A dual-fuel heat pump, such as Lennox’s XP-14, will cost about 20 to 25 percent more (including installation) than an A/C. Depending on your region and fuel costs, however, it can pay for itself in five or six years. Heating With a Dual-Fuel Heat Pump WebAug 3, 2024 · Abstract. Ejector-driven systems have the ability to operate at high efficiencies, utilizing recycled thermal energy as a power source. For a typical ejector heat pump (EHP) system, the increase of the condenser temperature reduces the coefficient of performance (COP). In addition, if the condenser temperature is higher than the critical … how about this now
