home at a time.

Hey, Riversdale, meet HotBot™

The award-winning smart geyser controller fixing loadshedding one home at a time.

Saving just got easier: your geyser is getting an upgrade! Hessequa has joined Project Smart Geyser in collaboration with Plentify to bring HotBot to your home.

HotBot is a smart geyser controller that saves you money on your electricity bill, alerts you to leaks, and brings you intelligent control at your fingertips. All this can be yours for free as part of this project to fix loadshedding by shifting electricity usage out of peak times to better balance the demand on our electricity grids.

It’s about time for an upgrade

Geysers are responsible for
40 – 60% of your electricity
bill

Electricity prices have
increased 5x in the past
10 years

A typical geyser bursts every
5 – 10 years due to undetected issues

Traditional geyser timers
work in isolation and can
contribute to loadshedding

We created HotBot so
everyone could save

Here at Plentify we don’t like loadshedding or cold showers either. So we created HotBot to do a better job at saving energy than we could. By intelligently controlling your geyser, HotBot’s powerful AI shifts electricity demand away from peak times, when the South African electricity grid struggles the most.

We’ve got HotBot at work in our own homes too, so we go out of our way to make sure HotBot is working optimally. HotBot adapts to make the most efficient use of available energy. This means you’ll have hot water when you want it and save energy when you don’t.

Thanks to Project Smart Geyser, your home could be one of the first 100 in Riversdale that will have HotBot at work for free!

Small, smart steps lighten the energy load for everyone

Take a load off with Loadshedding Aware™

No need to lift a finger – HotBot pro-actively heats water in anticipation of loadshedding. It prioritises when you want hot water while still working out the best time to save.

Only pay for the hot
water you use

HotBot helps you save up to 30% energy heating water and syncs up with other HotBots in your area to create the most efficient heating schedule. You save, and so does everyone else.

No more guessing

Set when you want hot water – not when you want your geyser on – and HotBot works out the best time to save. A powerful intelligence engine at your fingertips gives you full control over your geyser.

Be in the know

Most geysers stay warm even when they’re not heating. Take advantage with live temperature updates. No more climbing into small spaces – simply update your geyser’s maximum temperature right from our app.

Stay flexible

Even a good routine needs some room for unexpected plot twists. Override the schedule at any time or use vacation mode to make sure your geyser isn’t wasting electricity while you’re away.

Never worry about
leaks again

HotBot’s smart sensors detect leaks and monitor your geyser’s efficiency so you get notified in real time if anything goes wrong.

Be smart like HotBot

Not only does HotBot’s intelligence engine learn and adapt to your hot water shedule, it helps you form better energy habits. Get insights on how to save more and reduce your impact on the grid.

Get rewarded with HotBot™ savings

Because HotBot helps you achieve your energy saving goals each month, you can save up to 30% on your water heating costs. That’s the equivalent of 200 – 300 free showers a year!

What if I have a timer on my water heater?2022-10-06T10:05:24+02:00

HotBot should become the only way you control your geyser’s electricity use. That means you need to make sure that you remove or bypass any timers or other geyser controllers from your home, and rather manage your hot water through the app.

How does my HotBot help fix loadshedding and enable more solar?2022-10-06T10:05:02+02:00

Demand for electricity is not flat, rather it peaks in the mornings and the evenings. Our electricity grid struggles the most during these peak periods, when available electricity supply often falls short of demand and Eskom burns a lot of diesel to try to keep the lights on. Often they simply can’t keep up, or need to save the diesel to serve other times of the day – leading to loadshedding.

Solar by itself is not the answer as it produces most energy during the middle of the day, and does very little to address our peak problem.

HotBot solves both of these problems. Your HotBot can coordinate with all other HotBots to intelligently shift energy demand away from times when Eskom is burning diesel or we’re at greatest risk of loadshedding, and towards times when more solar energy is available – while making sure that you have hot water when you want it.

Why are you giving HotBots away for free?2022-10-06T10:04:34+02:00

Project Smart Geyser is sponsoring 100 HotBots in Riversdale. This project brings together partners, including EEP Africa, the City of Cape Town, Hessequa and GIZ, to improve energy reliability and efficiency in South Africa. This sponsorship means we can get HotBot technology out there so together we can end loadshedding.

By getting a HotBot, you’ll be part of a groundbreaking project that shows how Hessequa is at the forefront of creating a clean energy future.

