Heating Things Up: Tanks And Anodes

A large number of homeowners choose to install new home appliances (or to upgrade the existing appliances) when renovating the house. Here are a few essential tips that a homeowner should have in mind when shopping for a new residential water heating system.

Tankless Vs Conventional Style Water Heaters

The thought of having a tankless water heater often sounds exciting for a large number of homeowners. This excitement is not without good reason. An investment in a tankless residential water heating system can easily translate to huge energy savings because the operation of tankless heaters relies on natural gas as opposed to electricity.

Also, tankless water heaters are designed to heat water (use energy) only when their faucets are turned on. In comparison, conventional-style water heating systems will use energy continuously so as to keep the water in the storage tank hot even when the water is not being used.

However, the potential energy savings associated with the use of tankless water heaters come with strings attached. Tankless heaters deliver hot water to one faucet at a time. Thus, at least one person will be forced to make do with a cold shower when two or more showers run simultaneously.

Also, tankless units often come with a heavier price tag.

Magnesium Vs Aluminium Anodes

Homeowners undertaking renovation-related activities on a tight budget often choose to stick to the conventional-style water heating systems. The choice between magnesium and aluminium anodes is an important one for such homeowners.

One advantage associated with the use of magnesium anode rods in residential water heating systems is that these anodes are often better at preventing the corrosion of water heater storage tanks. Because magnesium is more chemically reactive than aluminium, the magnesium rods will produce a stronger current in the storage tank than that which would have been produced by their aluminium counterparts.

Aluminium rods are preferred for the fact that they're often more durable than magnesium rods. This is because aluminium rods have greater resistance to the potentially damaging effects of metal corrosion. Thus, aluminium rods will have a slower rate of wear and tear and the need for their replacement will be less frequent.

Lastly, aluminium anode rods are often coated with zinc metal so as to alter the chemical characteristics of water stored in the tank. This alteration helps to suppress the production of foul odour from the residential water heater.
