Boiler Installation FAQs
How long does it take to complete standard new boiler installations in Ashtead?
The time to install new boilers varies. Simple installations may take one day, while more complex jobs, like switching to a different type of boiler or making modifications, could take up to three days. The type of boiler plays a factor, as well. After assessing your situation, the heating engineer will provide the expected cost and duration of the entire process.
Do you install all types of boiler?
Rowlen provides services specifically for gas boilers only. All our engineers are carefully trained and highly qualified to work with all types of gas boilers such as system boilers, conventional boilers, and combi boilers.
Whether you wish to have a Worcester Bosch combi boiler or a new Vaillant system boiler installed, our boiler fitters have the knowledge and expertise to install it with accuracy and precision.We understand that each type has its own unique requirements so we tailor our approach to suit the specific needs of your boiler. When you choose us, you can trust that your boiler is in capable hands, regardless of its type.
Just a heads-up, though! We don’t service oil boiler, LPG (liquified petroleum gas) boiler, and electric boiler.
How do I know which type of boiler best fits my home?
Choosing the right boiler can be tricky especially with the stream of new, modern boilers in the market. The perfect boiler for your home boils down to your specific needs, your budget, and the size of your property.
Combination boilers, or combi boilers, are space-saving and energy-efficient, ideal for small to medium homes as they combine hot water and heating in one unit. In contrast, condensing boilers enhance efficiency by capturing and reusing heat that would otherwise be lost.
Regular boilers, though reliable, are better suited for larger heating needs and homes with a traditional hot water system, but they require more space. System boilers are ideal for homes with multiple bathrooms, as they use hot water cylinders to meet higher demand. For homes without gas, electric boilers provide a compact and eco-friendly alternative, while LPG and oil boilers are the best options for off-grid homes, requiring a fuel storage tank.
How do I avoid the need for frequent boiler repairs on my newly installed boiler?
To prevent unexpected breakdowns and having to book for frequent emergency boiler repair service, a regular boiler servicing is the most cost-effective way in avoiding such hassle.
At Rowlen, our annual boiler service keeps your boiler running in high efficiency, reducing the risk of issues, especially during colder months. Investing in professional maintenance not only ensures your home’s warmth, safety, and comfort but also improves energy efficiency, saving you money on bills.

Why are gas safety checks important?
A gas safety check is a regular safety inspection performed to make sure your gas appliances, like commercial boilers, are running efficiently. These checks are of utmost importance for safety reasons if you own gas boilers since these help prevent dangers like gas leaks and carbon monoxide poisoning, helping to keep your commercial premises safe and secured.
Only a fully qualified Gas Safe registered engineer can perform these inspections in compliance to the national safety standards. Plus, we’ll provide you with a gas safety certificate, which is a must-have for all landlords and property owners to meet the relevant regulations and other legal requirements for commercial properties.
