32mm MDPE DZR Stopcock

Product Information

So I have a 24kW combi, with a 22mm supply pipe from the road (length 10 metres or so), until up close to the boiler. Pipes from the combi to points of use are mainly in 10mm PEX or 10mm copper. Flat Panel Radiators Low Surface Temperature Radiators Towel Radiators Designer Towel Rails Dual Fuel Towel Rails Electric Towel Rails Towel Rails Yes, the DHW outlet for a domestic combi boiler will only be 15mm , generally most just T off as you said. I suppose you still could go straight into a 22mm manifold then off to appliance in 10-15mm if you felt there was some benefit with that setup. These two books are the perfect starting place to help you get to grips with one of the most vitally important aspects of our society - our homes and living environment.

Posted By: ShevekJames, it's the water pipes I'm referring to (rather than the gas). I presume that in your second paragraph.It would seem even stranger to then carry on with 28 mm water pipe after the boiler if the inlet is only 15 mm. sorry , saw boiler , thought gas ! It is possible to have one thread that cover just about everything, there are a few on here, the M one and the W ones spring to mind

I haven't done calcs yet but Barney mentions the possibility of running 28 mm from the HWS generator to first floor and then on in 22 mm to the second floor (we're running two showers off the boiler): Water Heaters Instantaneous Water Heaters Unvented Water Heaters Vented Water Heaters Point Of Use Water Heaters Gas Fired Water Heaters Water Heater Accessories Ventilation Dehumidifiers Air Conditioning Air Purifiers Extractor Fans Water Treatment Central Heating Treatment Using a common body and only two sets of interchangeable components, Talbot Pushfit will connect to metric PE pipes and their imperial equivalents Fittings are tested and certified by major international approval institutions, including WRAS and KIWA re. water supply , not sure why you'd need 28mm but makes sense not to starve/reduce potential flow to the combi DHW cold feed as djh says , to other take offs . so using a larger bore up to boiler would priorities the DHW cold feed. On domestic jobs I general do it in 22mm up to combi boiler.Baths Freestanding Baths Shower Baths Standard Baths Bath Panels Bath Screens Bath Taps Bath Wastes Bath Accessories Bathroom Furniture Vanity Units Bathroom Mirrors Bathroom Cabinets & Storage Bathrooms Bathroom Taps Basin Taps Bath Taps Bidet Taps Tap Spares Basins Countertop Basins Wall Hung Basins Semi-Recessed Basins Pedestal Basins Semi-Pedestal Basins Basin Taps Basin Wastes Shower Trays Rectangular Shower Trays Square Shower Trays Quadrant Shower Trays Offset Shower Trays Wet Room Shower Trays Pentangle Shower Trays Shower Tray Accessories No, but why give yourself extra work by reducing before the stop-tap? Some utilities want the service MDPE to go in one length from stop tap to stop tap.
