### Boilers in France: Regulations, Maintenance, Repair

Nov 29, 2018· The electric boiler. In France, electric boilers are mainly found in rented apartments or houses, as it is a fairly cheap heating method for the landlord to purchase. This said, electricity is currently one of the most expensive energy types in France, so in the cases of a high consumption, electricity bills can quickly skyrocket.

Disadvantages of shell boilers: The package principle means that approximately 27 000 kg/h is the maximum output of a shell boiler. If more steam is required, then several boilers need to be connected together. The large diameter cylinders used in the construction of shell boilers effectively limit their operating pressure to approximately 27 bar.

A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler’s full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to
