Hi: Here in the U.K. we can buy push-fit plastic fittings which go onto copper tubing.
A few years ago I extended my heating system using them. Plastic pipe is also available. Some years ago I tested a piece of copper fixed to plastic with a coupling in the Physics labs at our local university, with a professor friend of mine. We tested up to 95 degrees C and 3 atmospheres of pressure - impressively, it held!

I've got guys in the house replacing my furnace. The new contraption looks wild. There are pipes going everywhere. It is an indirect hot water tank and hot water heat. The water that is used to heat the house, flows around an inner tank that is used for the potable hot water. So, the furnace heats both the house and the potable hot water. There is an automatic over-ride switch that will shut the house heat pump down if potable hot water is needed. I asked the guys about all the soldering, but they don't solder much. They use special fittings that have an O ring inside the fitting, then a power tool that rolls around the fitting and crimps it onto the pipe. Pretty slick. They say it is a huge time saver but the tool that does the crimping is pretty expensive and the fittings are more expensive than your standard fittings as well. -- Blue skies.
