    IVT Ecolane ASHP - any owners out there?

    ok so it is as i was thinking. The pipe stats tell the heat pump when to stop. Do you have 2 pipe stats or does your cylinder stat do the job for the DHW? Do you have any idea of how long the DHW takes to get up to temp on a normal day? Thanks Damian

    I think this is what the digital controller on mine does but i have no idea to do anything manually. confused is an understatement

    ok so your heat pump does have programs?

    @PeterW I'm trying as usual to get my head around all of this. I had imagined the heat pump itself had some kind of programs that pumped out water at a certain temperature instead of just heating the water until it reached a certain temperature and then stopping? So i assume that you just have the cylinder stat calling for water at 45 degrees and the room stats calling for water at 27 degrees until they are satisfied and then the heat pump turns off. Or do you need 2 pipe stats along with the cylinder stat? From your experience how long does the Heat pump take to get the Cylinder to temperature? I'm trying to get an idea of timings?

    no this is an over hang of plumber number 2. He suggested just using the floor itself as the buffer. I'm now not so sure that was a great idea. But kind of stuck at this point.

    Nice one. Its about as grey as my hair has gone in the last 5 years!

    UFH test pressure and duration.

    Since our system has been commissioned its now running at about 1.5-1.75 Bar I was thinking it was supposed to be higher but the plumber said it was fine.

    I'm getting senile the longer this build goes on. Hopefully you have a Massey 35, that would definitely cure some stress.

    If i had the budget i would get a sunamp and possibly a better ASHP but it is what it is right now and we need to get into the house (Baby #3 is coming in November) I may be able to get a second immersion and put that on a backup timing? Right now i'm not 100% confident that the Plumber and Spark know how to get the Basic W plan working with my Heat pump and deliver the 2 different temperature setup points without the digital controller.

    Its so hard to know whats the best thing to do. I have had 4 different plumbers working on the house and the most recent guy is kind of cleaning up after everyone else and trying to get it ship shape but i'm just a bit lost about whats the best way forward. The ASHP is currently running but no pipe stat means we just have to turn it on and off manually (its just running to make sure screed is ok before tiling) Current plumber has never worked with an ASHP that didn't have a digital controller so he seems a bit lost and its a tough spot to try and make decisions in .

    Sewage Smells!!

    What sort of Washing powder do you use? There can be a problem with some Biological washing powders and the affect they have on the bacteria in the treatment plant. May not be your issue but its something to be mindful of.

    Only 1 immersion on the tank at the minute. And it will be connected the an immersun type device so i'm not sure if that affects it being on a timer? Why were you advised not to use the water heater?

    IVT Ecolane ASHP - any owners out there?

    I dont mind the hot water having the priority as i'm looking at doing the following. UFH will be able to call for heat at any time once called by the room stats. Hot water will be heated a good portion of the time by the PV (I hope) heating time clock will turn on hot water at say 4pm (as we shower in the evening) and if the tank is not satisfied by the PV then the ASHP will start to pump at the higher temp to the tank. I'm still unsure of the details to be honest. I dont know how long it would take the heat pump to heat the Cylinder once its been switched on so may need to start the heating cycle earlier. I'm not sure if it will leave us with cold points in terms of heating if the Hot water is going to be on for 3-4 hours during the afternoon evening and the house cools down. I'm not sure if it would be possible to add some logic to the immersion that if the hot water isn't at temp by say 7pm then the immersion turns on? Or would i be better to just buy an in-line heater similar to @JSHarris and ensure that way that We always have DHW? Thanks Damian

    UFH test pressure and duration.

    I tested mine at 3 bar for about 3/4 weeks before screed pour. 1 manifold lost pressure as there was a very small drip from the pressure gauge connection, noticed that after about 2 days. Once that was tightened and refilled all was steady. When the screed was poured the pressure went up to about 4.5 bar and held there steady for another few weeks without issue.

    I have these connections available. Not photos but taken from the manual. The PSU control box looks like this . Then Inside the Heat Pump casing there are connections like this.
