6 FAQs about [Household energy storage heat exchanger]

What are heat exchangers made of?

Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion. Stainless steel is also common in “compact” heat exchangers. Solar water heating systems use three types of heat exchangers:

What is a single wall heat exchanger?

A single-wall heat exchanger is a pipe or tube surrounded by a fluid. Either the fluid passing through the tubing or the fluid surrounding the tubing can be the heat-transfer fluid, while the other fluid is the potable water.

How does a heat exchanger protect a solar collector from freezing?

Heat-transfer fluids, such as propylene glycol antifreeze, protect the solar collector from freezing in cold weather. Liquid-to-liquid heat exchangers have either one or two barriers (single wall or double wall) between the heat-transfer fluid and the domestic water supply.

How does thermal energy storage work?

Thermal energy storage allows buildings to function like a huge battery by storing thermal energy in novel materials until it can be used later. One example is a heat pump. While electricity is needed initially to create and store the heat, the heat is used later without using additional electricity.

What is a double wall heat exchanger?

Double-wall heat exchangers have two walls between the two fluids. Two walls with drainage between the two and leak detection is required when the heat-transfer fluid is toxic, and are often used even with non-toxic heat transfer fluids such as propylene glycol (antifreeze).

How does a liquid-to-liquid heat exchanger work?

Liquid-to-liquid heat exchangers have either one or two barriers (single wall or double wall) between the heat-transfer fluid and the domestic water supply. A “double-wall” heat exchanger will drain any leak of heat transfer fluid from a gap before it could get into the potable water.
