The Alliance CFM team recently completed a boiler replacement, removing an existing Glow-worm boiler and installing an Ideal Vogue combi boiler in its place.
When replacing a boiler, it’s important to make sure the new system is suited to the property’s heating and hot water requirements. Boiler specification, the condition of the existing system and the demands of the property all need to be considered before installation.
What Does a Combi Boiler Do?
A combi, or combination, boiler provides central heating and heats mains water on demand, without storing hot water in a separate cylinder. This makes it different from conventional and system boiler arrangements that use a hot water cylinder.
Whether a combi is the right choice depends on the individual property. Available water flow and pressure, heating demand, hot water requirements and the existing system all need to be considered when specifying a replacement.
Repair or Replace an Existing Boiler?
A boiler developing a fault does not necessarily mean it needs replacing. Depending on its condition and the nature of the problem, repair may still be the appropriate option.
Replacement may become worth considering when an existing boiler is ageing, becoming unreliable or requiring repeated repairs. An assessment of the boiler and wider heating system provides a better basis for making that decision than age alone.
What Should Be Checked When a New Boiler Is Installed?
A replacement boiler needs to be correctly installed and commissioned, but attention should also be given to the existing heating system.
The requirements will vary between installations, but system condition, water quality and controls are among the factors that may need to be considered. Following the boiler manufacturer’s installation and commissioning instructions is also important for correct operation and warranty requirements.
Frequently Asked Questions
Can I replace my old boiler with a combi boiler?
Potentially, but a combi boiler isn’t suitable for every property or heating system. The existing system, available mains water flow and pressure, and the property’s heating and hot water requirements should be assessed before deciding whether a combi is appropriate.
How long does it take to replace a boiler?
It depends on the work involved. Replacing a boiler with a similar type in the same location will generally be more straightforward than changing the type of heating system, relocating the boiler or carrying out additional alterations. Our engineers can give a realistic timescale after assessing the installation.
What size combi boiler do I need?
The required output again depends on the property’s heating demand and hot water requirements. Boiler selection should therefore be based on an assessment of the property and system rather than simply choosing a particular output based on the number of bedrooms.
Do you need to flush the heating system when installing a new boiler?
The existing system needs to be appropriately cleaned and treated when a replacement boiler is installed, following the relevant standards and boiler manufacturer’s requirements. The method required will depend on the condition of the system; a powerflush is not automatically necessary for every boiler replacement.
