In our prior article, we explained what a tankless hot water heater is and how it compares to a typical 40 gallon tank hot water heater.
- Endless Hot Water
The difference between your standard water tank heater and tankless is that a tankless supplies the hot water ‘on demand’. So if you need a shower any time of the day, you will get hot water when you want it and it will never run out! You can use up all the hot water in a tanked heater – which can be very frustrating if you are last in line in the morning for taking a shower.
- Energy Efficient – Saves Money!
One of the biggest pros of tankless water heaters is the running costs. Water heaters are the biggest contributor to energy bills so does a tankless water heater save you money in regard to running costs? Well the straight answer to that is YES.
When you heat water in a conventional tank, the water will slowly cool down over time thus you are wasting energy and as such needs extensive insulation. As a tankless heater is real-time, there is no need for insulation and is only on when needs be therefore it by default is more efficient. Figures show that you should save 30% energy, some even say this can go up to 60%.
- Space Saving
A tankless water heater only needs a little space compared to a conventional water heater, this is a god send especially in small apartments. If you are thinking about building a new home, that's a great time ot install a tankless water heaters.
A conventional water heater typically has a life span of upto fifteen years (this depends on how you look after it of course!), but a tankless water heater should last ten years longer (looking at 20-25 years on average). Compared to a tanked water heater which generally lasts 10 -15 years
- No chance of floods
One of the biggest concerns with your conventional tank is the potential for leaking issues, there have been many instances of flooded houses when the heater has ruptured. With a tankless, there's no tank, thus no chance of any unexpected floods.
As you can see there are many positive reasons why you should purchase a tankless water heater, but before you get carried away you should also consider the negatives below.
- Initial Cost
A big disadvantage with a tankless model is the actual cost of the heater. You may find that the cost is up to three times as more as standard water tank heaters, however these prices are coming down and are more comparable to your standard hot water heater.
One of the real cons of tankless water heaters is the need to modify your house when installing the tankless model.
If you purchase a gas tankless heater you will probably need to install a sealed ventilation pipe to exhume and supply air in safely which will result in extra costs plus you may even need additional gas lines in the house. These factors need to be weighed in before purchasing a water heater. Even electric tankless heaters may need some special installation like additional circuits.
If you have an older house, generally speaking the installation costs will be greater.
- Multiple Use Problems
As it is on-demand it can only supply a certain amount of hot water at that point, if you want to run hot water in the kitchen and the bathroom at the same time you will find that you won’t get hot water! If you have a large family this may cause some problems. You may need to consider installing multiple tankless water heaters, this stand true for larger houses.
So after looking at these tankless hot water heaters pros and cons, which one should you purchase? This depends on your situation. But if you are looking to replace your water heater then you should strongly consider a tankless water heater, over time you should earn back the money spent on the initial cost – plus you will not need to maintain as much as the standard tank heater.
The last question is, Are Tankless Water Heaters Worth It?
Hope This Helps!
