Electric Boilers

First, we need to talk about the differences between the two types of heaters available on the market. The electric boiler has a reservoir in which water is maintained so that it is continuously heated to be used immediately in case of a shower or other needs. For this, however, it must always be connected to a socket so that the sensor detects each time the water drops below the set temperature and then triggers the water heating command. If you are looking for one, you may need to get a boiler from 2 RED.

Thus, the energy consumption is higher for this boiler. It also requires a rather large place in the bathroom, which can be an inconvenience for some. The advantage is that hot water flows at a constant flow rate. The downside is that you may wake up halfway through the shower to stay warm and then wait for an hour.

Gas Water Heaters

There are also instant liquefied petroleum gas (LPG) instances, which solve this problem. These are, however, much more expensive and the cost of the gas is added to the costs. Those who do not need a large amount of hot water and who do not have a budget to buy a power plant can choose a heater. The system is simple to use and has a relatively low cost.


Overview of Tankless Water Heaters

are tankless water heaters worth it

A tankless water heater, as the name calls it, warms water much faster, in real time. It does not need to operate continuously, so that in total it could save on electricity consumption. On the other hand, if a boiler can support both the tap through the bathroom and the kitchen faucet, when selecting the instant, it is necessary to mount one in each room.

Also, many users have written online forums that they are disappointed that more water is not hot enough. There are all sorts of solutions, such as choosing a higher power device or ad hoc tricks such as lowering the water flow, which would lead to better heating. The bad part is you have to get used to a weaker flow. 

In general, there are two types of tankless water heater, namely electric and gas tankless water heaters. Want to know more about the difference between these two, check out electric vs gas tankless water heaters.


Investing in a Tankless Water Heater

Electric

The electric tankless water heaters heat the water in a much shorter time than a boiler. It has the advantage of having a low energy consumption than the boiler. If you want hot water both in the bathroom and in the kitchen, it is recommended to install a single one in each room as the heater does not handle the flow of two taps. The heater's running costs are higher than a gas instantaneous.

Gas

This type of heating has a heat exchanger and a burner. This water heater is of small size and is used only for water heating, which is not capable of being used in radiators.

It is advisable to choose a gas snapshot to provide electronic control instead of a waking flame. In a gas heater, always choose a product that is in a higher energy efficiency class (A or A +).

Tank in Tank

The tank in tank structure is the latest technology on the market and focuses on two components: the base of the boiler, called the shell, and the internal balloon, which is made of steel and has the tank function.

The main advantage of this type of boiler is power, followed by the reheat function, which has a low consumption and is performed in a very short time. It also offers a heat transfer as fast as possible, and the heating surface is much higher than other models.

Bivalent Accumulator

This type of boiler is designed to replace the classical boilers on wood or gas to meet the requirements of high capacity. It has a high flow rate and very fast water heating, with bivalent accumulation, which involves two heating sources.

Hot water flow

When choosing a heater, you should consider the hot water flow that it can provide. The best heaters can heat up to 10 liters per minute.


How do you adjust the water temperature?

A tankless water heater must allow the temperature of the water to be adjusted, as it also determines the consumption. It is not necessary to set the heater at the maximum temperature but at an acceptable level for each user.

Setting the temperature is done by a potentiometer, so check if there is an instantaneous source of hot water.


Other important features for the best instant hot water

For a temperature view, choose a heater that comes with an LCD display that indicates the heater's status and the number of hot water Celsius. When you buy, check if there are special mounting requirements (depending on where you are installing it) and if the heater benefits from the company that has a warranty of at least 2 years.


Placement

The tankless water heater can be mounted in a kitchen or bathroom in a vertical or horizontal position, depending on the user's needs. In the kitchen, the heater can be placed over the sinker faucet or even below if there is not enough space.

In the bathroom, the heater can be mounted on a fixed stand, on the wall, above the bathtub or near the shower.


Hot water instant installation

Always, for both types of instantaneous heaters, it is necessary to install them by using authorized personnel’ help. 


Fina​l Thought

Choosing the best tankless water heater needs to be done according to the needs of everyone, the budget available and the area you live in. For example, in mountainous locations or temperatures below 0 degrees Celsius, it is difficult to use an electric heater as there is a risk that the water will freeze on the supply pipes.

Depending on the number of points that use heated water, i.e. if you only need a boiler in the bathroom, or only in the kitchen; or in both rooms or more bathrooms, you can choose the appropriate size, capacity and pressure. Depending on the boiler power, which is, the total resistance of the boiler, you can choose in between 1 and 3 kW. This parameter shows how fast the water heats up, but also how much the boiler consumes. The more resistance you choose, the higher your consumption will be.

So, if we talk about a single room, the tankless water heater could do its job very well. From here on, the size increases depending on how many points of use the boiler is connected to.

So, if you ask me again are tankless water heaters worth it? Definitely yes and you should give it a go too.
