so shower, toilet, washbasin, tiles with connections etc. are already 5000€, quite okay so far. Underfloor heating is too expensive as a separate price. Network is 100€ each, rather cheap.
It seems to me that everything is IMHO OK except for the additional cost for the underfloor heating. What would be an appropriate additional cost for the underfloor heating? How many thermostats are ideally needed? Do developers even leave room for negotiation and what is the recommended strategy here?
oh dear my developer wants 160€ per thermostat... this will be expensive :-(
is the price OK?
What kind of things are those for 160€? Display, sensors...etc??
We have the thermostats electrically pre-installed but initially none installed - no idea if we really save anything there ;-) it is an option for sluggish systems with low flow temperature (keyword "self-regulating effect")
