Tenth lunar month of central heating

by Unknown - 12:32 on 10 February 2015

Tenth Month (15/05/14-11/06/14

If you are a newcomer to this blog, it might be best to begin by reading earlier instalments of the blog, perhaps starting from "Why we installed a Smart".

Tenth lunar month of central heating
Total kg pellets used 311.5kg
Average daily kg (days in residence) 14.16kg
Metered kilowatt hours to central heating/hot water 706kwh
Gross kilowatt hour value of pellets 1495.2kwh
Space heating (calculated) 384.76kwh
Efficiency (based on measured input, metered output to central heating and calculated space heating) 73%
Cost of pellets £110.57
Potential RHI subsidy £176.27

During this month, we were away for six days, so the average consumption per day has been calculated for twenty two days for the lunar month. We had one sessions of heating, usually 16.30 to 22.30. Normally, we had the Smart set at a maximum output level of 3. During this month we did not normally use our wood stove We were happy with the Smart's performance throughout. Please note that the model which I used to calculate the space heating was developed for winter months, and thus the calculated efficiency rating for this month may be too low. However, with warmer weather some of the heating output is perhaps not strictly necessary, so it is not altogether misleading for a lower efficiency rating to be recorded.

Please read the notes on the fifth month which explain how space heating and efficiency are calculated
