Trying to get my head around what I need to install UFH and four towel radiators and three small aluminium panel radiators. Been in touch with Wunda, asked about Wilo pumps and they said no longer supply, asked about a lower temp range blending valve and they said 35 is the min. So I started looking around at other suppliers. Came across Emmetti, and they do a mixed rail manifold M3V that has a hot side for rads and a cool side for UFH. Or is this just overcomplicating matters. Has anyone used their weather comp controls? They have a modulating blending valve connected to their weather comp, as I am feeding all the heating from a buffer tank, I presume I cannot weather comp the boiler, as it only gets a call for heat from the buffer stat, or the DHW stat in the main tank. My UFH is sitting in 55mm Cemfloor screed, sat on top of a concrete beam and block floor, with 300mm sprayed insulation on the underside, so it will be slow to respond. I was originally looking at Heatmiser Neo stats and multiple zones, but now thinking that due to the slow response, that the whole ground floor, circa 100m2 will eventually even out temp wise, and may be better controlled via weather comp and the modulating mixer valve. Has anyone any real life experience of this set up? It's a big learning curve for us, our project has gone from an estimate of six months to over 18 months in now, and we are keen to get the floor screeds in and heating going before winter. thanks Andy
