here is a thread that discusses pool table heaters. on some snooker tables they heat the table to keep humidity low and the table a bit warm as this affects the speed of the cloth.
I understand that the high end billiards tables are heated so that they will play the same no matter what the temperature is and the humidity. So why arent the high end pool tables heated, or has anyone actually seen a heated pool table...

In it, someone commented that the heater takes power. I just wanted to also make the point that if you are heating the room, any heat created in the room is not lost heat, because it all contributes heat energy to the room anyway.
i often see this mistake being made when comparisons are made for different lighting sources. Sure an LED saves power, but if you are running an electric heater the efficiency in terms of BTU's and KW hours is the same weather it is a light bulb producing the heat or a baseboard heater, for example. If this little obvious factor is not part of the energy savings analysis ( such as often the case when it is written on a package of LED bulbs) it creates a false sense of savings.
I pulled a lot of old fluorescent fixtures out of my house and replaced them with the more efficient LED bulbs. sure it saves power, but I also burn more gas making up those extra BTU's. ( in winter)
In summer it is a savings and the inefficient florescent may actually work against any money spend on powering AC. Then there is savings.
having a fridge in a warm kitchen area is similar, it produces a lot of heat to make the cold and in winter it's cold out anyway so we are spending to make it cold, creating heat doing it and that really paints a picture of inefficiency if you think about it.. we could simply vent cold air in to the fridge or put the fridge on the back porch so it isn't working so hard. Usually this is never done because of complexity of installation.
earlier in my own renos I put my fridge in a sort of a cubby, I was thinking I could vent it to the outside during winter, It would save a bit of energy. likewise the heat from the coils at the back could be made to exit in the summer so it isn't battling any AC. I do not know why the makers of fridges cant' see that its obviosly a pretty ineffficient system, but every one uses the same basic idea. They never seem to take the obvious into account to make fridge's more efficient.
