The Navien LCB 700 LS 28kW Oil System Boiler is designed for larger homes needing reliable central heating and ample hot water, especially those with multiple bathrooms. Its key benefit is an A+ energy rating, achieved through advanced Blue Flame technology and smart control systems, leading to significant energy savings. A potential caveat is that the A+ rating is contingent upon installation with three Smart Plus room thermostats.
