heat exchanger

Check out the Helton range...... they have different sizes and you can select where you want the inlets/outlets; I ha\ve all 4 on the same end on mine.

You can also get different sizes.....some are large enough so that you can have a good supply of hot water ready and on tap. I just have a small exchanger for the shower and it's very good indeed.

thanks for the info,Roachie,have seen those, and look well made.Spending alot of time in vic high country still so not wanting to recycle water back through to shower,plus tank arrangement,how long for warm up on cold engine before use- a- billy- tee? cheers

I have a Twine in my GU. But they are all pretty good, I suppose it come down to personal preference and how you wish to install it. Some are all copper some are not, some have threaded ends some do not.

there are some units and installations here
