Hot Water: What is more profitable, boiler or central water supply?

This is a topical issue, especially after hot water rises in price once again, or disappears altogether in the summer while preventive work is being carried out. And in general: what is more profitable for the consumer? Let’s compare. Calculating the cost of hot water in the apartment.

Calculating the cost of hot water in the apartment

If more than one person is registered in the apartment, the installation of a hot water meter will save a lot of money every month. Boiler to replace the centralized hot water supply

Boiler (from the English. Boiler – boiler, kettle) – an electric device for heating water collected in the tank. Instantaneous water heaters and boilers that run on other types of energy are not considered in this article. In essence, a storage boiler is a tank with a built-in heating element that uses electricity to heat water to a given temperature.

The efficiency of modern boilers is about 96%. All this is clear. The definition does not state that the device not only heats the water to the desired temperature, but also maintains this temperature as a thermos, but with the possibility of further heating. How long the water stays warm depends on the quality of the insulation.

The devices offered by our company retain heat during the day and use only 1-2 kWh. per day. It turns out that heat, but not used water remains warm for a long time. And you save money because reheating is not required. The cost of electricity is the main component of the cost of hot water from the boiler

The cost of electricity for household consumers with a conventional meter is: $ 0.9 for the volume consumed up to 100 kWh, $ 1.68 for the volume consumed over 100 kWh. Multi-tariff meters will help save the Residents to have the right to pay for the consumed electricity, using differentiated tariffs. They depend on the time of electricity consumption.

Accordingly, there is a three-zone tariff: night, semi-peak, and peak with different values ​​for each of these periods. The second option is a two-zone tariff, which divides time into night and day from 7 am to 23 pm. To pay at a reduced rate, you will have to install a multi-zone or multi-tariff meter. Such a device will be delivered to you by specialists of Kyivenerho customer service centers. You will find the addresses of these same centers on the official website of the organization. There you can order not only the meter but also the service.

What do you get with the meter? It will be delivered to your address. Unseal and remove the old meter, instead of supply and connect a new one. Parameterize it for two or three tariffs – as you wish. The new meter will be sealed and you will be left with all the necessary ones. documents. In new homes, there are usually digital meters, they are not removed but only reflashed. Then all that remains is to renew the existing contract on new terms – and this will be your confirmation that now the energy used is accounted for at a differentiated rate. At this rate from 23:00 to 7:00 for electricity, you pay half the cost, at other times, at the standard rate.

How much will it cost to heat water with a boiler?

Output data for calculations: 1) The cost of 1 cubic meter. m of cold water is $ 8,436. 2) Boilers with a capacity of 1.5 kW are available on the market. up to 3 kW. According to our statistics, the most popular models of boilers with a volume of 80 liters and a capacity of 1.5 kW Consider the cost of 3 cubic meters. m of hot water per month obtained by such a boiler when using a conventional electric meter.

However, if you have a multi-tariff meter with a 2-zone tariff and your boiler works from 23:00 to 7:00, then 3 cubic meters. m of hot water will cost you as much as $ 147.43. (this is already with the cost of cold water). These figures are approximate and depend on many factors, which in principle will not change it much. Conclusion: we recommend buying boilers of the maximum volume to heat a larger stock at night at a reduced rate.

It is also advantageous to use socket programmers. the programmer physically turns on the boiler after 23.00 and turns it off at 07.00, so the boiler should be chosen in such a way that you have enough hot water for the period of the increased tariff for electricity.

Advantages of centralized water supply

There are no additional costs for the purchase of a boiler; It is not necessary to allocate in a bathroom a place for installation of the device; Save time and money on purchasing and installing a multi-tariff meter (if you don’t already have one). Disadvantages The water temperature rarely corresponds to the declared value; Annually, hot water is turned off for preventive tests.

The shutdown lasts from two weeks to three to four months. Advantages and disadvantages of water heaters Conditional shortcomings of boilers are limited to the time of installation of a boiler – it is necessary to spend 2-3 hours for installation; as well as the need to allocate space in the bathroom or toilet, where you could put the device. However, the design of modern boilers allows you to make them part of any interior without violating its integrity and harmony.

The advantages are obvious: you can choose the desired temperature for heating water, and use the remnants of warm water during the day without having to turn on the device again. If you have cold water and electricity, then hot water will always be, and even cheaper than a centralized supplier.

You have to choose, the choice is always:

1. Continue to depend on utilities, hoping that another “pipe burst” will not happen.

2. Spend absolutely acceptable for most families and little time, buy a boiler and get hot water whenever you need it. If you decide to choose a boiler, the managers of our company will provide you with all the necessary advice and help you choose the most suitable product.

And technicians will qualitatively and quickly install the device in your house, and it will serve you for many years. Finally, recall that most modern appliances (washing machines, dishwashers, boilers) allow programming of start-up time. So you can turn them on after 23:00. Nothing complicated, but you will be pleasantly surprised by reduced electricity bills.
