Digital Heaters and Smart Home Systems

What is a smart home system?

The concept of a smart home is getting more popular in Singapore. What exactly is a smart home and what can it do? Smart-home residences in Singapore allow owners control of several appliances and features usually over the internet or a remotely controlled device such as a mobile phone. Electronics that are commonly linked in a smart system are:

Security cameras

Electronic blinds

Lights

Air conditioning

Televisions

Water heaters

What a smart home system does is connect all these electronics, usually through the main circuit breaker or MCB. The MCB is then connected to a smart home interface, which is then linked to the internet router at home. The interface can record useful data on electric and water consumption. For owners who are particular about their usage, this data is monitored closely so that family usage patterns and electronic settings can be altered to minimize utility bills.

Smart systems allow you general control of your appliances but not detailed appliance control. For instance, you can switch your air conditioner on and off with your mobile phone, but you cannot access more complicated functions available on the remote control such as the blower direction or switching between ‘dry’ or ‘cool’ mode.

If you have a smart home system and an AOS digital heater installed, this article will give you an overview of what you can control on each end.

1. Remote on/off control

The strength of a smart home system is that it allows you to control the power supply to the MCB (and hence the appliance) remotely from the internet. Even if you are overseas, you can switch any connected appliance off and on with ease. You can only do this from your mobile phone or remotely controlled internet devices.

2. Automatic on/off timer

From the smart system, you can set timings on when to cut power on or off to each individual appliance at home, including the water heater. The digital water heater control panel also has a similar timer feature. You can check out the article how to set the clock and timer for the digital panel here.

3. Consumption monitoring

Smart home systems are linked directly to the MCB so they can gather information of electric consumption patterns and display them nicely in graphic format. If you pay more for your smart home system, your water pipes will be fitted with flow interfaces so you can monitor your water consumption too!

Consumption monitoring is a really useful feature and the additional data can be used to fine tune your appliance settings so you can consume less. For instance, if your electric bills seem unusually high for a particular month, it may be that your heater is set at the wrong temperature. In that case, head to the panel to reduce the thermostat!

4. Mode settings

Depending on how many people are living at home at any given point in time, put your heater on different modes to accommodate for overcapacity or reduce unnecessary heating. You can only perform mode selections from the control panel as it is connected with a special data cable to the internal heater tank.

More information about how to use the different modes of digital heaters can be found here.

5. Instant function

If you need hot water quickly, the control panel offers an ‘instant’ function which detects all hot water in the tank and pushes it to user. This is activated by pressing the ‘instant’ button once. You can only activate ‘instant’ from the panel.

6. Thermostat control

Like your air-conditioner, digital heaters allow you to customize your tank temperature. Set the temperature at 70°C for high usage and 50°C for low usage families. You can only adjust temperature from the panel as it is directly linked to the temperature sensors in the tank.

7. Real time temperature visuals

Read off your exact temperature from the panel or glance quickly at the 5 indication bars as a visual guide so you know whether you can go in for a shower immediately without wasting time.

Smart homes and digital heaters are complementary

There is very little overlap between having a smart home system paired with a digital heater. In fact, the systems are quite complementary. This is also the case for other more complicated appliances like surveillance cameras and air conditioners.

While smart homes specialize in giving homeowners a bird’s eye overview on appliances at home, the importance of programming appliances individually is still crucial for saving energy. Be sure to read up well on the features of your items you purchase!

Avoid These 6 Warranty Pitfalls at All Costs

Beware of a Too-Good-to-be-True, Ultra Long Warranty!

Don’t be me. I learnt this the hard way buying my Samsonite luggage. Buying a "lifetime" warranty seemed like the best deal. Until I brought it in to change a part that fell out.

Then they pulled out this crazy list of terms and conditions that made me give up.

For appliances like water heaters, the concept is the same. Not all warranties are equal. Understand this before you buy. Know what to look out for. This will save you precious time and emotional frustration.

1. Keep Your Eyes Peeled for a 'Full Warranty'. This is the Best Type of Warranty and Very Rare. Go for FULL Coverage Whenever Possible.

Full warranties are scarce and hard to find.

Good news is... 'hard to find' does not mean it is impossible to find.

You want this Full Warranty because it protects you more than it protects the company. That is the idea right?

You want to be fully covered to be exempt from paying for hidden costs. This needs to cover everything from labour, parts cost and transport. A full onsite warranty.

The only thing that is not covered are installation faults. But it is fair to exclude this from coverage. If your installer damaged the product because of his lack of skill.. then you go after the installer.

2. Don't Just Get Full Coverage... Get the LONGEST Possible Full Coverage.

When buying stuff at Harvey Norman, they always ask if you want to upgrade your warranty and add 2 to 5 years to it.

