Pros And Cons Of A Tankless Water Heater


Are you looking to update your home’s water heating system? Have you considered changing to a tankless water heater? There are many ways that they can improve your home’s energy efficiency and reduce the total amount of water used.

Pros And Cons Of A Tankless Water Heater

This is a look into the pros and cons of a tankless water heater worth noting, so that you can be fully aware of the maintenance, additional costs, and estimated lifespan of a tankless water heater.

What Is A Tankless Water Heater?

The tankless water heater is a type of appliance used in residential and commercial applications to supply hot water without using a large tank to store hot water. These work by heating water as it flows through its internal pipes without having to rely on a large storage tank. This makes the unit much smaller than a conventional water heater that has a tank inside. They usually have more modern displays than other thermostats, which allows accurate and easy temperature adjustments when necessary.

There are many ways that you can take care of your tankless water heater, and it is recommended that you use a tankless water heater flush kit when needed. Tankless water heaters are an ideal choice for those who are living on the road in vans or RVs because they can make the entire rig might lighter in weight. In turn, this can help increase engine efficiency and save space on the road.


Energy Efficient

Firstly, tankless water heaters only heat the amount of water required, rather than storing it in a tank ahead of time. This means that there is the chance to greatly reduce your home’s energy consumption and decrease the amount of fuel which your home or RV is using. Both electric and gas models are available, which means that you can get a tankless water heater regardless of your home’s energy supply.


Because water storage tanks are pretty bulky, they are located further from the faucet. This means that it can take a little time to access the hot water. Tankless water heaters do not have this issue, which means that it takes less time to get hot water when you need it.

Save Space

Another benefit of tankless water heaters is that they save a great deal of space. This is ideal for someone who lives in a smaller home, or even an RV, where space is limited. Water tanks take up a lot of space, which could be used for storage or keeping emergency supplies nearby.

Long Warranties

Tankless water heaters are also an ideal choice because they often have a relatively long warranty period. This means that your water heater will be repaired or replaced if it is faulty or broken in some way. There is a guarantee that these products have, and the manufacturers want them to last a long time.

Installation Costs

One of the biggest drawbacks of tankless water heaters worth being aware of is that they can be a little more challenging to install. This means that the installation costs and other initial expenses can be relatively pricey. On the other hand, the amount of money saved in the long run through optimizing water efficiency balances this out. It is a little challenging to install tankless water heaters on your own if you are less experienced with plumbing fittings, so it is recommended that you allow for installation costs initially.

Limited Supply

Another thing to consider before purchasing a tankless water heater is that they have a limited hot water supply when they are used for multiple outlets. Because of that, it is recommended that you are mindful of the number of faucets which a single tankless water heater is feeding into.

Additional Equipment

Tankless water heaters can also require additional equipment in order to maintain them and make them last longer. These can allow your water heater to function correctly and allow you to get the complete range of benefits. Because of this, it is also worth allowing a little room in your budget for these items if possible.


A tankless water heater isn’t for everyone, but it can be a great way to save money and encourage everybody you live with to be a little more mindful about their water use. These tools can be ideal ways to promote more sustainable living and reduce the cost of utility bills in the long run. Tankless water heaters are also ideal for RVs because they take up less space and do not weigh as much as a water tank.
