The basic premise of the design was a single circuit running above dew point to take the edge off heatwaves. (Downstairs with the UFH that’s working a treat already). We took an active decision not to go for aircon type cooling. We don’t want wet floors so if we encompassed significant condensation on the fancoil(s) then that means a second circuit and a volumiser and, and, and…. And whilst that may be needed that’s not our first choice. We want to keep it simple, and if my arithmetic is correct we only need a little cooling. One odd aside, we’ve found that we can sleep comfortably with the MVHR induced lower humidity at higher temperatures than we could have done in our old naturally aspirated house. I’ve nicknamed the Zehnder “Life Support” but perhaps I should call it Turbo.

I’m too much of a whimp. I looked at one from Germany and apart from the unknown of import duties (thank you so much Brexit) the possible grief of maintenance worried me off of the idea. I would prefer to have a uk distributor who hopefully will carry spares for a good few years. I can dream.

Well done Nick. Will investigate.

I thought that. When I contacted them they clarified that it’s only the concealed (i.e. naked) units that can be hung from a ceiling. The briza units are a lot more attractive.

Our concern with recessed ceiling units was that we didn’t want to build in the need for loft access for maintenance. I’m creaky enough as it is let alone in 15 years time as I approach my 9th decade!

Brilliant. Thank you. I have googled and googled fan coils, fan convectors, hydronic terminals, heat pump convectors, and many other combinations and not seen them. I've had a look at their website, and it appears exactly what we need. I’ve had the same conversation repeatedly, and been met with confusion when I’ve tried to explain what we are trying to do. These guys appear to have already got it. @nikotime who are you getting a quote from?

If you think Welsh Nick is going to replace me as tea boy and cleaner you’ve got another thing coming. I’ve got a talent and I’m going to use it! One lump or two?

I know who is to blame. Little, round, bald guy with a dodgy sense of humour. He got lumbered with the labels of Principal Designer and Principal Contractor but his real talent was as Head of Global Operations for On Site Catering and Sweeping. Humph. One tries….

It was, and I identified the unit I intended to buy. Just not available. Sigh. I’ll get there.

Yes, hung from a ceiling; to do cooling and no condensate drain, plan to run above dew point

We need a fan coil, in our bedroom. It was always part of the plan, so we have ‘lecky and pipes laid ready, but I can’t find one. I know that sounds dumb and maybe I am missing something obvious. But I can’t find one. So I need help. The brief: a 2 pipe fan coil which can be hung from a ceiling. Needs to be less than a meter wide. I identified the Myson iVector 2, which may have been perfect, but that’s not available, and they can’t even predict when it will be. And I simply can’t find an alternative. Help!

I will do if the technical guys don’t sort it. We’ll live with a bit of condensation on our manifold for now, and I’ll find time sometime to store the manual.

It is a setup issue and I’ve had some input from Maxa technical and am seeking more. We have a Maxa heat pump, single zone, UFH only at present, no volumisers or any other unnecessary gubbins. We won’t be getting into the realms of damp floors. But what does “latch on” mean?

I think it’s my turn to ask a dumb question. (When one has a talent one should use it!). What’s is the issue with condensation? I get that condensation on a tiled floor would not be good. I’m not trying to cool the floor that much. I also get that condensation on a concealed pipe would not be good, rotting the timber nearby. We are seeing condensation on our manifold when I run the ASHP at too cool a flow temp. (OK there’s another question there but our heat pump is doing odd stuff, appearing unwilling to ‘get out of bed’ for flow temps above f cold, so cooling needs to be in ‘hard’ bursts, but that’s another question). So we run our heat pump, have a nice coolish slab, get condensation on the manifold, so what? It’s all stainless and brass and plastic, I can put a towel under it to catch the drips, so where’s the harm short term? One day, I’ll have fitted a fan coil upstairs (having major issues finding a ceiling mounted one), and the heat pump control will be sorted so it does moderate cooling so we’ll avoid condensation that way and I can box in the manifold safe in the knowledge that it’s not dripping. But for now I need to burst cool the slab as that’s what the heat pump wants to do, so is it ok to accept condensation on an exposed manifold during a heatwave?

Ours too, but as suggested above depends how you buy. We have sourced the majority of things.
