  3. The calorifier IS a heat exchanger. Connect inlet to the cold water supply, preferably with a non-return valve before the connection, and ideally with an accumulator between the NR valve and the calorifier. This will help to avoid water bleeding off from the relief valve. Connect the engine pipes to one coil (in the case of a vertical calorifier connect to the lower coil, and ensure the engine water circulation is from bottom to top). Connect outlet to your existing HW system with an isolation valve. All logical really.
  4. ISO requirement is to support the pipe on both sides of any joint within 150mm, as far as I can recall.
  5. Like many forms of construction, the hull strength partly derives from the convex shape. This is especially true of ferrocement. A nicely shaped yacht like the one on post #11 is an ideal shape, and the hull thickness may be no more than an inch or so. A narrowboat is quite the reverse, and the construction will tend to be heavy in comparison.
  6. You haven't said if you plan to replace the fenders later. There are plenty of products that can be used to make either permanent repairs or temporary repairs. If the holes are above the static waterline they are only going to suffer from splashing (as long as you are not related to Phylis ) For permanent repair I would mix an epoxy filler using a kit bought from the swindlers, comprising epoxy resin, hardener and microfibre additive. The key is to prepare the hole well inside (if possible). This is not the same product as 'epoxy putty'. For a temporary repair I would use a good adhesive sealant - your swindler will guide you. I used Bond-It PU18 polyurethane for bonding rope fender around the gunwale, it is like a very hard rubber when cured - very cheap on ebay and very easy to use. Cleans up with white spirit.
  7. er ...... gas bottle .................. ??
  8. and it is worth pointing out that the standard beam on the Mon & Brec is 9ft, so there are purpose built boats on the canal.
  9. As long as the locker construction complies with the BSS there is no reason why it shouldn't be located inside the cabin.
