Ariston Boiler Reviews


Ariston Gas Boilers, Condensing Combi & microGENUS Comparison


The introduction of the Ariston boiler has meant these heating devices need not be confined in the basement or attic today.

Gone are the days when gas boilers were monstrosities that were hidden in obscure cupboards and dark corners of cellars that enable us to take hot showers and even heat up our homes. With 70 years of evolution Ariston gas boilers have come a long way.

What makes Ariston’s boilers unique is the fact that they are wall-hung. The designs are compact yet efficient and are 100 percent reliable. Each product passes through strict quality control that ensures maximum comfort to the end users.

Ariston Gas Boilers Vs. Condensing Ariston Boiler Comparison


There are three general types of boilers:

  1. Conventional Boilers are used if you have a gravity heating system. The water tank is probably situated in the attic or loft. Traditional boilers make use of a tank and a hot water cylinder where stored water is heated up before you use it.
  2. Condensing Boilers are very efficient but are pricier than a conventional gas boiler. An Ariston condensing boiler wastes very little heat because it extracts more heat from the steam produced by the water’s initial heating. This is possible because of an additional heat exchanger.
  3. Combination Boilers are often called combi boilers and Ariston combination boilers are best suited for small homes since the water is heated as it’s used, eliminating the need to store water.

Ariston boiler products present utmost comfort and are designed to be reliable and durable space savers. Ariston condensing combi boilers are eco- friendly as they are energy efficient since they use minimal fuel when operating.

The Ariston Euro Combi boiler is the perfect model for a home with a high demand for hot water. Unlike conventional models, it produces hot water instantly without the need to wait for the water tank to be refilled and reheated. This convenience can be especially felt in the morning when a household is getting ready to go to work or to school.
