First electric car, a driveway, and a socket in the garage. Quotes for a wall charger are a meaningful amount of money and the car came with a lead that plugs into an ordinary socket. Everybody I ask says get the proper…
The outdoor unit of our air source heat pump is noticeably audible from the garden and, on a cold still night, from the nearest bedroom. Neighbours have not said anything yet but the gardens are narrow. The installer…
Our heat pump is quoted at a particular kilowatt output, and that is the number everyone repeats the installer, the paperwork, the sticker on the unit. On the coldest days this winter the house did not quite hold…
Our air source heat pump is a reversible model, so in principle it can run the cycle backwards and cool the house. When I asked about it I got a vague answer about it depending on the emitters and something about…
Gas combi from 2011, about 14,000 kWh of gas a year, cavity walls filled and loft at roughly 270 mm, but the ground floor is suspended timber and noticeably draughty. Two quotes in, both in the mid teens of thousands…
Suppose I live somewhere cold enough that I am heating my home at essentially all times, and consider a room with no windows. An inefficient bulb turns most of its electricity into heat rather than light. But that heat…
Southwestern Ontario, about 1,800 sq ft, gas furnace from 2009 plus a fifteen year old AC that is clearly on borrowed time. Since I need to replace the AC anyway, a cold climate heat pump ought to be the obvious swap,…
UK, 8 kW air source pump about a year in, no battery, small hot water cylinder, and both of us work from home so the heating runs through the day rather than in bursts. We are on a standard flat rate now. Everyone tells…
Electric resistance tank, twelve years old, sitting in an attached garage that hovers around 5 10°C for most of the winter. Family of four, showers are basically the whole load. The heat pump models cost meaningfully…
Roughly 11,000 kWh a year, south facing roof with no meaningful shading, utility rate around $0.19/kWh and net billing that credits exports below retail. Every payback calculator I can find still assumes the 30%…
US, system was switched on in November 2025 and I filed the 2025 return this spring. I expected the credit to arrive as a refund and instead the software applied a chunk of it and carried the rest to next year, and I…
I don't have the cash for an outright system and the financing quotes I've had are unappealing. Two companies have pitched me a lease and a PPA respectively, no money down, monthly payment below my current bill. My…
Flat with no outdoor drying space and a vented dryer that turns the kitchen into a sauna. Four loads a week, two adults, and the heat pump models are roughly double the price of a condenser where I am. The cycle times…
1978 two storey, upstairs is freezing in winter and the top of the stairs is a wind tunnel. Our utility offers a free walkthrough audit and there is a local firm quoting about 400 for a blower door test, thermal imaging…
Weekend van, a 100 Ah battery, a compressor fridge that draws about 30 Ah a day, plus phones and a laptop. I've been offered a folding 120 W briefcase panel secondhand and I'm trying to work out whether that…
