Choosing a water heater for your home can be a difficult process unless you have performed your research ahead of time. This is because there are many different types of water heaters to choose from, including natural gas, electric, and even solar. It’s also important to decide between buying a storage tank hot water heater and a tankless model. Each type of water heater offers many benefits, but each one also has some negative aspects, too.
A tankless hot water heater, also called an “on-demand” or “instantaneous” water heater, is different from storage tank models in one important way. Where a storage tank model will heat water and keep it hot whether it is being used or not, a tankless water heater only starts heating the water the moment a hot water tap is turned on. In a tankless water heater, the water is heated as it travels through a pipe and into the heating unit, creating a constant supply of hot water.
There are many benefits to installing a tankless water heater in a single-family home. Tankless heaters are ideal for small homes because they mount on a wall and take up a lot less room than a storage tank water heater. Tankless heaters are also energy efficient, since they only heat water when it is needed. You also will never run out of hot water, which may be important if you regularly use more than a storage tank water heater can provide. They also rarely develops leaks and can last longer than those with a storage tank, sometimes up to 20 years or more.
Along with the benefits, however, tankless water heaters also have a few disadvantages when used in single-family homes. Perhaps one of the biggest downsides of buying a tankless heater for a home is the cost. Depending on the model, they can cost as much as three times more than storage tank water heaters, and that is just for the unit itself. They also require professional installation due to the complexity of their system. This is especially true if you buy an electric one, which may require an electrical system upgrade to handle the extra power the unit will use.
Other important considerations when choosing a water heater is the amount of ventilation available to the area where the unit will be installed and the amount of peak water demand. Tankless water heaters require a certain amount of ventilation to function properly, without property maintenance they may shut down – usually when the water is running. You may not be pleased if your shower is interrupted due to ventilation problems. They are also limited in how much hot water they can produce at any one time. The more faucets or other appliances you are using at once, the lower the water pressure will be. For large rental homes with more than one bathroom with frequent use, a single tankless heater may not be able to keep up with demand.
Which type of water heater you choose for your home ultimately depends on your budget, the needs of your family, and whether the home is ready to support a tankless water heater system. Making decisions about major appliances can be difficult, but at Yukon-Air we are here to help.
