@s_calvert_heat @Damon_BPHR @johnwoodheating Booking a Skiing trip for me a Steve if you fancy being in the middle of us Damo

Amazing to see bakewell represented what strength @Damon_BPHR @johnwoodheating

@Damon_BPHR It's the best mate! Go for it

Anyone use the Milwaukee packout stuff? If so can you show me your set ups please.

@Damon_BPHR Smashing it mate! Loving the painted ply 👌

That’s a wrap for the week.. lagging, wiring, commissioning left to do

@_heatgeek B) 🤣🤣

@joypaincity @stefleck What are your thoughts via ASHP?

@HelygHeating @stefleck this is quite specialist. Have you ever done anything like this fleck?

Looking for some advice. I've been asked by my local distillery to look at ways at keeping their Mash at a temperature range from 25 - 35 degrees for fermentation. They have 1800litres stored in an insulated vat which are heated via these paddle heat exchangers (no kw rating) -

@howsieboyitsme They have asked me for a different option to heating them other than these paddles and trace heating at the bottom of the tanks. As the temperature they need to hold the tanks are very low an heat pump was my first thought. Not sure if it's been done as I'm looking into it.

@howsieboyitsme The tanks have been bought at auction and were heated via these paddles so there is no information on the running of them. It will be a new installation as the distillery has been buying in the Wash and will now be creating their own from these tanks.

@CustomRenewable @Openenergymon @ViessmannCS_UK @IMIHydronicUK @NewarkCylinders @_heatgeek 👏 let it flow 👌

They said it wasn’t possible it is now Viessmann 16kw 150a running open loop in a grade 2 listed house all off a single pump 🫣🤩😉

@Londonsgreen @ambienteufh Always like checking out new stuff 👌

@HelygHeating @ambienteufh They just brought out really thin repair couplings - and it’s just a compression fitting for the ufh to manifold … simple effective and decent price point imho. I can dm you the reps number … he does London but I’m sure he’d talk to y’all

@ambienteufh looking forward to using this on our next ufh project … game changer

@Damon_BPHR @suburbanpirate @HeatCalculation So the software doesn't take into account that even though you've input all your room temps are the same say 20dc it will look at default settings to parallel rooms and add them to the calcs throwing actual calcs out.

@HelygHeating @suburbanpirate @HeatCalculation Yes that’s right, it’s taking internal wall to parallel room temp so creating loses. You can see on the last appendix the internal wall loses.m also good to check through there at the end.

Hi @HeatCalculation. What's the best approach regarding internal walls? I always input them but usually design to 1 temp and seen a video saying not to input them if adjacent room is the same temp?

@Londonsgreen @ambienteufh Ah 😂

@HelygHeating @ambienteufh Actually the 16 flex might be ufh only … 🤣🤦‍♂️

@Londonsgreen @ambienteufh 🤔 can you use same fittings or are they specific fittings?

@HelygHeating @ambienteufh It’s Mlcp but not as I know it … super flexible . They have thinned out the aluminium and it’s just light and flexible like plastic but not. For me pulling Mlcp is a grind .. and anything to make it easier is a win.

@suburbanpirate @Damon_BPHR @HeatCalculation For my calculation I don't so no internal walls needed to be added to calcs? Does this mean that ceiling/first floor shouldn't be accounted for if it's 2 storey?

@HelygHeating @Damon_BPHR @HeatCalculation If you have 'adjacent loss' you need to balance that with 'adjacent gain' to prevent a net loss or gain.

@Damon_BPHR @suburbanpirate @HeatCalculation So the heat loss I did was 16kw with all rooms at 20dc, I input all internal walls this then made it think that adjacent rooms were 3 less and added to my heat loss. I've then removed all walls and it's brough it down to 12kw? Am I going wrong somewhere?

@HelygHeating @suburbanpirate @HeatCalculation All parrellel rooms are 18° so if you doing 21° throughout for eg you will lose 3° of heatloss between each internal wall. Your telling it what your loss is, no loss no wall needed.

@ewan_chamings @gmartinheating @HeatCalculation I've always included internal walls so never tried it before?

@HelygHeating @gmartinheating @HeatCalculation Did you see this behaviour before the update do you know? A few things have gone wonky since that happened.

@suburbanpirate @Damon_BPHR @HeatCalculation Yeah I'm going to check further tonight

@HelygHeating @Damon_BPHR @HeatCalculation Curious how that came about.

@gmartinheating @HeatCalculation Yeah that's exactly how I do it. I'll have to check again tonight with all figures to make sure I haven't messed up somewhere but 4kw difference is mad by just removing internal walls

@HelygHeating @HeatCalculation I design all rooms to same temp (20°c) and show internal walls, only because I have the ‘lowest parallel room temp’ set to 18°c. I’ve always left it to allow for setbacks and if homeowner limited some spaces (TRVs) 🤷‍♂️ Might be doing it wrong though?
