The ABSOLUTE “ABS SERIES” of hydronic heating condensing boilers is a combination of more than 35 years of North American and European engineering experience in condensing boiler technology.

The ABSOLUTE “ABS SERIES” utilizes a durable sectional cast aluminum heat exchanger engineered and designed in Europe. The cast aluminum provides a robust corrosion resistant heat exchanger that allows for ultra-high efficiencies with the added benefit of a small light weight boiler foot print. The ABSOLUTE “ABS SERIES” heat exchanger also provides additional efficiencies with large water ways, reducing the pressure drop through the boiler! We are so confident in our heat exchanger, we provide an industry leading warranty.

The fully water cooled combustion chamber host a knitted metal fiber premix burner. A turndown ratio of 10:1 allows for ultimate combustion control and reduces short cycling of the boiler. With precise combustion control the ABSOLUTE “ABS SERIES” is able to achieve CO2 levels that maximize condensation of the natural gas. Low NOx and CO emissions are the standard with the ABSOLUTE “ABS SERIES”.

The ABSOLUTE “ABS SERIES” incorporated the Honeywell Sola boiler control system for ultimate boiler control. The Sola allows for quick and easy set-up of the ABSOLUTE “ABS SERIES” of condensing boilers.  The user friendly touchscreen control ensures simplified monitoring and diagnostics along with: multiple boiler configuration (eight boilers), remote monitoring, fault history, trend analysis, boiler status, communicates via 3-wire RS-485 ModBus™ protocol, DHW priority.
