More #FirstWorldProblems as my new hybrid heat pump hot water heater failed city inspection. Apparently the plumbers will have to redo the condensate drainage, as the plan of "empty the bucket" isn't going to cut it, it must go into a sewer drain or be piped outside.
Other people are going away for the (US) holiday weekend, barbecuing, hiking, whatever. I'm hauling gravel. The garden show is a month from yesterday. The countdown is on! I'm terrible about taking "before" photos but trust me this is a big improvement. And why yes, that is an electric #heatpump on the right there in photo 1. 5 stars. Would recommend. #gardening #PNW #inmygarden
My landlord installed a heatpump / electric combo water heater last month. It has a wifi connectivity feature that supposedly lets you schedule the water heater.
I was excited to be able to turn it off during peak times (4 to 9pm) and at night and set it to high efficiency mode when needed.
The inverter #heatPump, which refuses to operate at temps below 40F, has still been pretty useful this pnw winter. But what if it could charge up a room-temperature phase-change thermal battery running on solar electricity in the daytime? Radiator full of wax plugged into the window unit or hung off the inside of it... 🤔
You work in IT and want a job where you can really save tons of CO2? Vamo, a heatpump startup, is looking for people to join their IT-team to help them connect heatpumps to the cloud!
What is a #HeatPump clothes dryer doing with 240V 30A just like a resistance heater unit? Is it going to try 4x as fast or just rarely draw more than 5A? I was thinking that change might free up a double-pole circuit in the panel, but no? Could it at least share with the heat pump water heater?
Over a month ago I promised a blog on my Heat Pump and Solar Panels and Battery Storage.
I've finally hit "publish" (well, actually "rsync" but whatever)
It may, or may not, answer any/all questions you have about this. If not, maybe ask me here and I'll try to reply and forget to include that in a future update.
We just received our "jaarafrekening". This is the final yearly invoice sent by our energy company. They are about to pay us €252, and we will continue to pay them €5 per month next year, just like last year. i.e. overall our energy company is paying us about €200 for last year's electricity. Everything in our home is powered by electricity. No gas connection. No wood burner.
Nothing that we've done to achieve a negative energy bill was especially expensive. In particular, our installation of a air-air heat pump and a couple of extra solar panels cost far less than several of our neighbours paid for the wood burning stoves they've installed, which stink up the neighbourhood all through winter.
We also don't have to buy wood to burn.
People concerned about the cost of heating with gas buy woodburners at a higher rate than heat pumps largely because they have no idea about the relative costs. If they knew, perhaps we could have clean air.
I'll write a comprehensive blog post at the end of March about energy consumption, costs & emissions due to the heatpump vs. gas this winter. I can tell you already that we using a lot less total energy now.
Just watched the latest video from @mattferrell which is extremely timely for me. I posted a blog post earlier today where I mentioned I was wanting to get a heat pump water heater, and a few hours later Matt posted this: https://youtu.be/abGiNL9IT54?si=w_GyCuD47w4Yn-H4
Planning permission submitted. £322. I used #SmartDraw to do the elevation. It is a really good web based application. I had forgotten about it.
It is shame I couldn’t subsribe for one month. Like many other sites they mention a monthly subscription, but it is billed annually. You can’t subscribe for just one month.
#HeatPump tip - download your gas usage data from your supplier BEFORE disconnecting your gas account, as in my case EDF have deleted it, so I can't compare my energy usage before and after the heat pump :(
