Supposedly a big part of the issue K & Sovrmennys have had is complex manual control & inexperienced/low motivation operators -> electronic control would help keep stuff burning optimally.
I think it would be the foolest thing not to put ALL 8 new boilers. Boiler KVG-3 has lifespan of some 100.000 hours and that is some 11 years of non-stop heating. Problem is that in 90s Russians did not use proper purified water - they often used simple potable water as boiler water, and these boilers are very sensitive to any impurity and residues. Also, they need very skilfull complement to operate them, especially when often changing steaming conditions. All that Russians lacked in 90s.
