I've got a Worcester 24i Greenstar boiler and just being on, it
dissipates around 10W. Normally this wouldn't bother me too much but
it's on 24 hours which is 240W everyday and at 8p/KWH costs 1.92p a
day or £7 a year. Not much I'll admit but I'm sure the deisgn
engineers could have got the power dissipation down to less than 1W
when the bolier is doing nothing and then fired up the rest of the
circutry when it needs to.

Likewise, my washingmachine, dryer, cooker oven, dishwasher dissipate
15W together for just being pluged in which is no big deal providing
they can be switched off easily and don't need dismantling of the
kitchen to get at the switch which the burke that installed my kitchen
forgot about.

Thankfully I have a Hotpoint fridge which takes virtully no power on
standby because it's isolated from the mains via a power relay which
switches when necessary.

Don't forget that the energy will be released as heat into the house, so
it reduces its own workload a little ;-)
