Heating & domestic hot water boiler The Baxi Luna HT 380 is a combination heating and domestic hot water boiler that produces 3.9 gpm of dhw at sT80 F. The fully modulating, condensing boiler has a modulating range from 112,601 Btu/hr at high fire down to 32,804 Btu/hr, and can achieve thermal efficiency up to 98% (afue 92.5%) for low temps. Ideal for in-floor radiant, hydronic air handler, baseboard radiator and snowmelt, boiler emits 90% less CO and 80% less NOx than conventional heating products. Marathon Intl. |

MPC commercial boiler The mpc has been engineered from start to finish with specifications that meet or exceed the competition in every way -- from the 3-pass sectional cast iron design, centralized 4-inch supply and control manifold, and return water mixing tube (rwmt), to a totally new jacket and a unique, integrated boiler control system. Efficiencies range from 88.4 to 90.0% combustion efficiency on oil, and 85.8 to 86.3% on gas. 3-Pass combustion airflow through the block maximizes heat transfer contributing to higher efficiencies and substantial fuel savings over single-pass boilers. The integral return water mixing tube (rwmt) protects the boiler from low return water temperatures by evenly distributing the return water into each section. This built-in protection eliminates the need for external mixing devices and complicated piping arrangements, saving the installer valuable time and money. Burnham Hydronics. |

Cost-effective thermal storage Superstor contender solar is a new line of glass-lined indirect water heaters, designed specifically for solar thermal applications. The new units store hot water from one or more solar collectors, while also providing either electric or boiler (pictured) backup for when the available solar power cannot meet hot-water demand. The units are eligible for a federal tax credit when connected to one or more solar panels. Heat Transfer Products. |

‘Condensing 98’ tankless water heater “Condensing 98” tankless water heaters feature exceptional 98% efficiencies. These “Eco-Navi” models offer significant energy savings, reduces over 420 lbs. of CO2 per year per unit, use pvc venting up to 100 feet and offer superior performance over the standard mid-efficiency tankless units on the market today. Unique mini-tank/pump combination gives hot water quicker and saves water. Navien. |

Commercial line of tankless water heaters New, improved and more efficient ASME accredited and nsf approved commercial line of tankless water heaters continue to hold the position as the best in the industry. The original 084 series are now upgraded to 0931 series, which now yield at 9.3 gallon per minute at 45 F temperature rise with a minimum Btu of just 11,000 and a slight increase in maximum Btu to accommodate the larger flow. The 1321 series accommodates 13.2 gallon per minute flow rate. These heaters are now updated with stainless steel shell-casings to better accommodate the commercial environment and to give a unique and an aesthetic presence. The new generation commercial grade tankless water heaters are now equipped with dual flame burners and larger and thicker heater exchangers. Noritz America Corp. |

Tempra tankless electric water heaters On-demand, electric water heaters feature an advanced microprocessor control that allows the exact water temperature to be set via a knob and digital display on the front cover. The advanced technology ensures that the water temperature will not deviate from the set point. The compact, energy-saving Tempra provides an unlimited supply of hot water, heated as it flows through the unit. Stiebel Eltron. |

T-M50 tankless water heater Scheduled for a first quarter 2008 release, unit uses two heavy duty heat exchangers to produce up to 380,000 Btu/h. The dual system ensures that if one unit were to break down, the other would continue operating without any interruption, thus avoiding emergency situations. The new exchangers also utilize technically advanced copper, making the unit much more resilient against erosion and leaks. Takagi. |

ProPEX Auto rotation adapter Installers no longer need to rotate the expander tool or the pex tubing itself by hand when making Propex connections. The adapter automatically turns the expander head on each expansion of the tubing, eliminating the need for any manual rotation. The adapter is especially effective in tight spaces where manually turning the tubing or the tool is difficult. Measuring only 1.9" in length and diameter, the Propex Auto Rotation Adapter expands proprietary PEX tubing in five sizes from 3/8" to 1" and fits onto all Propex Expander Tools (manual, air and battery), except for the new Propex 200 model.

Condensing high efficiency gas boiler The Ultra, features PhD technology (Precision Hydronic Data) -- an intelligent system that delivers precision hydronic heating and hot water needs while maximizing efficiency by measuring and responding to the data parameters of a heating system. Available in five sizes, the Ultra features a 92.8% afue. Boilers have a low-temp seasonal efficiency rating of 98% and exceed the toughest air quality standards for low NOx emissions. Weil-McLain. |
