regulations; the full range of premix models are ECA listed, as is the R18 atmospheric range.

R2000 & R18 Series Features And Benefits ECONOFLAME FEATURES • Modulated gas valve and secondary air damper operated by servomotor. • Matching of part load conditions from 100%down to 20%. More efficient at part loads than conventional boilers, obviating need for many modules. • Gas and secondary air ratios controlled from one source. No possibility of error in control. • Servomotor signals indicate load conditions. Allows boilers to be sequenced for optimum efficiency. • Damper insulated, preventing downward heat radiation. Obviating requirement for heat absorbent base and helps maintain high efficiency.

• Atmospheric stainless steel, gas burner.

• Efficiency Curves Efficiency curves for different types of boilers

• Quiet in operation. Can be installed in areas where noise restrictions are paramount. • Complete burner including all gas and air controls can be removed on wheels. Easy to maintain, labour costs kept to a minimum. • Primary air controlled by inducement from modulated gas. No need for sophisticated controls and complicated maintenance. • Even secondary air distribution across burner. Ensuring even flame and high efficiency.

Boiler output in %

with stainless steel baffles. • High conductivity of copper. Meaning minimum size of heat exchanger, maximum output. • Copper resistant to thermal shock. Giving longer lifetime expectancy of heat exchanger (5 year guarantee) • Baffles give maximum turbulence of flue gases. Maximum heat extraction from flue gases giving high efficiency. • Substantially lighter than Cast Iron / Welded Steel boilers. Structural limitations are overcome when boilers are located in roof top plantrooms.

The R2200

is a fan assisted model with a two stage burner and is similar in design to the R2000 series.

• Smaller flue diameter than the atmospheric boilers. Ideally suited for replacement of cast iron/steel shell pressure jet boilers.
