  1. The £17 “deal” appears under their “existing customer offers”, but clearly local staff have wriggle room to offer this to anyone and everyone. Still not a bad deal, and currently on the short list to replace my Sky landline broadband!
  2. A triple coil in the new calorifier, and one of those immersion boss adaptors in the existing calorifier. Feed the “solar” heat to the coil of the calorifier nearest the tap first. Add a valve to choose between this calorifier coil or both in series as per the “webasto” circuit. You could link the two valve handles to give a single action changeover for bath day, although experience may favour individual control.
  3. So plumb the “engine” coils in series, with the flow going to the calorifier nearest the tap first. No need for a valve on this circuit as any excess “free” heat will automatically go to the second calorifier. You just need a single valve in the “webasto” coil plumbing to change between single calorifier nearest the tap and both in series on bath day. A single valve to achieve your stated aim. Pumped recirculation is fine in large installations like hotels where you need hot water fairly quickly at all taps, but seems a little complex for what you want?
  4. Try this: remove the pump and related pipework. Take the returns from each coil in the lefthand calorifier to the inlets of the coils on the righthand calorifier. Use two 3 port valves to change from lefthand only to both. Link the valve handles (or use a duplex valve) to change from grubby day to bath day. edit to add the theory. The left hand calorifier will heat up until its contents are at the same temperature as the hottest coil. At this point the temperature drop across the coils of the left hand calorifiers is effectively zero; meaning that the available heat transfers to the second calorifier automaticaly once you select “both”. On grubby days the righthand calorifier is nothing more than a fat cold water feed pipe for the lefthand calorifier. Buy a triple coil calorifier and plumb it in as the lefthand calorifier, and replumb the existing calorifier as the righthand one. disclaimer: typed under the influence of “Birra Maretti”
  5. Just like most bottled water then.
  6. I wonder how the figures stack up for a diesel generator driving a heat pump Vs a diesel engined combined heat and power unit?
  7. Its all about the box, or lack of it. All of the components for my “out of the box” solution are available delivered in or on a pallet, stillage, package, carton, blister pack, wrapping paper or bag. Box ticked ✔️
  8. This “box” seems a bit difficult to get out of, although I have seen some damage to the packing tape 😇 How about a compact combined heat and power solution? Heat recovered from the coolant and exhaust gas, and surplus electrical power (not being used for battery charging )for an immersion element. No storage tank required if you configure it for indirect cooling. The canal water passing through the heat exchangers can be diverted though filters (and a UV lamp unit if you like) for the bath rather than being discharged over board. Choose filters that can be back flushed during your normal bunkering routine. Going back in my box now, its a bit bright out 😎.
  9. Anything with a Yanmar part number is likely to be the one fitted in the head. The higher temperature ones used in the side of the black block usually have numbers in a different format. Happy to be corrected, but is this the higher temperature thermostat used in the single (standard) stat setup?
  10. You might wish to start a new thread on this subject as your figures indicate a setup at the extreme end of the "normal" range.
  11. I'm not sure that parts lists for the earlier engines were ever online; there are significant differences between your TNE engine and the current TNV range. Just take the old thermostat and cover to your local car parts shop, they'll usually find a match. The old one may have a bleed hole (you can drill your own if the replacement is the same in all other respects) which needs to be at the top (12 o'clock position) when refitting. You may as well speak to Barrus to determine which thermostat they now recommend for your particular engine. Be sure to be seated when you ask about prices 😉
  12. The "black block" replaces the normal thermostat cover; so the lower temperature stat sits in the standard position in the head, accessed by removing the domed nuts either side of the filler cap. The higher temperature stat is under the cover on the side of the "black block"; behind the lifting bracket in the photo, where the hose to the skin tank connects. It sounds as though the higher temperature stat has failed, so slightly less to remove; side mounted stats may need a little grease to hold them in place whilst fitting the cover (although some may be held with a spring clip of some sort).
  13. The model number and year aren't meant to be the same, it's just unfortunate that it looks that way. The 4TNE84-BME engine of 1995cc was, according to the handouts received during my course, used on the models 2000, 2001 and 2003. The model 2002 has hand written noted added during the course that suggest that latter ones used the larger 4TNE88-BME. The seven digit number after the model number suggests, along with the age of the boat, that this is the larger engine. The fuel filter is often a CAV type fitted by the installer. The air filter as listed is a Yanmar pt No 119808-12520, but may again be an installation specific part. The oil filter is however a constant between the two engine types; its been superseded a few times over the years, so Yanmar pt No 129150-35151, 129150-35152 or 129150-35153 should find a suitable alternative. The current listing is an entirely different No which I believe was essentially part of a housekeeping exercise to remove multiple numbers from the same filter fitted to many other engine types.
  14. Model 2002 was produced from 1999 to 2003 inc and was based on the Yanmar 4TNE88-BME engine of 2190cc. There was also a model 2200 produced from 1998 to 2000 inc based on the same engine and available as either 45 or 50 hp. My Barrus training notes include most of the sales leaflets for those years, except of course the model 2002! It would be a reasonable guess that the 2002 was initially available as a 40 hp during the period that both were in production. Later production models saw the water-cooled exhaust restricted to the 50 hp models.
  15. Make sure your Frome to London ticket is to “London International”. Its all about onward travel if the train from Frome is late. Apparently a “London International” ticket entitles you to travel on later Eurostar serviced if you are delayed. This from memory, as I don’t have the magazine article to hand.
