Temporary replacement boiler - water heater?

going2die_rich

My friend's boiler has gone so she's got no hot water. She's on long term sickness so can't afford to replace it (someone's been out to look at it and said it's beyond repair). She is likely to be able to get benefits through some government scheme in having it replaced but it'll be at least 8 weeks maybe more till that occurs.

She's okay in the fact that it's good weather now so stopped using the central heating weeks back and does have an electric shower. The only real problem for her is washing dishes with cold water for the next 2 months. Not impossible to do, but a bit of a pain with her not being well to begin with.

So are their any temporary measures such as a portable water heater or something I could buy for her (up to around £100 or so) - she's a good friend so I'd like to help her out?

She really just needs something to just warm up a bit of water she can use for the dishes (no space for a second hand dishwasher - which was my first solution), which can be placed by the kitchen sink. She's using the kettle at the minute but that’s always scolding hot and is no doubt costing a fortune to heat up water to that temperature, especially if it continues for the next few months.

Any help would be greatly appreciated. Preferably a solution that is portable and requires no installation since it is just for a temporary fix.

Thanks,
