Electric costs about 50% more than natural gas.
== == As with most things, it simply comes down to money, and space. A larger PU resistor will guarantee a more solid output, but they cost more, take up more space, & waste more energy by creating more heat. So, if you have a small box with other heat producing devices, additional space and/or cooling may be needed. A smaller PU resistor will be cheaper and use less space, but may not provide a solid, consistent output. Make sense??? Please 'Recommend Contributor' By the way, what is the application for these PUs?
Most home systems do offer both heating and cooling in one. Some of the older systems have separate heating and cooling. Heat pumps provide both heating and cooling. Other types of systems do not. However Heat Pumps can only efficiently heat a home if it's not excessively cold and therefore you usually need a supplementary heating system.
Depends on what type of worktop you are talking about. If your referring to a tool workshop, then neither, they are to expensive and will just get chipped and beat up. If this is not the case then go with quartz, as it is the most durable, and the most expensive there is. You will see this when you go to buy it that quartz is the most expensive.

A Honeywell heater is most typically used to heat a small space. They are portable units that provide a large amount of heat with a small amount of energy output.
appliances that provide heat energy
The most common way to provide heat in a home is by convection

The most expensive single object ever built might be the International Space State that cost an estimated 150 billion dollars or more to construct. The space station power grid is one of the most expensive power sources ever created.
you don't buy houses, but you buy rooms for your dogs/dog and the most expensive room is £/$100,000and the room is the space room
In space there is no heat. Only when a satellite enters the atmosphere is there heat because of the friction and it begins to burn. Spacecraft have tiles on them to shield from the heat. Most satellites burn up in the atmosphere once they are done or become "space junk."
Shade screens or heat insualtor window shades.
Some heat does escape into outerspace, but most is recycled elsewhere within the earth.
solid gold space rockets. Not only are they incredibly expensive, they are totally useless as they dissolve on exit, killing all on board.

Most coal is burnt to provide heat in a home's fireplace, or to heat a water boiler in a steam engine, or in a coal-fired power station.
