Hello, I would need an advice about a water heater and I hope you could give me a good advice.
I would prefer to have a tankless water heater (instantaneous).
The electrical wire is 10 mm2 and (if I am using the correct terms) the fuse is 40A. I found 2 water heaters (9 kW and 12 kW) and their manufacturer says that were designed for single phase, but the electrician counters that the electrical installation is too weak to power any of those water heaters.
Can anyone confirm if this is true ? Does anyone has triple phase electricity (380V) ? They told me that it's impossible to have it :-(
And the other option is to install a bulky tank water heater. I made a really serious research and I found that the best brands in the world are Rheem and Rinnai and the best european brands are Fagor and Electrolux. However I am unable to find any of those brands and I am only being offered crappy brands like tesy (very low quality made in Bulgaria, on some forums they write how properties were flooded and people were burn or got electric shocks) and Atlantic (produced in Egypt, without need to further talk about the "quality").
In the end, if you can not give me an advice, I would at least be very happy to hear your experience (what to you have and what is the lifespan of that product). Many thanks in advance!
