Thanks John. Will call the local water company back, we've just into this property and i'm not too familiar with the pressurised system setup so was trying to understand that also. Maybe daft question but should the pressure gauge close to the vessel and gauge on the boiler be the same...

Hi all, I've just had a water meter installed and now the water flow in the house is very slow, seems to be affecting both cold and hot. The heating system is pressurised and i have the Zilmet Ultra-pro vessel. I'm wondering if there was some pre-cautionary measure that i should've taken...

Hello again! I've attached picture of the Siemens wiring of the programmer. 2 things: 1) Only the CH & HW 'ON' is connected. As i've read around i think that is fine, you only need to call the boiler ON anyway and not off. 2) Noticed there is a feed from the live out, trying to trace...

Thanks!! Will do that.

Yes, as i took it off the wall the red wire fell out but it was in COM yes. It's the live to the box

Yes, i think the main functions give the same, i did like the idea of zoning with linked TRV's but also don't like the idea of the boiler firing up for the sake of trying to get one room up to a desired temperature. Nest has the learning but like you i've heard that can be random and most...

That's great and makes the install reasonably easy, thanks a lot for providing the detail. What's your opinion of the Hive vs other smart thermostats around, some have a few unique points but generally they all function much the same? Thanks.

Hi Stem. Many thanks for the response. Checking further. The Salus receiver is installed next to the hot water cylinder and also there is a programmer next to it with Heating and Water set to 'always on'. I wasn't sure how that was used as the boiler only fires up via me setting schedules...

Hello all. My current setup is Worcester Greenstar 24i Boiler and hot water cylinder. The boiler programmer/thermostat is the wireless Salus RT500F. I'm looking to replace the Salus with a Hive dual channel and wanted to understand how the wires are connected back to the boiler. I've...
