Every house requires a reliable and steady supply of warm water for different household tasks. The hot water demand is primarily determined by the size of the family, the number of tasks that require warm water, and weather conditions. So how do you buy a suitable water heating system?

Currently, the market offers different forms of water heaters, and picking the right unit for your home might not be easy if you don't know much about them. Here are fundamental factors you should consider as you shop for a water heater.

Determine the Preferred Source of Energy

One crucial aspect you must familiarize yourself with before buying a heater is the energy source you'll use. The fuel you pick will determine the unit's efficiency, operational costs, and size. So, know the possible options and compare them to make smart choices. Some popular fuel options you can consider today, depending on their availability in your locality, include electricity, natural gas, geothermal energy, fuel oil, solar energy, and propane. Each fuel source's benefits vary, so ensure you know all the pros and cons before choosing. You can also consult your HVAC contractor when in doubt.  

Determine if the Heater Should Have a Tank or Be Tankless

This is another feature that confuses many, and there isn't a definite answer for everyone. A tank water heater is common because people who built homes in the last several decades primarily installed this kind of heater. They are preferred because they keep the heated water in the tank, so users get it instantly when the need arises. So, you'll use the source of fuel throughout to maintain the warmth. Note that the hot water gets depleted when you run the system for long, so you'll have to wait for the unit to preheat water before using it again.

Tankless heaters are a more updated version that lacks a reservoir. They are considered more efficient as the water is heated on demand once the taps or shower knobs are turned on. This version of water heaters is easy to maintain, but you have to consider its capacity carefully because this will determine if your needs will be met or not. Also, you'll have to wait for some time for the hot water once the taps are open.

While there are other factors you need to consider when buying a heater, you shouldn't forget these two as they are significant. Remember to keep your budget in mind and talk to an HVAC contractor when you need expert help.
