Bathrooms and RSG?

lanners

We are hoping to get a new bathroom fitted in the next few months and one of the companies that came round today said that we need an RSG? RSD fitting in the bathroom because we have an electric shower in there and we don't have a combi boiler. Does anybody know what he's talking about?

Thanks

Could be an RCD (residual current device) or even an RCBO. Basically an electrical safety device.

You're welcome !!

I presume they mean that you need an electric shower because you don't have a combi. If you had a combi you would have hot water 'on-demand', ie.- as soon as you turn the hot tap the combi would heat the water.
You don't 'need' an electric shower but depending on your central heating/hot water system you would either need to have your immersion heater on, or hot water system on to get hot water. An electric shower is just more economical (I think!)
If you remove your electric shower and have a mains water shower you wouldn't need a RCD.

Not necesserily, shower pumps designed for use in zone 1 are not require to have an RCD under BS 7671. Often shower manufactures recommend an RCD is used.
