Tankless Gas Boilers. Why Pay More if There’s a Chance to Save?

Follow us


A traditional gas boiler heats water day and night within a storage tank. When we speak about tankless gas boilers, they heat water when you need it, instead of heating the liquid stored in a tank. Such systems are getting more and more popular, especially among people, who intend to cut down energy expenses by more than 25%. Why not heat water more efficiently if there is such a chance?

Why Do Specialists and Users Prefer Tankless Systems?

To begin with, tankless boilers last 5-10 years longer than tank ones. Besides, they take less space and are able to provide an unlimited amount of hot water. Would you like to find out more?

They say that tankless gas boilers are a worthwhile investment, because of three main factors:

  1. they save energy (up to 50% less)
  2. they save space
  3. they are environmentally friendly (less CO emissions)


These things make them a lot better than models with storage tanks.

As they require a lot less energy, they are cheaper to operate. Of course, the upfront costs are pretty high (unit itself + installation), but the payback arrives over a long term (after a couple of years), allowing to save 35% annually. Isn’t that beneficial?

Unit’s compactness is another reason worth speaking about. Such boilers can be quite easily mounted on any wall, placed inside a closet or tucked under the stairs, which makes them appropriate for a whole range of applications.

Today such tankless gas boilers find applications in floor heating systems, thus replacing traditional models. A tankless system can easily supply both the floor and the entire home with the hot water required. If you take a storage tank, there is always a possibility of sediments build up as well as bacteria growth, which is not the case with tankless boilers: they provide fresh and clean hot water all the time.

The list of additional benefits to take includes:

  • less risk of water damage
  • the boiler does not have any heat loss, unlike in case of a conventional water heater
  • life expectancy of tankless models in longer than that of  traditional hot water tanks (up to 20 years)
  • a gas-fired tankless boiler delivers higher flow rates, saving money in the long run
  • it provides 2-5 gallons of hot water per one minute

Purchasing a Tankless Boiler

While purchasing a tankless gas boiler, think of the amount of hot water your family needs. Ask yourself what the most amount of hot water you need at any given time is. Always consider the number of appliances that use hot water.

Of course, one of the main benefits is the fact such models can quite easily decrease the energy bills you get every month. This is great both for your family budget and the environment.

However, you should keep in mind that the true cost savings might be negligible, as too many things depend both on the size and type of the unit you are about to buy.

Think of the needs you have, the expenses you can allow and make your final choice. Giving preferences to tankless gas models you get the best!
