A Solid Choice for Off-Grid Properties

I use the Navien LCB700 LS/LSX System Oil Boiler mainly on off-grid jobs and it has been a very solid option for larger rural properties. It is ideal where a separate hot water cylinder is needed and works well in farmhouses, cottages and family homes with higher hot water demand. I like that there is an internal and external option, and the build quality is good. A reliable boiler range that suits this type of property very well.
