Another solar boiler from Atag
Atag has added a new model to its Q Solar boiler range. This latest model has a 3-coil integrated solar cylinder for solar, domestic hot water and central heating. The coils are of stainless steel and connected via 3-way valves and programmed to supply solar, blended and full gas heating as conditions dictate. Solar energy is collected using a glycol system. The main boiler has an inverted burner and water-cooled side walls and always operates in condensing mode. There are two models with outputs of 25 and 38 kW, and they can modulate down to 16% of full output.
