Webasto thermo top C

Has anybody had experience with these? Are they any good? Will they produce enough hot water to heat a 30ft boat and water in a calorifier?

Thanks

I recall that there are 2 different outputs 4 and 5kw (??) Plenty for a 30 footer but you may have problems in the coldest weather fully heating all cabin areas at the same time.

No, only one output max for the TTC which is 5kw, the 4kw max is the TTE, for a 30 foot boat it is quite adequate, I have fitted lots of them and they are excellent units, if you design the water system right and use a pressure vessel instead of a header tank it will perform better. Try to use rads if possible as matrix are not the best performers. I have the full marine install manual if you want a copy, it has chapter and verse on plumbing options as well as just fitting the unit.

5kW unit works a treat in my 32ft Hunter and the ability to have hot water without running the engine is a big plus when on a mooring or anchored.
The calorifier only affects heat output to the radiators until water hot - about half an hour. If this were a problem, I could close off feed to calorifier
but I've never bothered.
Would I change to a warm air system - no chance!

Also forgot to say, but you've picked the right time, the price of Marine / RV kits have just had a substantial price reduction to bring them a bit more in line with vehicle kits.

Little Ship has the thermo top fitted with the ability to heat water on it's own or with heating. Make sure that it is correctly installed.

Thanks, looks like I'll go for it, then! Would definitely be interested in the Manual.

Thermo Top C

Im just about to embark on such an installation and having trouble deciding where to locate the header tank I note you suggest the unit works better with a pressure vessel and radiators so will have another look at what I was originally planning. I must admit that I only have basic installation info from the Webasto website which isn't much help. I would greatly appreciate a copy of the marine install manual if this is possible. I also read that its not a good idea to tap into the existing plastic fuel tank, I assume because of the swarf, so Im also thinking of installing a seperate fuel tank does anyone have any thoughts on this please.
