MJA pārkalkulēju doing well and meet the 1-liter water heating by 1 degree in 4180 Joules of energy

All around talking about inflation. As has anyone I've encountered with different prices. Vot receive a monthly bill for me as a mathematician came to mind izrēķiniāt - which is more profitable - in Riga Heat delivered me hot water (at a charge is levied separately for water and for water heating) or the electric heater (or Boiler)
Riga Heat (Pļavnieki Dzik "Jubilee") heats the water to me about 2,95 Ls / M3 (According to the bill for April) One cubic meter = 1000 liters, a family of hot water consumption on average per month = 7 M, hot water inlet temperature today: +44 ', the cold water inlet temperature + 4'C superheated steam properties = Difference 40'C (cold water must be warmed to 40 degrees to achieve the same temperature and the same place - the tap vannasizstabā as shipped Riga Heat) It all concludes = Ls 2.95 x 12 months x = 7M3 247 Ls / year
Heater Price: 130 Ls, heater max capacity: 1.8 Kw, Boiler capacity: 150 liters Heat the water to + 75'C need 4.5 hours. The trail we warmed in 150 liters of + 40'C, then it will be in proportion to 60% of the time or 2.7 hours.
In addition: Taking into account that the purchase of the heater, the heater to such consumer 7M3 monthly pay of 2 years and 5 months. If you find a better heater as well, when the warm water consumption becomes larger (family or simply increase will become tīrīgāks) then even faster.
I nelobēju any of the electrical superheated steam properties industry ... rather, I would be pleased if an electric heater is used instead superheated steam properties of the ground heat exchanger, pumps, in principle, superheated steam properties lead to even cheaper hot water per cubic meter.
If the water heats of 2.95 Ls / m3, it is still normal, but what if we can tell, Carnikava, the tariff is already 4.75 Ls / m3 - May Monthly?!
We Valmiera is as precious as life in Riga. Water heating 4:57 / m3 + cold water cube paid 1.26Ls / m3. So one cube of warm water we paid 5.83Ls / m3, and the water temperature output point (from the tap) is the only 48'C, which means abnormally high hot water consumption.
After the last information Riga City Council plans next year to raise tariffs in warm water for about 2 times ... as well as energy prices piesauistīt! Vot ...
Sāksism if the calculations are done izmantojt laws of physics turns out that 1 m3 of water heating by 40 degrees needed 47 kWh. Thus, the 150 l Warmer takes 7 kWh instead of the author indicated superheated steam properties 4.8 kWh.
MJA pārkalkulēju doing well and meet the 1-liter water heating by 1 degree in 4180 Joules of energy or 16.1 WATI. A total of 150 liters of heating system heats will take 6.96 kWh and the price is 03.31 Ls (stick to the principle of ceteris paribus) and in 278 Ls, if boilersi superheated steam properties and 247 Ls, if Riga heat.
Your statement was essentially okei, the only mistake was that you believed in the ability to heat the boiler water from Gradius 4 to 75 degrees to 4.5 hours. The aggregate technical indicators on the Internet in general have different example bode http://www.thaiswai.com are promised heat the water to 65 degrees for about 4 hours and 50 minutes. In addition, no do not do what is the initial temperature of the water.
in our case Q = 4186 J / KGC 150kg * * 40C = 25116000 J Now transform the Joule Kilowatos 1 J = 2.77777777777778E 07-kWh, or in our case, 25116000 J = 6.98 kWh (which then also replace your 4.86 kWh and nothing else changing meet ~ 278 Ls boiler costs. superheated steam properties
The truth is that no matter how prakserāda then have just mounted boiler (water heater with a capacity of 100l and power 2kW heater) cold water up to 75 degrees and heats up in reality no more and no less than by 4h and 10 min, then varvienkārši and easy to figure out how much it paid it hot water
Однозначно электрический superheated steam properties нагрев по сравнению с сегодняшним тарифам от Rigas Heat (1.70 за циркуляцию и за 4.16 куб 1) в примерно в 2 раза выгоднее. В среднем от 2.30 до 2.74 за 1 куб. нагрев до 40 градусов (разница 25 градусов с 15 до 40).
And yet the thing that you can not simultaneously be used to heat water and other high-powered equipment, such as an electric kettle.
Поставил 30L (4 человека до установки потребляли superheated steam properties максимум 3 куба в месяц (обычно 1-2) горячей воды это значит 100 литров в день, а этот бойлер в день нагреет не меньше чем 30 литров за час) В самый раз и не нужно нагревать до очень высоких температур 40-43 градуса в самый раз бойлер с хорошей изоляцией потребляет и объёмом в 30 Литров потребляет в режиме ожидания 0.57kW superheated steam properties / 24H. http://www.aeg-haustechnik.ru/catalog/electric-water-heaters/accumulative-wall/comfort/
is strongly in advantageous in a boiler, I have already 3 years and cost zinjaa, as well as the house no hot water (for various reasons after) me he always is, and above all, that the boiler can be programmed to be heated when needed and for how long needs, and to the desired temp., whereas electrical well without wasting
It is not true that one can not simultaneously operate superheated steam properties the boilers and other equipment, -I was both a washing machine and cooker hood, television, electric, oven, computer, etc. pim. circle
