Yes, but you need to check with your supplier if your electric shower or combi boiler can accept a pre-heated water supply. Its not a hot pre-heated supply (such as with a solar system) but more of a warm pre-heated supply around 28C. Many brands of combi boilers and electric showers are suitable for this. If you are using it with an electric shower then choose one with manual power settings, such that the power consumption can be turned down to compensate for the pre-heated incoming water. Alternatively some people decide to achieve much higher flowrates than would normally be possible with an electric shower, especially in the winter months.
