Best Tankless Gas Water Heater: Buying Guide 2020

How much does a gas water heater cost?

The cost of gas water heaters can vary based on a number of factors, but prices range from 60-80 dollars of the models available in the low-priced product range, which however have a minimum flow rate, up to 1,500 dollars and more than water heaters of the higher end.

Gas water heater, how many liters per minute?

The flow rate of a gas water heater is indicated in liters per minute and obviously influences the yield and the ability to meet the needs of domestic hot water based on the number of people who make up the household and their consumption habits.

The models of 6-8 liters per minute, for example, are sufficient for limited and occasional use, as happens in the service bathrooms of public premises for example. For a family of two or three people, a model of 11 liters per minute may be enough, while if four people or more live in the house, then it is better to focus on those from 14 liters upwards.

How to mount a gas water heater?

The assembly of a gas water heater is extremely simple, since even the models with the largest capacity have the advantage of being decidedly compact and light, and therefore a few tools are enough to fix them firmly to the wall.

Even the number of connections is minimal, in fact there are usually only three pipes to be connected: the one for the gas supply and the two deputies for the water inlet and outlet. A separate discussion, however, is represented by those models that must be combined with a solar thermal system; in any case it is advisable that a specialized technician take care of the assembly and also of the installation of the exhaust system.

How long does a gas water heater last?

The duration of a gas water heater, as for any other appliance of this type, depends first of all on its correct use. The manufacturer’s warranty, depending on the case, covers a period ranging from two to four years, but the duration can even reach ten years and beyond if you are careful to follow the right procedure every time you turn it on, and you it periodically cleans sensitive parts.

Also in this case it is advisable to let a technician take care of it, so as not to lose the warranty on the product and not risk causing malfunctions due to inexperience.

What is the price of a good product?

You always want to be able to buy the best product at the best possible price. Of course, this also applies to the purchase of this product. Everything should always have a low price and not cause additional costs.

Is this what we want. But quality now comes at a price. Buying cheap, we often buy double or triple again. Therefore, it is important to give the different prices for each item. With each product that we show you, you will always find the current price, although this may be different at times and may not have increased transportation to the home.

Enjoy the money a little more and enjoy the product in the long term. Buying a good quality product will please you in the long run, which is not always the case with cheap bargains.

How was the comparison made?

User experiences offer us different opinions. If the buyers or users, at first glance, misjudge the product, it means that they did not like anything, since the size, cut or even color was not suitable for them. However, these so-called 1-star reviews often contain only the frustration the user has had.

Maybe you just made a bad purchase and it just wasn’t right for your ideas. To avoid this, we always recommend that you read the reviews carefully. If not, stop by a store around the corner that also offers this item. There you can take a closer look and form an opinion. You will have to follow our advice.

Do you have questions?

Before buying a gas water heater you need to clear up many open questions in advance. Comments from other buyers will help you, investigate in a specific forum on the subject . Are there other things to consider besides the noted product details? The color is correct, as you can see in the small picture in the online store? How does the product behave after washing?

These are all the questions that, as a consumer, you will surely ask yourself. Naturally, the brand’s fashion producers also want to get a high turnover of their products. The bigger the brand, the better the products. But of course there are also many small and unknown brands that offer good quality.

Here you have to pay attention to the additional purchase criteria. Finally, of course, the price is also decisive. If the price is not simply proportional to the quality, it is advisable to buy another product.
