Are special request prices reasonable?

I cannot give you individual prices for our thermostats. They were included as a package in the heating trade. Therefore, I cannot comment on your prices, sorry. However, it would be interesting to know exactly what the standard includes and what the upgrade looks like. What does the [Bauleistungsbeschreibung] say about this?

Standard features completely normal radiators with a gas condensing boiler.

Hello Hello

the surcharge already depends on various factors
room sizes, layouts, requirements for insulation.......

It is already difficult to make a statement, but I think with 15 - 25 €
something like that is feasible.

: do you mean with 15-25€ the reasonable surcharge for underfloor heating or thermostat?
