I miss the times when every light fitting was the same (one size, bayonet style).
I don't know how many different types and sizes of fittng we have. It's a pain replacing bulbs now. I preferred the light from the old incandescent bulbs too and if they give off a little heat, well living in the temperate zone we need a little heat after dark.
- stuaxo 10y agoThe light is better, but the heat is usually not where you want it.
- barking 10y agoWon't it amount to the same thing as a heat source anywhere else in a room, with convection and radiation?
- TheSpiceIsLife 10y agoModern heat pumps are three to four times more efficient in their use of electric power than simple electrical resistance heaters.[1] I have a 7.1kW heat pump, it uses a little over 1.79kW of power generate that heat, so a thermal efficiency of 3.96:1. Any light bulb, whether it's incandescent or CFL or LED produces heat a 1:1 thermal efficiency. 1. https://en.wikipedia.org/wiki/Heat_pump https://en.wikipedia.org/wiki/Heat_pump
- brianwawok 10y agoDo many people have heat pumps? Most people I know in the Midwest make 100% if heat from burning natural gas. So in the winter not a huge loss (just the delta on cost between electricity and natural gas). In the summer obviously you pay double..
- TheSpiceIsLife 10y agoHeat pumps / reverse cycle air conditioners are very popular in Australia, but the temperature here is fairly moderate, even in Tasmania where I live there are few places where it's below zero for more than the over night period. Heat pumps don't work so well sub zero.
- jschwartzi 10y agoMany of the old incandescent bulbs have been replaced with halogen bulbs with filters so they produce similar light. But they're so much more efficient that I can no longer rely on them to warm a room at night during the fall. Also they burn out in less than a year.
