It is true that various brands and models of boilers are available at your disposal. Before choosing a gas boiler for your home, you must take into account the special needs of your space. What thermal power must the boiler have to cover you? Do you need a wall-mounted or floor-standing boiler? Is it worth it to put autonomous heating with natural gas, if the central heating in your apartment building has not been put yet? Also, where will you place the individual gas boiler?
So, here we are, to answer the question: "What gas boiler should I put in the house? ", But also to other questions you may have, before you put gas.
What gas boiler should I put in my house? Everything you want to know!
# 1 Should I install a wall-mounted or floor-standing boiler?
Most gas boilers on the market are wall mounted. This means that they are placed on a wall of your choice and do not touch the floor. On the other hand, floor-standing boilers are the opposite. That is, they rest on the floor and do not need to be mounted on a wall. Admittedly, wall-mounted boilers are smaller in size and more suitable for apartments. As such, they are usually cheaper on the market.
Of course, this does not mean that there are no high-power wall-mounted boilers. In the market you will also find wall-mounted gas boilers that can meet the needs of large spaces, which are, of course, more expensive. Therefore, if you live in an apartment, or a house up to 100 square meters, we would suggest the wall-mounted boiler. For larger homes, it is advisable to consult experts to see what fits best in the space.
# 2 Should I put a conventional boiler, or a condenser?
Until recently, you had to choose between buying a conventional boiler, or a condensing boiler. However, today the installation of a gas system is done only with a condensing boiler. Therefore, there is no dilemma for your purchase here. But what is the reason that condensing boilers prevailed? The condensing boiler clearly answers the question of what gas boiler to put.
The reason is that it offers energy savings and as a result, money savings. Compared to conventional boilers, the condensing boiler offers more useful energy in the space, with the same amount of fuel. Also, the exhaust gases it emits into the atmosphere are less harmful. In the long run, you will realize that you enjoy not only more heat in the house, but also greater savings in heating costs.
# 3 Should I put a cast iron or steel boiler?
Many people wonder, before buying a boiler: “What gas boiler should I put, to last for more years? “. The durability of the gas boiler is directly affected by its construction material. The steel boiler is usually cheaper and lighter than the cast iron one. Nevertheless, the cast iron boiler seems to have a much better efficiency, when operating with gaseous fuels.
Thus, since natural gas is a gaseous fuel, the cast iron boiler should be more suitable for its use. In addition to its good and stable performance, the cast iron boiler seems to have a longer lifespan, reaching up to 30 years. Sure, it will cost you more in the market, but you will have it for more years and you will pay less for maintenance. For us, it is a good answer to what gas boiler to put to have a long-term profit.
# 4 What thermal power should the boiler have?
The rated thermal power of the boiler is the promised efficiency guaranteed by the manufacturer for the boiler, as it is in continuous operation. This efficiency is expressed in kilowatts (kW). Many times, in the trade we meet the promising efficiency of gas boilers in kilocalories per hour (kcal / h). Using kilocalories, we can calculate the kilowatts. The more kilocalories per hour, or kilowatts per hour that the boiler can support, the more space it can heat.
Thus, a relatively small house can be heated with a gas boiler without much power in kilowatts. In contrast, a large house needs a boiler with more power. Let's look at some indicative numbers to answer what gas boiler to put, depending on the size of my house. For houses up to 100 square meters (m2), boilers up to 24 kW, or about 18,000 kcal, are usually sufficient. For houses of 100-150 square meters, boilers with a power of around 20,000 kcal per hour are selected. Finally, boilers with a power of around 30,000 kcal, or 35 kW per hour, are selected to heat a house of 150-200 square meters.
The higher the power of the gas boiler, the higher its price, as you understand. However, it is recommended that you consult experts to choose exactly the power your home needs. If the boiler you buy is economical, but not enough to heat your home, then what is the point of buying it?
# 5 Should I put central or autonomous heating with natural gas?
Today, more and more people are realizing how much benefit gas combustion has compared to oil combustion. Thus, many apartment buildings are replacing the oil boiler with a gas boiler. Probably a factor as to why they're doing so poorly. However, changing the central heating system is not a decision you can make on your own.
Everyone must agree. If not everyone agrees, then you can, in any case, install an autonomous heating system with natural gas. If you follow the legal procedure, you will stop participating in the expenses of the central heating and now you will only be concerned with your own system
# 6 Should I place the boiler indoors or outdoors?
The individual gas boiler is used when you want to put natural gas in your home, with autonomous heating. This applies to apartment buildings and detached houses. As long as it has a built-in gas burner and there is no problem. There are 3 common places where an individual boiler is usually installed. These places are the balcony, the kitchen and the bathroom.
Obviously, we try to place the boilers in a non-central point, because they are not the most beautiful decorative elements. In the kitchen, or in the bathroom, the boiler can be cleverly hidden in large cabinets. This way, it will not look and will not disturb your aesthetics. As for the balcony, it is mounted on the wall (ie if it is wall-mounted) and bothers as little as possible. If you live in an apartment building and do not have a very large balcony, then maybe it would be good to store the boiler inside the house.
# 7 Will the gas boiler provide me with hot water?
If you install an individual boiler, in addition to heating for the winter, you will also enjoy hot water. Too many gas boilers also offer the possibility of producing hot water. A heat exchanger is enough for hot water. In fact, it is a rather advantageous option, as the cost is usually lower than the production of water from a traditional water heater. Of course, you can control at any time what your gas boiler costs you. Each boiler is connected to a meter, which has an indication of the gas consumption of your home. Depending on what the meter shows, you pay the corresponding amount for heating and hot water.
