Has anyone got or had experience of electric central heating boilers?

My brother had one in the flats above the take-away he owns. It was insanely expensive to run for the amount of hot-water they needed in the main kitchen. Replacing it for a gas boiler paid for itself in about 3 months.

 

only fitted one ,in a granny annexe.Really simple to fit .it runs with an invented cylinder and under floor heating.Fitted about five years back.The owners have oil in there house and no gas nearby.I seem to remember it was heaters sadia.Predictive texting contained within this post

 

That seems a bit steep for normal house use of an 8 rad circuit.

I normally say a boiler runs 8 hrs a day for heating and water in winter. Some days more, some less so 8 is a good average. Then for the remaining six months 2hrs a day for hot water.

So .8pr hr x 8hrs = £6.40 a day in winter.
£6.40 x 182.5 days (winter) = £1168

Assuming it's only doing a third of the work for hot water.

0.26 pr hr x2hrs = 0.53 per day in summer
0.53 x 182.5 = £97.33

£1168+£97.33= £1265 per year. I think the cheapest fixed gas tariffs are about £800 a year. So basically it's about 50% more expensive to run than gas.

Bit of a guesstimate really. See what the other heating monkeys on here think.

 

Obviously that's not a combi. I've factored in the two hours a day to heat a hot water cylinder

 

That does sound well suited for your needs then. Especially if it does modulate down which I'd be amazed if it doesn't.

 

£150 you can't really go wrong!
