If your radiators aren’t heating properly, your system may be clogged internally.
Dirty Systems Don't Heat Properly
Over time, sludge and debris build up inside your heating system, reducing performance and efficiency.
Common Signs Include:
Cold radiators (especially downstairs)
Black or dirty water when bleeding radiators
Cold spots in the middle or bottom of radiators
