Gas v electric kWH?

[mr brightside]

What's the point?

Get rid of salt in the winter and crap that builds up in the arches and stores water.

So if i want to do the washing up, do i boil the kettle or get hot water from the combi?

As regards the kettle or combi boiler question, I suspect that there are too many variables
to give a reliable answer.

If only one kettleful of water will suffice than I expect the kettle will be cheaper. For larger volumes the gas combi boiler will probably be cheaper.
I use a 1 kw wall mounted electric water heater for washing up.

I've been looking for an appropriate house in Scotland to retire to when the time comes, and I've noticed that whenever a house has electric-only heating, it gets just one star (out of five) on the EPC report. Even oil-fired heating does better than this, and gas boilers seem to be the most eco-friendly of all. Even air-source heat pumps don't seem to improve matters.

I wish I understood better what the best way is to compare the different ways of heating a home. Insulation is a given of course, but what's the most energy-efficient form of heating at the moment, and what's the cheapest, and what's the most eco-friendly (least emissions)? I can't figure it out. I thought air-source heat plus solar PV should be best, but you lose the PV just when you need the heat, and few people have the money, space and neighbourly goodwill for a wind turbine.

i seem to remember that electric-only homes get low EPC scores.
The calculations seem to be outdated.

I read that the EPC is a measure of cost saving rather than a carbon saving one so the higher cost of electricity is the major factor.

Washing salt off in the winter can be useful. We take the ancient RenewableMobile to the car wash about twice a year if there's been ice or snow.
