@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.

@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.

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