While it's always tempting to think, Nahhhh. I've already spent $5k on this fridge!! Why would I want to top up YET another $800 bucks for incidents I cannot forsee??

WELL. Life is about planning for incidents you cannot forsee. And from personal experience, Extended warranties have saved my wallet more than half the time. So grateful for buying the extension for the last few big-cap electronic purchases. I put my faith there!

In Singapore, the average lifespan of a heater is 5 years. This means many heater companies will give you a 1 Year Full warranty.

Better brands last longer, so they go up to 3 Years Full warranty.

If your home situation is long-term, aim for 3 years. You save more in the long run going for quality and the longest possible warranty coverage.

If I don't Have a 'Full Warranty'... What am I Getting?

If what you have on your hands isn't a full warranty... You may have a partial warranty.

In that case, you have to be extra careful.

Partial warranties cover only certain parts

3. Now Hang On Tight, Don’t Fall off Your Chair... We’re Coming to the Most Well Kept Secret About Partial Warranties..

Of course a partial warranty sounds appealing!! Who doesn't like the sound of a 10-year warranty? But they are misleading and even a tad dishonest.

Let me let you in on a secret. A 10-year warranty on a heating element might seem like a great deal.. but the industry secret is that the heating element rarely fails. It’s the other parts like wires and thermostats that will need repair sooner. If these aren’t covered, you could end up paying out of pocket for repairs.

Usually, companies who play this game are not interested in servicing you. They are excited to find out if you’ve exceeded your 1-year warranty. Then they can slap on some charges for back end sales. It's a horrible way to do business.

Be wary of those partial warranties!!

Heating elements are hardly ever replaced.. in all my years of being in the heater industry, I’ve only seen elements break down less than 5 times!!

4. Trust me on This, for Heaters.. Always Buy Local. Forget That Awesome Deal You Saw on Taobao.

Absolutely NO taobao for water heaters!! It will be the worst decision ever.

You need a local warranty. If there's a problem.. there is no way you can fix it yourself. You are not superman!!! Even if you ARE Superman, you have no Time!!

When you buy local, you're actually buying access to a valuable local support network.

I've heard horror stories of unapproved heaters bought online that fail at the worst times. Imagine: Chinese New Year no hot water?!! Your wife and kids are giving you pressure? Now good luck getting support over taobao chat.

Actually, at that point you’ll need more than luck to survive.

Don't ruin things for yourself. Always buy local when it comes heaters. Thank me later.

Heaters are one of the hardest appliances to troubleshoot.

5. Hidden Costs Here, Hidden Costs There, Hidden Costs EVERYWHERE!

If normal transport charges are $100+... Why are you getting charged $250????

I've heard this happen to people who are still locked in under their 'warranty period'. They can't go to a 3rd party to repair or their warranty may be void. It's a minor wire repair but they have to cough up hundreds $$$$$.

They are stuck in what we call a ‘bo-pian’ or no-choice situation.

It is downright dreadful, but sad to say.. This kind of back-end sales tactic has happened before and will happen again.

Out of frustration, some even decide to change their whole heater to another brand. It’s a good move because you avoid dealing with dishonesty.

On the other hand, it’s very expensive…

You can avoid this heartache by doing some homework. Buy from a reputable company.

6. Whenever Possible, Buy Direct from the Main Distributor

When I bought my first Dyson.. I went to a Reputable department store along Orchard Road. They were running a promo I couldn't resist.

Things went fine as long until my Dyson stopped working.. then the nightmares began. I got thrown around department after department of red tape.

Need to check invoice.
Need to look up sales person.
Oh.. Must send to HQ for inspection.
Now we need to order special parts.

It was a simple problem but so many layers of people and paperwork. Drove me nuts.

From that I learnt my lesson, always buy direct.

Now I get my Dyson from the main distributor. Their turnover is fast. I have absolute confidence I'm getting the latest version free from bugs and defects.

If they have issues with a model, they are upfront and transparent with me. Because I am their direct customer, they will take care of me first.

Response is also much faster!!

Sometimes, they also waive charges. Now, I'm not saying to go in with the expectation of free service. Everyone has to earn a fair wage. But I can feel the difference in the quality of customer service.

Same idea with water heaters. Want faster service? Buy direct.

7. Are You Serviced By a Bot or a Human Being?

Of course you can tell. Everything is different when it's a real person on the other end of the line.

Service is faster.

Arrangements are flexible.

You get accurate answers.

Because a real person understands your needs. A bot doesn't.

Conclusion

Singaporeans and hot water have a special relationship. We take it for granted when it is there, but we go crazy when deprived of it!!

Understanding your water heater warranty can make or break your hot water experience.

Hope the tips I’ve shared here on warranties will help you in some way!
