Replacing a water heater is nobody’s idea of a good time. It is a costly expense and there are tons of things you have to take into consideration when choosing the best water heater for your needs. It is easy to look towards the cheapest standard model, as this is an expensive thing to have to replace, but this is often a really bad idea in the long run.

Traditional water heaters are incredibly inefficient and they waste a ton of energy keeping a huge tank of water hot at all times, regardless of whether anyone needs it or not. This is why so many people have chosen to switch to the tankless water heater. With a tankless system, there are no tanks; water is heated near the point of exit when turn on the hot water tap; this means that water is heated only when you need it, saving you energy and reducing your total resource usage.

Things to consider when buying a tankless water heater

First and foremost, you will need to determine your budget parameters. Hot water heaters come in a wide range of shapes and sizes, with different features and levels of functionality, which is why they come in such a wide range of price points. By setting your budget ahead of time, you can easily eliminate options that are outside your price range and save a lot of research time.

Perhaps the most important consideration comes in determining what your actual hot water needs are so that you can get the system that best meets your needs and demands. This essentially requires that you make a list of the appliances in your home that require hot water and then finding out what the average flow rates for these appliances is. You can then add up all the different flow rates to give yourself a better estimate of what flow rate you require to meet your home’s needs.

You will also want to have a professional come out and take a look at your electrical (or gas) and plumbing systems to ensure that your home is set up to accommodate a tankless water heating system. It is also recommended that you have a professional install the system rather than trying to do it yourself. It can be complicated and even dangerous, so this is something that is best left to those with the tools and the knowhow.
