Tony, that's an interesting comment. What gets changed for marine standards? My attention was drawn to the CO2 measurements which is not something I've ever taken notice off with previous Air heaters or the current water heater. I am guessing it's set and forget but I wonder if it actually makes much difference? Cheers,

Interesting that it's fixed on newer models. My current sailboat, and the new NB will be 24v and therefore the heater gets it's 12v from a converter which means the voltage is rock solid regardless. Boat is also having lithium (again got them already, and once you've had it it's hard to go back to LA!). Cheers Many thanks, looks very interesting but a DIY step too far for this build I think. I'll look up the parts and info you mention though as I've not come across this before. When I've done my NB build I plan on converting my van into a camper so this could be the ticket on there Cheers

Thanks, I rather hope NMEA does come on, I've read their (his/her?) posts and they seem very knowledgeable. I don't understand a 'pressure jet boiler' but I've have a google and see. The heat exchanger is https://www.butlertechnik.com/installation-accessories-c63/webasto-motor-home-plate-heat-exchanger-with-mixer-valve-4111209a-p1516 - I have one on the sail boat. It's fabulous, within ten minutes (top c) you get unlimited amounts of hot water, bit like a combi boiler. Obviously the tank water is also getting heated.

Hi, Choosing a water heater for my 60' Sailaway NB. I've got a Thermo Top C on a sail boat currently which does a fine job but only heats water in an exchanger and the Calorifier. My questions are does anyone vote for Eberspacher over Webasto and if so why please? Assuming Webasto I'm struggling to see the benefits of the 'new' Evo 5 over the (I'm led to believe) discontinued Top C? Can anyone shed any light? I've read some stuff on the CO2 adjustment. Is that likely to be necessary? It's not something I've ever touched on the sailboat. Anything else I should consider, for 4 or 5 rads, heat exchanger then calorifier circuit? For ease I am thinking of buying a 'narrowboat kit' which seems to include most of the bits I'll need. I don't like Webasto's filter but it sounds like they are mandating their dealers to fit them now so I guess that's necessary. thanks, Malc

I’m not sure if this will work... but is it possible to revive this thread from a while back. I’m considering thermal break against double glazed on a new build. Does anyone else have any direct experience of the benefits of thermal break? My builder is sceptical and seems to think that there will still be condensation thought he doesn’t have direct experience. thanks
