Nach 64 Jahren ist unser Haus jetzt #FossilFrei Ein wirklich tolles Gefühl.

Ich kann jetzt in Eigenleistung die alte Gas Heizung gefahrlos demontieren

Gute Nachrichten:
Laut den Monteuren von den Stadtwerken bauen sie aktuell nur noch Zähler aus.

Neue Gas Anschlüsse wurden schon länger nicht mehr hergestellt.

@mattferrell ANYONE can do this in their own home with a little extra leg work!

1. Fill your chest freezer with buckets of water.
2. Wait for the water to freeze. The heat pump in the freezer is pulling out the heat from the water and releasing it into your house.
3. Once the water is fully frozen, it won't be releasing any more heat, so haul the buckets outside and dump them.
4. Return to step #1 and repeat until your house is at the desired temperature.

Two plastic buckets sit on top of an older-model chest freezer in an unfinished basement with cinder block walls.

@TimWardCam And I only boost from grid (eg for a winter-time legionella cycle) when demand is low and, if possible, grid carbon intensity is relatively low.

This scheme has been adjusted since the #heatPump went in, since the heat pump *is* the lowest-carbon way to use electricity (including from our PV) to make DHW. But it is far from agile enough, and the timing is usually wrong for that marriage.

Latest follow-up podcast is out! YouTube: https://youtu.be/Tq3IS1J3Lyo Audio version: https://share.transistor.fm/s/8a046aa2 Sean and I talk about using ice to generate heat. Yes, it’s actually a thing, but does it make sense for the future of heating?

Hier #Wärmepumpe #HeatPump Bubble, für wie wichtig haltet ihr den Warmwasser-Speicher als Teil des Gesamtsystems? Wir haben hier ein Angebot mit einem relativ günstigen Speicher (vermutlich mady in China) statt einem Gerät vom WP-Hersteller selbst.

Anyone I know in UK who uses a Air Sourced heat pump? How much electricity does it consume over winter? #HeatPump #Solar #PV

Does anyone have recommends for book or website I can use to educate myself on options for upgrading a postwar bungalow from a gas furnace + AC to heat pump(s)? The book I have is OK for basic principles but I’m looking for more what units are available, cost, installation pitfalls.

I have asthma which is aggravated by the current system blowing dust around summer + winter. Primary motivation is comfort, better energy efficiency would be bonus points. #HVAC #HeatPump #minisplit #renovation

A paperback book on the subject of heat pumps. Author S. Ziegler.

Are ice-source heat pumps a refreshing idea?

Last fall, I installed a #Turbro #MiniSplit #HeatPump from #HomeDepot in the back yard shed we call the "MicroBarn". Read the Alt Txt - that's where the story is. But this is about #Histeresis and failure to exploit it.

Screenshot from NetAtmo website wherein the green line graphs the outdoor temp, the blue line the temp in my basement office #HamShack, and the pink line is the back yard (mostly) insulated shed (where I do man-cave things).

In this example, the Mini Split is in Heat mode. Note that the temp rises gradually when it's heating with the outside around 20F. Then it meets the set point, stops, and the temp plummets. It's on for an hour or more for each of these cycles.

Another screenshot from NetAtmo website wherein the green line graphs the outdoor temp, the blue line the temp in my basement office #HamShack, and the pink line is the back yard (mostly) insulated shed (where I do man-cave things).

In this example, the Mini Split is in Auto mode. But UNLIKE the #Nest thermostat in the house, this Auto mode does not have two set points, for Max desired temp and Min desired temp. It has a single set point, which is really stupid. But with no other choice, I pick a number.

It's in Auto mode because Spring is coming, and if it's sunny and warm out, the temp can quickly rise in the shed. Then the sun goes down and the temp plummets. So within the same day, there will be a need for cooling and for heat. You know, the sort of shit that thermostats that control both heating and cooling were invented for.

But note that with outside temps in the 30s F, the Mini Split is able to satisfy the heat need pretty quickly. And then it rises above the set point, and the cooling cycle kicks in.

So each of these heat-then-cool cycles lasts 15-20 minutes.

These stupid fuckers have this thing running both directions multiple times in the same hour because they could not be bothered to give me two set points to define a reasonable range of temperatures. Hell, if I could give it a range of 8 degrees, it would use only one mode at any time, and cycle about hourly.

This is not how to do efficiency, people.

How can an ice source heat pump raise temperatures through freezing?

Well obviously I found ways to avoid getting on with my #research (though I did take a good first step), and instead have made a small change which should significantly improve #solar #selfConsumption by the #heatPump via the #battery...
