Going Green – Getting Started

Setting The Plan In Motion

As with most of my plans, change is inevitable!

The original planning was to do the solar water heating retrofit, followed by change to gas for cooking then adding an inverter with solar PV panels and then adding a battery storage system.

All of that got turned upside down after a couple days of very inconvenient load-shedding.

I decided that it was time to convert to gas and to get a battery backup system installed as soon as possible.

The Gas Stove Installation

First order of business was to find a gas stove and oven to replace my existing electric hob and oven. I finally found a nice stove at a decent price from Hirsch’s:

So, taking a chance by not consulting with the boss (my wife) I went ahead and ordered the stove so I could at least cook when the lights went out again.

Before this could happen, I would need to arrange for a legal gas connection, get 2 x 19kg cylinders, a gas cage to house the cylinders and then strip out the existing equipment and modify the kitchen counter to suit the new stove.

Three days after ordering the stove it arrives and I can’t wait to get it installed and working.

I decided to use the upcoming weekend to strip out the old stove and get the kitchen counter sorted out. The following Tuesday the gas installation would be done and we’d finally be cooking with gas, so to speak.

The old stove got removed and the counters sorted out without too much hassle.

This left me with no stove for the weekend, but I managed to make a temporary plan, after all, the installation would be complete by Tuesday evening, so no problem.

Problem! The installer could only come do a quote and because of all the public holidays at the end of April, the installation would only happen the following week! My temporary arrangement would have to last a bit longer.

Finally, ten very long days later the installation got done. Mission accomplished: Wife happy again!

The Costs

Trying to figure out a payback period for this installation, isn’t easy, but here goes:

Costs:

  1. Stove: R6,500
  2. Gas installation: R2,600 (includes compliance certificate)
  3. Gas cylinders: R1,200 (includes cylinder deposit)
  4. Gas cage: R2,100
    Total: R13,400

If I assume that we use the stove once a day for an hour on average with one plate and the oven operating, it would use around 3kWh of energy.

At a cost of R1,65/kWh that gives a cost of R4,95/day

So the payback would be R13,400/R4.95 = 2,707 days = 7,4 years!

All of this excludes the cost of gas refills. Time will tell what our eventual gas consumption is, but I’m hoping to get 6-months out of the 38kg gas we have.

Payback might take a while, but being able to continue cooking when the lights are out is priceless.

Next step is to get the inverter and battery back-up sorted.

More of that to come.
