what type of shower can i fit in a gravity system? i want the shower to heat the water.

Yes you can.. but it has to be a power shower (electric shower with a pump) Hope this helped

Hi! You nedd a electric pumped shower ! Regards Daniel

Hi there, You could have either installed depending on your personal preference. You could fit an electric shower, taking a mains pressure cold water feed from the loft, running vertically downwards within the wall to the new unit; This type of shower continuously heats the incoming water, thus never running cold. This type of unit has to be hard wired directly into the consumer unit though, so this needs to be taken into consideration when making a decision as it may be a little extra work routing the cable. Your next option is a power shower. This type looks like an electric shower but has an integral pump which delivers your tank stored hot and cold water at a higher pressure to the showerhead. This type's operation depends directly on you having a tank of hot water to consume; once it's used you will have to wait for it to heat up again to use further. This type can be electrically connected locally, with minimal disruption. Your final choice would be a traditional "concealed" shower mixer type arrangement where the shower controls are embedded within the wall, often with a fixed head above. These are fed preferably via a remotely situated shower pump, and can deliver a much higher pressure to the showerhead. This type also relies upon your stored hot water supply though, so the shower's duration and frequency of use is once again directly dependent upon your storage capacity. The last option is usually only a consideration when contemplating a complete bathroom refurbishment, as re-tiling would need to be completed, although to be honest, unless you would be happy with exposed or boxed in pipework running vertically downwards upon the surface of the bathroom tiled wall down to whichever of the first two types of unit you choose, re-tiling/ patch tiling will need to be done anyway. I hope this helps to give you a clearer idea of what may be involved when it comes to fitting either type of shower; it depends entirely on your budget, your preference/ need for demand, and the scope of works you are willing to undergo to attain the choice that is right for you. Best wishes, Martin.
