balance

The balance of trade, commercial balance, or net exports (sometimes symbolized as NX), is the difference between the monetary value of a nation's exports and imports over a certain time period. Sometimes a distinction is made between a balance of trade for goods versus one for services. The balance of trade measures a flow of exports and imports over a given period of time. The notion of the balance of trade does not mean that exports and imports are "in balance" with each other.
If a country exports a greater value than it imports, it has a trade surplus or positive trade balance, and conversely, if a country imports a greater value than it exports, it has a trade deficit or negative trade balance. As of 2016, about 60 out of 200 countries have a trade surplus. The notion that bilateral trade deficits are bad in and of themselves is overwhelmingly rejected by trade experts and economists.

    Do you have balance hot and cold water pressure with a combi boiler?

    So getting a digital shower and it says the hot and cold water should be balanced. Am I right in thinking they should already be balanced with the hot taking on the cold pressure entering the boiler or am I way off? Cheers

    Balancing radiators in a 2 zone system

    Hey everyone, Looking advice on balancing the radiators in a 2 zone (+hot water) system. I know you should open all valves and then close the one that heats up the quickest and open again by 1/4 turn, following this pattern for the rest radiators. Is it the same process for a 2 zone system...
