Econopak burners modulate between 30% and full load allowing varying loads to be matched. All models have atmospheric burners meaning very quiet operation. They are very light weight to output ratio – roof top installation or similar is possible. Econopak is ideal for large hot water demands. e.g from 989 litres/hr @ 60oC (delta T 50o C) to 17,177 litres/hr @ 60oC (delta T 50o C). Extruded finned copper heat exchangers give rapid heat transfer. Stainless steel manifolds – longevity and potable water quality. Installations throughout Europe – credibility established over many years.
