Budgeting: gas central heating and hot water

Anthony_C

Just checked my old records and found my Nov 2015 to Nov 2016 meter monthly readings for anyone looking for budgeting guideline
Gas boiler was 40 years old balanced flue
Hot water cylinder
Approximate monthly kWh: -
Nov 15: 1,122 kWh
Dec 15: 1,021 kWh
Jan 16: 2,300 kWh
Feb 16: 2,457 kWh
Mar 16: 2,244 kWh
Apr 16: 897 kWh
May 16: 561 kWh
June 16: 606 kWh
July 16: 561 kWh
Aug 16: 561 kWh
Sep 16: 561 kWh
Oct 16: 1,166 kWh
Total 2015-16:14,058 kWh
Total 2016-17: 15,486 kWh

July, August and September look a bit suspicious at exactly 561kwh - were these estimates?

I appreciate your reply, but your making it more difficult than it needs to be, I'm not doing this as a contest. I'm doing this to help those asking for our help.

The figures are from monthly meter readings, but NOT exact month ie March 3 to April 6, so extrapolated the readings. Just to give an idea of a month kWh. The year total is accurate.

Perhaps you can share your own monthly meter readings?

How are you proposing your figures are going to help people?

Even if someone had exactly the same boiler as you their own usage will be very different depending on:

- How many rooms they have
- how many people they have living there
- how long the heating is on and temperature
- how big the raditors are and what they are set at
- how well insulated the house is

Plus lots of other factors.

You could have either myweekly or monthly readings going back over eight years but they wouldn't really be much use to anyone else as we are all electric and have a heatpump.

What is more useful is my energy profile over the year as I suspect that it's pretty similar to most others and gives a much better picture of how much extra is used in the winter compared with the summer.

The following is my monthly average over eight years and allows me to pretty well predict how much energy I'll use in any given month.

My average annual consumption is 7200kwh, so just multiply your annual consumption by the percentage (so Jan = 7200x16% = 1152kwh) to get an estimate

Jan = 16%
Feb = 14%
Mar = 12%
Apr = 7%
May = 4%
Jun = 4%
Juy = 4%
Aug = 4%
Sept = 4%
Oct = 6%
Nov = 11%
Dec = 14%

Obviously if the month is significantly colder or warmer than average then it'll either cost a bit more or a bit less but overall it's quite consistent.

I have posted my home type, stat settings etc
, heating & hot water type, energy use, all on another detailed thread, as an example.

If anyone queries I will gladly post the details again and try and explain how it may relate to them

I have stated that energy use differs each year 14,000 kWh, 15,500kWh another and the past year 16,000 kWh
