Ruila basic school

One of our firsts industrial burners, the old model of PV350 was installed in 2009 to heat the school and the gym. They wanted to keep the option for logwood heating, so the boiler got 2 doors. Later, in 2018 the logwood door got a new burner PV180 and the PV350 retired, it has not been used since then, even though this option still exists.
