两种用电和用gas的方案，哪个更省？

1.电用Enmax的,气用direct energy regulate的浮动;
2. 电和气都用Enmax的,电fixed,便宜些，但气贵，不过有＄100返现金,

电热水炉和气热水炉都需要电的，所以为什么安省雪暴导致断电的时候会有很多家庭无热水供应。

In Winnipeg, the average life expectancy of a gas water heater is between 6-8 years while the average life expectancy of an electric water heater is between 8-10 years. Therefore, the advantage is given to electric water heaters in the category.

It is important to choose the proper size of electric water heating elements and storage capacity based on your hot water needs.

, }5 W7 T8 T9 c* d! mCustomers who do not install sufficient storage capacity must use larger electric water heating elements to ensure an adequate supply of hot water is available. Oversized heating elements cause spikes in your electrical demand, resulting in costly demand charges that often exceed energy charges. In contrast to electric billing, natural gas does not have demand charges.

Electric water heaters are very energy efficient because all of the energy entering into the heating elements goes directly to heating water. Heat energy is only lost through the walls of the storage tank, accounting for less than 5 per cent of the electric water tank's annual energy consumption.

Natural gas

Unlike electric systems, the efficiency of natural gas water heaters may vary greatly. The amount of energy transferred to water from burning natural gas depends on the efficiency of the gas burner, the heat exchanger, and the venting system. Natural gas water heaters have three different levels of efficiency.

It is important to factor energy efficiency into your purchase decision as it affects your initial capital and ongoing operating costs. Energy efficient models may cost more initially, but reduced operating costs will provide savings over the system's lifetime.

电用Enmax的要$100现金，气用direct energy regulate浮动。

肯定是气便宜了，要不然房屋取暖就该用电了

哦，谢谢，似乎有的方式做饭的炉子是用气的。
