Types of Boilers We Install
At Giants Plumbing & Heating, our certified and experienced heating engineers in Feltham specialise in installing many boilers, including combi, conventional, and system boilers. Whether you’re upgrading to a more energy-efficient model or switching to a different type of boiler to better suit your home’s heating needs, we’ve got you covered.
Conventional Boiler Installation
Conventional boilers, also known as regular or heat-only boilers, are best suited for larger homes with higher hot water demands. This system requires a hot water cylinder and a separate tank, typically stored in the loft, to supply water to your taps and radiators.
It’s a reliable choice for properties with multiple bathrooms, ensuring steady water pressure and heating throughout.


System Boiler Installation
System boilers offer a perfect balance, combining the advantages of combi and conventional systems. Unlike regular boilers, they don’t need a cold water storage tank, as components like the pump and expansion vessel are built in.
When paired with a hot water cylinder, they provide plenty of hot water to taps and radiators, making them ideal for medium to large homes.
Combi Boiler Installation
Combi boilers are a popular choice for modern households. They deliver hot water on demand without needing a storage tank or shower pump. Compact and efficient, they’re ideal for small properties where space is at a premium.
Combination boilers save space and energy, as they do not require bulky water tanks. This makes them a smart solution for homes seeking convenience and cost-effectiveness.

Gas Combi Boilers
Gas combi boilers are budget-friendly and ideal for homes connected to the gas network. They provide instant heating and hot water, making them a reliable choice. Their efficiency helps reduce energy bills.
Oil Combi Boilers
Oil combi boilers are great for homes without a gas supply. They require an outdoor oil tank but are highly energy-efficient, making them perfect for rural properties.
LPG Combi Boilers
LPG boilers are suitable for homes off the gas grid, offering similar efficiency to natural gas systems. They need an LPG storage tank for fuel. These boilers are a reliable solution for remote areas.
Electric Combi Boilers
Electric boilers are compact and easy to install, making them ideal for smaller homes. They are eco-friendly but heat less water than fuel-based systems, making them perfect for properties with renewable energy sources.

FAQs About Boiler Installation And Maintenance
Absolutely! Just let us know in advance, and we’ll ensure the engineer arrives prepared to install a thermostat or timer during your boiler service. This addition can enhance your system’s efficiency and control.
Regular maintenance is key. Schedule your annual boiler inspection and servicing to ensure a safe, reliable, and energy-efficient heating system. Timely checks also help avoid costly repairs in the future.
Not always. If your current radiators are in good condition, there’s no need to replace them. However, upgrading during the boiler installation is wise if they’re outdated or faulty. This saves time and effort since the system will already be drained for the boiler replacement.
A magnetic filter protects your boiler by trapping metal debris that could clog your system and damage the heat exchanger. While it doesn’t catch non-magnetic particles, flushing the system when necessary ensures optimal performance. Installing one is highly recommended for long-term efficiency.
We aim to provide same-day surveys, subject to availability. While emergency services are offered, boiler installations don’t always qualify as urgent. Contact us, and we’ll do our best to accommodate your request.
Installation times vary:
- Like-for-like replacement: 4–6 hours
- Relocation or new installation: 1–2 days
- Switching boiler type: 2–3 days
- Changing fuel type or complex installations: 3–4 days
Our team will provide a detailed timeline during the survey.
Not all plumbers are qualified to install boilers, which requires gas-safe registration. Every plumber we work with is fully certified and trained to install boilers safely and to the highest standards.
This depends on the scope of the work. We’ll inform you beforehand if interruptions occur so you can plan accordingly. Typically, hot water is unavailable for at least a day. If you have an electric shower or immersion heater, this can reduce downtime.
