Hi,
A short cycling boiler at Christmas and evidence of sludge prompted me to fit a magnaclean2 and put a couple of litres of sentinel x800 into the system and circulate this for a few months till the weather improved.
I am now thinking of draining the system and restoring full operational efficiency to the boiler by using my domestic pressure washer connected to some suitable flexible pipes to back flush the system, each radiator and the boiler's heat exchanger via this pressurised flow.
Then an idea surfaced, in that pressure washers lend themselves to the introduction of water bourne abrasives via a venturi. But instead of inserting a light abrasive into the flow why not use bicarbonate of soda as the fizzing aids the removal of contaminates but will not harm the materials of the heat exchanger or so the theory goes...see soda based blasting via a Google search.
What is the forums view of using this blasting technique on the heat exchanger? I would welcome your practical advice before I take the plunge.
Boiler is a Worcester Bosch FS30cdi
Cheers
Joe
