I know conversation moved on but you could use a beer pump to deliver beer longer distances without overcarbonating beer.

Beer pump meaning beer engine?
He's talking about an electric pump.  Some brewpubs use them instead of CO2 to push beer when the serving tank is a good distance from the tap.

Ah, hrm. If I were doing a real bar, yeah, why not - but I'd be worried about the pump getting sticky because I'd only be pulling a pint or two per day.

Well, you'll just have to drink more.

Not everyone has as capable of a liver as you.  ;)
Is that a counter-pressure bottle filler in your pocket, or are you just happy to see me?

I do not think it will get sticky.
Your beer line inside does not get sticky.
May be better solution for you is to have bigger ID beer lines.

I recall seeing this a while back. This is a DIY system that doesn't take a rocket scientist to figure out.

To ensure perfect aim, shoot first and call whatever you hit the target.This works in brewing, too.

I've done what the OP is asking about.  I have a two-gallon bucket of propylene glycol in a small chest freezer along with frozen food.  A small pond pump is submerged in the glycol and supply and return tubes run out of the freezer and into the kegerator, where they are joined by 4 beer lines in a trunk line purchased from Micromatic.  The trunk line travels about 20 feet and through a wall to the taps in my basement bar.  The beer tubing in the trunk line is barrier tubing with very low resistance.

You cannot have the glycol reservoir in your kegerator.  The heat generated by the pump will always maintain the glycol temperature above the surrounding freezer temperature--the temperature of your beer.  This system has been in service for almost a year and I'm happy with it.  The temperature in my glycol bucket is around 32F (the freezer is at -10F)

@rob what was the parts cost like on that? Sounds pretty reasonable... And way cheaper than the 800 eur I was going to spend on the machine.

The expenses related just to the glycol system were
additional freezer (serves double duty with frozen food),   $200
trunk line, 20-ft                                                            $350
pond pump for the gycol.                                               $ 30
propylene glycol, 2 gal                                                  $ 20
wood collar on freezer                                                   $ 40

So that's $540, but since we keep a lot of frozen food in the freezer, that $200 shouldn't really count.

With my small glycol reservoir, the glycol doesn't have much residence time, so I get a temperature much higher than the freezer temperature.  If I wanted a lower glycol temperature, I would just use a bigger bucket and more glycol.
