120 Navitron tubes heating a Navitron 126 litre Vented Cylinder and going through a 170k BTU Navitron Heat Exchanger to heat the pool
My top tips
1. When you rely on someone else to put in a check valve double check it is round the right way. Then check again
2. When testing the pipes by grabbing them check the controller isnt telling you they are at 160Oc
3. Have some blankets or old curtains ready to cover the tubes for that bit when steam is pouring everywhere and you are trying to read the forums as fast as possible to figure out a check valve is round the wrong way!
Next job
1. More insulation
2. Waterproof the insulation on the roof somehow looking for a good idea!
3. Finish off the 1-wire network to monitor it
4. Take out the autobleed and put in a manual bleed after a gate valve
Apart from that it seems to be fine
All done with help from this forum
Thanks

No that is the central heating pipe - all the solar ones have armiflex on them
Quite a lot outside too - which I need a way to waterproof.....

Waterproof the insulation on the roof somehow looking for a good idea! How's about using plastic down-pipe? Might have to split it to get it over the insulation and then seal the split with silicon. Depends on getting the right diameter to fit the insulation to be covered and how unsightly it would appear. But at about £2/metre not too expensive. Got a couple of short lengths on my roof. Just a suggestion. Rob. |

Hey rob, that a good idea to use plastic pipe. Ivan told me that apparently the birds seem to take a likling to the armaflex insulation outside so he used insulation tape on mine.

Martin,
I meant to include using strong cable tie-wraps (matching colour of course) to help keep the joint together on the length of the pipe. All that expansion and contraction might break a simple silicon seal.

I wrapped the foil type insulation around the Armaflex and held it in place with tie wraps.
