What to Look Out for When Buying a Water Heater

| Tuesday December 20, 2022

Nothing beats a warm shower to wash off the tiredness of your body after a stressful day at work. There are tremendous benefits to taking hot showers. These include lowering blood pressure, relieving muscle tension, and moisturizing the skin. This is why investing in the best shower heater in the Philippines can be a game changer for many households nowadays.  

bathroom water heater is essential if you want an exhilarating shower and better sleep. Many people would only look for the shower heater price when buying a water heater for their shower. However, there are several other factors to consider when choosing a water heater for your bathroom. 

If you need to know which water heater you should add to your shower, here are some things you need to consider when shopping for a new water heater. 


Type of Water Heater 

There are multiple types of water heaters available in the market, including tankless (instant water heaters), traditional tank-style (storage water heaters), solar, and heat pump water heaters. Knowing which water heater type you prefer is vital to help you make an informed decision when buying a new water heating unit.  

Tankless water heaters, also known as on-demand or instant water heaters, heat water as it passes through the unit rather than heating and storing it in a tank. This provides consumers with an unlimited supply of warm water, allowing them to enjoy warm showers at any time of the day. This water heating unit also only works when turned on, which means it is more economical than traditional heaters. 

On the other hand, traditional tank-style water heaters store hot water in a tank, allowing it to be quickly and readily available when needed. A standard storage water heater can hold up to 80 gallons of water. This type of water heater can provide a decent warm water supply to multiple water points, even during blackouts due to natural disasters.

Meanwhile, solar water heaters use the sun’s energy to heat water, making them a more environmentally friendly option. Heat pump water heaters use electricity to move heat from the air or ground into the water, making them more energy-efficient than traditional electric water heaters. 


Water Heater Size and Capacity

Another factor you should consider when choosing a water heater is the size and capacity of the water heater. Your water heater should be just the right size for your shower, not too big or too small. For instance, tankless water heaters are great for small spaces, while traditional water heaters are best suited for bigger houses. 

The size of a water heater is also essential when choosing one because it determines the amount of hot water it can produce. A larger storage water heater is suitable for households with a high demand for hot water. On the other hand, a smaller water heater will suffice for families with low demand for hot water. 

For most tankless water heaters, the build of the water heating appliance is generally more compact and smaller than tank water heaters because they do not have a storage tank. Thus, there is no need to worry about the capacity of water a tankless water heater can hold.


The Type and Cost of Fuel 

Most water heaters run on fuel, and you should know the suitable fuel type that works perfectly for your bathroom. The types of power for water heaters include electricity, fuel oil, propane, solar, and geothermal energy. Among these, electricity and natural gas are among the most common. The available fuel source in your area narrows down your choices in what type of water heater you should use. 

Before shopping for water heaters, you should know which sources are abundant in your area. Of course, the cost of fuel should also matter. The type of fuel you use for your water heater determines its energy costs. The best water heater for your household is the most cost-effective type of water heating appliance that can use the fuel source available in your location. 


Storage Capacity 

When it comes to storage capacity, you don’t only want to measure the amount of water that a heater can hold. Consider how fast a water heater warms the water. When looking for a water heater, you should check how many gallons it can hold per minute and its first-hour rating. The first-hour rating (FHR) refers to the total number of gallons the heating unit can supply in an hour. 

You should consider your home’s size, the number of occupants, and your water usage, including the number of bathrooms, the number of hot water-using appliances, and the frequency with which they are all utilized at once when determining the water heater’s storage capacity. For instance, you will want a water heater of 30-40 gallons if you only have one shower. The more bathrooms you have, the bigger capacity you will need. 


Energy Efficiency 


Some water heaters are better than others at conserving energy, so it’s essential to research and choose the best option for your home. Water heaters save a lot of power, but other types do it better. The Energy Star® symbol is one of the best things to look for when searching for water heaters in terms of energy efficiency. 


A water heater with this symbol means that the brand is known for having high-quality and reliable performance while saving energy and using less greenhouse gas. Moreover, consider the energy efficiency (EF) rating when buying a gas- or oil-fired water heater. This is a sign of the water heater’s efficiency, which applies to tank and tankless types. A higher EF indicates greater efficiency in using energy.



The best water heater for your home is the one that caters to your home needs the most. The size of the heater, fuel type, storage capacity, and energy efficiency should matter first when choosing. Once you assess your needs, you will already know the kind of heater you would install in your shower.
