For a fair few decades in the 20th century, the only option for residential water heating was to go with a tank water heater. In fact, that style of water heater was so ubiquitous that it’s probably the first thing you think of when you think about water heaters. That water heater type is still the most popular type in the country, but it’s no longer the only option when you look for a new water heater to install. The most common alternative to tank water heaters is to install a tankless model, which offers its own unique set of advantages.
Tank Water Heaters
A tank water heater, as the name suggests, makes use of a large storage tank to store and heat a set quantity of water. The storage capacity of these tanks vary pretty wildly, from less than ten gallons all the way up to over a hundred. Which storage tank you choose should be determined by the space you have available, how many plumbing appliances the system is expected to serve, and how many people are going to be placing demand on it at any given time. You don’t want to waste money and space on something too big, but you also don’t want to run out of hot water midway through a shower because someone else is running the dishwasher.
Tank water heaters are still common today because they offer convenience. The system is constantly operating, day and night in order to maintain the right temperature in the water supply. This means that it will be available at a moment’s notice, and will be able to cope with higher demand more easily. However, it also means that a lot of energy is being spent to heat water that isn’t used on an annual basis. As such, a tank water heater is not going to be as efficient as other water heater types.
Tankless Water Heaters
Tankless water heaters don’t use storage tanks, opting instead for heat exchangers similar to that of boilers. The system does not operate at all times, but remains dormant until there is an actual need for hot water. The water is heated as it passes through the heat exchanger on its way to its destination. When the demand for water subsides, the water heater turns itself off. This makes it much more
When the demand for water subsides, the water heater turns itself off. This makes it much more energy efficient than the tank variety, since it isn’t on 24/7. However, the tradeoff is that there is a slight delay between when you open the faucet and when you receive hot water. Tankless water heaters are also more easily overwhelmed than tank water heaters, since they don’t have a large supply to fall back on when demand increases. You should consult with a professional about which water heater type would fit your needs best.
