Would it be any use if i posted installer settings from unit,just figured out how to get into them😀.

Installer left me no paperwork and told me nothing about system.

As such your installation doesn't comply with Part-L, sect 7 of the Building Regulations

The installer has to file notifications with your Local Planning Authority (LPA) to demonstrate compliance with the relevant Approved Documents of the Building Act.
At the very least a heat-pump installation falls within Part-L (heat) and Part-P (Electrics).

The LPA has Powers of Enforcement, both for non-filing and for deficiencies in compliance. So your installer won't want them involved.

You should go back to your installer with the above passages which I've quoted, and request that you receive

• a schematic showing the layout of your particular installation
• photographs with labels/descriptions for the controls and valves which are present
• a description of how to adjust the system for optimisation of its efficiency
• a description of the actions required to operate it (what to do if there's a leak, or the water is cold etc)

It isn't sufficient to simply hand over a pile of manuals for the individual parts which comprise your system.

Then tell us here what happened 🤨 

Im getting commissioning cert of them im told here in ireland thats whats needed. My plumber is to email it tonight. Id really appreciate some help just to see  if my installer settings are wrong.

On a separate matter, thanks for posting the above photo.

Would you like us to write anything about the levels of pipe insulation which are present on your system?

... or would you prefer to apply a level of common-sense greater than that exhibited by your professional installer, and make some observations yourself?

@transparent the copper pipes need lagging, that room is quite warm tbf but i take it thats what you mean.

I openly admit i dont know anything but im trying to learn as users here seemed very clued in on the system. Alot of old school plumbers dont know that much unfortunately.

The Technical Guidance documents of the Building Regulations for Ireland aren't much different to the Approved Documents, as they're called in UK.
What I've referred to in our Section 7 (above) is Sect 1.6.1 in Part-L of the Irish regulations.

Im sure they have all that, its unitherm who installed it so are a reputable company. The installer hadn't the best english but apparently he installs them around my area. Im hoping its just something simple wrong, so wondering if posting settings, somebody here might spot something simple as i really am trying to learn.

I have learned from just reading here my dhw settings are most likely off so will change that saturday. On nights with work this week so dont want go messing about half asleep.

Yup!
That room jolly well should be 'quite warm' with zero insulation on the pipes 😲 

For a heat-pump, the temperature differentials are very much smaller than those you'd find for a gas boiler.
Equally, underfloor heating uses lower temperature water with respect to the air temperature of the room.

Combine those two points and you'll quickly realise that the insulation levels for all pipes, valves, sensors and connectors is an extremely important part of the work.

Nothing can be commissioned until the flow & return temperatures are operating under normal conditions.
So zero insulation equates to a system which isn't yet set up.... let alone had its efficiency optimised.

Feck sake, yeah get whys its so hot now. so i could just lag all the copper pipes. Not sure about me doing stuff with valves and sensors though. He surley checked that flow and returns are within specs. How could installer be that shabby or is it just most people dont question things?
