Thanks Stem, some great advice there. Yes, I did wonder if the pump was running out of water but I'll be honest, I don't know how it works. I assumed the pump spinning would actually 'pull' the water from the cylinder, hence not relying on the gravity feed, but going by your description, it...

I had a quick look today when I was there. Posted below are a couple of pics. It looks like there is a feed from the top of the water tank into the pump and then the output from the pump goes into the copper pipes which feed the hot taps around the flat. I couldn't actually find the stop cock...

Oh really, no surprise. Next time I'm there, I will take some pics. I did wonder if it was a water flow problem. I have no idea how these things work. Would the pump pull from the tank or just pump what water is already sat at the inlet that's been fed by gravity?

I'm sure it's out of warranty now and I'm not even sure who fitted it now, it's something my brother organised.

Hoping somebody can help. In my rental flat, the hot water is fed from an immersion heater but the flow rate was abysmal. I had a plumber install a Salamander CT55XTRA pump several years ago to provide more pressure. It's never been great and has worked intermittently. At times, when it did...

Thanks, I'll take a look next time I'm there.

Thanks both. Yes, I assumed it was due to people drying towels even though I've told them not to. There was another heater in the same property which also wasn't working. I managed to find the mechanical trip on that one (watched a YouTube video). The one mentioned in my post might be a bit...

Hello, hoping somebody can help. I have a unidare WMS724N storage heater that's not working. An electrician I know had a quick look and couldn't see anything wrong with the supply. After a bit of reading, I've seen that it's common for thermal fuses to blow/trip. Does anyone know what the...

I've had a look at the Wiser kit and it looks pretty good. A couple of observations. They appear to be expensive compared to Salus (I'll need to buy 5 thermostats) and they don't have half of the accessories that Salus does. I liked the fact that you can add the window sensor to the Salus...

I will add it to my 'research' list

Yes, I have a Vaillant Ecotec Plus 837. Doesn't look like it supports opentherm, but will do simple on/off boiler switching. I have room stats/zones downstairs to control the UFH temp, I just need something to tell it to switch the boiler on when the UFH room stat calls for heat. I just assumed...

I stumbled across a Nest thermostat video on YouTube. I'd always steered away from these for some reason as I assumed they wouldn't work for me needing to control downstairs UFH and upstairs radiators but I think they do as they have a hot water connection. It looks like they also support...

Thanks everyone, one thing's for sure. This place is an absolute disaster. So, guess I'm back to having to rip out the floor at some point, insulating with PIR board and starting again. If only people could do things properly first time.

Bit of an update today. I lifted a couple of the floorboards under my stairs. From what I can tell from the visibility I had, there is no foam/PIR boards under the floor between the 100mm joists. I got a couple of photos from above and it looks like the hot feed from the boiler to the UFH...

Thanks very much. Sorry, I haven't responded, I'm still stuck t work . It seems I have lots to read/learn. Let me digest and I'll no doubt be back with some questions.

Thanks, as you say, you've certainly brought some new ideas to the table. Albeit, rather expensive from a quick google..... I don't have a DHW cylinder at present. The house is a 3-bed detached, with 2 bathrooms, not massive. I currently have Heatmiser stats using RF without issue. I have...

Oh really, that's a shame. They seem to have a device to suit most scenarios..... Any other feedback on Salus?

Hi all, hope you can help. Central heating systems aren't my strong point and replacing anything at the moment could be risky as the Mrs will not be happy if I break something. I'm trying to limit energy usage for the random days we work from home. Heating the single office room sounds sensible...

Yep, as soon as I get a chance, I will investigate.

I understand the issues in the loft. I know it's not very popular due to condensation and rotting timber, but I would have thought under the house would be okay, especially if air bricks were still aren't blocked and ventilation isn't an issue.
