Fast warm up ideas: 5,500 watt, 19,000 BTU per hour coolant heater

The last post

My old coolant heaters were just screwed together steel water pipe with a hot water heater element.
The 5,500 watt heater element needs a 2 inch pipe and reducer bushing upon reducer bushing to bring 2 inch down to a useable 3/4 to 1 inch NPT, which makes the pipe section really bulky and heavy.

I am trading out the heavy iron parts for a length of 2''ID .065'' wall 316 steam pipe and 1.5 inch 304 stainless steel fittings.
I found that 2 inch pipe is almost too small for the doubled over heating element. The heating element also touches the sides of the enclosure with 1.5 inch pipe a lot. The steam pipe is part of a 15 foot section, still needs to be cut.

The ports on this will be 1''NPT and 3/4''NPT, which is perfect for the 5/8''ID heater hose inlet and 3/4''ID heater hose outlet.

This coolant warmer will be powered externally by high voltage 240 volt AC.

To install 240v power at your drive way can cost $50 to $100 in materials depending how close a main or sub panel is to your drive way if you can do it your self.
I already have drive way 240v power for powering my welder and plasma cutter.
To get 240v power installed at the drive way I have herd of it costing as much as $500 for an electrician to run a wire and install a plug if that is all that you need. It can cost up to a few thousand if all of your electrical is out of date and has to be redone.
