Hello friends
I have used the Direct evap coolers with baseboard gas boiler template to evaluate a building whose cooling system is a simple electric water cooler and heating is simple gas radiators. But the domestic hot water does not have a separate fuel tank. That is, a dual-function gas water heater without a tank that supplies both the heating system and domestic hot water, so I have to use the HB SHW System. According to the image, I chose this workflow. But I feel that the gas consumption is counted twice and it is not logical. Can anyone suggest me a way?
