Its looking more like a home!
Only fly in the ointment is being let down by the Plumbers who appear when they feel like it and blame deliveries of their kit, despite knowing about this job for 6 months !
Anyway will try to stay calm, for now !

Looking great Russ. Completely hear you on the plumbers, the number of times I've had trades that turn up for a couple of days then go off to another job for a few days then come back for a day etc. Drives me bonkers  banghead

Guys, now looking for a bit of advice.
As mentioned there has been a delay in getting the UFH on to dry the floor out so need some advice as to what temperature we should be putting into the floor to save overheating and cracking the concrete.

The 100mm thick floor was laid on 21st Feb and the kit went up about a month later. At the moment the Moisture Content reads about 17% which is obviously too high to lay the floor yet but now the temporary boiler is working (at last!) what sort of temperature should I be aiming for ?

I read somewhere to start at 20 deg raising by 5 deg avery 3 days or so ??

Is that reasonable ?

thanks in anticipation !

Heat alone won't do it. Yes start at a low temperature and don't go too mad - gently does it bring the temp up slowly,  but I would suggest you also need to get a couple of "air movers" in. The moving air helps the moisture evaporate and also pushes the moist air out of the building (ventilation). It will really speed up the drying. The down side is they are quite noisy.  This is the sort of thing - a normal fan is not so good, these are designed to move lots of air at floor level.

(you can buy or hire them).

A few years back our washing machine dumped lots of water (glass came out of the door and it was dumping cold water for 6 hours) into the ground floor of our bungalow. UFH in a screed. Water crept the whole length of the house so all of the screed was wet - really wet. Took 4 weeks to get the moisture content back down - combination of UFH on and 3 of these air movers - this was advised by a company specialising in drying out flooded properties. Fortunately for us the insurance company sorted it all out. You could see the immediate effect of the air movers. We kept moving them around to ensure all areas were covered.

Cheers Roger, assume windows would need to be cracked open as well ?

Yes, if possible windows and doors open as much as possible to get as much air moving as you can. We were lucky in the sense that it was mid summer and warm, dry and sunny when we were flooded, so could open everything up. Not sure what the weather is like where you are but some parts of the country have been very cold and wet!

100mm=100 days to dry.

Best to let the slab warm up slowly too, to avoid cracking, can't recall the info I was given when we commissioned

I seem to remember reading somewhere about raising the temp into the slab by 1c / day

Are you using ASHP with the UFH?

Some (Panasonic?) come with a dry concrete program that gradually increases the heat to dry the screed

We will be, its a Mitsubishi 5kW Ecodan, at the moment, because of delivery delays, we have a temporary Electric Boiler to start warming the floor up until the ASHP arrives middle of next week.

run the circulation pump with the heater off, check the water temperature and report back here

all the numbers/advice you'll find is really just rule of thumb, there's too many variables to give a real answer

the real thing you need to watch is the floor temp vs air temp, the hotter the floor is compared to the air the faster it will dry.... but the faster it dries the more it moves/shrinks/cracks etc.

raising it 1'C per day is good advice, but don't go too far over ambient air temperature - personally I'd stop at 5'C over day time ambient

if you can leave the doors/windows wide open during the day and just crack the windows open overnight

nice slow/steady drying is best

Another exciting update !   surrender

PV & Powerwall2 are fully commissioned now and kitchen & bathroom just about finished, front room and rest of house all wired up now and so all we need done is the finishings, kitchen & bathroom finished (plumbing) and then the Engineered Oak Floor gets laid so we are aiming to move in pithing 3-4 weeks. ASHP is also running and will just need tying into the Thermostats.

Only hurdle will be the completion cert with regards to the bloody ramp to the front door !

Anyway the plan is all the joinery work completed this week, next week sparky and plumbers fit thermostats next week and then we are nearly there !

If you don't want a ramp just put a loose wooden one in and then remove it after its been signed off.
