The boiler provides highly efficient space heating and domestic hot water (DHW) in a compact footprint that is easy to install and maintain. When the hot water tap is opened, incoming water flows through the heat exchanger. The heated boiler water from the fire tube heat exchanger prioritises heating the domestic hot water to the desired temperature. When space heating is required, a diverter valve diverts the heated boiler water to the external space heating loop.

What are the main advantages of a boiler?

Combi boilers offer a space-saving choice by combining space heating and hot water supply in one highly efficient appliance They are also easy to install and operate.

Why choose a combi boiler?

There are many reasons why most homeowners choose a combi boiler:

Unlike a system or regular boiler, it is a single combined unit. This means there is no need for a separate water tank or hot water cylinder. And they can usually fit comfortably in a kitchen cupboard. This saves a huge amount of space in your home.

Because they are an all-in-one unit, they are relatively easy to install. Easy installation means faster installation, which equates to cheaper installation.

They provide hot water on demand, so there is no need to use extra energy to keep a storage cylinder warm. And no waiting for the tank to refill after the water runs out.

A combi boiler takes its water supply directly from the mains, which means you get a much more powerful flow of hot water.

Which size suits your needs?

It is important that you get a boiler that is the right size for your home.

By size, we mean the output rating, which is a measure of the boiler’s power. If the boiler is too small, it will not meet your hot water needs. Too big and it will waste energy, causing your heating bills to increase. It is therefore important that the output rating matches your home.

Combi boilers have two output ratings, one for central heating and one for domestic hot water.

In addition to your need for hot water, it must also be able to keep up with the strength of the mains pressure as it flows through the boiler.( tablo altındaki yazı)
