Shower/Immersion question
I have an electric shower at the moment that trickles out quite cold in winter. I am wondering if I could run a power shower from the economy 7 immersion water heater. I never have the emersion on at the moment as I always have a shower from the electric shower and wash up using the dish washer. I have no need for hot water so if I used it, it would only be used for a power shower once a day (there is only one person in my flat). The immersion heater is quite large and can easily fill a bath full with its hot water only (so enough for 2 baths at a normal temperature mixed with the cold). The heater is right next to the shower/bath so would be lower than the shower head (does that mean I would need a pump?). Could I run a shower good shower off this system or should I stick with an electric shower and just get a higher watt one? I do not want to spend loads on a combi boiler as I would only use it for a shower and there is no venting wall near also. So all I want to know is can a power shower be installed into this setup and what stuff would I need (pump etc?
