Any plumbers here?

Trying to figure something out with my heating in the house.

Got an oil fired boiler out the back, fairly new one which runs the heating and hot water in the house.

On the water system I have master/main pump which appears to move the water from boiler/around the system.

Then I have two other pumps/valves which depending on whether I turn the heating on or the water on with the timer box, opens the valves depending on what I want.

Now that box where I can set the time for it to come on once, twice, constant turns the main water pump on and off, so if I have no heating or water on, the boiler isn't firing so the pump doesn't kick in and pump water around.

When I want heating or water, I flick either or both on, this starts up the pump and boiler and water circulates... I trust you are with me so far.


So now Ihave a warm house and water, I turn them timer off, which turns the boiler and pump off......but here is the problem, the master pump no longer turns off, it just sits there churning away, and the only way to turn it off now is at the plug, but the other problem is, in a month-2 month period I have used like 500 litres of oil.

This is the pump in question

Any idea as to why it isn't turning off when it should? And why I am using so much god damn oil, no idea what the boiler is, but it is a grade A efficiency boiler, next door haven't used half of what I have used, in a bigger house with a bigger family.


Would speak to landlord but the term chocolate teapot springs to mind

Sure someone isn't stealing your oil?

Heating oil theft is rife and it can be as low-tech as someone sneaking into your back garden armed with a hosepipe and a couple of jerry cans every night for a week.

Even if I left my heating on 24/7 (which I don't), I wouldn't use 500l in a month. In fact, I'd query if that was even possible.

So theft or a leak are my two starters for 10.

Could the pump be remaining on because the frost 'stat is kicking in? My outdoor boiler fires itself up and starts circulating through the heat store if the temperature inside the boiler drops below 5 degrees.

Otherwise, get a wiring diagram and chase it through. There will be a very limited number of things that will trip the relay that turns that pump on.

Possible, but it seems to be intermittent, doesn't have to be cold outside for it to do it.

Tank is locked away in barn and no way to get to it without key or making a lot of noise, and there was a new tank, new line and new boiler run....got oil on 1st October, now all gone.

It may be that the pump continues to run for a while to prevent hot spots in the boiler. It's called pump overrun I think. Is just the pump running or is the burner firing as well?

A lot of boilers have the pump overrunning when the water is above say 60 for instance. Usually controlled by a pump overrun stat, which may or may not be be faulty with any other component.

What is the make and model of the boiler - should be easy to find a manual for it.

Much easier to fault find then.

Traditionally Oil fired boilers are pretty cheap to run, one of the cheapest forms. That said, you have to think about getting the oil and plan ahead a bit.

Boiler is around the back of the house, will have to check it tomorrow (bit of a walk)

The thing is, there is no oil, so no heating, but the pump wont switch off so no hot spots.


Krad, live out on the country, it is a lot easier to get oil plumbed in and delivered as opposed to gas

Might get a boiler man out to check it all out as shit, as it is just burning through oil at a vast rate of knots

Wow Kradmelder. You really have no idea how totally and uneccessarily over-complex it has proven to be possible to make a simple device to heat water using an oil burner for the UK market.

I wouldn't have thought it was necessary to have even ONE microprocessor in such a device. It turns out that even my simple one has at least three, all of which are highly prone to failure.

If a central heating boiler (geyser/water ehating device) lasts five years without requiring a major repair, you're doing well. The water reservoir actually exploded on my dads oil fired one recently. Turns out it was made of cast iron.

In the UK a "geyser" is a very specific and now totally obsolete type of cylinder-shaped gas fired water heater. As history would dictate, almost totally indestructable although there were a few deaths due to carbon monoxide poisoning. My last house had a geyser and it never missed a beat (or went out) in 12 years. My current house has a 4 year old oil combi boiler and it's failed hard three times, each instance requiring a three figure sum or upwards of six hours of my time (which is worth a hell of a lot more) to fix it.

thought geysers fired 15 feet of shit in the air
