Hi,
We had LPG heating installed at the end of October and I was led to believe that 4 bottles would last probably 2 - 3 months of used moderately. We are pretty tight with our heating usage and the thermostat is usually say to around 16 or 17 c when we're home, occasionally going up to 18 if it's particularly cold outside. Heating is off at night and when we're out.
We've been pretty horrified by our gas usage since it's been installed and we're wondering if there are some issues.
According to info online, mains gas is about 8p a unit, and LPG should be about 13p a unit, so I was expecting LPG to workout about 2/3 more expensive than what we were paying for mains at our old house, which was about £60-70 a month in winter.
When we had a bit of a cold snap at the end of Nov, early December, we got through 2 bottles (£150) in two and a half weeks! We used 3 and a bit bottles in around a month (£300). This is vastly more expensive than mains gas, even taking in the expected difference based on the unit price.
The thing that concerns me is that I've read various websites saying that each 47kg bottle should have about 656 kwh in, so for four bottles it's about 2627 kWh. When I look at my boiler it tells me it has used 50.3kwh hours over the last month, however I've got through 4 bottles!
I'm also concerned that the bottles I'm receiving aren't full. I know they have some space at the top naturally to allow for decompression, but from what I can tell they come about 3/4. See my black lines in the picture.
Should I be overly concerned? We've done some work to patch up and block potential areas of heat loss in the house, but I'm still worried there's is something wrong somewhere and It's going to leave us bankrupt!
