Combi gas boilers are also very economical to operate. The models are designed to produce heat on demand (for hot water or to heat one’s home). Their high efficiency means they are more environmentally friendly than many traditional heating systems. Besides, they are tankless, which means that there is no energy wasted.

Cons of Gas Combi Boilers

One of the main drawbacks is the fact such boilers aren’t suitable for large homes with several bathrooms, as they’re limited to how quickly the water can be heated and struggle to heat large houses. Still, they are available in different sizes, meaning you can choose the proper one, if your place is not too big.

One more drawback is that the water pressure is reduced, if one needs hot water from several taps at once. Besides, combi boilers are pretty vulnerable to hard water, and it’s highly important to take care of them regularly.

Though there are a few cons, pros still gain the upper hand over them. So, make your choice wisely.
