    Hot water cylinder smart thermostat

    I was told it had not been tested! I'm not aware of any leaks, we have newly painted lath & Plaster ceilings so I'm sure if there were we'd know about it. Its been running for about 17 months, I might send Hep my test results :-)

    But doesn't barrier pipe solve that problem ?

    Hot water cylinder smart thermostat

    Hep Technical pointed out it had not been tested, so they could not guarantee it would work. But also pointed out as it had not been tested they could not say that it would not work. If the customer chooses to use it, it is at their own risk. What would be good if they could actually test it...

    Fair enough, to be honest I’d not considered lagging until the install was finished. Then the day we tested I was amazed at the temperature drop so got it lagged to death.

    Hot water cylinder smart thermostat

    There was a lot of debate about plastic, I recall the Hep2o spec advises it has not been tested on secondary. However, Hep2o technical advised it had been tested above the pressure required for secondary return so it should be okay, but as it just has not been tested they can’t warrant it will...

    I’ll check temp when I’m next there. Just to be clear, are you saying customer should have asked for spacers?

    Hot water cylinder smart thermostat

    You have a keen eye sir, unfortunately I can’t blame plumber for Grundfos sensor. Original Grundfos did not have sensor. It only lasted 6 months and failed. It was replaced under warranty, but they no longer made the basic model so sent one with sensor. I swapped it as it was straight forward...

    Thanks for link, I’ll get tape measure out on Friday when I am there, I think it’s okay, but I will confirm. I’ll also dig out MI while I’m there.

    Tundish is behind immersion heater, zoom in, you can just see bottom below immersion. I’ll measure runs. But otherwise is it okay?

    What does that mean, I asume 3 no. 15mm into 1 no. 22mm does not comply, am I correct, if so why not?

    Hot water cylinder smart thermostat

    I asked my plumber about servicing cylinder, he was hell yeah, you need to check this n that and that n this. Made sense having spoken to him. He said look at back of booklet got with cylinder, need to dig this out. I also took a photo

    Hot water cylinder smart thermostat

    I know the boiler was registered with BC, not sure about cylinder, is that a requirement? Shame about the register, that does sound like an oversight by our government. How often do you need to refresh your G3 to stay compliant?

    My G3 plumber is not gas safe.

    Hot water cylinder smart thermostat

    He’s defo G3, either going on refresher course shortly or just been on it. Albeit how can you check, is there a register like Gas safe? It’s in Hastings.

    Hot water cylinder smart thermostat

    I deserved that, it was a bit of a dump response. Boiler serviced yearly, I was referring to cylinder but did not make it clear. I did not get cylinder serviced, I’ll ask plumber about that tomorrow. Glad you commented about not changing thermostat. I’ll also mention this. I’ll see if I...

    Hot water cylinder smart thermostat

    It’s a new install, installed December 2017. What would need to be serviced? Bit more info, it has a 19kw heat exchanger, reheat time 45 minutes.

    Hot water cylinder smart thermostat

    Perfect, I had not even considered this. I was fixed on a smart thermostat. I have a 300L unvented cylinder, this serves 6 tenants, 2 showers. It has a secondary return and tank heated 24/7 by 20kw boiler. Until recently it’s never run out. But in the last 2 weeks we’ve run out of water twice...

    Hot water cylinder smart thermostat

    I’m looking for a Hot Water Cylinder Smart Thermostat. But I want to be able to monitor the tank temperature over time so I can see when the hot water is being drawn off and how quickly it recovers. So maybe recording the temperature every 5 minutes and saving this data. Does such a thing exist?
