【 Weak current College 】 electric floor heating cost estimates

The use of electrical heating costs are easily traced, because electric heating power is rated by multiplying its working time and electricity prices, it's running costs, for example: a building area of 130 square meters of the House, its heating area about 80 square meters or so, we follow 130W/square meter to calculate:

Energy-saving House: when all indoor heating, indoor temperature when opening time 10 hours at 20 ° thermostat, warm the working time of around 3 to 5 hours, low-temperature period 14 hours 14 ° thermostat, warm working hours a day is approximately 1 hour to reach:
130W * 80 m² * 5 hours * 0.45 Yuan/degree (TOU price) * 30 days = $ 702

Non-energy-saving House: when all indoor heating, indoor temperature when opening time 10 hours at 20 ° thermostat, warm the working time of around four to seven hours, low-temperature period 14 hours 14 ° thermostat, warm working hours a day around 1 to 2 hours to arrive at:
130W * 80 m² * 8 hours * 0.45 Yuan/degree (TOU price) * 30 days = $ 1123

This calculation method is moderately on the running cost is in every room open to warm and long-running calculations as a result, normal home if not every room temperature on or attention, or the deployment of high-temperature operation time not that long, then running costs will be lower.

Electrical floor heating and water heating their heating effect is the same, plumbing water is heat carrier, is closed circulatory system of the water heating and space compared to moist, warm and dry space compared to electricity, but they work differently, warm water is heated in the conduct of the work, if a room need heating boiler will enter the working state, hot water from boiler outlet after long pipeline flow to the area that needs to be heated in the current of water arrives at its destination, the reason for the pipeline will heat dissipation to does not need heating space area, resulting in energy consumption and waste, electrical floor heating you can easily work in an area locally, a separate control, energy-saving convenience of flexible and truly want to heat where Thermo where!

In temperature control systems, electrical floor heating of floor heating in each region, there is a separate control, temperature thermostat to a thermostat automatically cut off power supply, temperature low will automatically power up easier, saving energy. Plumbing, each region you can also set the thermostat, but it is to control the boiler and water separator, boilers and water separator and then adjust the size of the fire and through each room of the size of the hot water flow, to reach adjust the temperature of each room. So cumbersome, device control comparison requires a high degree of precision, and a year must maintain a time, or because no precise control, energy consumption increases, which is prone to error, causes the use fees are too high.

Plumbing often say natural gas combustion high calorific value so low running cost is not entirely acceptable, because the burning hot water must be accurate control can save energy, and vice versa, according to experience and real-world data: one about the use of residential 140M2 water warm heat sink, in all of the area are open every day, for 10 hours at 20 ° c room temperature, the other 14 hours at 15 ° c room temperature, monthly running cost about $ 1300 ~ 2000, this amount is the difference between main and insulation and water control accuracy and temperature control system control accuracy is very important for relevance.
