Discuss Gas or Electric Heating in the Electrical Forum area at ElectriciansForums.net
save loads.......Oh, I love a quiz!
Imagine a workshop, twin brick outside walls, no cavity insulation, concrete floors covered in a vinyl layer, single storey, well insulated ceiling with 300mm insulation squeezed under 22mm chipboard loft flooring. Floor area is 100 square meters, ceiling height is 3 meters, windows and doors take up 10% of wall area, and glazing in these is top notch. What would be the likely requirement in KW to keep this building at 22 degrees assuming the stats keep the heaters on to maintain internal temperature regardless of outside temperature?
Or is that just too much of a guess?
Rethink those figures. Gas is 1/3 of the price of electricity. (Look at your KwH cost on your bills).Hi @pirate. I like the term effective heating as opposed to efficient heating.
I do get what your saying regards cost of installing gas.
Cost off installing gas combi with say 8 rads. £6000.
Or a few electric rads £1000.
If your yearly energy bill is £1200 as electric and by converting to gas it could drop to £900. It would take 20 years to get your money back and then you would probably have to have a new boiler fitted due to age.
Under those conditions electric is more financially viable.
I agree that off peak storage heaters are not efficient, because you have them on when you don’t need to heat the house and controlling the output during the day is nigh on impossible. By 5-6pm when you get in from work there is no heat left so you have to turn on the day tariff electric heaters.
Yep I’ve been on the conservative side there. Gas is 3rd of price, but there is still the electric oven,hob shower, dryer etc....Rethink those figures. Gas is 1/3 of the price of electricity. (Look at your KwH cost on your bills).
Gas heaters will only produce more heat if they have a higher power rating than the electric heater they are being compared to. If you compare a 12kW gas heater to a 6kW electric heater you will get more heat from the gas, if you compare a 12kW electric heater to a 6kW gas heater you will get more heat from the electric heater.as heaters produce more heat when compared toelectric heaters in the same amount of time. Since gasis generally cheaper than electricity, a gas heater has lower operating cost. Electric space heaters are cheaper only when a small space is to be heated at lower temperature settings. i am using instant water heater that is operating on electric power.

Sorry, I meant to put 3 x cheaper.
