What is a sidearm water heater?
Sidearm water heaters were developed decades ago so that boilers could provide both space heating and domestic hot water. Generically, they are water-to-water heat exchangers that transfer heat from the boiler water to domestic water whenever the latter is flowing through.
How does a sidearm heat exchanger work?
Thermosiphon is a method of heat exchange through convection. By using convection, water from your hot water heater can be drawn up through your heat exchanger without the use of mechanical pumps. The larger outer tube is plumbed into the water flow loop coming from your outdoor wood furnace.
What is a heat exchanger in a tankless water heater?
In order to get you that piping-hot shower when you want it, a tankless water heater uses a powerful heat exchanger to raise the temperature. A heat exchanger is a device that transfers heat from one source to another. This exchanger is activated by the incoming flow of water.
What is a heat pump hot water?
Heat-pump hot water systems use a refrigeration cycle to extract heat from the surrounding air. They then use a heat exchanger to heat water in an insulated storage cylinder. A heat-pump hot water system can be thought of as a type of solar water heater because the heat in the air ultimately comes from the sun.
What is a hot water heat exchanger?
This arrangement is what we mean by a heat exchanger: the gas jets cool down and the water heats up. A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) without the two fluids having to mix together or come into direct contact.
How do you size a plate heat exchanger in floor heat?
What Size Should the Plate Exchanger Have? 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.
How does a sidearm heat exchanger work in a hot water heater?
To function, the heat exchanger is mounted to the side of your hot water heater. A process called thermosiphon creates heat exchange through convection, heating the water inside your tank. The thermosiphon process draws cold water from your hot water heater through the heat exchanger without the use of any mechanical devices. Sounds great right?
How does a chilled water coil work in an air handler?
The air to be cooled moves through the fins, and either water or an ethylene or propylene glycol solution move through the tubes. This is a type of heat exchanger mostly used in commercial and industrial air handler units. A simple form of water coils have been around for centuries.
How tall should a sidearm heat exchanger be?
Plumbing into the relief valve would cause an arch in the plumbing, creating a heat trap and possibly interfering with the thermosiphon. If you plumb into the hot water inlet DO NOT extend the heat exchanger any higher than 3-4 inches above the hot water heater. Try to stay as level as possible to the top of the tank.
Which is the best size chilled water coil?
3/8, 1/2, and 5/8 are available. Although 5/8 inch tube diameter is the most common selection for chilled water coil because it offers many wall thickness options which can increase the lifespan before tube erosion becomes a problem Free shipping on all chilled water coils!

How do you replace a coil on a hot water heater?
Hook up the electrical leads and replace the panel over the lower heating element. Now turn the water back on so it can fill the water heater by turning the shut off valve clockwise. Once this is done go to the breaker box and turn back on the breaker that powers the hot water heater. Wait for about 30 minutes.

Where is the anti syphon valve on a sidearm heat exchanger?
Newer hot water heaters have an anti-syphon valve installed in the top of the hot water exit. It is a blue plastic valve that needs to be ripped out using a pair of needle nose pliers. If you do not remove the anti syphon valve the thermosiphon process will not work.
