boilers in Europe have a working pressure of 1 to 2bar Safeti valves are 2.5 bar a maximum working pressure for vigas is 3 bar
it is not so bad in Portugal, fuel prices are the same I only work for half the price of an hour
in Europe are mostly systems under pressure and we do not use auto fill because there is no need for this
Unfortunately,all factory boilers in Europe think that all have water supply through a network Unfortunately this is not true
coil is connected to a water supply network with the valve http://products.ecc.emea.honeywell.com/europe/ecatdata/pg_ts130.html
in my area, most of the systems are under pressure Only very old systems have open expansion on the highest point of the sistem
cooling loop in the EU is a legal norm for boilers under pressure
what type of furnace you own certainly is all described in the instructions
the forced cooling coil in the event of overheating is connected to the water supply network
