Boiler Types We Install in Hounslow

Combi Boilers
Combi boilers work well in smaller Hounslow homes and flats. They heat water straight from the mains when you turn on a tap. You don’t need a hot water tank or a feed tank, which saves space. Modern combi boilers can handle homes with up to 3 bedrooms and 2 bathrooms.

System Boilers
System boilers are great if you use a lot of hot water. They store hot water in a cylinder. This means many taps can run at once without losing pressure. These boilers connect right to the main water supply. No tanks in the loft are needed.

Conventional Boilers
Also known as regular, traditional, or heat-only boilers, these are commonly found in older Hounslow properties built before the 1990s. They use a cold water storage tank (usually in the loft) and a hot water cylinder. They’re good for homes with many bathrooms and lower water pressure.
We install boilers from trusted brands like Worcester Bosch, Vaillant, Ideal, and Baxi. We help you pick the most efficient model for your needs. This can save you hundreds of pounds each year on energy bills.
Our Boiler Installation Process
Initial Assessment
We begin with a thorough evaluation of your property, assessing your hot water needs, existing system, and property layout. This helps us recommend the perfect boiler type and size.
Clear, Transparent Quote
You’ll receive a detailed, no-obligation quote outlining all costs with zero hidden fees. We explain every element clearly so you understand exactly what you’re paying for.
Pre-Installation Preparation
Before installation day, we plan every detail to minimise disruption to your home. We order all necessary parts and prepare protective coverings for your floors and furniture.

Installation Day
Our Gas Safe engineers arrive promptly and begin by protecting your property. For most homes, installation takes just one day. We disconnect and safely remove your old boiler, install the new system, and connect it to your existing pipework (upgrading where necessary).
System Flushing
We thoroughly flush your system to remove any debris or sludge that could affect your new boiler’s performance, a crucial step many installers skip.
Testing and Certification
Every installation includes comprehensive testing to ensure optimal performance and safety. We then register your installation with Gas Safe and provide all necessary certifications.
Customer Education
Before we leave, we show you how to operate your new boiler efficiently, program its controls, and perform basic maintenance. We answer all your questions and provide a user manual for future reference.
Aftercare
Our service doesn’t end with installation. We provide ongoing support and are always available to answer questions about your new system.
