Overview
- Zhelyazko Yanchev advises clearing and dusting radiators and nearby areas to restore airflow and maximize heat output through natural convection.
- Homeowners are told to bleed radiators to release trapped air that causes cold tops, with an engineer calling it a simple five‑minute job followed by a boiler pressure check.
- Hot tops with cold bottoms can signal internal sludge made of rust, dirt and limescale, which may require a system‑wide power flush by a professional or a careful DIY approach.
- The guidance is being promoted as temperatures fall, with UK outlets noting forecasts for higher household energy costs from January after Ofgem’s latest price‑cap decision.
- Additional tips include improving insulation, using reflective foil on external‑wall radiators, setting programmable or smart controls with TRVs, and lowering thermostats to trim costs.
