Description

We have designed a data recorder that indicates in 15 minute blocks whether a domestic electric storage water heater was used or not. The data is purely yes/no, so it might read 1,1,1,0,0,1,1,0,0,0,... where a one means it was used and a zero means it wasn't.

The heater wastes energy when it is on but not used, so we would like to use this data to forecast the next few values of the data series, perhaps with a confidence level (say the probability it will be used). We would then switch the water heater on only when it is reasonably likely to be used. We want the rules to be implementable in a C program so they would need to be simple.

It is quite likely the data will display fairly clear patterns based on time of day and day of week and it is also likely that there will be long periods periods of constant non-use at night say. So we could perhaps look for regularities based on daily and weekly cycles.

We are looking for a practical solution that works and is easy to implement - it need not be backed up by statistical theory if this is too difficult.

We could simulate some plausible data but don't yet have real data.

Greetings England from the USA.. On and off state comes with ramifications. For example, a boiler does not go from 0 to full in an instance, correct? Which brings us to the whole point, how much does it cost to operate the boiler in each separate state of shutdown, standby, and full operating state? And you want this codes in C - a principally text based programming language? No charts? No regression graphics? Just pure and simple slope numbers and intersects? Great choice on your part. Finally, I can only assume that the cost savings of a well implemented version of this problem is only about $30-250. Or would that be gross overspending on your part? Oh well, you get what you get what you pay for.. and for $30 you are going to look absolutely GREAT at your next operational staff meeting. Hello my name is Bill..

Hello, I am a Canadian Mechanical Engineer with close to 20yrs analysis experience. I will mention up-front that your concept might be impractical... To save money on water heating, there are commercially available "instant hot" water heaters that are extremely energy efficient and function only "as needed". That said, nonetheless, there could be a market for an inexpensive retrofit to common hot water tank systems. I believe your project needs a bit of research because it is easy to say "turn the heater off when it is not needed", but then when off, the water in the tank will gradually cool. There will be an ideal schedule where the energy needed to re-heat the water will be less than the energy needed to maintain it hot. Another complication, is how much inconvenience a consumer will tolerate? What if on rare occassion, he/she returns home late from a party or night out and needs a shower to wash off the night's grim... no hot water... Again, the application might be impractical for residential use... but maybe for office buildings and the like, where schedules are much more predictable. At any rate, I am more than willing to lend my consulting expertise to you; I wish you great success with this "green" initiative!
