Insulating pipework in hotpress - compression fittings

tipperary

All

Just wondering how people go about fitting pipe insulation over compression fittings? The insulation sized for the pipes obviously will not fit over the fittings, while if I get larger insulation to fit over the fittings, this will be too big for the pipe. How is this details best solved?

Don't insulate them:D.
On sites compression fitting would not normally be insulated by the lagers because there would not normally be too many of them due to welded, soldered fittings being used and having the same diameter as the pipe,

On larger flanged and compression fittings, insulating bags would be used to wrap them but I have never seen them in the domestic market.

You could increase the size of the insulation to match the fitting and tape with insulating tape.
If it's only a couple of fittings you would not see the savings made by wrapping them.

You can use the foil wrapping tape - Thermawrap.

If you want to insulate pipes use Class O Armaflex 13mm wall or equivalent (must be Class O) to achieve good thermal resistance. Anything else is fodder.

Save yourself money. dont insulate your hot press. if your watertank is directly above it then it will stop it freezing in winter. Just pull the fibre glass up around the side of the tank. Not underneath the tank

If the tank is not above it then pull the insulation over the top of the hotpress in the attic and let the heat escape back out onto the landon heating it.

When children play Bob the builder we hear rubbish like above ....

Here is a brochure showing correct insulation work for a particular insulant/brand :

Different situations demand different solutions. Contact a professional. Ask for the EN standard he follows when insulating pipe works. Get this in writing, signed and sealed. No answer to that question: Bob the builder want's to fidle some money out of your pocket.
The same goes for a DIY aproach: ask for the installation manual of the particular material you plan to purchase. Check if this installation manual mentions the relevant EN standard.

Heinbloed...I see that you are still at it

For once in your life,could you please stop putting down everyone here.
You really do have a rather pathetic way of posting on the forum.

Why cant you post in a more polite manner and be a bit more civil to others?????

Thank you. You have made it easy for me. Hope you enjoyed your stay but now you have to leave.


Unless your appeal is successful(and i very much doubt it) this is now permanant.

Nice 1 joey
Their is absolutely no need for rudeness,
Getting back to the original question about insulation.
Just use a larger size diameter of insulation, put it over the fitting and use silver tape to seal
Job done, DIY style.

Would I be right in saying that Hoenblood is not aware of the law of diminishing returns?

Btw, I now realise that it was quite the insult I received in another thread when I was accused of being a Honblood rereg!

the advise to not insulate your hotpress is incorrect and against the building regs part L page 22 1.4.4.4 the pipes connected to hot water storage vessels including the vent pipe and primary flow and return to the heat exchanger where fitted should be insulated as outlined in paragraph 1.4.4.3 for at least one metre from there point of connection. so while i donot want to defend hein a lot of his information was correct

Thanks all for the bits of advice. For the hot water circuit in particular I am keen to have it as well insulated as is feasible, as I end up supplementing the solar panels with the oil boiler most days, and want to minimise the heat lost. I will go with the larger size insulation for the areas where the fittings are, with the 'correct' sized insulation elsewhere. While I am not as worried about the central heating circuits, I do plan to insulate these within the hotpress also while I'm at it at all.

I hope to use the armaflex self seal stuff, and am trying to source this at the moment. If anyone knows of a place to get this for good value, either in Cork or online, I would welcome any suggestions.

Again, thanks to all for your advice. While I am not necessarily following all the advice given, I nevertheless appreciate people taking the time to give their input.

His information is always correct. His attitude is condescending, disrespective and has no place in normal conversation.

Your right though. All pipes should be insulated but sometimes it makes sense when you dont insulate certain ones... For example the "Hot" press.

But i agree with you.

Hi tipp
Quick question
Have u a solid fuel back boiler??

yes, I do indeed have a solid fuel back boiler. Bit puzzled as to the relevance of this though

Hi Tipperary
You said you were supplementing your solar most days with oil..
You might have thermosiphining going on.
Check if the back of the solid fuel boiler is getting warm as this could be draining the energy from your water tank

Ah OK, thanks. Just checked the pipes at the back of the stove and they are both cool, so should be OK. Thanks all the same though.
