How flexible is ISOFLOW pre-insulated pipe?
Very. Take our super insulated 32mm double in a 160mm duct - it has a 500mm bend radius that's easy to achieve with one pair of hands. Designed specifically to reduce bend radius meaning the pipe is simply curved out of the ground - no underground elbows required. Refer to tech specs for the bend radius for your specific product.
Does the system comply?
Yes. ISOFLOW pipe has been designed in accordance with BSEN 15632 1,3, cold and DHW potable pipe is also WRAS approved
What's the lead time?
Most sizes 25mm to 63mm are available for next day delivery if ordered before midday. Above 63mm approx. one week, please call to check the specific product you require.
How good is the heat retention?
Excellent. Take our 32mm double in a 160mm duct - only 7.7watts per metre heat loss at typical ASHP flow/return temps of 45C/35C.
Do the fittings require special tools?
No. Our clamp type fittings use a stainless steel bolt - a spanner or socket set is all you need.
