Replacement Boilers & Heating Systems

 

 

 

Why choose a combi (combination) boiler?

A combi boiler is both a high-efficiency water heater and a central heating boiler, combined (hence the name) in one. You do not need a separate hot water cylinder. You don’t have to wait for the hot water to heat up in the cylinder. A combi boiler is also very suited if you have limited space in the property. Hot water also comes through your hot water tap at the same speed as your cold water. It also takes less time to install! The water is heated on demand instead of storing hot water which can sometimes be wasted. 

There are some disadvantages to having a combi boiler. You do not have electrical back up with the immersion heater and you will not have an airing cupboard with cylinder. The water flow will also be affected if you are using more than one tap so it is generally not a suitable option if you have more than one bathroom in the property.

Why choose a regular boiler?

A Regular boiler is also referred to as a ‘traditional’ or ‘conventional’ boiler. The system includes a boiler, controls and a a hot water cylinder which is normally supplied by a cold water storage cistern located in your loft space. The system also has a feed and expansion cistern in the loft.

The water from the tanks in the loft sends cold water down to the cylinder which is normally located in the airing cupboard. The condensing boiler will heat the water in the cylinder and your pump will circulate the hot water around the pipes and in turn heat the radiators. The system will also have an electric immersion for backup. There are some disadvantages to having this type of boiler it does take time to heat the water in your cylinder and more space is required for this type of system.

Why choose a system boiler?

A system boiler heats your central heating system directly and produces hot water for your cylinder. You can have an open vented hot water cylinder or a pressurised unvented hot water cylinider. 

Some of the individual components of the heating and hot water system are built into a system boiler and the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder.  There is no need for a feed and expansion cistern.

There are some disadvantages to having this type of boiler it does take time to heat the water in your cylinder and more space is required for this type of system.
