What does this +5 do to water law, Samsung ashp

[Andehh]

, I have increased my Samsung water law by +5 degrees to see what it does.... But it's difficult to tell?

 

Can anyone advise in layman's terms please?

 

Thanks

If your Water Law (WC) with no adjustment was, for example, set as:-

Outside 15>>>>>>>>>>>>>>>>> -2 deg C

Flow      35>>>>>>>>>>>>>>>>>50 deg C

 

your adjustment of +5 to the flow temp takes effect across the whole range, so the Water Law becomes:-

 

Outside 15>>>>>>>>>>>>>>>>> -2 deg C

Flow      40>>>>>>>>>>>>>>>>>55 deg C

 

so either you should be feeling a lot warmer, or your room stat cuts the heating sooner, or both.

Thanks very much!

 

mine looks to be:

 

Outdoor temp got water law:

15 degrees ........3.0

 

Water out temp for WL1 Heat (WL1 floor)

36 degrees..... 43degrees high target

 

Water temp out for WL2 Heat (wl2-fcu)

36 degs....... 43 degrees

 

However even boosting it by the 5 degrees as you suggested, after 3.5 hours of running my UFH temp is still only 29.2 degrees it is - 3.5 degrees outside.

 

 

We have a very well Insulated property, but a few of the rooms have a small floor area but have high ceilings/Mezzanines. This means they do struggle to get warm when it gets very cold.... Just too little surface area.

 

 

With the octopuses cosy tariffs I'm less worried at efficiency, vs hammering the electricity when it's only 11p during the cheap rates.

 

 

Is there a reason I'm not seeing the 29degree water outlet temp getting to something warmer to really force the heat into these rooms? Was hoping the +5degrees would do this!

For what it's worth we are fairly lightly zoned, basically children's bedrooms vs master room and bathrooms vs living areas....again to try and force as much heat as possible into the small but tall children bedrooms. Morning and afternoon cosy everything is on until thermostats hit 22 degree limits (rare in this cold level temps), but the 10 to 12 is only children's bedroom is give them the extra helping hand.
