Should the return line be hotter than the supply line on my outdoor wood furnace?
The system should probably be designed for no more than I would say 40°F between the supply and return at the OWB. If you are getting MORE than this it indicates either insufficient flow, or you are removing too many BTU from the flow that exists.
How does a wood boiler heat water?
The furnace works by burning wood to heat water. The heated water is circulated through insulated underground pipes called insulated pex pipe to the buildings being heated. From there it connects to your forced air, in-floor radiant, or indoor boiler heating system and sends the heat around your home.
How does a hardy heater work?
The “Hardy” provides hot water for your bath, shower, kitchen, and laundry from hot water stored in the domestic water heater. As this water passes through the heat exchanger it is heated and then enters the cold water input on your hot water heater.
Which heat exchanger is most efficient?
Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities.
How big of a heat exchanger do I need?
Many customers ask, “how do you know what size plate exchanger to install in your domestic hot water tank?” A simple rule of thumb is 2 to 3 people in one house will determine a 10 plate. A 10 plate heat exchange is enough for 2 and 3 people.
