How do I take care of my water heater?
Water heaters require care for them to have a long lifespan. We advocate following the manufacturer’s instructions to ensure that you get the maximum benefit from the product. The first step is to purchase the appropriate product size for your home and water needs. You should also follow the brand instructions during installation. If you are not an expert in installing water heaters, it would be best if you used the services of a professional to ensure you do everything right. You should also perform a test run immediately after installation and ensure everything is working appropriately.
Flushing the water heater once a year is crucial in keeping the system operating optimally. Over time, mineral buildup can cause clogging and corrode the system’s interior, thus causing reduced efficiency. When flushing, you need to turn off the power source and detach the valves. Then follow the manufacturer’s instructions to run water through the system for a while.
You can also use the services of a professional plumber to inspect and do the necessary repairs to keep the unit serving you for longer. When you service your heaters annually, you enjoy fewer breakdowns and less costly repairs. In the long run, this saves you a considerable amount of money.
What to consider when purchasing a tankless water heater
No matter how fancy or pocket-friendly a water heater seems, you should not purchase it blindly. You need to counter-check the requirements and see whether it fits your needs. The first thing you need to know is the kind of power supply the heater requires. Most heaters use either natural gas, propane, or electricity. Ensure that you have the needed energy source before bringing home the heater. When it comes to electric power, check the heater’s power supply requirements to confirm whether your home can comfortably supply that amount. If the heater requires a higher voltage than is available, it might not produce sufficient heating for all your household needs. However, a higher voltage in your home might damage the heater significantly.
Another item to consider is your household needs. You need to call a plumber to help determine the fixture’s flow rate and whether it corresponds with what the heater can comfortably supply. Having a higher flow rate will prevent you from getting enough hot water, and you might not be able to use more than one fixture simultaneously. This is a significant inconvenience, especially for large households.
Apart from the flow rate, you should also consider how many people may require to use hot water at the same time. If you have a higher demand for hot water, you need to find a large heater. Buying a small one to save on cost will strain the unit and cause a short lifespan. However, buying something bigger than what you need will only make the unit inefficient, and it will operate below its capacity.
Before you purchase a water heater, ensure that you have qualified personnel to perform installations and general maintenance. You shouldn’t buy a product that will cause you sleepless nights due to a lack of professional services. If you are not sure whether the technicians near you can do sufficient work, go to the manufacturer’s website and look for the pros they have near you. You can also ask the seller for this piece of information.
Finally, you need to check the physical size of the heater and look for an appropriate location before bringing it to the house. Go through the manufacturer’s website, and confirm the accurate dimensions of the unit and the conditions necessary for storage. After that, look for the best place, and prepare the area. You should also clear the site of any clutter and create some extra room for ventilation. Whether you want to mount it on the wall or place it on the ground, ensure it is away from your children’s reach.
What tankless water heater size suits my home?
Before you purchase your tankless heater, you need to know if it’s the best fit for your home. All brands make different sizes of heaters to ensure they serve various needs. Despite the physical size and price, you should ensure that you understand its capacity before buying. We advise getting professional assistance from a trained expert who can help you calculate your household requirements and if your desired heater can function optimally.
For example, if you have a rental apartment, you need a tankless heater with a high capacity that can supply adequate water to multiple users at a time. This is because you might find several residents needing hot water or taking a shower at the same time. Therefore, your preferred heater should be one that can guarantee enough heated water for as long as the fixtures keep running. Getting a small heater will cause inconveniences since it will produce water at a lower temperature than you would like.
On the other hand, if you need a heater for a small household, you should not go for one that has excessively high capacity. The bigger heater will cost you more money, and you will underutilize its function. In the long run, you will pay higher energy bills due to its consumption while only using a small portion of its capacity.
Therefore, you need to consult the manufacturer or an expert plumber and let them help you decide on the best fit for your needs. You will enjoy adequate heating, reduced energy bills, and a long-lasting heater. You also avoid frequent heater repairs due to overuse or inefficiency. It is essential to research different brands and read reviews about their products to get firsthand information on what to expect from their heaters.
Having various choices ensures that you make the best decision and avoid investing in the wrong heater. Once you know the right size, you can compare the physical size, affordability, appearance, and warranty offered by the manufacturer.
