Title: Heat meter
Post by: heatherhopper on May 07, 2019, 03:01:45 PM
Anyone have any recommendations for a heat meter?
This would be just for personal understanding of my system and not for critical/control or regulatory monitoring/recording.
Don't want to splash out on anything too high end but equally don't want a pup. Preferably not something originating in PRC or the like.
I am interested in both positive and negative experiences to help whittle the candidates down a bit.

What is it your looking for? Air temperature? Water temperature? Something else?

What I have been after for a while (and am still trying to find at a sensible price) are temperature and humidity dataloggers that connect to a central server... So I could have 1 per rooms and log temperature and humidity to a database/dashboard somewhere and consume the information later (tied up with the weather logging, central heating logging, gas consumption, electricity consumption and solar generation logging that I already have in place). That would satisfy my inner data nerd for a while!

Have a look at the open energy monitor shop https://shop.openenergymonitor.com/components/ (https://shop.openenergymonitor.com/components/)

Apologies - maybe I should have been a bit more specific.
I am after a heat meter for measurement of the thermal energy used for space heating and domestic hot water. Sometimes called a Flux Calorimeter I think.
I already have fairly comprehensive monitoring of all other energy inputs (openenergy based) and would like to add the thermal energy balance to the data set.
Pulse output meter ideally but manual read might be acceptable.
Kamstrup, Sontex etc are examples of manufacturers but there many more.

Plenty on Ebay  https://www.ebay.co.uk/itm/Sontex-heat-meter-Superstatic-749-Qn2-5-3-4/264313307208?hash=item3d8a4d0048:g:7zYAAOSw~BFcxFZv  Once they have been used they cannot be reregistered to ofgem. Lots of useless second hand units lying around. Call your local biomass company.

Thanks Rogeriko - I'll have a look at second hand possibilities. Still interested in which might the most best makes though.
Interesting that there may be so many s/h items available - why is that? Unnecessary upgrades, poorly considered biomass installs or just too much effort required?
