I have a combi boiler that has no mag filter and the heat exchanger is getting full of crap from the system, which is costing me money (about £130) to get cleaned every year. I had a couple of plumbers round, one said he could fit mag filter for £300, which I assume would be on the flow, since the return pipe is tucked up in the corner and is not accessible to fit a filter. Another plumber quoted me about £850 to remove the boiler off the wall, and move the pipework so a filter can be put on the return (plus a new flue and flush). I'm not sure if its worth spending that much to get the filter on the return ("optimal" according to magnaclean) rather than the flow ("acceptable" according to magnaclean, but not my plumber!) ? Thoughts?
