This article will look into answering commonly asked questions like, [how long it takes to install a combi boiler](https://www.trustedboiler.co.uk/combi-boiler-installation) and where you can install a combi boiler. Here’s our insider guide. ## **Quick Combi Swap** If you’ve already got a combi boiler on the property, you can breathe a sigh of relief. Replacing a worn out or broken combi boiler for a new combi boiler in the same location is a quick process. Skilled engineers can usually complete the work in between four to six hours. This means minimal interruption for tenants and straightforward project-management for new landlords.

This money saving strategy requires a few adjustments to pipework but will repay you long term by making your properties more attractive to longer term tenants. In most cases, this is relatively minor and takes around a day or in a few, more complex cases two days. This timeline includes removing the old boiler, altering the system, and installing the new boiler. ## **Boiler Relocation** Moving a boiler is often key to maximising space. The timescale of this depends on how radical the move is, which affects how much additional pipework is needed. As a general rule, expect a boiler relocation to add about half a day to the installation time. In most cases, this will mean that the entire project takes a very cost efficient day and a half. ## **New Combi Boiler Installation** If the home has never had a boiler, installation times can vary. Installations from scratch of a combi boiler can take around one to two days. This includes installing the new pipework, as well as drilling any required holes for features such as condensation pipes. The ideal location for a new combi [boiler installation](https://www.trustedboiler.co.uk/combi-boiler-installation) would be either the kitchen or utility room, although a new combi boiler can be installed almost anywhere. ## **Factors Affecting Installation Time** While the majority of combi boiler installations in rental properties are very straightforward, some are more difficult than others. Heating engineers can find unexpected issues such as poorly installed pipework, which makes our job a little harder. Some properties have complex or bizarre system configurations, which can require a bit of creative thinking to work with. ## **Find Out More** If you are a [landlord who is thinking about improving energy efficiency](https://www.trustedboiler.co.uk/landlords) and cost-savings by installing a new combi boiler, upgrading an old combi boiler, or who is wondering where to install a boiler, we can help.
