Condensing Boilers: How Much They Cost and How to Choose Them

What

The condensing boiler, a typical product from Don't Waste catalogueIt's simply a hot water boiler in which the water vapor from the exhaust gases condenses. This recovers the latent heat of condensation, resulting in higher energy efficiency than a conventional boiler. Condensing boilers can be either floor-standing or wall-mounted.

Types of condensing boilers

Condensing boilers come in two types: wall-mounted or floor-standing. Wall-mounted boilers are the most commonly used and can be installed indoors or outdoors. In this case, a metal casing will be required to protect the boiler from wind, rain, and snow. Floor-standing boilers are more suitable for larger spaces; they are floor-standing and can produce much more hot water than wall-mounted boilers.

The savings

If you're looking for a viable alternative to gas boilers, combining energy savings and reduced emissions, and therefore pollution, in the same solution, consider a condensing boiler.

How it works

These are very simple systems, increasingly technologically updated and highly energy efficient. which allow the heat from the exhaust gases to be recovered and put back into circulation.

The advantages

The advantages of the condensing boiler, whose average duration is around twenty years, are evident. While with a traditional boiler, the heat lost through the flue gases is 10 percent, with a condensing boiler it doesn't exceed 1 percent. And the system's efficiency increases by approximately 30 points. In addition to reducing pollution and harmful emissions, the condensing boiler leads to an average saving on the domestic energy bill of 30 percent.

Costs

Now let's look at costs. For a family living in a 100-square-meter home in a warm area and spending €1.500 on gas (for heating and hot water), the investment is approximately €2.500, all-in. Condensing boilers, including system costs, pay for themselves within three to four years from the date of purchase. But then you have to factor in the benefit of the ecobonus, with a discount on the invoice of between 50 and 65 percent. And keep in mind that, for condominium purchases, the ecobonus increases to 110 percent.

How to choose a condensing boiler

Condensing boilers can be wall-mounted, outdoor, or built-in. For a complete overview of costs, visit the Convienesempre website, which sells appliances and heating and cooling systems for homes and offices. Their selection includes top brands such as Vaillant, Beretta, Immergas, and many others.
