Has an EnerPHit been constructed in the UK that has retained timber joists embedded in walls?

[David Lam @sparkoslamos]

Does anyone have any expience of single horizontal bar towel rads in a Passivhaus?
Are they effective in drying towels?
Are they even necessary?
Thanks!

[David Lam @sparkoslamos]

Does anyone know any decent windows for a Passivhaus that have been tested with an actuator to EN12101, aka smoke vents?

[David Lam @sparkoslamos]

Proudly watching my very talented wife @TheGabbyWong in Macbeth @The_Globe today. She's my constant source of inspiration!

Has anybody tested a multi-resi building on an apartment by apartment basis by making each apartment airtight to Passivhaus standard? @PHAccelerator @PassivhausTrust @phplusmag Thanks!

Need to quickly cool down your toddler's dinner? No problem, just make sure your heat pump is running when you've finished cooking.

@mwt2008 @Zapaman @bbcquestiontime I'm surprised we're that high! Above Germany?!

[David Lam @sparkoslamos]

How much do people spend on an annual service of their heat pump? Would they spend the same amount on a boiler?

[David Lam @sparkoslamos]

@Mike_Sammon @Zapaman @_heatgeek For my limited brain, can you tell me why the Sunamp would have a lower SCOP please. Or am I misunderstanding?

[David Lam @sparkoslamos]

@JeremyClimas If the former this has been on my bucket list https://t.co/gp6BiKvRll

[David Lam @sparkoslamos]

@JeremyClimas You mean theory or practice?

[David Lam @sparkoslamos]

@MarkSiddallRIBA @JeremyClimas @swebster56 @Damon_BPHR No, the house is always warm.

Historic England is seeking to better understand the use and performance of insulating lime plasters and renders on traditional stone and brick buildings. The aim of this study is to undertake a review of the proprietary insulated lime products currently available in the UK

@AyseTashkiran Icebreaker are pricey but do the trick!

@heatpolicyrich 3 bed mid terrace Victorian house. With a heat pump. Constantly at 20 degs.

[David Lam @sparkoslamos]

-2 degs outside. Less than 40 Deg flow temp. Inside is really toasty. Mostly radiators. Tiny UFH area.

@Greengaugenergy Ha! My morning brain actually went to that website to find someone called Drilly.

[David Lam @sparkoslamos]

Does anybody have any data for how deep timber joists are generally embedded in masonry? Is it more likely to be a half brick's or full brick's worth?

[David Lam @sparkoslamos]

@JeremyClimas Are you thinking of insulating the house after or doing any airtightness measures?
