return

In finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows (or securities, or other investments) which the investor receives from that investment, such as interest payments, coupons, cash dividends, stock dividends or the payoff from a derivative or structured product. It may be measured either in absolute terms (e.g., dollars) or as a percentage of the amount invested. The latter is also called the holding period return.
A loss instead of a profit is described as a negative return, assuming the amount invested is greater than zero.
To compare returns over time periods of different lengths on an equal basis, it is useful to convert each return into a return over a period of time of a standard length. The result of the conversion is called the rate of return.Typically, the period of time is a year, in which case the rate of return is also called the annualized return, and the conversion process, described below, is called annualization.
The return on investment (ROI) is return per dollar invested. It is a measure of investment performance, as opposed to size (c.f. return on equity, return on assets, return on capital employed).

    Using plastic pipe on flow and return

    I have to move a hot water storage cylinder to a new location. The new location is somewhat further from the boiler and the route is trickier. To that end I have considered using 22mm plastic pipe for the flow and return, it should have less thermal loss and be considerably easier to route...

    Hot water secondary return - plastic pipe?

    A quick question on secondary returns for HW. I remember reading somewhere that you cannot use Hep2o for a secondary return. Could someone explain why? I was thinking about this the other day, and central heating circuits are fine with Hep2o, so why not HW circuits? Surely both pump hot water...

    Secondary return insulation

    Over a year ago a good local plumber installed for me (the householder) a new Grant Vortex Eco Utility 26 35 boiler, but ended the job (for which I paid his firm in full) and left the area without first pricing/fitting the secondary return that I had requested. A different - OFTEC-registered -...

    Strange setup

    Since my in-laws boiler was replaced they have been having a number of issues, such as poor radiator temp and rads on with hw, to name a couple. The company has been out multiple 6+ times and tbh sounds like they are clutching at straws, especially as it worked before the replacement and now...

    Does the placement of the injector tee look correct?

    You can see the flow from the stove top middle and the return to the stove continues about a foot just behind the fridge and then turns back into the wall and stove just behind. Thanks

    Piping up heating system

    When piping up a heating system do you pay much attention to which side of the rad. you take the flow and return to. As to say if you were fitting trvs on the left of the rad you'd take flow to the left side of every rad. Or just get a flow and return to every rad and don't bother about which...
