It is not easy to rid old urban houses from municipal heating supply networks
but why connect new developments to them? Still thinking of constructing new
underground pipelines? They waste half the amount of energy on its way
to customers. The idea to transport fuel instead of heat is far more rational.
A single INTERBLOCK compact modular boiler room of new series provides 97%
of thermal efficiency and is quite sufficient to heat a multistory building. It can
be installed either outdoors or indoors because a smoke stack is unnecessary.

Even individual in-house gas heaters are not needed now as they are
far more expensive. A boiler room with a built-in INTERBLOCK steam
generator provides the cost of 1 Gcal below 800 Russian roubles.
It is difficult to imagine the amount of savings!
