Considerations When Choosing a Bathroom Heater

Choosing the Right Output

When choosing a new heater for your bathroom it is important to take a couple of things into consideration with regards to the wattage and output before buying. 

By choosing a heater of lower wattage, around 1000W, you will generally get higher energy efficiency with lower heat output and slower warm-up times. In the long run, this can lead to less money accruing on your energy bills.

Conversely, you may find that choosing a lower wattage heater may not be effective enough to heat a larger bathroom. 

When choosing a higher wattage output such as 2000W you also have to bear in mind that, if left running for longer periods, the total energy required to keep up the operation of higher consuming heaters may lead to lower efficiency.

That being said, if you are wanting to warm up a room quickly, then choosing a higher output may be the most practical option. 

Safety First

When choosing a new heater, it is always best to check out the safety rating of each, this includes the IP Rating. The IP rating of a heater determines how waterproof it is.

For example, a rating of IPX4 is highly resistant to water, whereas a rating of IP0 would be considered not suitable for use around water. Naturally, when using a heater in a bathroom you would ideally require some level of splash proofing in place for it to be fit for purpose. 

As a second point, when considering the safety features of a heater for your bathroom, it is important that you consider the inbuilt technology, designed specifically to prevent overheating or overuse.

These are desirable features to have in a heater, especially if you find yourself having to run back to the house and turn your heater off.

Having inbuilt safety features is a perfect way of removing an unnecessary worry, if your heater features anti-overheat capabilities, you will never have to worry about leaving it on by mistake, only for it to break due to overheating.

Similarly, utilising a heater with an auto-cut off function will allow you to use the heater without the worry of it running up a huge electricity bill.

Summary

For the best choices, the Winterwarm WWDF20E or the Glen GDF20E are great value for money, with the most effective and efficient products.

It is a tough choice, all these heaters are packed full of features. The choice ultimately comes down to how you intend to use the heater, what features you find are more suited to your needs and the size of the bathrooms you wish to heat.

A 1000W heater is perfect for a smaller space as well as efficiency in the long-term, whereas a 2000W heater will give you fast, satisfying heating but at slightly less efficiency.
