Thank you guys! We have never had enough hot water since we bought the boat, it is only recently that I noticed the temp guage showing her running cool(ish) but that is quite possibly how it has always been. The engine is a Nanni 4220 HE, as far as I know it is the boats original - 1985 Broom 29 The calorifier is horizontal but as near as the eye can tell the higher hose is level with the engine, photo attached where you can see the hoses running parallel and level. In my first photo the return hose is the one marked 2, it goes into the base of the housing you can see where the brass is showing, as far as I know this houses the impeller ?? Am home now but can get more photos tomorrow pm, I haven't got a user manual though I'm afraid.

Thank you so much for your patience John... A photo it is! Where I have marked 1 goes to the higher connection on the calorifier, no. 2 to the lower. With the engine cold and running at idle both warmed up at the same rate. With the engine still running I pulled hose 1 off, coolant came out straight away, I replaced it and did the same with hose 2 with the same result. Now in an attempt to understand the system better I have been reading up similar situations online and I wonder if it's possible that these two hoses are connected wrong? I understand this is not uncommon. When I removed hose 1 the coolant flowed from the hose, when I removed hose 2 the coolant flowed from the engine... this was the opposite to what I expected. Although I cant access the calorifier the hoses at the engine are easily accessible. Is there any point in me switching these hoses to see if I'm right?

Yes, you can add prop foul to the breakdown cover with Sutton Staithe Boatyard.

Hi John, I'll admit I'm struggling to identify what goes where! The two hoses to/from the calorifier disappear toward the calorifier but I can't get near enough to it to see which is which, certainly can't reach the hose connectors at that end. It is mounted horizontally in a space I am not built to enter 🙄 At the engine end of the hoses they run next to each other on a bulkhead, both became hot to touch as far as I could reach but that wasn't far. I fear that I may have to be calling the boat yard again to be on the safe side.

I'm trying to find/release a suspected air lock (Engine runs cool, very little hot water at tap, thermostat changed) On top of the Calorifier is a red valve, when pressed water runs freely into bilge but I cant see where from. What am I doing? Will it help? Should I stop?

It'll be interesting to see if it works Chris but I have to say "it ain't pretty"!

I think that's a radio Griff 😉 👍

I have signed up with Sutton Staithe for some years and although I haven't called them out (so far) I know from talking informally to them that they really give a dependable and efficient service.

I strongly suspect that is an understatement. Congratulations on sailing her again 👍

Has anyone used them for pumpouts and fuel? They have a good reputation and would be very handy for me but I never seem to see anyone or access to moor, when passing. Is it a case of just coming alongside and someone will appear?

Brilliant job!

Great photos they are too 👍

It must have felt a bit like coming home to take the helm of SR1 again 🙂 Lovely photos too 👍

I had a camera sent through arteries once, results not as good as yours but OK for my age. The trouble was that when the camera reached a certain point my heart stopped! Poor Gill was in the waiting room when a crash team charged through to where I was being examined in full gear including the white wellies (funny the things you remember) Fortunately the team doing the camera work resussed me and I was just kept in 1 night for obs. Since then I like to think I've been rebooted, it always does the power of good to a windows PC 😂

He'll be missed, a good, helpful and fair examiner and a nice guy too 👍

Chris, you will have seen the new line of the beach, it is to be hoped that where the old cafe and carpark were protected but have now gone has in a way been a natural erosion of a somewhat artificial headland! At the moment it looks nice and should at least be stable until next winter then we shall see. I'm hoping not to become a sea front property in the near future! 🤞

Happy Birthday Ian, hope you enjoy your celebration dinner after all your work in the garden 👍 🍷

Used Tim Waters for the 2nd time in January, very helpful and only £130

Beautiful Chris and no finer start to the day ☕

Nice work and a bargain as well! 👍

The honest answer is I don't know. It looks like its part of the block/head and I would say cast iron probably.

Great information and advice as ever John, many thanks 🍺

The housing is next to the heat exchanger on mine and the 4 bolts are nicely accessible. I remembered what you said though and proceeded with as much caution as I could, which wasn't much I guess.... 3 of them sheered off! At least I knew from your post that it could happen so I didn't tear my hair out lol The lovely people at Sutton Staithe Boatyard are coming next week to fix it for me. I know I could attempt this as a DIY job but it's always best I think to know my limitations and not risk making a bad job worse 👍

Good thought, I'll do a thorough check and see what turns up 👍

Just in case... Can images be disabled for this thread? 😂
