Biral MX 12-1 blocked replaced by electronic circulator Biral AX 25-4 180 RED

A few days ago I wanted to restart my heating circuit ...

The 14-year-old Biral circulator was blocked from blocked ...

It's funny because the other years he started without worries after the summer break (about 7 months). I probably had to unlock it with the screw once or twice over the 2 years ... I mean that compared to other brands, this old classic Biral was blocked much less ... Until today ' hui where it is the disaster.

It was so blocked that the rotor shell remained on the frame ... I had to dismantle dozens of circulators in my life and I had never seen this ...

I tried to loosen it with WD40, I managed with difficulty after 10 injections of WD40 to make it run empty (spinning hull but no more, too much friction between the hull and the rotor ...) ... In other words: he died at home dead ...

As a good chief econologist, I went to see my favorite plumber, hoping to be able to buy the turbine + shell ... obviously impossible to replace only the turbine and the shell ...

He advised me of an electronic model from the same brand which (according to him) no longer jams even after extended periods of downtime. To see ... in 1 year : Mrgreen:

In any case, they have made a lot of progress on engine efficiency (and perhaps the turbines ... but we have been in control for years ... it seemed to me ???) because I go from an average consumption of 40W to 15W ... see less because the electronics regulate and I saw a consumption of 11W this morning ... : Shock: : Shock: : Shock:

It has not been running for 24 hours so to see in use!

To see if it will last 14 years also at the rate of 5 months a year ...

In terms of price, the Biral MX 12-1 is still around € 120 and I paid its little electronic brother € 165 ...

By saving 30W per h at 0.15 € per kWh, the 45 € are paid for in 45 / (30 * 0.00015) = 10 h ... or 000 days in continuous operation ...

Suffice to say that it is completely stupid to continue to install classic circulators ... but the electronics must last as many years as the classics : Mrgreen:
