G and J

Apart from aesthetics I don’t think there is a difference. Many, maybe most FCUs are specced for running below dew point. I am guessing that cooling levels will be about a third at 15°C compared with 7°C flow temp for a room temp of 23°C. Some FCU companies are now publishing 16°C flow temp cooling data, which is kinda handy. I wouldn’t call it fake air con, all these systems have the same components, but it is limited by the desire to avoid condensation. Perhaps we should call it airconlite. But your point about capacity is well made. The best FCU I can find will deliver circa 800W of cooling at 15°C flow temp. These unit’s are about 1.3 x the size of the 1.7kW Panasonic monoblock a2a. So the base plan was to have two FCUs upstairs, and they’d be installed already I’d we hadn’t hit the rocks when trying to buy them. But the more I look at it the better the Panasonic thingy looks. But can I install it myself and still have a warranty…..

Unlikely to keep going overnight, and the other consideration as also dries the air (which has an impact on comfort) likely not to need it working so hard as fan coil which helps balance out noise

The Panasonic one you referenced is a wall mounted also Good spot......we piped for ceiling mounted on internal wall. Can't (or possibly more accurately don't want to) sensibly get pipes anywhere else for wall mounting. This unit would go discretely in a different place.

Literally down the road. Limited info but look to be wall mounted (we're looking for ceiling) and again size vs output for cooling isn't as 'good'. We would really have prefered the fan coil route (our ufh cooling has been great), but there is also a question of future proofing...we don't want to cool below dew point, but in balmy Suffolk are the fan coils going to be enough? Also 'investing' in appropriate blind for large west (ish) window, which will be great in the shoulder seasons, but in a heatwave not so great. The things that you only find out when you move in, despite meticulous planning!

Looking at website now!

Getting specs to make sure they are going to work in the way we want....size of units vs effectiveness....ability to locate where we want them. Spilt system is not an option we want to take, mostly due to the limitation of our plot and also for harmonious relations with our neighbours. Downsides all relevant and need to be factored in, but sleep deprivation is real!

We're struggling to get an upstairs fan coil solution (which was the original plan and piped for) that we're comfortable with, but in the intervening period since we've moved in (heatwaves etc) we're wondering if we should just go for a stand alone air conditioning unit. Panasonic do a good looking r290 unit (solo) of the right spec, which looks straight forward enough to fit (annoying that it will be retro fit but there you go...) but 1. Is diy installation an reasonable option? and 2. One supplier claims that unless professionally installed the warranty is invalid. Accurate or likely to be part of the sales pitch? Views appreciated.

Because that’s an additional plate that you’ll have spinning, detracting from what should be getting 100% of your attention. Nothing to do with dust, simply all about zero distraction +1 to this......it makes it feel as if your'e not achieving much in the short term, but ......

Can't find the post quickly but @saveasteading suggested being on site as much as possible when people are there, even if you are just tidying, making tea etc, (but doing something) goes a very long way to building the relationship, as well as seeing what's happening. Difficult if you are not able to do that, even for a short while each day, as once it's happened and your seeing it after the event, it gives the resulting discussion more potential for getting fraught.

Dunno but the amount the cost of slate was reduced by was equivalent to quite a happy proportion of the cost of the solar system.

You can buy a one way valve that you can pop in and it stops rats. Amazon sells a good quality Rosshield one. And yes, they can swim.

I knew there’d be a downside to insulation lol

Boils my brain to try and get a feel for it, but I think there may be a 5D graph possible showing payback period vs panel capacity, orientation, inverter capacity and battery capacity. For us and I assume many, maxing the panels on one face of the roof was a no brainer as it saved slate (I’m not a fan of surface mount panels). From that our installer used a sort of rule of thumb/wet finger analysis to give us an inverter/battery pair he’d used loads of times on our sort of size if installation and which was well priced. So the 5D graph and all the AI advanced modelling wasn’t needed. So no deep thinking needed. Simples.

And I thought I needed to get out more lol
