There is no simple answer to this question as the best type of radiator depends on a number of factors, including the size and layout of your home, the climate you live in, and your personal preferences. That said, here are some general guidelines to help you choose the right type of radiator for your home. If you live in a climate with moderate temperatures and want to evenly heat your home, a two-row radiator may be the best option. Two-row radiators are also a good choice if you have limited wall space or if you want to free up floor space by mounting your radiator on the wall. If you live in a colder climate or want to heat your home more quickly, a three-row radiator may be a better option. Three-row radiators provide more heat output than two-row radiators and can do so at lower water temperatures, making them more efficient. However, they can also be more expensive, so it's important to weigh all your options before making a decision.
