Heat Load Calcs
A peak heat load calc is often the best starting point to designing any heating system. You want to be sure that when its very cold outside that the system can keep up. You also want to be sure that its just not plain oversized.
We may already have performed a peak heat load calcs for domestic customers who contact us so that when we put them in contact with one of our dealers much of the groundwork has already been done. We have put our system head to head with SAP calculations (which are onerous and time consuming) and we invariably get results that are so close as not to matter.
