dual heating system. pump

    Hi,

    Was wondering if anyone can give me an answer on the following;
    I just moved into a two storey house built in approx 1986 which has a dual heating system (as far as I know), oil and solid (back boiler over open fire). My question is how do I know if the pump that circulates the water from the back boiler is on or not. Since I moved in I've been messing around with it a little trying to see which way gives more heat to rads and now I don't know if its on or off (either way made no significant difference to heat going to rads). Really can't afford to wait until I get an electric bill that is too high and then I know it was left on. Is there any way to know if the pump is on or off? The button which the previous owner told me to use has no indication as to whether its on or off.
    Apologies if this is a really stupid question. This is my first house and I know nothing about heating systems. Much less about back boilers and pumps.

    Thank you

    Put your hand on the pump & feel for vibration. It should really be powered via a pipe thermostat rather than a switch.

    I'm not exactly sure what the pump looks like...where are they usually found?

    I presume that you physically have to flick a switch to activate the pump?The easiest way to know if its on is when you flick the switch leave your hand on the circulating pump you will feel a slight vibration in the pump or alternatively when you light the fire and activate the pump the rads will heat up. However if the pump is not working extinguish the fire and DO NOT use the back boiler until you get it replaced.IF you are unsure about it I would advise you to ask a plumber to call and inspect it for you.As for the ESB bill even if you left the pump on it wouldn't really have much of a negative impact on your bill
