Hi Zoom,

At risk of jumping off track a little, here is my anecdotal evidence base on my experience of electrical boilers. I feel it ties in with other recent discussions about the current trend for going all electric.

I tend to agree with the view that electric boilers should be installed with caution. I find it terrible that people are being frightened into making these decisions without the full knowledge of the impact it will have on their wallet.

 

First, a bit of background to the construction of the property:

 

The house was a small, converted brick barn attached to another barns/cottage. 

It consisted of a very small upstairs bedroom, a small cosy living room, small hallway and stairs. The kitchen was in a 3 metre by 5 metre conservatory which was unbearable in the summer and cold in the winter.

The home had wet electric fed radiator heating and a single shower. Although it had been lived in for years by an old lady, the place was refurbished by the new owner/landlord in 2019 so the boiler was new.

Heat-loss wise, the windows were double glazed but old. The same goes for the conservatory. There was little scope to add much insulation as the ceiling was vaulted in the bedroom. The walls were single skin 9” brick. The property was a little draughty due to the conservatory.

 

She, who must be obeyed, likes a toasty warm house, and, it was.

 

The manual said the boiler was 14.4kW. There was no gas supply.

 

I was testing a data logger in February this year, this coincided with the coldest period of the winter when the temperature didn’t get above zero.

The kWh usage for the boiler between 10th Feb to 15th Feb was 672.3 kWh.

The total bill for electricity, for one year was £5k.

I have attached the stats from Powerpoint Pro below:

Thanks very much Andy1 and Andy 2 and all others. Very helpful.
