Which is better – Gas or Electrical?
Electric has the bigger storage tanks. If you have quick recovery, it can be more expensive. Some houses don’t have gas, so they’re pretty much stuck to the electric system. If you have gas, it’s more efficient. The instantaneous units are a lot smaller and take up less space. They only turn on when you turn a hot tap on, so I definitely recommend if you have gas to switch over to the instantaneous.
