The Baxi 5115060 Rear Insulation is a genuine replacement insulation panel designed to fit at the rear of your boiler’s casing, helping reduce heat loss and improve overall thermal efficiency. By insulating the back section of the appliance, it supports quieter operation, helps maintain stable internal temperatures and protects surrounding surfaces from excessive heat exposure. Good insulation also contributes to improved energy use and reduced fuel costs over time.

This rear insulation panel is compatible with Baxi Duo-Tec, Megaflo and Platinum Combi series boilers that specify part number 5115060 in their parts documentation. To ensure correct fitment and optimal performance, always verify the part number on your existing insulation or consult your boiler’s service information before installation, as panel shapes and sizes vary between models and output configurations.

Supplied ready to install, the 5115060 Rear Insulation fits directly into the boiler’s rear casing using the original mounting points without modification when fitted by a qualified engineer. Choosing this genuine Baxi component helps restore proper thermal insulation, supports efficient boiler operation and maintains internal temperature stability in compatible Duo-Tec, Megaflo and Platinum Combi boilers.
