We live in a world where most theoretical ideals can only be approached rather than fully realized.  

The LG Hydro Kit is an indoor heat exchanger for LG variable refrigerant flow systems capable of transferring heat or cooling energy expelled from the air-conditioning process to water, offering further efficiency of LG heat recovery and heat pump systems. 

Danfoss won an AHR Expo Innovation Award for its Interlaced Micro Channel Heat Exchanger, or iMCHE, which integrates multiple circuits into a single coil with a shared air heat transfer area, controlling each one independently by a multi-circuit system. 

Navien’s new NPN (premium non-condensing) series of tankless water heaters is offered in the NPN-U (universal) and NPN-E (exterior) options, both of which will be available in 160,000 Btu/h, and 199,900 Btu/h models for either natural gas or liquid propane.

The new MagnaTherm HTD series of condensing boilers and volume water heaters boasts real-time O₂ trim compensation that maintains ideal air-to-fuel ratios, full 20:1 turndown on all sizes to match varying load profiles and the Laars Linc icon-driven control system.

The market for pellet-fueled “biomass” boilers continues to grow in North America. This market expansion is driven by several factors. 

EVAPCO’s Advanced Technology ACC (Air Cooled Condenser) is specifically designed for the power generation industry.

All boilers that burn hydrocarbon fuels (gas, oil or wood) produce water vapor as a byproduct of combustion.

Extended protection applies to units specially engineered to streamline tankless-for-tank projects by reducing installation time and costs.

Energy savings decrease with higher heating loads.
