How water heaters work

Your home relies on a working water heater for, well, lots of things. Clean laundry. Hot showers. Great-looking dishes. Your water heater does a lot. But, how exactly does it heat up all that water? In this blog post, we’ll review the details about how water heaters work.

Plumbers & Plumbing Repair Lake Havasu CityHow do water heaters work?

A water heater tank is fed cold water by a dip tube at the bottom. As the water enters the tank, it’s heated at the bottom—this is where the heating element is. As the water heats up to a temperature of between 120-140 degrees, it begins to rise over the colder water just now entering the tank.

Eventually, the tank is filled with water, and the heat-out pipe at the top of the tank allows water to escape. Since the hot water is at the top, it’s always the heated water exiting the tank and into your home.

By using physics (the nature of heated water to rise over cold water), your water heater is able to quickly take cold water, heat it, and send it to your faucets, shower heads, and washing machine.

What is an anode rod?

Over time, the constant mix of water and metal leads to corrosion. Left unchecked, this corrosion would immediately attack the inside of the tank, quickly destroying it and causing a whole host of problems for your home, including—probably—a tank burst.

Fortunately, your water heater has a way of protecting itself. Water heaters contain a sacrificial anode rod. This rod is designed to attract corrosive elements in the water, taking the damage instead of the tank.

Anode rods only last so long, though. Generally, replacing an anode rod in the middle of your system’s life is a good idea. If you’d like Air Control to replace your water heater’s anode rod, contact us.

What are tankless water heaters?

Also known as “demand-type” water heaters, tankless water heaters heat your home’s water without the use of the tank setup described above.

Typically wall-mounted, tankless water heaters run cold water from your home’s tap through it, using heating elements to rapidly heat the water to temperature before sending it out into your home.

Unlike standard water heaters, which have a limit on how much hot water they can provide your home at once, tankless water heaters can supply your home with a virtually unlimited amount of hot water. These systems are perfect for large families with multiple people showering in the morning or at night.

How AC systems work

Almost everyone in Lake Havasu City has an air conditioner. But, how exactly do air conditioners keep your home cool, even on the hottest days of summer? It’s not magic: it’s science, and in this blog, we’ll break down how AC systems work and keep your home cool.

How do air conditioners work?

Every air conditioner has four main components: a compressor, an evaporator, a condenser, and expansion controls. These four parts work in sequence to cool your home.

Your air conditioner uses refrigerants (read more about the R-22 phaseout) and some basic physics to operate. In the evaporator, that refrigerant is run through coils, with fans blowing your home’s air over them.

The refrigerant absorbs the heat of the air, going from a liquid to a hot vapor inside the coils. It then runs to the compressor, which “compresses” it under greater pressure, increasing the heat.

Finally, this gas enters the condenser, located outside your home. The heat from the gas is released into the outdoor air. As the gas cools, it state changes back into a liquid. The expansion controls regulate the movement and flow of this restored refrigerant back into the evaporator, starting the process over again.

Why do air conditioners dehumidify?

All air conditioners also remove humidity from the air as they cool it. When that evaporator coil absorbs heat, it also removes moisture from the air. Warm air is much better at holding moisture than cold air (which is partially why summers are more humid than winters).

Luckily, this is considered by many homeowners to be a feature, not a glitch. Humid air feels hotter on the skin, so an air conditioner simultaneously cooling and drying air is making you more comfortable in two different ways.

What makes refrigerant special?

R-22 and the newer R-410A are hydrochlorofluorocarbons. Basically, this subset of chemicals are able to very easily “phase transition” between being a liquid or a gas. This makes them incredibly useful for the purposes of air conditioning.

R-410A is becoming widely accepted as the industry standard in air conditioning refrigerant because it does not contribute to ozone layer depletion like R-22 does.
