The story of my #heatpump journey. Big thank you to all the bluesky folk who have helped on the way!

People of Bluesky!! How do you track your central heating, if you do? Spreadsheet and regular meter readings? Heat meters on your pipes? A smart meter? Anything more unusual? PLEASE TELL ME! Working on a story about this.

It happened, Nathan finally got me on the Beta Talk podcast. “Don’t drink, don’t smoke, what do you do?” betatalk.buzzsprout.com/509671/episo... We spoke for ages about a load of stuff and mentioned a ton of people. @octopus.energy @energystatsuk.bsky.social @openenergymon.bsky.social

Was wondering why my DHW COP was so poor on @openenergymon.bsky.social but thanks to @zarch1972.bsky.social excellent blog - energy-stats.uk/arotherm-plu... - I realised I've been running it on normal as opposed to Eco. Will be interested to see what difference it makes. emoncms.org/app/view?nam...

The Tracker tariff rollercoaster. 🎢

I spy with my little eye 22:30. 👀 Looks like it might be worth hanging off a day with any big charging? 🚗

My latest video is up. In this one, I look at how my low flow temperature actually uses *less gas* than the traditional 70° flow temperature that I'm told is better! youtu.be/lig23gactEo

Do you hot water runs in the afternoon for best COP they say!! Well, not much in it during the winter so far. Especially if you do the hot water runs on cheaper rates. Just keep them overnight? Interesting numbers from my Mixergy and 5kW Arotherm in Eco mode (to 45C target) since 1st November.

I run a podcast to help people understand heating. I can waffle on (sorry) but I do have some great guests who are great to listen to. Check it out & pass it on betatalk.buzzsprout.com

This evening I've been doing some max output testing with a Vaillant 5kW ASHP, at 0C with 45C flow Vaillant claim an output of 6.6kW is possible, however in real world taking into account defrosts it only managed to output 5.3kW, which is 80% of the stated output

The weather forecast suggests colder days ahead this coming week, but the heat pump is looking good again and performing well as we head into its third winter. Monitoring by @openenergymon.bsky.social energy-stats.uk/my-5kw-vaill...
