Tiling new extension and kitchen

[Dan]

As above, nurture it to it's max, around 25 degrees, then nurture it back down. It'll be fine after that and all cured and used to the heat.

Thanks All, Just not sure how to do this with the controls I have, The room stat wont do it as it wont control floor water temp just overall room temp.
Wondering if the manifold mixer will allow?

You should be able to control water temp at the manifold , which will stop the water temp from spiking ,

You can still do it with the room stat if you can lock the temperature at each increase in temperature, the stats should be working in conjunction with the boiler and you can still commission that way , i do it on all piped heated floors.

The trouble with doing it with room stats is the floor/water can reach a temperature that is higher than the air temperature in the room before it turns of , so the actual floor temperature can spike , some room stats have floor probes but in my experience with wet ufh it only tends to be bathrooms .

If it's an incremental degree each time on the room stat, it shouldnt let much hot water through each time. It'll just keep topping up the system with a burst of hot water which should be pumped evenly quite quick.

.... Is the way I understood it.

Needs to be controlled at the manifold. You must be able to lower/set flow temp there. Lowest setting is 28 deg normally. Set wall at 18 deg and control the flow temp over many days. Check floor and flow temp with a laser temp probe morning and evening.

Working on room stat only could be fatal, and I wouldn't recommend it at all.

I'll have a look at the manifold tonight and see what I've got.
Do tiles need to be grouted before this is done?

Ideally yes. Floor surface temp needs to be 18 deg or below when grouting. Best to get it grouted and wait 7 days and the turn on ufh and ramp up slowly using flow controlled temp

Any idea how much floor I should attempt to grout at a time as an amateur. Tiles are smooth but non slip finish so may not wipe up like a glazed tile. I dont want to do too much then find it's set too hard to clean up easily. But at the same time obviously want to get it done asap and not spend all day washing out buckets and paddles etc
Any recommendations on grout guessing flexible and will need to be grey coloured I think, but are any makes better than others _ anything to steer clear of?

Thanks
