I'm considering how to provide some heating to an extension. Off the
kitchen, it's a utility room with shower room beyond, total area about
7m x 2.5m.
There is CH to the kitchen but I haven't yet determined whether it can
be extended to provide radiators.
I'm looking at electrically-powered underfloor heating (area will be
all floor tiles). However, as the roof gets a lot of sunlight I also
wondered if solar panels used to run warm water might be a viable
alternative.

Any observations from anyone who has done something similar?

Electric costs around 3x gas to run.
Flat plate solar space heating is far cheaper than costly water
heating systems. This is the one form of solar that has very
reasonable install cost and pays back well. See alt.solar.thermal.
