Excessive kerosene consumption?

Stallingrad

Just went through 500l of Kero in 4 weeks. 2300sq ft house (2006), well insulated with underfloor. We would usually get closer to 6-7 weeks during winter from 500l.

Just wondering how other people got on during the last month?

I have had a few service calls due to the same concerns. There has been excessive usage recently, though a poorly adjusted boiler doesn't help.

I was beginning to think our kerosene was being stolen...We have an uninsulated old house, 1800 square feet. Barely had the heating on in January and February and was going through 400l a month, for just 3-4 hours a day max. Since turned the thermostat way down and am using much less now. The house is really cold even when the heating is on so was mainly just trying to make sure the pipes didn’t freeze.

There is something major wrong if your burning 13 litres per day and the boiler only on between 3 to 4 hours per day max

I wouldn't think its totally over the top.

A bad or out of tune boiler would easily burn 3.5 ltr an hour.
We don't know what size nozzle or boiler, an old version pre 2003 firebird 120 on a. 75 nozzle would easily drink that on a good day in a bad house.

When I do the maths with customers, I normally say 2.5 ltr per hour for good boiler and 3.5 for bad.
Its not scientific I know, but not far off.
+ customer's who only use boiler for the odd hour use more on average as its running full throttle for the first 3/4 hour just getting up to temperature

Just my own experience talking. ��

I don't know exactly tom but the heat transfer time is greatly reduced

at a guess I would say 15/20%

probably be better if I got somebody to service the boiler as well :o
