Posted By: tonyDefrosting food from freezer indoorsNot sure I can agree with this one ... though it depends when it was frozen. All the heat taken out of the food to freeze it was put into the house by the freezer anyway.
Posted By: tonyCold water cisterns - the loo one if not the CW tank - importing cold water which gets warmed up by the house interior before being flushed away warmThis is a fairly tiny amount - if you have a 6l per flush loo and the water gets heated from 10C to 20C, you're only losing 0.07kWh. The water probably never gets up to 20C anyway unless you rarely flush the loo.
Posted By: tonyDrying clothes indoors - latent heat of evaporation is sucked out of the house interiorDoesn't it just condense on everyone's trickle-vented windows? ;)
Posted By: Paul in MontrealTrue, if frozen by own freezer, but if bought frozen and put into the freezer then it remains a heat-loss when unfrozen in the house.Defrosting food from freezer indoorsNot sure I can agree with this one ... though it depends when it was frozen.

Posted By: Paul in MontrealWater in at 5C, so 0.1kWh if it reaches 20C, which it will sometimes e.g.overnight. 0.1kWh is 13% of 1hr's output of a carthorse or a 1ft wide x 12ft diam overshot waterwheel - not tiny in fuel-less future terms! Multipled by many loo visits with partial warming/cooling. it's regarded as an issue in Passivhaus.Cold water cisterns - the loo one if not the CW tank - importing cold water which gets warmed up by the house interior before being flushed away warmThis is a fairly tiny amount - if you have a 6l per flush loo and the water gets heated from 10C to 20C, you're only losing 0.07kWh.

Of course, an easy solution is an internally insulated water tank on the loo - many people have these to prevent condensation anyway. Of course, in the summer, the flushing of the loo provides a tiny bit of welcome cooling too ;) All that said, the energy flushed down the loo is equal to a few cups of tea. Maybe the trick is to let the energy from the tea, after it has "flowed through" into the loo sit there for a bit to make up for heating the flushing water.
Posted By: SteamyTea"If its yellow, let it mellow"The other oco solution (assuming you're not going to use the urea as a fertilizer) is to combine tasks when you take a shower, so long as you have a drainwater heat recovery system. Then any heat you're otherwise flushing down the loo is also captured with the shower drain water!!
I used to live the tropics and no way can I put up with not flushing, an eco step too far for me

Posted By: Paul in MontrealHaving a month ago taken to envigorating cold showers (hot shower then cold hot cold hot cold hot) I can assure everyone that mains cold has got a great deal colder during that time, and it was never 10C.Posted By: fostertomWater in at 5C, so 0.1kWh if it reaches 20C, which it will sometimes e.g.overnight.Why would the incoming water be at 5C in the UK where the ground temperature is 10C?
Posted By: fostertomWhat temp is ground water typically? You'd assume the same as that alleged stable 10-12C dry soil temp at 2-3m down - but spring water's usually colder than that, perhaps preferring the 4C anomally temp (maximum density) of water, which Schauberger said is the most energetic and lively state typical of vortexing mountain streams.
Posted By: fostertomNot long - just long enough for the elect shower to run cold plus a few secs then hot then cold
