Consider Before Buying the Best Steam Shower Generator
Before buying a steam shower generator, there are a couple of things that you need to consider. These are:
Power Rating
Measured in kilowatts, a steam generator’s power rating should be the first thing to consider.
A higher power rating means that the unit can produce more steam faster, which is good especially if you have a large steam room. However, this also means that it consumes more electricity and therefore, you should expect high power bills.
On the other hand, a low power rating means that it consumes less electricity, but produces less steam and at a lower rate. This makes such a generator suitable for smaller shower rooms.
Room Size
Following up on the power rating, you should measure your room size based on the generator manufacturer’s guidelines, then determine if the respective product is suitable for your shower.
Usually given in cubic feet, this suitability always goes hand in hand with the power rating and thus, if you have a bigger shower space, you will need a generator with a higher power rating that can comfortably steam up your whole space.
Fittings
The fitting size of your generator’s inlet, steam head, and drain valve should also be put into consideration because they show you the size of pipes and connections that you will need when installing the unit.
A half inch is the most common size but some might have 3/4-inch heads, which then require the respective fitting size pipes.
Auto-drain
This is a really important feature that you should consider. Basically, with auto-drain, the generator will automatically flush out any water in the boiler tank after the steaming session and this helps to avoid mineral build-up and rust, giving it a longer lifespan.
Accessories
Accessories are always an added plus and in the case of shower generators, some come with their own control panel, eliminating the need to spend further when doing the setup. Others even come with chroma therapy lights for improving the steaming experience.
Generally, the more the accessories, the more you should consider buying the steam generator.
Warranty
Since it an electrical appliance, you should only buy a steam shower generator with a warranty that covers it for at least 1 year. Since most come with limited warranties, it is important to check how much it is limited so that you do not get a raw deal.
The most basic one should at least cover all manufacturer defects for that specified amount of time.
Conclusion
Steam shower generators are very good for your shower but as you can see above, they can be very challenging to buy if you do not know what to look for.
However, after reading through this article, you should be in a better position to pick the best steam shower generator that suits your needs.
