Do you manufacture a lead to Hep2O adaptor?No. Our suggestion would be to use a leadlock fitting (readily available in builders merchants – use our Stockist Locator to find your local branch), which is a compression fitting to connect lead pipe to copper pipe.
Yes, unlike copper, no matter how soft (acidic) the water is it will not corrode the HepO pipe.
No. To adapt from 1″ copper pipe to 28mm Hep O they need to use a 1″ to 28mm copper adaptor.
No, this isn’t possible.
Most boilers have a control stat that limits the temperature to 82deg c and the limit stat would operate at 95-100deg c.
If the limit stat is above this level (from manufacturers' data) it probably means that the boiler has a high thermal mass and will continue to transfer heat from the heat exchanger to the water even after the boiler has ceased firing (thermal inertia).
This is exactly as it would be for copper and is dependent on the thermal conductivity in w/(mk) of the insulating material.
For example, externally for a 15mm pipe, this would be 27mm for a material with a conductivity of 0.035 or 100mm with thermal conductivity of 0.07, so refer to the insulation supplier.
No. Due to the uncontrolled temperature, the cooker has the potential to reach excessive temperatures. Copper must be used.
Not to anything like the same degree.
Yes, Hep O should be insulated in exactly the same way and to the same thickness as copper.
Hep O will fit directly into most TRVs and pipe support should be used as with compression fittings. You could also convert Hep O to something else (copper, etc.) via compression.
Yes, simply use the HD3A/22 adaptor.
An HD1/15 – 15mm straight connector will fit onto the old imperial pipe so you can convert to 15mm HepO.
No, regulations state soft copper must be used for this purpose.
No, this has to be copper.
