Pros and Cons of Tankless Water Boilers


Your water boiler is a key part of your daily activities, since it provides hot water for various appliances in your home, such as your washing machine, shower, dishwasher, pool, and hot tub. Sometimes we don’t pay much attention to our water boilers because they don’t seem to cause any issues, or maybe you are already dealing with a leaky boiler and ever-increasing bills; whichever the case, you might want to review your options as far as getting a more efficient model that would save you money in the long run and could improve the supply of hot water to your home.

There is plenty of debate to whether tankless water boilers are in fact a better choice over conventional tank water boilers, which is why we have decided to round up the key pros and cons to be considered when assessing the possibility of going tankless. Compare and ponder on each element carefully and you can be the judge.



  • Good Price-Performance Ratio:


Just as in almost every product we seek to buy, we want to get great quality for a fair price. As far as tankless water boilers go, up-front prices will be considerably higher than those for conventional water boilers. Knowing this, tankless water boilers have been known to reduce energy costs up to 30 to 50 percent, which means you could be cutting your bills in half, and after some years, it could start to make up for the high up-front costs. Tankless water boilers mostly save energy because they save on standby heat, which means you won’t have 50 gallons of hot water waiting to be used as in conventional water boilers, but rather heats up water almost instantly only when you open a faucet.


  • Space Saving:


One of the main reasons tankless water boilers are widely used in European countries, for instance, is because of how little space they take up. There is no denying that that horrible, enormous metal tank sitting in your basement is not very pleasing to the eye and takes up almost half of a room. Tankless water boilers can be installed inside a closet or behind a door, which will give you more space in your home to use at your convenience.


  • Longer lifespan:


Conventional tank water boilers usually last 10 to 12 years, whereas tankless water boilers can last up to 20 years. This is something to consider if you are choosing a boiler for the family house you plan to live in for years to come. Five to ten more years of life mean five to ten more years of not having to replace your water boiler, which could be a good deal.



  • Higher installation and maintenance costs:


This is the factor that will probably dissuade most people from choosing tankless water boilers. Aside from the higher prices when buying tankless water boilers, their installation costs can add up to £2000, mostly because a larger diameter gas pipe might be needed to supply its increased consumption, as well as a special venting system which requires professional work. Even if operating costs should be lowered significantly, having this kind of money up-front might not be an option for some people.


  • Split output:


Another drawback to tankless water boilers is that they have a split output of water between the different fixtures in your home. This means that water will never run out if you are filling up a tub or taking a long shower, but your unit won’t be able to heat up any water if you decide to run your washing machine at the same time. This might not be an issue if you can organize your activities so that this overlapping will not happen, but sometimes this can be difficult if there are many people living in the same space.


  • Increased electricity consumption


Gas powered tankless water boilers are the kind most widely used, however, there are also electric models that are usually cheaper to install. Nevertheless, electric models are not as effective as gas-powered models in heating up water, which will result in high energy consumption and excessive bills, especially since electricity costs are very steep in some areas.

So, there you have it, everything you need to consider when comparing and choosing your new water boiler. You may believe tankless may or may not be the right way to go for you, whichever the case, it is essential that you understand your needs and how this option adapts to them or not. There is no simple or right answer for your water boiler doubts; you must simply analyse what is best for your space and not just be swayed by what advertisements say. Take some time to review your options and you will be on the right track towards deciding.
