While it appears to be well established that frequently cycling one of these heaters on/off will cause issues, I've seen differing opinions on whether cycling between full & half power causes more wear and/or coking - can anyone clear this up? I think having enough dissipation to keep it running...

Looking at "normal" radiators, I am surprised by how low power they seem to be - for example a single panel 160x30cm radiator has an output of just 1000W with a delta T of 60°C, or have I misunderstood something? I can only (easily) fit two radiators, one 160cm long and one 100cm, which together...

Thanks, lots of useful info there! It sounds like I should be looking for passive radiators instead. I could fairly easily fit a 150-170cm long one in the saloon, and one 100cm long in the cabin, but I have no idea what I should be looking for - would standard domestic radiators work? What about...

Ok, thanks! Why not use matrix heaters, is it the noise?

Another great idea, thanks! But what about galvanic corrosion, won't that be a potential problem if using copper tube? I'm assuming that the Webasto heating surface inside the unit is made from some aluminium alloy?

Thanks, I hear you on the towel rails; I had planned to fit one in the (yet to be built) heads, but having a second one in the galley sounds like a great idea. I'm thinking of using matrix heaters for now since their small size makes them easier to fit, but long term I want to have slim/low...

Hi all, I've got a second-hand Webasto Thermo Top C which is fully working but lacks all external components (except the wiring, which thankfully is still attached). Using this I would like to get a basic heating system up & running as quickly (and cheaply) as possible, while not skimping on...

Thanks - I always thought the marine Teleflex controls originated in Gothenburg, Sweden, from a company called TX Controls. Acquired by Teleflex US in 1996. Never knew there was a UK company making these.

There's nothing wrong with it, in fact it's a really well made control - much sturdier than what you can buy new. I'm just curious, want to see if I can find documentation, parts, installation template, etc. It's missing the nut and knob for the gear disengage button, but I'm sure I can McGyver...

Hi all, This is the throttle/gear control that came fitted to my boat - can anyone help me identify the make & model? There are no markings anywhere that I can see and I haven't been able to find any pictures of the same unit; it seems to be an unusual model?

Thanks everyone, I have a better understanding now!

I see. Pretty sure mine's stainless steel. The hose connecting to it is rubber though.

Forgive my ignorance, what will measuring exhaust temperature give me that I can't already see from coolant & oil temps?

Yes please! Ideally in a way that allows both ends to be identified, and which doesn't fall off, fade, or get wiped out by fuel. Clear heatshrink tubing is great for protecting labels on cables. Virtually indestructible.

I would also recommend spending the extra £££ to buy tinned cable, and investing in a selection of glue lined heat shrink tubing, with which to cover cable joins and end terminals. Once installed, coat terminals with spray vaseline, which is very effective at preventing corrosion.
