Air to Water Heating - Advice & Understanding

Inforapenny

Hi, recently moved into a new build (A2 rated, air to water heating system etc.). No underfloor heating.

Handover with foreman was fairly quick, a few manuals but nothing that gives a proper explanation on how the heating system works, manual more about the installation process

We have a thermostat upstairs and one downstairs with radiators in each room and some other heating thing in the hot press upstairs. Pics of all 3 below.

Is there a simple dummies guide to understanding it all anywhere? Google throws up a few things but nothing great.

Like, what do the two temperatures on the thermostat mean?

I think one of the icons on the thermostat indicates its set manually.

The radiators from what I can gather have never pumped out heat - not that we needed it yet as its the Summer months. But again good to know what do do we need to do come the Winer months.

Only two of us in the house and always seems to be hot water - whether that is good or bad I dont know.

Any advice or links to a dummies guide to it all would be great.

Thanks

Thermostats indicate set temperature and current room temperature.

You would not use those like you would use them with oil or gas heating. You would set the required temperature and leave it at that for the whole season. The reaction time is too slow to be thinking of putting them up at daytime and down at night etc.

Try and get your hands on installer or a service person to walk you through the lot. Take notes if you do this. You might not be much wiser though as these systems don't need much user input.

Thanks, I am going to try nab the foreman when I see him next, he is still on site.

Is the top temperature of the two the actual room or the set temperature?

Yes top is room temperature. I'd guess the higher one is upstairs.

Thank you.

Correct, the top thermostat picture is the upstairs in the house.

So without having the radiators on, the house is around 21 odd degrees.

Yes that's bout what you'd have this time of year from an A rated house.

Temperature is very subjective and you can become acclimatised to higher or lower temperatures.

I've worked in houses that people considered cool, while I was feeling too warm.

Is it best to get an air to water heat pump and hot water tank serviced during winter on a cold day so the engineer can get a good idea of how efficiently it's running? Or can it be serviced any time of year?
