Simple job

By
, Aberystwyth
" Bought from Screwfix as it was the best price I could find.
Got it home, drained some water from a radiator opened the plug at the top and poured the x100 in through a funnel and a bit of hose. Plug back on, bled the radiator and it was done. Simple job and I've protected my system.

" Buy it for the best price at Screwfix. Add it to your heating water system and let it do the job. Keeps the whole system clean and will probably result in a more efficient heating system. Simple and effective. "
