Many wood or pellet fires, ranges or burner systems can have wetbacks fitted to them. A wetback can work as a valuable supplement to your hot water system.
Keep in mind
Adding a wetback means you get less of the fire's heat going into the room. Most existing fires have adequate capacity to do both, but keep it in mind when sizing a new wood or pellet fire.
Not all fires and hot water systems are suitable for wetbacks. Check with your fire manufacturer and your plumber to see if a wetback will work for you.
- There is a limit to how far away a water cylinder can be from the wetback before it ceases to work. Likewise the pipes must be run as directly as possible and include a slope so that the water can naturally circulate through the heat exchanger.
- Many councils have clean air requirements in place for urban areas. Check what fires and wetbacks you can install with your local city, district or regional council.
