KMH-20 - Infrared Heater

2000 Watt - 1 Heat setting, Light reduced low glare-heating.

Stay warm whilst the sun goes down even in Winter!

Do you want to stay warm all year round in your favourite outdoor area during the colder months?

Do you want to sit out longer at night on your balcony or terrace?

Do you want to extend the outdoor sitting area in your restaurant?

Then look no further than the KMH-20 Infrared heater! Allowing you to sit outside late into the evening. This heater is better for restaurants as it can be linked to a series by an electrician and turned on/controlled by the owner and not the customers.

Perfect for PIR and Timing Installations

This heater is perfect for restaurants/bars that are using PIR and Timing Installations as the one heat-setting can be easily controlled by the owner.

KMH-20 - Low Glare - High-Quality Device

The tilt angle on this heater can be adjusted 45° upwards and downwards, this allows you to target the heat rays to your preferred area.

We have designed this heater using modern low-glare infrared radiation technology, the KMH-20 works extremely energy-efficient without preheating, with 80% less light and no noise!

Finally, the sleek design of the KMH-20 adapts to any environment perfectly.

IP65 Rated - Water-resistant and Robust!

The KMH-20 is IP65 rated, the highest rating on the market for an Infrared heater. IP65 means that this heater is "dust tight and protected against heavy rain or powerful jets of water". This means that this heater can be left outside but must be undercover. You can see an example of this in the picture below.

As you can see from this image the heater is outside however it has cover overhead.

Infrared Heating

Enjoy a BBQ atmosphere all year round! Infrared heating works differently to convection heating, the emitted infrared rays do not heat up air but the objects and people they encounter. This allows you to experience pleasant warmth on your skin and clothing, whilst heat-storing objects such as tables and chairs will absorb the heat and release it as a secondary source.

This heating is also better for allergy sufferers as the heat production runs cleanly, without condensation and blower-free, therefore dust does not rise.

Perfect for the job

Great little heater. Gives off a great deal of warmth and the red glow adds to the atmosphere. It makes the garden welcoming on slightly cooler evenings. Installed at a height of 1.8m on our pergola and the heat can be felt across the whole deck (see pic). Build quality is good and the installation was easy. Reasonably priced and arguably better than other well known, more expensive, brands. Only comment would be that a longer cable would be handy and a little cover to pop over when it’s not in use would make it perfect. Would definitely recommend. 5 stars.

The holy grail of heaters

Initially it was a very difficult decision of what and where to buy some reliable heaters to replace redundant ones in a small church!
Castle Heaters came tops in delivery and price; the big question was, would they be good enough for the church benefactors and most important, the congregation?
Confirmation came through only yesterday from the Custodian, that the church had never been so warm, and that the heaters even emitted additional light in what was normally a gloomy environment!
Everyone it seems was very impressed and over the moon with their new heaters. So a win win for me, and for Castle Heaters. I can definitely recommend this company and this particular product.

Perfect heaters for my needs

Alexander Park

Excellent heat and radiation of same. However the on/off switch is on the fire so it can only be raised as high as one can reach. Fine if you're tall but so great it you are on the short side! 🤔
