  1. Best chimney cowl for diesel stove?

    No slots in the skirt. Only the top and bottom are open.
  2. Best chimney cowl for diesel stove?

    My Bubble runs quite happily with a 4" S/Steel flue pipe inside a normal boat chimney. This 'double skinning' helps the draught as it keeps the flue warm for its whole length. Attached to the top of the S/Steel pipe is a Swedish cowl, which has a skirt around the cap on the top. This eliminates down-draught in all but the strongest wind. Y our bubble incorporates a draught stabiliser as shown in K K's lower picture. The Swedish cowl looks very similar to the rearmost example in his first picture.

    If you read my previous posts, you will see it was a new boat. It falls under the auspices of RCD and the BSS does not come into play until it is 4 years old.

    As I've already said and explained, if I've passed on erroneous info, then 'sorry'. The Broker I referred to was one of the reputable ones, and probably referred to the RCD rules as the age of the boat would not have bought it under the auspices of BSS. When (and if) my Morco needs replacing, I shall do it myself, and would consider one of these.
  5. No More(co)

    Mike, As I said, I,m not liveaboard, so can't be bothered to trawl through the BSS. I was basing it on a comment made by a well known broker, who when valuing a craft of an acquaintance, said that as he did not have a commissioning cert. for the gas installation, they could not handle the sale. It was a (very impressive) self fit out, but as boat was only 3 years old, It may have been a RCD transgression instead of BSS. As already said, I'll happily stand corrected.
  6. No More(co)

    As I understand it, the regs for liveaboards are the same as for hire craft, which requires gas work to be done by a 'competent person', which would require a new installation to be certified and commissioned. If not, I stand corrected. As I don't live aboard, I can't be arsed to plough through the BSS.
  7. No More(co)

    Unless the Manufacturers Instructions specifically discount installation in a boat, then BSS has to assess the installation complies with them. There is a list of 'usual suspects' that makes reference easy for the examiner when completing the paperwork. And yes, for liveaboard, there should be a commissioning certificate, but that applies to all gas installation. I bet there's not too many have that as the boat is probably not liveaboard at the time of inspection
  8. Thermo syphon or pumped

    Have you done any calculations to estimate the heat the coil is likely to produce in relation to the heating load? With so much exposed pipe in the coil it is likely to be very inefficient. A solution could be to insulate the coil and sheath it in another tube.
  9. Thermo syphon or pumped

    Thermo syphoning will not be effective downhill, you will get some conduction, but nothing significant. You can install a small pump on the backward leg that you can control with a pipe stat. so that when the back cabin gets hot, the pump will switch off until your lower setting is reached. Your horizontal run may work, but will take a long time to warm up. I have just installed a pump controlled by the flow pipe temperature to assist a thermosyphon over 40 ft which is almost horizontal and has run satisfactorily(ish) for 28 years on 15mm pipework. There was only one radiator which omly ever got 1/3rd to 1/2 hot. I installed the pump on the return to the boiler, controlled by a thermostat on the flow pipe, set at 65oC. The radiator now gets hot all over within 5 mins, and the pump runs for a couple of mins at a time every 10-15 mins. Once the boat is warm, the pump can be switched off. Your difficulty will be that you probably need 2 pumps, unless you can put a pump on a commoned return into the boiler.
  10. Most crossed road ?

    With regard to bridges framing bridges, a contender must be the Staffs & Worcs between Aldersley and Autherley Junctions, if you count the pipe bridges into Barnhurst Sewage Plant. There are & if I recall correctly.

    Whilst my Morco is working, I'm not going to spend £170 + extras (and more work). But if this is all that is available, then there is no option. A perusal of the installation instructions says " Ensure the 1.5v batteries are installed with correct polarity, so my guess is that there will be 4 cells in series equating to 6volts. Easily supplied from the normal 12 volt circuit. I see there are 10 and 14 litre versions which offer greater performance than the Morco.
  12. No More(co)

    The data shows flame failure is monitored by ionisation. In practice, this is faster than a conventional thermocouple. Muck on the probe would stop it lighting, not keep it lit. This must mean the battery is an integral part of the control circuit, and one wonders what batteries are used, and how long they last. Having said that, it would not be above the wit of man to adapt the 12v power on the boat to power it direct, or replenish rechargeable batteries.
  13. Lockgate Refleks stove - lighting

    I would have thought a layer of soot around the pot would have been detrimental to efficient combustion, as it would impair the heat build up in the pot that is required for efficient vaporisation. Clean pots and catalysers make them so much better.
  14. River canal Rescue, worth joining?

    After 28 years without membership, I joined last year. Pre RCR, the worst I had was a failed starter motor, which on Perkins 4108M is an out and out special, I was lucky to be in Lincoln and a short bus ride away from the Lucas Main Service agent. As we now cruise longer and further, (and the knees and back are not so supple), I reasoned that having a 'one call' number from anywhere in the country was an advantage. Silver membership also gives replacement parts cover, granted with some caveats, but this is still a good deal. You can't blame RCR for conditions, as there are always some who will push the boundaries bordering on fraud. Being a member does not stop you being responsible about boat ownership, with regular servicing, carrying first line spares, and carrying out minor repairs without their involvement. I accept there are some who would take the attitude 'If I'm paying for it, they'll jollywell provide it' but that is folk. I know some folk who carry a spare wheel in their car, but would still call the AA for a puncture.
  15. Lockgate Refleks stove - lighting

    Diesel stoves can be difficult to light if the combustion chamber is closed off immediately. The only combustion air that it can get is through the burner base, and if the flue is preheated, then it will 'lift' the flame from the fuel. If you leave the door or top loose for a few minutes, then the diesel has the chance to reach vaporising temperature, so this is what burns instead of neat fuel.
