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;

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。

Water is most commonly heated by natural gas, where available, or by electricity, propane, or fuel oil where natural gas is not available.

Hot water can be supplied directly or indirectly by hot water storage tanks, tankless water heaters, space heating boilers, or by a combination of these systems.
Electric

: h7 P+ b5 j  y- x: g3 TIt is important to choose the proper size of electric water heating elements and storage capacity based on your hot water needs.

Customers 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.

. V; N8 ~+ s/ `% K: VElectric 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.

The most efficient electric tanks available on the market today are insulated with 75 mm (3 inches) or more of rigid foam insulation, which significantly minimizes heat loss.

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.
