It must be a brilliant thing, acording to the testimonials J.P Westall
of Hexham fitted it to his OIL FIRED system and his GAS bills went
down.

Presumably his oil bill went up as a result of the whole house becoming
a lot warmer.

Did you also note that one of the case studies was about a 'heating
engineeer' who had no idea on how to fix his own heating system.

The clue to these miraculous improvements are contained in the fitting
instructions.

Drain system.
Re-commission as per the boiler manufactures instructions.

Any competent plumber will bleed the radiators during the re-commission.
