We're about to renovate our old house to rent it out. It will have three bathrooms when its finished. The house currently has a combi boiler, which I'm aware isn't great if two people want showers at the same time. This wasn't a problem for us living there but probably will be for tenants when there's 5 adults all trying to get ready for work in the mornings so I will have to make some changes to the current set up. There is no space for a hot water tank/megaflow anywhere in the house unless we put it in a bedroom (definitely not ideal) so I'm looking into other options than system boilers. As I see it, our choices are either a new storage combi boiler (which will be about £2000 plus installation), or changing at least 2 of the showers to electric showers (about £350 each plus installation). Our water pressure is good. I can't find out very much info about storage combi boilers anywhere so I'm struggling to work out whether this would be a good option and whether they would potentially cope with 3 showers and a dishwasher running at the same time (as a worst case scenario). I'd love to hear some thoughts on the options or whether there's another idea I've missed?
