How much does it cost to install a condensing boiler?

Having a boiler in our house thinks a huge tool item. In addition to providing us with hot water for any occasion, it also offers us an incredible heating system. Among the different configurations of boilers accessible on the market, having one gas condensing boiler is, without a doubt, the preferable selection, since they are the most modern and the most effective, admitting to save up to 30% of the fuel, since they reuse the energy of the water vapor that is produced.

However, the acquisition and installation of this set is not a simple price, on the contrary, you need to take many euros out of your pocket. But its effectiveness and virtues make the price worth it. If you need to change your old and worn boiler for an exclusive one of this class, here we will explain all the details of this installation and how much a condensing boiler costs.

How much do gas boilers cost?

Beyond that our purpose is to provide the approximate cost of installing a condensing boiler added to the value of the whole, it is favorable to understand the different costs of these boilers on the market.

The cost of these devices varies depending on the brand and, of course, on their capacity. Currently, a condensing boiler usually has a price between 900 and 2000 euros. However, the cost of some equipment can exceed 12,000 euros.

All in all, the value of this class of boilers is not that high if we compare it to the value of an electric boiler.

What boiler capacity do I need for my home?

This aspect is considerable at the time of quoting the price of a condensing boiler and therefore the final value with aggregate assembly. A professional in this field can make the calculation of the capacity you need without any problems, but it is not different to understand how to know this value so that you can orient yourself in a better way.

To understand what capacity the boiler you need for your home should have, you have to do a simple mathematical operation, in relation to your requirements. In this way, we have the following calculations:

• For heating only: To get an approximate result of the capacity you need in this situation you just have to know the m2 of your home and carry out the following operation: m2 x 100 W.
• For ACS boilers (Heating and hot water boilers): In this situation you must take into account the maximum number of people who can live in the house. If the house can accommodate up to 14 people and taking into account that each subject may require up to 30 liters of DHW water, around 420 liters of water must be heated. From this calculation and taking into consideration a time of 30 minutes with a thermal jump of 50º, you must make the following calculation:

m * Cp (∆T)= P

m: represents the mass flow rate of the water to be heated (kg/h) with a water consistency of 1 l/kg

Cp: ​​it is the heat of the water. (1 kcal/kg·ºC)

∆T: is the thermal jump of the fluid (ºC)

P: is equivalent to the elementary capacity of the boiler (kcal/h).

Factors that influence the installation value of a gas boiler

There are three noteworthy points that are decisive when quoting the value for the installation of a condensing boiler, which are described below:

1. The geographical location of the home where assembly of the set will take place: If the sapling prepared for this installation has to travel a huge distance to reach the home, the value will be greater.
2. The use that will be provided to you in the boiler: can be used as a heating system, hot water supplier or in bathroom services.
3. The dimensions of the house or the space to which the boiler will supply.

It is considerable to consider that this installation development needs the services of an expert staff in the subject. Otherwise, you run the risk of ending up with an incorrect installation that can cause:

• Negligible expenses in the long run.
• Bad exercise of the new boiler.
• Leakage security issues.

Then, What is the cost of having a gas boiler?

As you already know, the final value of this procedure will vary according to the factors mentioned above and, of course, the brand and capacity of the condensing boiler that we choose to purchase. Beyond that, we will try to provide you with an approximate value of this system for your guidance.

The price of installation of gas boilers, i.e. labor alone, can cost you between €250 and €770. However, the average value is €510.

In addition, we also put at your disposal the following installation costs together with the different costs of boilers according to power:

25 kW boiler: €1200

28 kW boiler: €1500

33 kW boiler: €1600

In this way, there are boilers whose capacity is much greater than those presented before, which have the possibility of having an installation and supply value of up to €2800.

Take into consideration that if among your projects you are adding the installation of heating radiators, underfloor heating or other heating systems, this constitutes an aggregate cost.
