Types of Gas Heaters

Well, gas heaters can be divided into three main categories viz. (1) Flued, (2) Unflued & (3) Portable gas heaters that are explained as below:

1. Flued Gas Heaters

This kind of gas heater is integrated with a flue pipe that transmits exhaust gases from your heater outdoors, protecting your space from being polluted with emissions. Above all, remember that this type of flued-gas-heaters needs professional installation and they aren’t portable (moveable).

2. Unflued Gas Heaters

This type of gas heaters are considered movable; however, they aren’t considered portable because they’re bulkier than the portable modes available on the market. People who are staying in a rented property will benefit from this type of gas heater as it provides a heating solution for them to sit and relax in their living rooms all around the year.

3. Portable Gas Heaters

This type of gas heaters are specifically designed for easy manoeuvrability, so they can be moved from one room to another or pack them away during those summer months, as well as, you can take them with you to work or at a holiday destination if you so desire.

Agreed, they’re pricier variant compared to electric models available on the market, but they are less costly to operate and the newest models come integrated with vital Safety Turn OFF prompts to offer you complete peace of mind particularly, if you’ve young ones in the household.
