My thinking of how a narrowboat should be is that an MHRV is essential equipment for live-aboard, but it brings one large question (below) for the BSS. What does it do? Mechanical = fans: Suck out the warm, stale, humid air... from the kitchen / shower. Suck in cold, fresh, dry air from outside, and try to do this in a balanced way so you're not pressurising the place. Heat Recovery (also Energy Recovery in hot places with aircon) = put a heat exchanger in with these fans: Use the outgoing air to warm up the incoming air. There are filters on both inputs to the heat exchanger, else it will clog up. Ventilation: send fresh and warm air to the opposite end of the boat. Heat recovery is never 100% efficient but can produce great savings. It also isn't useful as a heat source - you still need a heater somewhere. The heat recovery is also not meaningful or useful if there is no heating. Any MHRV is undermined by draughts, so houses with it fitted tend to be pretty much air-tight - let me know if you want a link to some youtube guys taking that to extremes. This is in the context of a live-aboard boat which will get some heavy-handed refitting after I find it. It will be a huge project, please wish me luck! My question is "Will having active ventilation remove the need for passive ventilation (ie. holes everywhere), which are normally required for BSS?" Or if it doesn't by itself, what else would need adding? If it has LPG / fuel gas on board I'll be removing that as soon as I have an alternative. I don't like it, it's too boomy for me. Solid fuel burning will be needed, but I want a balanced flue not a front-feed stove. That's a story for another day, but I also dislike having a potential carbon monoxide source in my box. I'm relying on the boat having plenty of electricity, which is also a story for another day. MHRVs last popped up in these old posts - Any thoughts appreciated!

HI, I'm trying to work out the kilowatt input rating for a paloma water heater. Unfortunately it's out of the boat so I don't have the plate to hand immediately... but... it's one of the 'old looking' ones with the red stripe on the front and paloma in shiny metal. White enamelled. I've found a manual which suggests it might be 635 btu/minute, which I think converts to 11kw. But that sound like rather a lot. Does anyone know what the 'normal' old school boat paloma takes in kw? Trying to work out how many vents I need to install in the re-fit! Cheers, Patrick

Hi All, Last year we had a lovely bedroom installed under our tug deck but as winter has drawn in we are starting to see signs of mould. A quick spray of vinegar/remover does the trick but I think it's time to accept we need some proper ventilation in there / also concerned about upcoming BSS. The carpenter who installed the bedroom suggested a mushroom vent on the deck, but we feel it would ruin the aesthetic and would be a tripping hazard, another suggestion was to put vents in the gunwales, but i'm concerned this could be a problem when we cruise the Thames in the summer. I'm thinking that we could cut some holes in the sides of the hatch that used to provide access to the hold. Wondering if anyone has any other suggestions or solutions. I can post some photos if it would help. Thanks, Ed

Hi everyone, Can anyone recommend a good, well-designed ventilation fan for a bathroom that works both on solar and battery back up? Are solar fans powerful enough, do you think? Or would it be better to get a fan that connects to the 12v system? If so, any suggestions for this also? Thanks, everyone, for your advice. Alan

The windows in my narrowboat are in need of replacement, if only because a previous owner removed all the opening sections! Whilst this means the boat is secure(?) it has the downside of meaning very little ventilation which on the few hot days we get becomes quite "interesting". Sadly (especially now I am retired) the budget is limited and the cost of new windows look prohibitive, so I am looking for suggestions for acquisition of good second hand windows. I can't help wondering what happens to the windows removed when boats are being refurbished ...........
