Gas Boiler Installation in Essex & Hertfordshire

The time it takes for a boiler installation can vary depending on the type of boiler being fitted and the complexity of the job. For most straightforward replacements — such as swapping an old combi boiler for a new one in the same location — the process can usually be completed within a day. However, if you’re changing from one type of boiler to another (e.g. from a regular to a system boiler), or relocating the boiler entirely, it may take longer.

At Rothwells Heating, we handle everything from the removal of the old boiler to installing the new unit, pipework adjustments, and configuring the thermostat and thermostatic radiator valves. We also provide a full system demonstration, ensuring you understand how to use your programmer, room thermostat, and other controls to get the most out of your new system.

Every job we take on is tailored to your home, and we’ll explain exactly what’s included during your free quote.

Choosing the right boiler for your home depends on several factors: the size of your property, how many bathrooms you have, and your demand for heating and hot water. The three main types of boiler are combi boilers, system boilers, and regular (conventional) boilers.

• A combi boiler is perfect for smaller homes or flats. It provides hot water on demand without the need for a water tank, saving space and energy.
• System boilers are ideal for medium to large homes. They work with a cylinder to supply hot water and provide consistent pressure, even when multiple taps are in use.
• Regular boilers suit older homes with existing traditional heating systems.

At Rothwells Heating, we assess your household needs and help you choose the most energy efficient system. Whether it’s a Worcester Bosch combi or a high-capacity system model, we’ll make sure you get the best boiler installation for comfort and performance.

On average, a modern boiler can last around 15 years with proper maintenance, but this lifespan can vary depending on usage, water quality, and how well the boiler has been serviced over the years. If your current boiler is more than 10–15 years old, you may start noticing issues like inconsistent heating and hot water, rising energy bills, or frequent boiler repair needs.

Rather than continuing to pay for breakdowns and inefficiencies, many homeowners find it more cost-effective to have the boiler replaced with a new energy efficient model. Newer boilers are better built, have improved safety features, and offer significantly lower running costs — especially when combined with smart thermostat and thermostatic radiator controls.

At Rothwells Heating, we offer honest assessments and expert advice to help you determine the right time to replace your boiler. If it’s time, we’ll guide you through the process with transparency and care.

Yes, a professionally installed, energy efficient boiler can significantly reduce your energy bills, especially if you’re replacing an old, inefficient model. Over time, older boilers can lose their ability to burn fuel cleanly or heat water efficiently, meaning you pay more for less output.

Modern boiler installation options — including Worcester Bosch models — are built to high standards, often achieving A-ratings for energy performance. When combined with accurate thermostat and thermostatic radiator valves, or even a smart programmer and room thermostat, you can manage your home’s temperature far more efficiently.

At Rothwells Heating, we assess your home’s heating demands and recommend the best boiler for your home, ensuring it meets your daily usage without waste. We also make sure to install including all necessary components to optimise performance. As a result, many of our customers enjoy lower monthly bills and better comfort all year round.

Most modern boiler installations include advanced controls to help you manage your heating and hot water more efficiently. These controls typically include:

• A programmer that lets you set on/off times for heating.
• A room thermostat that monitors and adjusts your indoor temperature.
• Thermostatic radiator valves (TRVs) that regulate heat on a room-by-room basis.

Some installations may also include smart controls, such as app-based thermostats that give you full control of your heating even when you're away from home.

At Rothwells Heating, we ensure your boiler is fitted with controls that suit your lifestyle and property. Our engineers will show you how to use your thermostat and thermostatic settings to maximise comfort and energy efficiency. These features not only improve usability but can contribute to significant savings on your energy bills when used correctly.
