WPB with Integral Heat Store or WPB with external Buffer tank?

    Finally narrowing the wpb search to two/three options. Would appreciate any opinions as to the merits/demerits of a boiler with integral heat store (205 litres) versus a boiler that requires external buffer storage. For info, I have UFH installed. Additionaly, the boiler with integral storage does not modulate. Thanks in advance, boots

    Am not familiar with the abbreviation WPB except for water proof board so am confused:confused:

    Sorry ircoha.....wpb in this context meaning Wood Pellet Boiler. Just to clarify, I'm wondering what are the pro's cons of a WPB with integral heat store versus a wpb feeding an intermediate buffer tank. For info., I am installing a 300litre cylinder in a pressurised system & as per previous post, UFH.
