Immersion Heater substitute Help!
Hey guys - I have a water heating system run off the CH, but it is simply a microbore coil inserted into the immersion heater hole in the cylinder that has hot water pumped around it to heat the water in the cylinder like a heat exchanger. However, it has become corroded internally and flow is very low and not performing. The best solution is to replace the cylinder and do it "properly" or just stick an immersion heater in the hole. Does anyone know where I can get a replacement microbore heat exchanger like the original for a quick solution? Combined brains of DIY banter should be able to solve this!! Regards, Tony kendall

Regards, Tony kendall Why not just replace the microbore thing, and add inhibitor to your system so it doesnt go the same way. You can get microbore from any BM or shed, and just bend it to shape like the old one. The more length of pipe you get in there, the more heat exchange can occur. If you can put 2 or 4 lengths in parallel that will work much better, as you'll get far more flow. You can get 4 way microbore manifolds for very little, theyre just a metal plug with 4 holes in.

Thanks everyone. In the event I managed to unblock it using a high pressure hose. The thing was not quite as I thought when I got inside - 15mm pipe straight down to the bottom then similar with fins curled around this back up to the top. Only put off the evil day but thanks for advice. Tony
