(1200-2400 MBTU/h)

Rheos+
Fully-modulating, fully condensing, compact, sealed combustion, low NOx and up to 98% efficient. Laars Heating Systems engineers designed the RHEOS+ boiler/water heater to provide ultra-high performance and superior efficiency. Seamless combustion modulation from 25 to 100 percent of full input maintains maximum efficiency and helps cut operating costs as much as 50 percent. The heart of every Laars RHEOS+ boiler/water heater is the patented, double-row, copper-finned tube heat exchanger and a 48-row stainless steel economizer that maximizes water heating surface area. Coupled with a powerful stainless steel burner and an industrial grade gas control system, this design delivers the highest heat transfer per square foot of floor space available.

NeoTherm
NeoTherm is a direct vent, sealed combustion, condensing boiler with 90+% AFUE that modulates with a 5 to 1 turndown. The boiler features an ASME stainless steel heat exchanger, integral boiler pump and low NOx emissions, for a package that's easy to use, and easy on the environment. SM NeoTherm is built standard with the new LAARS Integrated Control System that puts the ignition control, temperature control and high limit in one user-friendly device that does it all. This control system has PID logic, indirect water heater control, outdoor reset, frost protection, and loads of other features. It works with othercontrols to become part of a multiple boiler sequencing control, and works with building automation systems.

Rheos
The Rheos is far and away the most compact and cost-effective heating system in its rating class. Seamless combustion modulation from 25 to 100 percent of full input maintains maximum efficiency and helps cut operating costs as much as 50 percent. The system uses a patented double-row coil configuration to create maximum heat transfer surface area and balanced water flow. Coupled with a powerful burner, the Rheos is able to provide industrial grade service for hydronic and volume water applications.

Pennant
Pennant boilers and water heaters feature convenient, modular construction that separates the burner trays, gas train, and blower assembly. All Pennant models use lightweight insulation, glass-lined cast iron or bronze headers, and non-ferrous waterways. The 10 tube heat exchanger design uses finned tubing for the quickest and most efficient heat transfer. The modular construction makes Pennant units easy to install and maintain. The Pennant's venting connections are interchangeable between top and back.  Water connection may be reversed to accommodate left or right side piping.
