Most homes need a working water heater.
Without it, you’ll constantly be taking icy cold morning showers and running behind on chores that involve hot water.
If it’s a repairable problem, you can fix it, but sometimes, you simply need to buy a new water heater.
Before heading out on your hunt, you need to inspect a few things. Let this be your guide.
Water Heater Type
There are various types of residential water heaters, each with pros and cons.
- Storage Tank Water Heater: The most common and most reliable type. It stores a set amount of hot water, but uses more energy to keep water heated all day.
- Tankless Water Heater: Heats water only when needed. It saves energy but costs more to install.
- Hybrid Water Heater: Combines tank storage with heat pump technology. They’re ideal for bigger homes.
- Solar Water Heater: Runs on energy from the sun, making it eco-friendly.
When choosing a unit, compare it to your home’s usage pattern and available space.
For example, a person looking for a hot water system Brisbane homeowners typically use may look for a model that fits the area’s weather and meets local regulations.
Size, Capacity, and Space Needs
Size matters when you buy a new water heater.
One that’s too small for your home needs will run out of water quickly. Meanwhile, one that’s too big will waste energy.
Another factor to consider is storage tank capacity, which is measured in gallons.
For tankless water heaters, it’s the flow rate, or how many gallons per minute they can heat.
A small house could use a 30–40-gallon tank, but a larger house with five people could need 50 gallons or more.
A tankless with a five- to seven-gallons-per-minute rating generally accommodates showers and appliances at the same time.
Mind the space in your boiler room, too.
A tank unit needs enough room for the cylinder and maintenance clearance.
Tankless models conserve space but may involve mounting on walls and altering plumbing leaks.
Energy Efficiency
As energy costs are increasing, energy-saving practices are becoming increasingly common in homes.
An energy-efficient water heater minimizes monthly expenses and has a lower environmental footprint.
If you’re unsure how energy efficient your water heater is, check the Energy Factor (EF) or Uniform Energy Factor (UEF) ratings.
Higher numbers indicate better efficiency. Consider a heater with Energy Star certification, at least.
Energy-efficient models may be pricier initially but frequently recoup their costs in reduced energy consumption.
Some jurisdictions can provide rebates or incentives for using environmental-friendly systems, particularly solar collectors and hybrid systems.
Fuel Source
Before you buy a new water heater, check your fuel source. Sources often narrow down the options. Common choices include:
- Electric: This fuel is simple to install and easy to find, but can be more costly to use in high electricity rate areas.
- Natural Gas: This fuel warms the water rapidly and tends to be cheaper to use, but must be well-ventilated.
- Propane: This type of heater is acceptable where there are no natural gas pipes, but it’s more expensive.
- Solar: This fuel has a low operating cost after installation, but it depends on the weather and location.
You need to take utility costs, local availability, and ease of water heating system maintenance into account. If you have a municipal grid serving your area, electricity prices and service reliability can affect which type of water heater will perform best.
Installation Requirements
You may have some water heater models already on your list.
But check the installation requirements before you make the final decision.
Your new tank may not fit into the existing space.
For example, if you want a tankless system, you may need upgraded gas lines, venting, or electrical panels.
Even a replacement tank may need modifications if building codes in your area have been updated.
It’s possible to install new tank water heaters yourself, but only when you have the proper tools and know-how.
However, consider hiring qualified home services when dealing with gas lines or high-voltage electrical components.
The professionals will install your water heater properly and provide hot water as needed.
Maintenance Needs
Always remember to include your water heater in regular home maintenance tasks. Keeping it in excellent condition allows it to produce hot water whenever needed.
Maintenance depends on the type of water heater you plan to buy.
Tank water heaters need regular flushing to remove sediment buildup and anode rod replacement to prevent rust.
On the other hand, tankless systems require periodic descaling, especially in areas with hard water.
Some models are designed for easier upkeep, with accessible panels and user-friendly components.
Choosing one with simple maintenance steps can lead to time and cost savings.
Warranty and Brand Reliability
Despite maintenance, water heaters do occasionally malfunction.
That’s why you’ll want a warranty. Economy versions might have a three- to six-year warranty, but high-end versions can be 10–12 years or longer.
A longer warranty usually means higher-quality materials and construction.
For other homeowners, a name brand isn’t necessary.
Some water heater brands are, however, preferred over others because of their outstanding reputation.
Check if your desired brand has rave customer reviews, serviceability, and availability of water heater parts.
A lesser-known brand with no local service center could add stress to your life.
Budget and Total Cost of Ownership
The cost of one unit doesn’t reveal all that you pay for. Installation, maintenance, use of energy, and water heater repair are usually included in the cost of ownership.
A less expensive electric model may appear to be a bargain but end up costing more in electricity bills, for instance.
On the other hand, a gas or hybrid high-efficiency model may cost more at first but may end up saving you thousands during its lifetime.
Safety Features
Modern water heaters often include built-in safety measures. Common ones include:
- Temperature and Pressure Relief Valves: Vent excess pressure to avoid tank explosions.
- Automatic Shut-Off: Shuts off power or gas supply during emergencies.
- Anti-Scald Technology: Maintains hot water temperatures within safe levels, particularly valuable in households with children or elderly members.
Confirming these features prior to purchase ensures your property and the individuals at home are safeguarded.
Wrapping Up
It can be fun to buy a new water heater, but first, you should check certain aspects.
There are a number of factors that may affect comfort, operating costs, as well as safety.
Compare, inspect specs, and look at long-term expenses.
A properly selected water heater, based on natural gas, electricity, or the sun, will work quietly and efficiently, fulfilling your hot water needs.
