Running Costs:
- 9000BTU = R0.45/hour
- 12000BTU = R0.54/hour
- 18000BTU = R0.87/hour
- 24000BTU = R1.24/hour
- 30000BTU = R1.58/hour
BTU Required
The rule of thumb is that you take the total square meters that you require to be heated or cooled and multiply this by 600, this will give the total BTU's required.
Back to back means up to 1 meter pipe run. If more then 1 meter we will add R150 per meter for extra pipe. Truncking will be an extra R150 for 3 meters.
