The available heat for the boiler at 500°F and theoretical combustion equals 9, 150,000 BTU per hour. If 20 percent excess combustion air was used, the available heat at 500°F would be decreased to about 79 percent of the gross heating value for natural gas (calculated from Figure 4).

However, because new condensing boilers are 90%+ efficient and the price of gas is around 4p/kwh then we would – in your case – recommend upgrading your boiler and only use the panels to supplement the central
