Why does my cats breath smell of cat food ?

Not according to my conversations. I’ll ask again when the ‘salty box of clever goo’ company reemerges with their hangovers

Nope. A slow pump pumping into a free running circuit will have a high flow rate. When you put the HW on, the cylinder thermostat constantly opens and closes the zone valve that controls the tank temp thus changing the resistance of flow that the ASHP sees whilst heating is also running. Those ‘peaks and troughs’ cause irregularity and the usually quite sensitive flow switch can easily take a dislike to that. The buffer tanks are used to hydraulically separate the ASHP from the rest of the system, so auxiliary pumps etc have zero effect on the primary ASHP circuit / pump / flow switches etc. They also give a draw down volume of stored warm water that the ASHP can use to help defeat defrosting. I’d bet a well positioned primary bypass valve would sort this out without reinventing the wheel

I quite like the system that underslings the beams as well as infills and covers them. I assume it also means less insulation has to go on top if you get some underneath.

Edge-of-your-seat shit, this.

“Operation cliffhanger” is in full effect.

Did they consult you when they made the first ducks arse, Dave ? Seriously though, I may be on to something. ?

Quick fix first, long term fix once proven I expect.

I’m fitting a battery system shortly and will update on a relevant thread as to results / price / RoI etc and practicalities. One Achilles heel has been the naff 3kW throughput from most generic battery inverters, but yours truly has made a very interesting breakthrough in that dept. ? I think one particular battery system may well be ‘ready to rock’ in terms of price and practicality. Now only if I could find a guinea pig willing for me to fit it for so I can test my theory ????

There looking into a slimline, DIN rail mounted one. I think I’ll start routinely fitting the kWh registers / meters that @JSHarris and @Barney12 have, as I’ve seen them in action at @Barney12‘s and they’re A1 for “customer confidence” measures. I shall also adopt the neon ‘heater on’ indicator as that’s a good reference between power being on, contactor being on and energy being consumed. If the indicator is on, but no energy is being consumed, then you know the immersion stat has popped or the immersion has failed. Cheap, simple and effective measures, and the meters will give you the “grin factor” as you’ll be able to quantify what the SA unit has ‘earned’ you in stores excess energy. The fog is lifting. ?

One of our chosen lines of keeping threads informative is to only reference information wherever practicable. Linking to such information is of further benefit to the post / thread. Stating ones own opinion as if it were fact, requires said facts to back it up. Lets please keep it factual, AND informative please Mods.

Went for a jalfrezi last night. That hasn’t helped. ?

We are the fleas on the dog.

Just a few pics then Need half hour to look through those Great progress,

QS told me to cut up the PB and lose it in all the internal stud walls. I thought he was a cock at first, but the more you think about it, and after @JSHarris identified that it has high thermal ‘capacity’, it makes a good bit of sense perhaps.

All of the above...... And a few bits more most probably Welcome aboard !

Drinks are on you then ? ?

Thread edited and tidied. The management ?

You don’t do things by halves, do you!?!? Looks really good.

Prices etc can be followed here ?

If you have 165mm then you could go for 120mm of PIR and then a 30mm insulated UFH overlay system if you’d prefer to go down that route. Link Then top it with 18mm P5

That’s a mouthful in more than one way ?

That’s racist We call them noggins too boyo.

There’s a first time for everything Dave

Anything in here?