Will my municipality control my energy use?2022-10-06T10:04:10+02:00

Your municipality will not control your energy use. Instead the system starts by making sure you have hot water when you want it, and heats in a way which saves you as much money off your electricity bill as possible.

After that, heating will be adjusted to meet a combination of three goals: avoid using electricity during peak times (when electricity is dirtiest and most expensive to generate), ensure that geysers don’t all heat at the same time (to avoid putting excessive strain on our electricity infrastructure), and heat as much as possible during sunny times. Your municipality will not have direct control of your geyser.

What happens after 24 months?2022-10-06T10:03:48+02:00

You will receive 24 months of free service, thereafter you will be notified that you can choose to continue the service for a small monthly fee or cancel our service (at no cost to you). We believe you’ll quickly see the value that HotBot can bring to your home. Our aim is for HotBot to pay for itself from the money it saves you on electricity each month.

How does installation work?2022-10-06T10:03:18+02:00

After you place your HotBot order online, you will receive a link to book a convenient installation time. A HotBot-accredited technician will arrive with the device and install it for you. Once HotBot is installed, you can register on the Plentify app and start saving! 

HotBot is a small device (17cm x 15xm x 6cm) which is installed adjacent to your existing geyser. The power to your geyser is run through HotBot, and it has several sensors which attach to your hot water system. You can expect the installation to take about 2 hours to complete.

What if my hot water system is non-compliant with regulations?2022-10-06T10:02:54+02:00

HotBot still works with geysers despite most non-compliance issues. Depending on the nature of the non-compliance, certain features may not work. For example, some hot water systems allow valves to drain into the drip tray instead of being directed outside with a pipe – in these cases it is not possible to distinguish between this and leaks. Our technicians will notify you of any compliance or other issues that they find with your geyser, and can assist in rectifying at your cost if you choose.

Will I have hot water?2022-10-06T10:01:40+02:00

Definitely! HotBot is designed to ensure that you have hot water when you need it and save you money when you don’t. You tell HotBot when you want to use hot water and it works out the rest so you always have hot water at scheduled times. If you forgot to schedule a time, you can always turn your geyser on in the app to start heating your water immediately. HotBot brings you savings by reducing energy which would have been wasted. That means you have the same hot water experience, while using less energy and saving money!

What happens during loadshedding?2022-10-06T10:01:02+02:00

HotBot cannot heat your water if you experience loadshedding over the period when your geyser was heating water. This means that your water might not be hot enough until your next schedule. You can check your temperature on the app and turn your geyer on before your zone is scheduled for loadshedding.

How much will I save?2022-10-06T10:00:39+02:00

Our users save up to 30% of their water heating costs compared to leaving geysers on 24/7, with most saving 15-20%, and some less.This is about double the savings you can expect with a simple timer or by manually switching your geyser at the distribution board.

Actual savings depends on many factors – most notably how well insulated your hot water system is, and how much hot water you use relative to your tank size.

Is there an app for my phone or tablet?2022-10-06T10:00:17+02:00

You can manage your geyser from any device using the web app at my.plentify.io.

Can I cancel? What if I move house?2022-10-06T09:59:49+02:00

The initial commitment is for 24 months from installation. Thereafter, the service continues on a month to month basis, and you can cancel anytime with 1 month notice.

If you want to cancel within the initial 24 month term, you will be liable for a R3,000 cancellation fee, to cover the cost of installation, removal and refurbishment. If you move house within this period, you can either have us relocate your HotBot (for a fee to be quoted at the time), or have the new residents take over your HotBot for free for the remainder of the 24 month term (in which case the cancellation fee will be waived).

Should I turn my geyser on and off at the distribution board?2022-10-06T09:59:27+02:00

Avoid switching your water heater on and off at the distribution board. This can reduce energy savings and prevent leaks and other issues from being detected. Instead, manage your water heater from the app at my.plentify.io.

What should I do when I leave town?2022-10-06T09:58:42+02:00

Set your HotBot to vacation mode to save money and energy when you’re away from home. HotBot will make sure you have hot water ready for when you get home again.

What happens if there is an issue with my geyser?2022-10-06T09:57:26+02:00

You’ll automatically receive an SMS letting you know if we’ve identified any issues or suspected leaks with your geyser. We suggest you or a plumber inspect your geyser to confirm any leaks. You will need to pay for any call out fees or repair work.
