We have a barn conversion in the Perigord Vert and hot water to the kitchen and also to a shower and washbasin is provided by a Chaffoteaux et Maury gas heater that runs on bottled gas and does not have or need a flue. It is very efficient, but not really man enough for the job. It certainly won't stretch to heating the water in a planned second shower room! If the holiday home was in England, we would fit an instant electric shower of say 8kw, but our supply at the barn is "option base, puissance 3kw". I believe this can be upgraded, but by how much? The supply in the little hamlet is by overhead cable and we presently run the usual white goods and 2 or 3 1kw heaters in the bedrooms - not on full power, of course! We do not want a "wet" system with oil or gas central heating. We go the barn when we can, but it stands empty most of the time and we drain down in the winter for safety reasons. Does anybody have any bright ideas or suggestions? Ideally, we would like to introduce two new showers and preferably instant hot water, leaving the gas heater for the washing up only.
