Oil usage clock

Wearb

I read here some time ago about hooking a clock up to oil burner to record running hours. Do any of you know of a suitable clock for this purpose? It is needed to record approx usage in a rental property.

Not very accurate unless fitted on the power supply between thermostat and burner.
Oil meter from bes.co.uk better

Thanks scudo. That is where it would be wired to. Do you know of any clock that would count up the hours like needed in such a case.

I've often seen them, can't remember brand, but they look simple, ask in electrical shop, their a small digital solid number display.
(not a electronic screen) if that helps.

I've seen the also fitted on power supply to boiler which will give wrong reading of burner running time.

Fitted by more esserentic people than myself !!!!

Perhaps Hobbs ( now part of Honeywell) 20029/20036 might be suitable. Stewart Warner is another with a range of measuring instruments, although more known in automotive.
Hope this helps.

Cheapest option will be a mechanical time clock unit from somewhere like radionics,

http://ie.rs-online.com/web/p/hours-run-meters/2971055/

it gets wired to the live and neutral after the thermostat before the burner, and gives a very accurate run time for the burner, if it's oil, multiply that by the nozzle hourly burn rate, and you're pretty close to the usage.

Fitted one here years ago, the burner clock has something like 11,000 hours on it at this stage. I also have one on the pump, and that's showing that my burner to pump time is about 2 to 1,

Very easy to do, just needs a small box to mount it on the wall near the boiler (if the boiler is in a separate boiler room, or it's small enough to fit inside the casing, and with mechanical, there's no need for any battery or backup power unit.

I've used these for some years, posted some time go, they work very well at a fraction of the cost of a meter, the one I get from RS comes with a fixing box.

The link to Radionics provides exactly what I am looking for.
Thanks

I had one fitted last January. i found it great for working out how much i have been using.

the proper oil meters, are up on nearly 300 euro
there are differnt types
u need one with a metering range of up to 8 litres per hour
they are tiny inside, they need to be to be accurate, thats why they are expensive

Wearb

In case anybody is interested, here is the sort of data that can be gotten from installing one of these counters. btw the figures in the top RH corner are running totals of litres used and costs.




Cost per hour column is wrong, the rest look OK. I will work on it and see if I can get it right, though that column isn't very important, as the "% time burner run" gives similar information.

Got it corrected and replaced the image above.
