I have a small caravan site and holiday cottages in France and need to update the hot water system. At the moment I have an electric immersion heater supplying a 4 bedroom en suite house with 3 more showers, this is obviously not enough. I am looking at using my immersion heater just for the house and I am looking to install something else to supply the other 3 showers for the caravan shower block. We don't have mains gas, bottle only and don't have a oil, so an oil fired boiler would be expensive. Is there a boiler that would run off a gas bottle available that would be capable of supplying potentially 3 showers at a time, or would I be better of just installing another immertion heated tank.

Any suggestions welcome,

Dave
