"Smart room-by-room heating control for homes"

Imperial MSc Computing Science students do a 3-month individual project over summer. Below is another proposal I and my Ph.D. supervisor have just submitted. Of course, there are no guarantees that any students will be interested...

OpenTRV: Open-source home heating control

This project looks like it could be the start of something I've been after for years: Open-Source Thermostatic Radiator Valve (OpenTRV)

Gas consumption 2007-2011

I've finally gotten round to plotting our gas consumption on a graph. I'm not expecting a measurable drop in our consumption yet. We finished insulating our living room in July 2011 and I'm only just getting round to insulating our bedrooms (Feb 2012). We installed a new condensing gas boiler and solar thermal in July 2011. But we also had a baby in August 2011 so we've had the heating on far more than normal for the last quarter of 2011!

Temperature data from the Heathrow MetOffice weather station

What does this data tell us? And why did it take a fair amount of effort to plot our gas consumption?

Existing central heating control systems

A little while ago I wrote some notes describing my "ideal" central heating control system, which I was planning to build myself.  Time is short so it looks like this system won't be built for a while so I need something which I can buy off-the-shelf which will satisfy as many of my requirements as possible and also leave the door open to DIY tinkering in the future.  This blog post is a collection of notes about off-the-shelf central heating control systems.

Insulating our Victorian living room part 2

We live in an end-of-terrace Victorian house, built around 1905.  I've spent the last few years insulating our living room.  This blog post is the second in a two-part story.  By the end of the first part of the story, our living room looked like this:

I'm pleased to say that our living room now looks like this:

One big design change since my last blog is that we decided to install wet underfloor heating ourselves.

So, let's start the story...

A better central heating control system

Update: The following blog describes my "ideal" central heating system; the idea being that I'd build this myself if I got the time. It looks like I won't get the time to build this any time soon so I've started looking at off-the-shelf solutions. My research on off-the-shelf solutions is detailed here.
