Boiler Applications
Singular combi wall boilers
provide efficient heating and
plenty of hot water for many
residential applications. There are
two different models to choose
from: 155K BTU and 199K BTU.
Both can make enough domestic
hot water for most residential
bathing needs.
Superior Design
& Components
Depending on inlet water
temperature, the 4000 can
run between 2 and 3 showers
and the 5200 can run 3 showers
plus a dishwasher. There's plenty
of endless hot water available
with Singular. Both models have
a small footprint and are under
80 pounds, making installation a
breeze. Features like an exhaust
gas outlet sensor and a standard
inlet filter screen to keep out
debris provide extra protection
for the boiler.
