Classification of gas water heaters
The list of the best gas models for heating water includes domestic and foreign appliances. They differ from each other in operating power, dimensions, performance and the presence of additional optional extensions.
Divided into two types:
The first ones are called columns and heat only running water. The latter have their own storage tank and serve as storage for a certain amount of water in case of force majeure.
Simple devices with average performance are cheaper, but can serve no more than 1-2 water sampling points. More expensive units are suitable for large apartments, cottages and country houses. By connecting equipment of this level, you can create the maximum level of comfort and convenience in the room without any extra effort.

How to choose the right gas water heater?
When planning to purchase a water heater, you need to decide on its future location. Lungs flow models usually mounted on the wall. This is convenient and practical, especially for small spaces where every square meter counts.
Storage units, due to the built-in internal water tank, weigh more than 40 kg. Most often they are placed vertically on the floor and require free space. Some models are suitable for wall mounting, but their internal tank cannot store much water.
Read more about installing storage water heaters in our recommended article.
The next important parameter is the power of the unit. The lower it is in flow-through models, the fewer water distribution points the water heater can simultaneously serve. In storage devices, this indicator works somewhat differently. High operating power allows you to quickly bring the water in the tank to the desired temperature.
Another significant indicator follows from power - productivity.In weak columns it is about 10 l/min. This is enough to service one hot water supply point. Parallel activation of the second tap leads to a significant decrease in temperature in the entire system.
To ensure the possibility of simultaneous showering and washing dishes, it is worth taking a closer look at units with a power of 20-24 kW. They will be able to supply 13-16 l/min of water resource, and this is quite enough for the parallel operation of 2-3 drainage points.
If there are frequent interruptions in water supply, it makes sense to purchase a storage heater. It will not only quickly heat up the water, but will also help preserve it in case of an unexpected shutdown.

How to choose the right flow-type gas heater for your home.
What is better to buy for your home – a storage water heater or a gas water heater. Expert opinion, advantages and disadvantages of devices.
What the buyer should know about are the main features of domestic gas water heaters:
The best and most reliable gas water heaters provide an uninterrupted supply of hot water to residential and business premises of buildings not connected to a centralized heating system.
They are offered in a wide range on the household equipment market. They are sold at an affordable price, are not afraid of intense operating loads and serve reliably for many years.
Perhaps you were able to purchase a new model of gas water heater? Please tell me if you are satisfied with the performance of the device? Leave your comments, share your experience, ask questions in the block below.
We've had Vaillant in our house for many years. We are satisfied with his work. The activation process is quite simple, you need to turn on the gas using the lever and press the ignition button, then turn on the water. I really like the fact that the ignition is electric, as there is no risk of getting burned. The only thing is that gas prices have now become more expensive and it has become more profitable to install boilers rather than flow generators. To save gas, you have to turn the water heater on/off every time.
Why doesn't anyone talk about the fact that a gas heater is a source of increased danger in the home? And if, God forbid, it fails, then an explosion and gas poisoning may occur. I understand that nowadays all devices are certified and considered safe, but why risk your health and the health of your loved ones once again? In my opinion, although electric heaters are more expensive to operate, they are less risky.
They don’t talk about the danger for a simple reason - there is practically none. No, of course, there is always a purely mathematical chance that something will go wrong and the gas water heater will fail and explode. But if we think in these categories, then we should give up both the gas stove and electrical appliances. Well, what if there’s a short circuit and a fire :)
There is no point in doubting modern gas appliances if you are careful about their installation and operation.And if you want to play it safe, then purchase a carbon monoxide detector, which will signal a possible leak.
