I have fitted the Trianco aztec boilers and my personal opinion is that they are a good bit of kit virtually 100% efficient, the bigger units (multi-element) are fully modulating and maintenance free! when was the last time you bought a kettle because it had packed up?
You obviously need to...
If you used hep20 pipe and fittings i have been reliably informed by an ex technician from hepworth the pipe and fittings will withstand 70 bar!!! thats the typical burst pressure they achieved at the factory.

I am going to relocate my oil tank and run a new oil line, could someone please advise on the laying of the oil line with regard to depth of trench and what sort of protection is required i.e. trunking,i will be using 10mm plastic coated copper pipe.
Thanks in advance.
