Navien 28kW Oil System Boiler Internal LCB 700 LS PLCB0028SH001

Navien has engineered this internal 28kW oil system boiler to reach an A+ efficiency rating standard when paired with three Smart Plus room thermostat controls. This LCB 700 unit is the UK market's initial oil boiler series capable of reaching A+ energy performance. Manufactured with stainless steel heat exchangers, the internal system offers long-term durability and high operational efficiency. Future-proof Blue Flame burner technology reduces NOx emissions while maximising fuel usage for the 28kW output. Fitting is simplified by a lightweight casing, flexible pipework layouts, and a joint PRV and condensate drain connection.
