Helsinge Central Heating Plant:

The Central Heating plant in the town Helsinge had the system installed in the autumn of 1997 as the first plant in Denmark. (This plant’s account year is = normal calendar year)

The total pipe loss before the system was install was calculated over a average of 3 years to a total of 10.486 MWh.

After the system was install the total pipe loss was calculated over a average of 4 years to a total of8.823 MWh.

The average savings pr./year was 1663MWh. = 10.486 MWh. - 8.823 MWh. at a prd. cost of 290DKR/Mwh.

When the production cost pr./MWh is 290 Dk.kr. then the savings was:
482.270 kr./pr.år = 1663 x 290 kr.

The total savings achieved over a 4 year period:

1.929.080 DKR. = 482.270 x 4

Approximate savings on the emission of CO² pollution.

Average savings on heat production
3078 MWh. = 40807 MWh - 37739 MWh.

According to data from the emissiontabel naturalgas has a emssion of CO² of 57 kg pr. GJ when it is converted to heat.

1 MWh. = 3.6 GJ.

Savings pr. Year on CO² pollution; 341.248 Kg. = (1663 x 3.6) x 57 Kg.
The total savings over the last 4 years; 1.364.992 Kg. = 341.248 Kg. x 4
