While our website has been primarily dedicated to natural gas water heaters, which to date is still the most powerful and energy efficient way you can heat water in your home on demand.
That said, we can’t ignore the fact that we are emitting carbon dioxide in the atmosphere to heat our water, and they don’t work in off-grid situations. So, I think it’s time we talk about the merits on an electric tankless water heater.
The technology has come a long way over the last 10 years. In fact, some of the best electric tankless water heaters units can provide up to 4.0 GPM of on demand water, so simply having two of them is enough to replace even the most powerful natural gas unit. There is very healthy competition in the category meaning several brands are coming out with more powerful, more efficient and most importantly, cheaper units each year.
After having a look through the different units available, I am confident that now is as good a time as any to replace your natural gas tankless water heater with an electric one. You may pay a little more for electricity, but you will stop emitting and contributing to global warming, which can make you sleep better at night.
We hope this sheds some light on making the decision to replace a natural gas (or old hot water tank) with an electric tankless water heater.
When presented with the option of purchasing a propane or natural gas tankless water heater, many people have some difficulty making the choice.
While we acknowledge our bias for Natural Gas, it is indeed the right choice in the majority of cases. The simple fact is, natural gas is both cheaper and more readily available via direct lines than propane, making it the obvious choice for the majority of homes.
But we know that, it’s common sense, so this article will go over the particular cases when propane heaters make the better choice.
When you’re on the road in your RV!
RVs generally go with either an electric tankless or a propane tankless water heater. Sure, the electric might do, but in those cold winter months you might need something more powerful than a tiny ecosmart to get the temperature rise you need. This is where propane water heaters come in to play, with the ability to heat water to over a 50F rise, even in water at 32F! A tankless water heater could never achieve this type of result.
Of course, if you are out during the summer, you might want to look into infrared water heaters. The iWP Foundation makes the best recommendations on tankless water heaters for RVs.
When you’re camping, cottaging and enjoying the outdoors
If you are camping, you don’t have the option (real camping, anyway) to use an electric outlet for a water heater, so propane becomes the right choice. There are many kits and adapters to make that regular stove propane tank hook up to a propane water heater for a great outdoor shower. Keep your bathing suits on! Your nosey neighbors might even want to share in the fun 🙂
If you have a party of 4 or more, you may even want to bring a full blown BBQ propane tank so the whole crew can enjoy showers.
If you don’t have a natural gas line to your dwelling
In northern states and in Canada, electric tankless water heaters don’t have enough power to heat water sufficiently in the winter months. That said, many homes in those areas don’t have access to natural gas either. That leaves either an electric tank or a propane tankless water heater as options. With the tremendous energy savings of a tankless water heater, it may very well be cheaper to switch to a propane tankless from your electric hot water tank.
In emergencies and black outs
Maybe the most overlooked of all, but in the case of a grid failure or other type of emergency, having access to a propane water heater can prove very nifty indeed. Think about it, if you had to go 2-3 days without a hot shower, you would do almost anything for that relaxing touch of warm water. It never hurts to be prepared, just make sure that propane tank is stored carefully!
I hope this article shows that while natural gas tankless water heaters are the obvious choice for most people, propane water heaters certainly have their place as well.
