All Products Boilers - Condensing Gas Boilers - Gas Boilers - OilOverall Efficiency Efficiency within a model group will tend to vary by the size (capacity) of the unit. I have the temperature set to 120F, and when I open a faucet, the boiler ramps up, the water gets hot, but then the boiler cuts back and the water gets cooler, and this cNavien Learn More
Apr 29, 2013 · Boiler: Any vessel, container or receptacle that is capable of generating steam by the internal or external application of heat. There are two general classes of boilers. I.E., fire-tube and water-tube. Boiler casing: A wall protecting the different deck spaces from the heat of …Learn More
VFK 145 and VFK 155 are available in horizontal and vertical installation versions, VFK 125 for vertical installation Gas condensing wall-hung boiler ecoTEC plus Compatible with Vaillant range of wall-mounted boilers, floor-standing boilers and solar thermal collectors;Learn More
Sizes for packaged watertube boilers range from small, low pressure units (e.g., around 10 MMBtu/hr) to very large, high-pressure units with steam outputs of about 300 MMBtu/hr. Cast iron boilers are used in small installations (0.35 to 10 MMBtu/hr) where long service life is important.Learn More
A/C condensate drains & pumps: codes, installation, leaks, clogs, connections, troubleshooting & repair: This article discusses the inspection and repair or un-clogging of condensate disposal systems, including air conditioning, heat pump or condensing boiler/furnace condensate drains & condensate pumps, and their proper installation as part of our review of condensate piping, traps, drains Learn More
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.Learn More
Location where some chemical products are handled in small quantities and where these products may come only accidentially into contact with electrical equipment; such conditions are found in factory, laboratories, other laboratories or in locations where hydro-carbons are used (boiler-rooms, garages, etc) AF3 d) ContinuousLearn More
Clearance distances for outdoor HVAC compressor/condenser units: This article describes the recommended minimum (and maximum) distances to separate HVAC components from other building features, such as the distance required between an air conditioner or heat pump outdoor compressor/condenser or from a heating boiler or furnace to building walls, wiring, piping, other …Learn More
Vortex models include utility, external, boiler house and wall-hung. Grant's recent R&D breakthrough has future-proofed the full Vortex range to use HVO through making a slight modification to the boiler, such as adapting the size of the fuel injector nozzle, fuel pump pressure and blast tube.Learn More
