How To Choose The Best Hot Tub Heater – Buying Guide



When it comes to hot tub heaters, there are three options to choose from which are either gas, electric or solar. They all have their advantages and disadvantages and here we will go through them to see which one would be the best choice for you.

Gas Heaters – One of the most practical solutions if you have natural gas running into your home would be to use a natural gas heater and there is also the option of having a propane heater as well. The initial set-up cost for these types of heaters are generally less expensive than any other option.

Not only is the initial set-up cost less as well but they are generally cheaper to install too so if you’re looking for a low cost option then gas would be the number one choice in this aspect. They are highly effective and get to work very quickly to deliver that hot water.

The drawbacks though are that these units take up more space than their rivals so they are harder to hide away but the running costs are significantly more expensive as the cost of the gas to run the hot tub heater is more than any electric or solar solution.

Electric Heaters – The electric heater pros and cons are effectively the same as the gas heater but in reverse. The initial set-up cost can be fairly expensive which can put off a lot of people and the installation of the item can be more expensive as well.

If you can afford this initial set-up, then great, as the running costs are less which means that you could well be saving money over time. They don’t quite get to work as quickly as a gas heater but take up less space as the units are usually much smaller.

Solar Pool Heaters – These are the rarest types of heater on the market and that is for a few significant reasons. They can be expensive to buy and install but the upside of that is the lack of operating costs as the device will be getting all its energy from the sun.

That though is perhaps the biggest problem as you are reliant on the sunshine then it might not heat up your pool much, if at all. These should only be considered by those in very hot climates otherwise you could find yourself in a situation where you simply can’t heat your spa.
